DR, GT, SW, SW Plus
DR Inverter/Charger

Provides dependable modified sine wave power for businesses, homes and workshops. Available in 1500, 2400 or 3600 watt models, it can power most common electrical appliances such as lights, televisions, cash registers, refrigerators, washing machines, computers, and power tools. The DR’s high surge capacity gives it the ability to start difficult motor loads. Once set up, all functions of the inverter/charger are fully automatic.

SW 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 as well as 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.
Grid Tie: Using the Xantrex Grid Tie Interface (GTI), the SW converts energy from multiple renewable energy sources, such as solar, wind, and microhydro, into AC power, selling power you don't use back to the utility. Software/hardware revision 4.2 or higher is required to connect the SW4024, SW4048, or SW5548 to the GTI.
- 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 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)
SW Plus 2500, 4000 and 5500

Designed to provide homes with a completely independent power supply, SW Plus 2500, 4000 and 5500 Inverter/Chargers combine an inverter, battery charger and dual transfer switch in one package.
Available in 24- and 48-volt versions, the SW Plus offers continuous power output of 2.5, 4.0 and 5.5 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. Details about the SW Plus are included in the latest edition of Renewable Power News. Information is also available in this FAQ.
The SW Plus can also be used as part of a backup power system to automatically provide AC power when utility power fails. For supplementary power, the inverter/charger can be combined with the optional Generator Start Module (GSM) to automatically start and stop a generator, based on user needs. To save on utility bills, the SW Plus can also be programmed to switch to battery power from utility power during peak-rate periods.
Product Features
- 2.5, 4.0 and 5.5 kVA continuous output of sine wave power (to 40º C)
- Huge surge (inrush current) capacity – up to four times rated output for starting large loads
- High capacity, multi-function battery charger provides accurate four stage re-charging and maintenance
- Smart Energy Management system controls utility and/or generator usage
- Non-volatile memory provides the SW Plus with the ability to save customized settings
- FCC Part B compliant means less potential interference with radio and telephone equipment
- Energy efficient with 95% peak efficiency and <20 watts of idle current (<2 watt in search mode)
