Solis Battery Voltage Alarm | Faisalabad, Lahore

Solis hybrid shows OV-Vbatt or UN-Vbatt (battery voltage)

Short answer

OV-Vbatt means the Solis inverter detected battery overvoltage and UN-Vbatt battery undervoltage. Solis asks to verify battery voltage at the inverter connection and contact the battery maker; on off-grid models it also suggests checking whether the battery breaker has tripped and whether battery settings are reasonable.

What you will see
