Designed to provide homes with a completely independent power supply, the SW 4048 offers sinewave, utility grade output power, high capacity battery charger, high surge current ability, and easy installation. The SW 4048 inverter/charger can be configured as a stand-alone unit and work in conjunction with your generator to handle loads too large for the generator alone. With the use of the GTI option, it can act as utility interactive inverter, sending excess power back into the grid.
When the utility fails, the SW 4048 instantly supplies AC power to critical loads. When the utility power returns, it can automatically recharge your batteries in preparation for the next power interruption
This inverter has been discontinued. We recommend XW4548 or MS4448AE as an alternate choice.
