The ST series of inverters from Cotek offer stand-alone power, with an AC transfer switch that is suitable for RV, marine, and emergency applications.

The inverter supports two modes:

Off-line mode: AC output will be supplied through the AC bypass mode during normal operation. Upon AC input failure output power will switch to the inverter, supplied from DC battery power. Once AC is restored the unit will switch back to AC bypass mode.

On-line mode: AC output power will be supplied from DC (battery) during normal operation. Should the DC source or inverter fail, the unit will switch to bypass mode, supplying power from the AC input. Once DC power is restored the unit will revert back to inverter mode.
