@MarkandCynthia posted:I am looking at getting the Renogy 3000w unit this spring. I was curious why the Renogy inverter needs to turned on to run shore power. If you have a automatic transfer switch why the inverter has to be on to get shore power. Maybe I am not understanding how most inverter setups are designed, but I thought it was not necessary. Thanks

Mark, I had a 2000 watt Renogy - just an inverter, no charger - the only wiring connection from it was AC wiring going into my stand alone PD ATS. I did not need the unit turned on with shore power.
I replaced that setup recently with a Kisae 2000 watt inverter/charger with a built in ATS. Wiring is different now of course with an AC line to and from the unit. The Kisae automatically powers up when I'm on shore power, I'm figuring that it needs to monitor the juice running through and turn on/off fans as necessary.
I was expecting a simple pass through, but I can see why the unit needs to be on.
