(ch) A high output power of the Sunny Island inverter when the battery state of charge is low may lead to the Sunny Island not being able to raise the AC voltage in the stand-alone grid to the AC voltage of the generator. The Sunny Island cancels the synchronization.
• To charge the battery, reduce the power of the loads.
The generator voltage might not be within the thresholds for voltage and frequency.
• Check whether the symbol * is displayed permanently in standard mode.
If the symbol * is not displayed, ensure that the fuse is not defective or the circuit breaker is activated.
If the symbol * is not displayed permanently, the generator voltage is sporadically outside the thresholds.
– Set the thresholds for voltage and frequency of the generator voltage (see the Sunny Island inverter installation manual).
If the symbol * is displayed permanently, the Sunny Island is in the warm-up period or is blocked for connection.
Useful hint: Tip: Check whether the Sunny Remote Control displays the ” ! ” warning symbol in standard mode.
All work on the inverter and the cabling of the PV array must be carried out by an electrically qualified person.
