Inverter use.

That was my concern. I would be drawing on the batteries and the converter would be trying to charge them at the same time.

It varies. Some are hardwired like the Parallax 7300, which is often also on the same circuit breaker as the receptacles you want live, so using the circuit breaker as a switch doesn't work. In that case, you have to get into the AC panel and find the black wire coming up from the converter to the bottom of the breaker where it joins the black wire coming from the receptacles' circuit.

You snip the converter's black wire and insert a switch (I used a normal household light switch). Now you can switch the converter off and the circuit breaker stays on so the receptacles work.

OR, the converter might have its own breaker to use as a switch. Or, the converter is not hard-wired, but is plugged into a receptacle nearby, so you just unplug it. OR the converter plugs into a receptacle that is hard to get at, so you plug a power bar (with its own switch) into that, and plug the converter into the power bar where you can get at it.

If you want a low cost PSW inverter to run the sewing machine, this is a decent one. ( I have the 2000w version which runs the microwave etc,)
