Inverter mode
If the inverter mode is activated, the batteries will not be charged despite available
shore power . If the inverter is switched off, the batteries will be charged by the charger
in case of available shore power .
UPS mode
Scenario 1: Shore power available during daytime
T0 – T5: (bypass mode)
If the system is started and shore power is available, the bypass mode starts automati-
cally, the inverter mode is deactivated and all devices are supplied with shore power . As
long as the battery voltage is >11 V*, the integrated charger remains deactivated in this
phase . Everything is charged by solar power .
The solar power charges the batteries with a IUoU charging characteristic (max .
14,4 V*) and remains afterwards at a maintenance-charge voltage of 13,8 V* .
Scenario 2: Shore power fails at night
T5 – T6: (UPS function/inverter function)
If the shore power connection is disconnected and no solar power is available the
device switches automatically from bypass mode into inverter mode . Due to the
disconnection of solar and shore power the batteries are used for power supply and
discharged until max . 11 V* .
Scenario 3: Shore power returns at night
T6 – T9: (Charging with charger)
As soon as shore power is available, the device switches immediately to bypass mode
and the batteries are charged by the integrated charger . If there is no solar power availa-
ble but shore power, the batteries will be charged to a 100% .
Scenario 4: Shore power fails a second time at night
T9 – T10: (deep discharge of batteries in emergencies)
If the shore power connection is disconnected a second time and there is no solar
power available (at night for example) and the device switches into inverter mode, the
batteries are discharged to 10,5 V* and then disconnected .
Scenario 5: Simultaneous charging according to Scenario 4
T10 – T11: (simultaneous charging after emergency)
