Xantrex SW4548E Grid Tie Inverter/Charger


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.


• Available in 3000 and 4500 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 1 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

Expandable and Flexible

• 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).
