Betrieb oder Lagerung des Geräts außerhalb des angegebenen Bereichs gilt als nicht bestimmungsgemäß.

This document provides detailed information and instructions to ensure that all users can use the device safely and efficiently.

The information is intended for the following groups of people:
- Technical specialists: persons with appropriate qualifications and fundamental electronic and mechanical knowledge, who are responsible for the installation, operation and maintenance of the device.
- End users: persons who want to use the device in daily operation and understand its basic functions.
Irrespective of any qualifications, only carry out the activities listed in this document.
All persons involved in commissioning, maintaining and servicing the device must be appropriately qualified and have knowledge of working with electrical installations.
The definition of professional qualifications and their applicability are subject to national law.

The maximum sound power level of the inverter is specified in the Technical Data.

The device is cooled as quietly as possible with the aid of an electronic temperature control system; this depends on the amount of converted power, the ambient temperature, the level of soiling of the device, etc.

It is not possible to provide a workplace-related emission value for this device because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the room in general.

In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g., when there is equipment that is susceptible to interference at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take action to rectify the situation.

With regard to data security, the user is responsible for:

backing up any changes made to the factory settings
saving and retaining personal settings

Alle verbauten Komponenten in der PV-Anlage müssen miteinander kompatibel sein und die notwendigen Konfigurationsmöglichkeiten aufweisen. Die verbauten Komponenten dürfen die Funktionsweise der PV-Anlage nicht einschränken oder negativ beeinflussen.

HINWEIS!

Risiko durch nicht und/oder eingeschränkt kompatible Komponenten in der PV-Anlage.

Nicht kompatible Komponenten können den Betrieb und/oder die Funktionsweise der PV-Anlage einschränken und/oder negativ beeinflussen.

Nur vom Hersteller empfohlene Komponenten in der PV-Anlage installieren.

Vor der Installation die Kompatibilität von nicht ausdrücklich empfohlenen Komponenten mit dem Hersteller abklären.

Device design:

(1)	Housing cover
(2)	Inverter
(3)	Wall bracket
(4)	Connection area incl. DC main switch
(5)	Data communication area
(6)	Data communication cover

The inverter transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into the public grid synchronously with the grid voltage.

The inverter has been developed exclusively for use in grid-connected photovoltaic systems; it is impossible to generate energy independently of the public grid.

Thanks to its design and the way it works, the inverter is extremely safe both to install and to operate.

The inverter automatically monitors the public grid. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.).
The grid is monitored by monitoring the voltage, frequency and islanding conditions.

The inverter operates fully automatically. As soon after sunrise as there is sufficient energy available from the solar modules, the inverter starts monitoring the grid. When insolation has reached a sufficient level, the inverter starts feeding energy into the grid.
The inverter operates in such a way that the maximum possible amount of power is obtained from the solar modules.
As soon as the power available has fallen below the level at which energy can be fed into the grid, the inverter disconnects the power electronics completely from the grid and stops running. It retains all its settings and stored data.

If the inverter becomes too hot, it automatically reduces the current output power in order to protect itself.
Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).

The Fronius Eco does not have an internal boost converter. This results in certain restrictions in the choice of solar module and string. The minimum DC input voltage (U_{DC min}) depends on the grid voltage. On the other hand, a highly optimised device is then available for the appropriate application.

Utilisation not in accordance with the intended purpose comprises:

Any use above and beyond this purpose
Making any modifications to the inverter that have not been expressly approved by Fronius
the installation of components that are not distributed or expressly approved by Fronius.

Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.

Proper use also includes:

Carefully reading and obeying all the instructions and all the safety and danger notices in the Operating Instructions and Installation Instructions
Performing all stipulated maintenance work
Installation as specified in the Installation Instructions

When designing the photovoltaic system, ensure that all components are operated within their permitted operating ranges at all times.

Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.

Obey the regulations of the power supply company regarding connection methods and energy fed into the grid.

There are warning notices and safety symbols on and in the inverter. These warning notices and safety symbols must not be removed or painted over. They warn against incorrect operation, as this may result in serious injury and damage.

Safety symbols:
	Danger of serious injury and damage due to incorrect operation
	Do not use the functions described here until you have fully read and understood the following documents: These Operating Instructions All the Operating Instructions for the system components of the photovoltaic system, especially the safety rules
	Dangerous electrical voltage
	Wait for the capacitors to discharge.
	To comply with European Directive 2012/19/EU on Waste Electrical and Electronic Equipment and its implementation as national law, electrical equipment that has reached the end of its life must be collected separately and returned to an approved recycling facility. Any device that you no longer require must be returned to your distributor or disposed of at an approved collection and recycling facility in your area. Ignoring this European Directive may have potentially adverse effects on the environment and your health!

Text of the warning notices:

WARNING!
An electric shock can be fatal. Before opening the device, it must be disconnected at the input and output. Wait for the capacitors to discharge (5 minutes).

Symbols on the rating plate:
	CE-Kennzeichnung – bestätigt das Einhalten der zutreffenden EU-Richtlinien und Verordnungen.
	UKCA-Kennzeichnung – bestätigt das Einhalten der zutreffenden Richtlinien und Verordnungen des Vereinigten Königreichs.
	WEEE-Kennzeichnung – Elektro- und Elektronik-Altgeräte müssen gemäß europäischer Richtlinie und nationalem Recht getrennt gesammelt und einer umweltgerechten Wiederverwertung zugeführt werden.
	RCM-Kennzeichnung – gemäß den Anforderungen von Australien und Neuseeland geprüft.
	ICASA-Kennzeichnung – gemäß den Anforderungen der Independent Communications Authority of South Africa geprüft.
	CMIM-Kennzeichnung – gemäß den Anforderungen von IMANOR für Einfuhrvorschriften und die Einhaltung der marokkanischen Normen geprüft.

WARNING!

An electric shock can be fatal.

Danger from voltage at the fuse holders. The fuse holders are live when voltage is present on the DC connection of the inverter, even when the DC switch is switched off. Make sure that the DC side is de-energised before carrying out any work on the inverter fuse holder.

String fuses are used in the Fronius Eco to provide additional protection for the solar modules.
The short circuit current I_sc and the maximum series string fuse data (e.g. maximum series fuse rating) specified in the module data sheet of the respective PV module are crucial in affording the PV modules the correct fuse protection.
The maximum string fuse rating per terminal is 20 A.
The maximum MPP current (nominal current, operating current) I_max is 15 A per string.

If three strings are connected, strings 1.1, 2.1, 2.3 must be used.
If four strings are connected, strings 1.1, 1.2, 2.1, 2.2 must be used.

If the inverter is being operated with an external string combiner box, a DC Connector Kit must be used (item number: 4,251,015). In this case the solar modules are protected externally in the string combiner box, and the metal bolts need to be used in the inverter.

The national regulations regarding fuse protection must be observed. The electrical engineer carrying out the installation is responsible for the correct choice of string fuses.

NOTE!

To avoid the risk of a fire, only replace faulty fuses with new ones of the same rating.

As an option, the inverter can be supplied with the following fuses:

6 x 15 A string fuses on the DC+ input and 6 x metal pins on the DC- input
12 x metal pins

In order to prevent premature tripping of the fuse during normal operation, it is recommended that the following criteria be met per individual solar module string when fusing-protecting the solar module strings:

I_N> 1.5 x I_SC
V_N >/= max. open-circuit voltage of the PV generator
Fuse dimensions: diameter 10 x 38 mm

I_N	Nominal current of fuse
I_SC	Short circuit current for standard test conditions (STC) according to the PV module data sheet
V_N	Nominal voltage of fuse

NOTE!

The nominal current rating of the fuse must not exceed the maximum fuse protection specified in the data sheet supplied by the PV module manufacturer.

If a maximum fuse protection is not specified, then this information must be requested from the PV module manufacturer.

Fronius Solar Net was developed to make system add-ons flexible to use in a variety of different applications. Fronius Solar Net is a data network that enables multiple inverters to be linked up using system add-ons.
It is a bus system that uses a ring topology. One suitable cable is sufficient for communication between one or several inverters that are connected on the Fronius Solar Net using a system add-on.
Similarly, every inverter on the Fronius Solar Net must be assigned a unique number. For instructions on how to assign a unique number, refer to the section SETUP menu item.
Fronius Solar Net automatically recognises a wide variety of system add-ons.
In order to distinguish between several identical system extensions, each one of them must be assigned a unique number.
More detailed information on the individual system add-ons can be found in the relevant operating instructions or on the internet at http://www.fronius.com ® http://www.fronius.com/QR-link/4204101938

Depending on the model, the inverter may be equipped with the Fronius Datamanager plug-in card (8).

Item	Description
(1)	Switchable multifunction current interface. For a more detailed explanation, see the following section Explanation of the multifunction current interface. Use the 2-pin mating connector supplied with the inverter to connect to the multifunction current interface.
(2) / (3)	IN Fronius Solar Net connection / interface protocol OUT Fronius Solar Net connection / interface protocol "Fronius Solar Net" / interface protocol input and output for connecting to other DATCOM components (e.g. inverter, Fronius sensor box, etc.) If several DATCOM components are linked together, a terminating plug must be connected to every free IN or OUT connection on a DATCOM component. For inverters with a Fronius Datamanager plug-in card, two terminating plugs are supplied with the inverter.
(4)	The "Fronius Solar Net" LED indicates whether the Fronius Solar Net power supply is available.
(5)	The "Data transfer" LED flashes while the USB flash drive is being accessed. The USB flash drive must not be removed while recording is in progress.
(6)	USB A socket for connecting a USB flash drive with maximum dimensions of 65 x 30 mm (2.6 x 2.1 in.) The USB flash drive can function as a datalogger for any inverter that it is connected to. The USB flash drive is not included in the scope of supply of the inverter.
(7)	Floating switch contact (relay) with mating connector max. 250 V AC / 4 A AC max. 30 V DC / 1 A DC max. 1.5 mm² (AWG 16) cable cross-section Pin 1 = NO contact (normally open) Pin 2 = C (common) Pin 3 = NC contact (normally closed) For a more detailed explanation, please see section Relay (floating contact switch). Use the mating connector supplied with the inverter to connect to the floating switch contact.

(9)	Cover for option card compartment

The "Fronius Solar Net" LED is on:
the power supply for data communication within the Fronius Solar Net / interface protocol is OK

The "Fronius Solar Net" LED flashes briefly every 5 seconds:
data communication error in the Fronius Solar Net

Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the Fronius Solar Net ring)
Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if there are too many DATCOM components on the Fronius Solar Net and not enough electrical power is available)

In this case, power for the Fronius DATCOM components must be supplied by connecting an additional power supply (43,0001,1194) to one of the Fronius DATCOM components.

To detect the presence of an undervoltage, check some of the other Fronius DATCOM components for faults as required.

After cutting out because of overcurrent or undervoltage, the inverter attempts to restore the power supply in the Fronius Solar Net every 5 seconds while the fault is still present.

Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds.

Recording and archiving data from the inverter and sensor using a Fronius Datamanager and a Fronius Sensor Box:

Data network with 3 inverters and a Fronius Sensor Box:
- Inverter 1 with Fronius Datamanager
- Inverters 2 and 3 without Fronius Datamanager!

= Terminating plug

The external communication (Fronius Solar Net) takes place on the inverter via the data communication area. The data communication area contains two RS 422 interfaces as inputs and outputs. RJ45 plug connectors are used to make the connection.

IMPORTANT! Since the Fronius Datamanager functions as a datalogger, the Fronius Solar Net ring must not include any other datalogger.
There must only be one Fronius Datamanager in each Fronius Solar Net ring.
Fronius Symo 3 - 10 kW: Any other Fronius Datamanagers must be removed and the unoccupied option card slot sealed off using the blanking cover (42,0405,2020 - available from Fronius as an optional extra); alternatively, use an inverter without Fronius Datamanager (light version).
Fronius Symo 10 - 20 kW, Fronius Eco: Any other Fronius Datamanagers must be removed and the unoccupied option card slot sealed off by replacing the cover (item number 42,0405,2094); alternatively, use an inverter without Fronius Datamanager (light version).

Various wiring variants can be connected to the multifunction current interface. However, these cannot be operated simultaneously. For example, if an S0 meter is connected to the multifunction current interface, it is not possible to connect a signal contact for the surge protection device (or vice versa).

Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load impedance)
Pin 2 = max. short circuit current 15 mA, max. open-circuit voltage 16 V DC or GND

Wiring diagram variant 1: Signal contact for surge protective device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option (surge protective device) either outputs a warning or an error on the display. Further information on the DC SPD option can be found in the Installation Instructions.

Wiring diagram variant 2: S0 meter
A meter for recording the self-consumption of each S0 can be connected directly to the inverter. This S0 meter can be positioned directly at the feed-in point or in the consumption branch.

IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to update the inverter firmware.

The S0 meter must comply with the IEC62053-31 Class B standard

Recommended max. pulse rate of the S0 meter:
PV output kWp [kW]	Max. pulse rate per kWp
30	1000
20	2000
10	5000
≤ 5.5	10000

With this meter, dynamic power reduction can be performed in two ways:

Dynamic power reduction by means of inverter
For more information see chapter Dynamic power reduction by means of inverter on page (→)
Dynamic power reduction by means of the Fronius Datamanager 2.0
for more info see: manuals.fronius.com/html/4204260191/#0_m_0000017472

In the Fronius Solar Net ring (a combination of several inverters), the Fail-Safe function prevents inadmissible feeding of the connected inverters in the start-up phase or during operation. For this purpose, a signal is transmitted from the primary inverter with built-in data manager to the secondary inverters (Lite devices).

The function is activated as soon as the data manager fails or the Solar Net connection is interrupted. In this case, the signal is not transmitted to the secondary inverters. All devices switch off with status 710.

The following requirements must be met to enable the Fail-Safe to function correctly:

For all inverters in the Solar Net ring, Fail-Safe Mode must be set to Permanent and Fail-Safe Behaviour to Disconnect.
The inverter with data manager must be located in the last position of the ring line.

Correct wiring

Function in the event of a fault

Faults occur at the beginning and end of the Solar Net ring – the primary inverter stops sending the signal, and secondary inverters switch off with status 710.

Faults occur at the beginning and end of the Solar Net ring or between the connected inverters – the primary inverter stops sending the signal, and secondary inverters switch off with status 710.

Energy companies or grid operators may impose feed-in limits on an inverter. Dynamic power reduction takes account of self-consumption by the household before the power of an inverter is reduced:

A counter for determining self-consumption of the S0 can be connected directly to the inverter – see chapter Explanation of the multifunction current interface on page (→)

A feed-in limit can be set in the Basic menu under Signal input – S0 meter – see chapter Menu items in the Basic menu on page (→).

Setting options for S0 meter:

Grid feed-in limit
Field for entering the maximum grid feed-in power in W. If this value is exceeded, the inverter regulates down to the set value within the time required by national standards and regulations.
Pulses per kWh
Field for entering the pulses per kWh of the S0 meter.

Zero feed-in is possible with this configuration.

When using the S0 meter and power reduction by means of an inverter, the S0 meter must be installed in the consumption branch.

S0 meter in the consumption branch

If dynamic power reduction is subsequently configured using the Fronius Datamanager 2.0 (Inverter user interface - UC Editor menu - Dynamic power reduction), dynamic power reduction must be deactivated using the inverter (Inverter display - Basic menu - Signal input - S0 meter).

Fronius Solar Net Master / Slave switch
To switch from master to slave mode within a Fronius Solar Net ring

IMPORTANT! In slave mode, all the LEDs on the Fronius Datamanager 2.0 plug-in card are off.

The Night Mode parameter under "Display Settings" in the Setup menu is preset to OFF in the factory.
For this reason the Fronius Datamanager 2.0 cannot be accessed during the night or when the available DC voltage is insufficient.

To nevertheless activate the Fronius Datamanager 2.0, switch the inverter off and on again at the mains and press any function button on the inverter display within 90 seconds.

See also the chapters on "Menu items in the Setup menu", "Display settings" (Night Mode).

When starting the Fronius Datamanager 2.0 for the first time,

the Fronius Datamanager 2.0 plug-in card must be installed in the inverter,
or
there must be a Fronius Datamanager Box 2.0 in the Fronius Solar Net ring.

IMPORTANT! In order to establish a connection to Fronius Datamanager 2.0, “Obtain IP address automatically (DCHP)” must be activated on the end device in question (e.g. laptop, tablet).

NOTE!

If the photovoltaic system has only one inverter, steps 1 and 2 below can be skipped.

In this case, starting for the first time will commence with step 3.

1Connect inverter with Fronius Datamanager 2.0 or Fronius Datamanager Box 2.0 to the Fronius Solar Net

2When networking several inverters in Fronius Solar Net:Set the Fronius Solar Net master / slave switch on the Fronius Datamanager 2.0 plug-in card correctly

One inverter with Fronius Datamanager 2.0 = master
All other inverters with Fronius Datamanager 2.0 = slave (the LEDs on the Fronius Datamanager 2.0 plug-in cards and boxes are not illuminated)

3Switch the device to Service mode

Activate the WLAN Access Point via the Setup menu on the inverter

The inverter establishes the WLAN access point. The WLAN access point remains open for 1 hour. The protection switch on the Fronius Datamanager 2.0 can remain in switch position A due to the activation of the WLAN Access Point.

Status codes (state codes), the status of the inverter (e.g. feeding energy into the grid) or Energy Manager functions can be displayed using the floating switch contact (relay).

Setting range

Relay mode / Relay test / Switch-on point* / Switch-off point*

* these are only shown if the "E-Manager" function has been activated under "Relay mode".

Relay mode The following functions can be shown using relay mode: Alarm function (Permanent / ALL / GAF) Active output (ON / OFF) Energy Manager (E-Manager)
Setting range	ALL / Permanent / GAF / OFF / ON / E-Manager
Factory setting	ALL

	Alarm function:
	ALL / Permanent:	Switching the floating switch contact for permanent and temporary service codes (e.g. brief interruption to energy being fed into the grid, a service code occurs a certain number of times a day - can be adjusted in the "BASIC" menu)
	GAF	As soon as GAF mode is selected, the relay is switched on. The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions. Application example It may be necessary to perform phase compensation when using a single-phase inverter at a multiphase site. If an error occurs on one or several inverters and the connection to the grid is broken, the other inverters must also be disconnected to maintain the phase balance. The "GAF" relay function can be used in conjunction with the Datamanager or an external protection device to recognise or signal that an inverter is not feeding in or is disconnected from the grid and to then disconnect the remaining inverters from the grid using a telecontrol command.
	Active output:
	ON:	The floating NO contact is on all the time the inverter is in operation (as long as the display is not dark or is displaying something).
	OFF:	The floating NO contact is off.
	Energy Manager:
	E-Manager:	Further details on the "Energy Manager" function may be found in the "Energy Manager" section.
Relay test Function test to determine whether the floating switch contact switches
Switch-on point (only if "Energy Manager" function is activated) for setting the effective power limit beyond which the floating switch contact is switched on

Factory setting	1000 W
Setting range	Set switch-off point up to the maximum nominal output of the inverter (W or kW)
Switch-off point (only if "Energy Manager" function is activated) for setting the effective power limit beyond which the floating switch contact is switched off

Factory setting	500
Setting range	0 to the set switch-on point of the inverter (W or kW)

The "Energy Manager" (E-Manager) function can be used to activate the floating switch contact in such a way that it functions as an actuator.
Thus, a consumer that is connected to the floating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the feed-in power (effective power).

The floating switch contact is automatically switched off:

If the inverter is not feeding any power into the grid
If the inverter is manually switched to Standby mode
If the effective power is set to < 10% of the nominal output of the inverter.

To activate the Energy Manager function, select the "E-Manager" item and press the "Enter" key.
When the "Energy Manager" function is running, the "Energy Manager" symbol will appear in the top left corner of the display:

When the floating NO contact is off (open contact)

When the floating NC contact is on (closed contact)

To deactivate the Energy Manager function, select a different function (ALL / Permanent / OFF / ON) and press the "Enter" key.

NOTE!

Notes on setting up the switch-on and switch-off points
If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles.

To avoid switching on and off frequently, the difference between the switch-on and switch-off points should be at least 100 - 200 W.

When choosing the switch-off point, the power consumption of the connected consumer should be taken into account.

When choosing the switch-on point, the weather conditions and anticipated insolation should be taken into account.

Application example
Switch-on point = 2000 W, switch-off point = 1800 W

If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter is switched on.
If the inverter output falls to below 1800 W, the floating switch contact is switched off.

This allows useful applications, such as operating a heat pump or an air-conditioning system using as much self-generated power as possible, to be implemented quickly

Due to the variety of USB flash drives available on the market, it cannot be guaranteed that every USB flash drive will be detected by the inverter.

Fronius recommends that only certified, industry-grade USB flash drives are used (look out for the USB-IF logo).

The inverter supports USB flash drives with the following file systems:

FAT12
FAT16
FAT32

Fronius recommends that the USB flash drive employed should only be used for recording logging data or updating the inverter software. The USB flash drives should not contain any other data.

USB symbol on the inverter display, e.g. in display mode "NOW":

If the inverter detects a USB flash drive, the USB symbol will appear in the top right corner of the display.

When inserting a USB flash drive, check whether the USB symbol is displayed (it may also flash).

IMPORTANT! Please note for outdoor applications that conventional USB flash drives are often only guaranteed to work within a restricted temperature range.
For outdoor applications ensure that the USB flash drive also functions, for example, at low temperatures.

With the help of the USB flash drive, end customers can also update the inverter software via the SETUP menu: the update file is first saved to the USB flash drive, from where it is then transferred to the inverter.

Safety instruction concerning the removal of a USB flash drive:
		IMPORTANT! To avoid any loss of data, a USB flash drive may only be removed if the following conditions are met: Only remove a USB flash drive via the 'Safely remove USB / HW' item on the SETUP menu The 'Data transmission' LED has stopped flashing or comes on steady.

The inverter performs a system self-diagnosis that automatically detects many faults that may occur and shows them on the display. This means you are promptly made aware of malfunctions in the inverter or the photovoltaic system, or of any installation or operating faults.

If the system self-diagnosis has detected a specific fault, the associated status code will be shown on the display.

IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's control response. If the inverter then continues working with no sign of any problem, this means that there was no fault.

If the display fails to come on some time after sunrise:

Check the AC voltage on the inverter connection sockets:
the AC voltage must be 220/230 V (+ 10 % / - 5 %) or 380/400 V (+ 10 % / - 5 %).

Class 1 status codes generally only arise momentarily and are caused by the public grid.

Example: The grid frequency is too high and the inverter may not feed any energy into the grid owing to a standard. There is nothing wrong with the device.
The initial response of the inverter is to disconnect itself from the grid. The grid is subsequently checked during the stipulated monitoring period. If no further problem has been detected by the end of this period, then the inverter will resume feeding energy into the grid.

The GPIS SoftStart function is activated according to the country setup:
After cutting out due to an AC error, the output power of the inverter is continuously increased in line with the national guidelines.

Code	Description	Behaviour	Remedy
102	AC voltage too high	Following careful testing and when the grid conditions are within the permissible range again, the inverter will resume feeding energy into the grid.	Check grid connections; if this status code keeps recurring, contact your system fitter

105	AC frequency too high
106	AC frequency too low
107	No AC grid
