Does anyone know of an dc to ac inverter that has a transfer switch and does NOT contain a charger ?My tiny (xantrex RS400) inverter stopped functioning and its no longer available so I'm looking for a replacement with similar functionality.I need less than 1500w, mostly to run a Flat Panel TV, I dont need another charger (or converter/inverter/charger combo unit) all i really need is an inverter, with a built in transfer switch. Pure sine wave isn't necessarily required since the TV already has its own power supply in it & no other device that i would run is either sensitive enough nor w/out its own power supply such that pure sine wave is necessary (feel free to correct me if I'm wrong here).The inverter needs to have AC pass-thru / transfer switch capability so that when I'm on shore power the inverter isn't being used (or consuming battery power)....rather it should just pass the AC voltage/current thru the unit to the appliance.The Xantrex freedom HF's would be fine (if it didnt have a charger or i could disable the charger).Id even settle for the Xantrex ProSine (2.0) but again its got a built in charger that i don't need.Are there any inverters available (with built in transfer switches) that permit disabling the charger or don't have a charger built in ??

My inverter, Magnum 4024, you can turn the charger on or off, and if you look into it you may find that you can turn off the charger on most inverters. You can get an external automatic transfer switch for around $50. I'm not aware of any low-end, low powered (non-pure sine, 1,000 watts or thereabouts) that have no charger but do have a built in ATS. I picked up a really inexpensive 1,000 watt pure sine inverter last year (around $180) and paired it with a 30 amp transfer switch that I already had to put in my car trailer.Brian

I have and recommend GoPower 300w sine wave inverter.No charger, low idle draw, provision for a remote power switch.300w and 600w MSW available if you must save the money.Careful going over 400w as the 12v supply wire and fuse may need adjustment.Transfer switch if needed

You want a Xantrex Prowatt SW- sine wave, 540, 900 or 1800 watts, no charger,but... you do need to add an external transfer switch.Should be in the $300-350 range for the 540 watt plus xfer.For MSW, I installed a 1kw PRO Series several years ago, MSW, built in xfer switch, detachable control panel. In heavy use every day with no problems.

Go to Don Rowe and get the Xantrex transfer switch for $50 and use whatever inverter you like.

I see now that the ProSine 2.0 has an included remote (which can be mounted on the inverter or the wall) that does permit the disabling of the charger....its a bit more than i wanted to spend (and the reviews of it are fairly consistent/bad).Ive also just learned that the Xantrex PRO XM (1000 or 1800) also provides "pass thru" when on shore power (and does not include a charger function).

Why not leave the stuff that runs on inverter, stay on inverter when on S power.
No transfer switch. It works really good, and really keeps it simple.
