Which are the AC Filters and AC Measures Protections and AC Surge Arresters
Protections and contactor.
In normal operation, every switch has to be closed except of contactor circuit.
If there is and alarm, signal circuit has to be checked to verify where the circuit
is opened. There may be several causes, as broken circuit cables, shotdown
protection, fused Surge Arrester, connector.
0200H,
DC circuit protection.
It appears when an DC protection has shotdown.

4000H,
Overvoltage at panels input.
It informs about a voltage out of range in PV input.
A voltage over 600 Vdc damages the inverter.
8000H,
Very low voltage at panels input.
It informs about a voltage out of range in PV input.
The inverter will wait till the voltage reaches the necessary value to connect.
