After automatic disconnection in battery protection mode, the Sunny Island can no longer be started?
(ch) Charge the battery only when the Sunny Island cannot be switched on (see Operating Manual, Section “Charging the Battery after Automatic Shutdown in Off-Grid Systems (Emergency Charge Mode)”).
- Switch off all loads.
- If there is a generator in the system, start the generator manually. When doing so, observe the warm-up time of the generator. Five minutes without charge current can result in disconnection of the Sunny Island inverter.
- If sufficient power is available from the generator or the AC sources in the stand-alone grid, e.g., sufficient solar irradiation for PV inverters, switch the Sunny Island on. AC sources in the stand-alone grid can start feeding in electric current only once the Sunny Island has been started and is in operation.
All work on the inverter and the cabling of the PV array must be carried out by an electrically qualified person.
