The triple battery protection system is designed to prevent deep discharge and battery depletion.
If the measured DC voltage falls below the set value, the compressor is automatically shut off to prevent draining the battery.
With an AGM battery, the protection level should ideally be set to High, as AGM batteries are sensitive to deep discharge and low voltage significantly reduces their lifespan.
With a lithium battery (LiFePOâ‚„), the protection level can be set lower, since lithium batteries tolerate deeper discharge better and are additionally protected by an integrated BMS against undervoltage.
