Enable secure power supply operation
To supply the loads with energy in the event of utility grid failure, you can enable the secure power supply operation as follows.
To check the secure power supply operation, proceed as described in this section. Disable the secure power supply operation afterwards ( > Disable secure power supply operation).
Procedure:
- If no load is connected to the outlet, connect a load.
- Turn the switch of the outlet to secure power supply operation.
- Wait one minute.
- The inverter commences secure power supply operation. Once the inverter supplies the outlet, the green LED flashes (1.5 s on and 0.5 s off).
- If the green LED is not flashing, it is likely that the battery's state of charge (SOC) is too low and the following steps must be performed:
Ensure that the outlet's switch is set to secure power supply operation.
Connect a load with lower power consumption to the outlet.
- If no voltage can be measured at the outlet, ensure that the switch of the outlet is set to secure power supply operation, and that the switch, outlet and control light for secure power supply operation are correctly connected.
