What voltage is the low battery cut off set at? When starting a motor if inlet voltage drops out will it overload? Does it auto reset?

The PW6000-12 has a voltage range of 10.5 to 15 Volts +/- 0.5 volts. If the voltage reaches the outer limits of this range the unit will beep and shut down to protect itself and your appliances. It will not reset automatically, it must be switched off and then back on to resume function.
