Overload protection
When you have a power overload on the output load, for poker between 3000-3450W, the inverter can deliver
power continuously for 3 minutes; then, if the overload condition persists, the overload protection is activated and
the AC output is disabled. If the power exceeds 4500W protection is activated almost immediately, in about 10sec.
To restore the normal state of operation, the inverter must be switched off and then on again. Before restoring, you
can read the cause of failure from the visual indication of the load:
