Running 1 Sol-Ark inverter on 1 eFlex is not compliant with Fortress minimum sizing standards.
If operating with one eFlex, please adjust the following settings:
In the Batt Setup Menu, adjust amperage in the first two tabs - the batt tab and the charge tab.
If waiting on a repair -> change charge/discharge amps to 100A.
All other cases -> change charge/discharge to 60A.
Reminder: Charge deeply discharged eFlex at 10A when recovering below 49V.
