If a relay has been assigned both a battery state-dependent control and a
special function, only the special function is performed!
Exception: To start the generator via K1 the Sunny Island will abide by
the settings of parameters 710 to 715.
The relays are controlled in regular operation only. If the Sunny Island is
switched into standby mode, the AC voltage is missing or an error state
occurs, all relays are dropped out after a short period of time, even when
switched to “ON” in manual controlled mode
“PARREL“ (3+7)
