The Xantrex PROwatt SW 600, MPN 806-1206, is a compact true sine wave inverter that converts 12-volt DC battery power to 120-volt-class AC for RVs, work trucks, heavy-duty trucks and boats. The model name says 600, but Xantrex rates it at 540 watts continuous and 1200 watts surge, so size your loads to 540 watts. True sine wave output suits loads that may not run properly on modified sine wave, including some variable-speed tools, electronics and appliances, within this unit's rating. The PROwatt SW 600 is a standalone inverter. It does not charge batteries.

AC power is delivered through dual GFCI receptacles, and a Type A USB port supplies 5 V at 500 mA. A built-in digital display shows DC voltage, AC output power and error codes. The unit accepts 10.5 to 15.5 volts DC and produces 104 to 127 volts AC at 60 Hz ±0.5 Hz. Optimum efficiency is listed at 90% and no-load draw at under 0.6 amps. The store listing gives a low-voltage alarm at 11.0 V DC and low-voltage shutdown at 10.5 V DC, plus overvoltage, overload, over-temperature and GFCI protection. Xantrex lists UL 458 with Marine Supplement 01 and CSA 107.1 safety approvals and FCC Part 15 Class A EMC. The housing measures 3.5 × 8.7 × 12.2 inches and weighs 6.5 pounds.

The DC connection is hardwired to heavy-duty battery terminals, and Xantrex recommends a 150 A DC fuse. Take the cable size for your run from the owner's guide. Two optional accessories extend the installation. The PROwatt SW Remote Panel (808-9001) adds on/off control with an ignition lockout that switches the inverter output off unless the ignition or a 12 V DC enable signal is present. The 15 A Inline Transfer Relay (808-0915) switches between shore power and inverter output and provides a hardwired AC connection. Neither accessory is included with the inverter.

Match the Inverter to the Battery System and Loads

The PROwatt SW 600 is a 12 V true sine wave inverter rated at 540 W continuous. Check these six points before you buy.

PROwatt SW 600, SW 1000 or SW 2000?

The three North American PROwatt SW models share 12 V DC input, true sine wave 120 V-class output, dual GFCI receptacles, a USB port and a digital display. They differ mainly in capacity. The SW 600 is rated at 540 W continuous and 1200 W surge, which suits electronics, chargers and modest appliances where a compact unit and lower DC current are priorities. The SW 1000 steps up to 900 W continuous and 2000 W surge with the same 150 A recommended fuse.

Choose by the total wattage of the loads you will run at the same time, not by the number in the model name. If your loads approach or exceed 540 W, move up to a larger model rather than relying on surge capacity. Do not confuse this inverter with the PROwatt SW International models, which produce 230 V AC for non-North American appliances and are listed separately in this collection.
