What’s battery protection mode?
This function is designed to prevent over-discharge and
battery depletion. When the measured DC voltage is
below the Cut-of f value, the compressor will shut of f to
prevent battery depletion. After the voltage is higher than
Start-up value, the compressor will go back to work again.
Improper protection setting or low power voltage may
cause E1 error, please lower the battery protection or
recharge the battery in time.
