State of charge (SOC)
When installed for the first time, the battery will show a predefined SOC of 19%.
This does not correspond to the actual SOC and the battery corrects th eSOC at
the first full charge or discharge. The actual SOC of new modules is about 35%.
Therefore, only perform a module extension if the battery system is close to 35%
SOC. For details see the extension manual (www.eft-systems.de/downloads).

Connect to the Internet
(recommended)
Connect the battery to the Internet using an Ethernet cable.

Checking the correct
operation
The system runs properly if:
- Home shows RUN and Current Alarm shows no entries
- No error messages on the inverter
- Inverter displays voltage and battery charge correctly
- System charges / discharges
