My inverter has undervoltage protection. In other words, when the voltage gets too low, the inverter senses that and shuts down with a diagnostic code for UV. I could look up the value at which it shuts down, but today I am too lazy. In answer to Tuga's question I am doubtful that low batteries will in any way damage the inverter. When they start decreasing the useful time they will carry the load when dry camping and if that time cannot be increased with an equalization, then I think that is a good time to go shopping. Russ
