1What the error means
The inverter sees no grid voltage at its output and is waiting. This usually means a power outage, a tripped fuse or a broken AC connection — not an inverter fault.
2Possible causes
- Power outage
- Tripped fuse or RCD
- Broken or disconnected AC cable
3What to do
- Check the fuses, the RCD and the AC switch.
- Check the connections on the AC cable.
- If normal voltage is present and the fault remains, the inverter's measuring circuit needs to be checked.
