Xantrex SW Inverters

The Xantrex (formerly Trace Engineering) SW Series inverter-charger is probably the most popular off grid and back up power inverter in the world. They are also able to be grid tied or utility connected with the option of the GTI Grid Tie Interface.

They come in 4000 watt and 5500 watt output, and 24 VDC and 48 VDC battery voltage. They have a full battery charger and AC transfer switch built in. With 2 AC inputs you can have a generator and the utility grid connected at the same time. There is full generator start control built in including fully user adjustable set points and all necessary relays.

The user menu is incredibly easy to use and integrated into the front panel. These inverter-chargers have been used for years and have performed well all over the world.

I have seen a few fail but that is understandable with the amount of these that have been manufactured. I don't know the failure rate but almost all failures were due to abuse or improper installation. I've seen them where mice and rodents were allowed to get inside and chew up wires and destroy internal parts. I've seen them where they were subject to extreme moisture or even direct water contact, which is not good. But few failures due to manufacturing defects.

My Overall Rating 9\10
