EP battery black start capability — allows starting the EPS output from battery alone when both grid and PV are absent.
Common causes
Grid outage and PV not generating (night/cloud)
What to check
STEP 1
To activate Black Start: press POWER button 3 times within 4 seconds. EPS output becomes live from battery. Confirm loads on EPS circuit are within EP battery EPS rating
STEP 2
Black Start remains active until grid returns. When grid returns, inverter will automatically resynchronise. Note: Black Start mode may not be available if battery SOC is below minimum reserve
Escalate if
Black Start cannot be activated when battery SOC is adequate — check EPS wiring and that EPS mode is enabled in Fox Cloud settings
