LED warnings

• Inverter LED not lit
If the LED is not lit or does not flash when there is

sufficient solar energy available, there is probably a
fault in the solar panel wiring.
Check the wiring.

• Inverter LED flashes
If the LED flashes when there is sufficient solar

energy available, there is probably no mains power
supply.
Check the earth leakage circuit breaker and the fuse in

the meter cupboard.
• Inverters react differently
At low solar energy levels, the inverters will barely

start up. Minor production variations in the solar
panels and the inverters can lead to one inverter
starting up slightly before the others.
If, at adequate solar energy levels, one inverter is

active and another is in 'Stand-by' mode, the AC
connector is probably either missing or incorrectly
fitted.
Check or fit the AC connector.
