4. Troubleshooting

4. Troubleshooting

4.1. Troubleshooting

Only trained and authorised personnel familiar with electrical systems and safety

issues may work on inverters and electrical installations.

4

Should the inverter not supply energy as expected, go through the checklist before calling service.

1.Check that the grid is properly connected to the inverter and that the mains switch is not switched off.

2.Check that there is sufficient solar radiation to generate power. UPV >250 V

3.Check for shading and loose cables/connections in the PV system.

4.Check whether the voltage of the PV modules are within the expected values. If not go to point 7.

5.Check whether the voltage values of the grid lie within the threshold values. If this is not the case please contact your public utility for technical assistance.

6.If the above-mentionedpoints are OK, wait 15 minutes to find out whether there is a permanent failure.

7.If the PV system still supplies no power to the grid, check the display for:

-PV module voltage, current and power

-grid voltage, current and power

-event text, see log area

Then call service.

In the event of a failure, the red LED will flash and the display will show an event. Refer to the table for event descriptions and recommended actions.

Event text

Description

Remedy

Grid

Grid values are out of range

Check the voltage and frequency values in the display. If values

 

 

are zero, check the circuit-breaker(fuses) and cables. If values

 

 

are outside the applied limits, request technical service from in-

 

 

staller/energy company.

PV

The PV isolation resistance is too

Make a visual inspection of all PV cables and modules. If the event

 

low

occurs frequently, request technical service.

Internal

An internal event has occurred

Make sure airflow over the heat sink is not obstructed. Wait 5 mi-

 

 

nutes. If the inverter does not reconnect (although sufficient irra-

 

 

diance is available) or the event occurs regularly, action must be

 

 

taken. Service inverter.

Fail Safe

Internal or AC installation error

Turn off both AC and DC (PV) power to the inverter. Make a visual

 

 

inspection of the PV installation, if everything is in order, wait 5

 

 

minutes and re-applyAC and DC (PV) power. If the inverter re-

 

 

sumes fail safe operation, action must be taken. Service inverter.

5.Maintenance

5.Maintenance

5.1. Maintenance

Normally, the inverter needs no maintenance or calibration.

Ensure the heatsink at the rear of the inverter is not covered.

5

Clean the contacts of the PV load switch once per year. Perform cleaning by cycling the switch to on and off positions ten times.The PV load switch is located at the base of the inverter.

5.1.1. Cleaning the Cabinet

Clean the inverter cabinet using pressurised air, a soft cloth or a brush.

5.1.2. Cleaning the Heatsink

Clean the heatsink using pressurised air, a soft cloth or a brush.

For correct operation and long service life, ensure free air circulation

-around the heatsink at the rear of the inverter

-to the fan at the inverter base

Do not touch the heatsink during operation.

Temperature can exceed 70°C.

Note:

Do not cover the inverter.

Do not use a water hose, aggressive chemicals, cleaning solvents or strong detergents to clean the inverter.
