The Xantrex PROwatt SW 1000, MPN 806-1210, is a true sine wave inverter that converts 12-volt DC battery power to 120-volt-class AC for RVs, work and heavy-duty trucks, specialty vehicles and boats. Xantrex rates it at 900 watts continuous and 2000 watts surge. The 1000 in the model name is not the continuous rating, so plan your sustained loads around 900 watts. True sine wave output helps when you power electronics, chargers and appliances that do not run properly on modified sine wave. The SW 1000 is a standalone inverter. It does not charge batteries.

AC loads plug into dual GFCI receptacles, and a single Type A USB port supplies 5 V at 500 mA. The digital display shows DC voltage, AC output power and error codes. Input range is 10.5 to 15.5 volts DC. Output is 104 to 127 volts AC at 60 Hz ±0.5 Hz, with 90% optimum efficiency and under 0.6 amps of no-load draw. The store listing gives a low-voltage alarm at 11.0 V DC and shutdown at 10.5 V DC, with 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 89 × 220 × 339 mm (3.5 × 8.7 × 13.4 inches as listed by Xantrex) and weighs 7.2 pounds.

The DC side connects to heavy-duty battery terminals, and Xantrex recommends a 150 A DC fuse. Take DC cable size from the owner's guide for your cable length. To control the inverter from the dash or tie it to the vehicle ignition, add the PROwatt SW Remote Panel, part 808-9001. To feed hardwired AC circuits and switch between shore power and inverter output, add the 15 A Inline Transfer Relay, part 808-0915. Both are sold separately.

The PROwatt SW 1000 is a 12 V true sine wave inverter rated at 900 W continuous. Check these six points before you buy.

PROwatt SW 1000 or a Modified Sine Wave 1000 W Inverter?

Several 1000-class inverters sit side by side in this collection, but they deliver different power. The PROwatt SW 1000 provides 900 W continuous of true sine wave output, with dual GFCI receptacles, USB and a display, and an optional transfer relay and ignition-lockout remote. Modified sine wave models such as the Xantrex XPower 1000 list 1000 W continuous, but their waveform may not suit sensitive electronics, some chargers or variable-speed motor loads.

Choose the PROwatt SW 1000 when waveform quality matters and your simultaneous loads stay within 900 W. If you need more continuous true sine wave capacity, the PROwatt SW 2000 is rated at 1800 W continuous and needs a 250 A recommended DC fuse. Compare continuous rating, waveform and DC wiring requirements before choosing.

Frequently Asked Questions

What is the continuous rating of the Xantrex PROwatt SW 1000 (806-1210)?
Xantrex rates it at 900 watts continuous and 2000 watts surge. Size sustained loads to 900 watts.
Does the PROwatt SW 1000 produce pure sine wave power?
Yes. It produces true sine wave output at 104 to 127 volts AC, 60 Hz.
What battery voltage does it use?
It is a 12-volt inverter that accepts 10.5 to 15.5 volts DC.
Which outlets are on the inverter?
Dual GFCI AC receptacles and one Type A USB port rated 5 V, 500 mA.
Can I connect it to my RV's AC distribution panel?
The inverter's AC output is at its receptacles. The optional 15 A Inline Transfer Relay, part 808-0915, provides a hardwired AC connection and switches between shore power and inverter output.
Can the inverter turn off with the vehicle ignition?
Yes, with the optional PROwatt SW Remote Panel, part 808-9001. It shuts down the inverter output when the ignition or a 12 V DC enable signal is off.
What DC fuse is recommended?
Xantrex recommends a 150 A DC fuse. Use the owner's guide to size the DC cables for your run length.
Does the PROwatt SW 1000 include a battery charger?
No. It is a standalone inverter. Battery charging requires a separate charger or charging system.
