Xantrex SW Series Inverter Chargers

The Xantrex SW Inverter/Chargers are designed to provide homes with a completely independent power supply, SW4048 Plus Inverter/Charger combines an inverter, battery charger and dual transfer switch in one package. The SW Plus offers continuous power output of 4.0 kVA. The SW Plus provides AC power for household appliances and DC power to charge batteries. As part of an off-grid renewable power system, it converts all forms of renewable energy into utility grade household power.


  • Available in 4000 and 5500 watt models.

  • Utility grade, sine wave power.

  • Durable construction for long life under extreme environmental conditions.

  • Three-stage battery charging (bulk, absorption, and float) and battery equalization with remote

  • temperature sensor for increased performance.

  • Programmable control module with LCD display and LED indicators.

  • Low idle current (less than one watt) conserves energy when no loads are present.

  • Soft-start capability for starting heavy loads.

  • Built-in starting control circuits for two and three-wire generator starting systems.
