The SW Inverter/Charger is our most popular off-grid power solution. Available in 24- and 48-volt models, it provides utility-grade output power and offers high surge capacity to run most household appliances. The SW offers many programmable features including automatic generator start and stop, and automatic load sensing. Its built-in, fully automatic, three-stage battery charger is designed to bring maximum charge to batteries, while using minimum generator run time and fuel.
• Parallel stacking capability for more power at the same voltage (optional equipment is required)
• Three phase configurations available in a Power Module System for industrial quality power in remote locations (optional equipment is required; only available on 48-volt models).
