WSS Outdoor 4400 Watt USA Power Central 48VDC9444480


With 10.1 kwh of storage capacity, the compact WSS Outdoor 4400-watt Power Central 48VDC will keep the lights on, your fan running and your secturity system functional whether it's for your home or business. This system is the same as our 4,400-watt Power Central Emergency backup system, but it has a different enclosure intended for outdoor use. 

Ready to Plug In
Four Star Solar assembles, wires and tests American-made inverters, metal housing and batteries to make up the WSS 4,400 Outdoor Power Central. It keeps your batteries charged by being plugged into a regular electrical outlet. When a blackout happens, the inverter instantly starts powering critical loads from the batteries until the power comes back on. It will then automatically re-charge its batteries and go into a standby mode. Housed in a locking Outdoor Midnite e-panel, it comes with an easy-to-use monitoring system so you can check your power supply anytime of day. See below for a complete list of parts and call us if you need more information. 

Get 30% Federal Tax Credit When You Add Solar Panels
This system could also be charged by solar panels or a generator. Adding solar panels to this system would qualify you for a 30% Federal Tax Credit. Wholesale Solar offers Solar Panel Add-on Options for this system. AC coupling for gridtie installations may also be an option for you. Be sure to ask a Sales Tech for more information. Back to Top
