Device construction:

(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 AC current. This alternating current is fed into your home system or into the public grid and synchronized with the voltage that is used there.

The inverter has been designed exclusively for use in grid-connected photovoltaic systems. It cannot generate electric power independently of the grid.

The design and function of the inverter provide a maximum level of safety during both installation and operation.

The inverter automatically monitors the public grid. Whenever conditions in the electric grid are inconsistent with standard conditions (for example, grid switch-off, interruption), the inverter will immediately stop operating and interrupt the supply of power into the grid.
Grid monitoring is carried out using voltage monitoring, frequency monitoring and monitoring islanding conditions.

The inverter is fully automatic. Starting at sunrise, as soon as the solar modules generate enough energy, the inverter starts monitoring grid voltage and frequency. As soon as there is a sufficient level of irradiance, the solar inverter starts feeding energy into the grid.
The inverter ensures that the maximum possible power output is drawn from the solar modules at all times.
When there is no longer sufficient energy available to feed power into the grid, the inverter shuts down the grid connection completely and stops operating. All settings and recorded data are saved.

If the inverter temperature exceeds a certain value, the inverter automatically derates power output for self-protection.
The cause for a too high inverter temperature can be found in a high ambient temperature or an inadequate heat transfer away (eg for installation in control cabinets without proper heat dissipation).

1. General

The inverter is fitted with the following safety function as required by UL 1741 and the National Electrical Code:

Insulation monitoring
In photovoltaic systems with ungrounded solar modules, the inverter checks the resistance between the photovoltaic system's positive or negative pole and the ground potential. In the case of a short circuit between the DC+ or DC- cable and the ground (e.g., due to poorly insulated DC cables or faulty solar modules) the inverter disconnects from the grid.

1. General

The inverter is equipped with integrated arc detection/interruption, which detects and extinguishes serial arcs.

For example, a serial arc can occur after the following errors or situations:

• Poorly-connected plug connections on the solar module
• Poor or defective cable connections on the solar module side, which enable a connection against the earth potential
• Defective solar modules due to problems in the junction box or production errors, such as high resistance solder connections in individual solar cells
• Cables incorrectly connected to an inverter’s input terminals

If a serial arc is detected, the power is switched off and the grid power feed operation is interrupted. A state code is shown on the display. The state code on the display must be manually reset before the grid power feed operation can be resumed.

The power shutdown also extinguishes the serial arc.

1. General

This enables you to know immediately if there are any malfunctions in the inverter or the photovoltaic system or any installation or operating errors.

Whenever the system self diagnosis has identified a particular issue, the respective status code is shown on the screen.

IMPORTANT! Status codes may sometimes appear briefly as a result of the control response from the inverter. If it subsequently continues to operate normally, there has not been a system error.

1. Status Diagnosis and Troubleshooting

• check the AC voltage at the inverter's connections:
  the AC voltage must be 208–240 V (+10% / -12%) according to the grid.

1. Status Diagnosis and Troubleshooting

Status codes in class 1 are typically temporary. Their cause lies in the grid.

Example: The grid frequency is too high and the inverter is not permitted to feed energy into the grid because this would not comply with a standard. No device fault has occurred.
The inverter will first respond by disconnecting from the grid. Then, the grid will be checked for the duration of the observation period stipulated. If, after the end of this period, no further defect is identified, your inverter resumes operating and feeding energy into the grid.

The GPIS soft start function is activated depending on the country setup:
According to national guidelines, the output power of the inverter increases continuously after a shutdown due to an AC error.

Class 3 comprises status codes that may appear during feed-in operation and that do not cause a permanent interruption of the grid power feed operation.

After automatic disconnection from the grid and waiting for its conditions to return to those stipulated, your inverter will try to resume grid power feed operation.

1. Status Diagnosis and Troubleshooting

Class 4 status codes may require the intervention of a trained Fronius service technician.

1. Status Diagnosis and Troubleshooting

Class 5 status codes generally do not impair grid power feed operation, but can lead to limitations. They will be displayed until the status code is acknowledged by pressing a key (the inverter, however, continues working normally in the background).

1. Status Diagnosis and Troubleshooting

Class 7 status codes concern the inverter control unit, configuration and data recording, and can directly or indirectly affect grid power feed operation.

1. Status Diagnosis and Troubleshooting

• An error appears frequently or for a long period of time
• An error appears that is not listed in the tables

1. Status Diagnosis and Troubleshooting

When operating the inverter in extremely dusty environments:
when necessary, clean the cooling elements and fan on the back of the inverter and the supply air openings in the mounting bracket using clean compressed air.
