Summary

3,000 W with transfer switch, No charger

What it is: a 3,000 W, 12 V pure sine wave inverter that hands loads to shore or generator power automatically
The trade-off: transfer switching and a good efficiency rating, but no battery charging and options sold separately
Not checked: Rich Solar publishes no no-load draw while inverting
Look elsewhere for: an inverter-charger that also recharges the battery from shore power

Strengths

Automatic switching to shore power
Strong peak efficiency rating
Search mode trims standby use
Selectable output voltage and frequency
Ignition control for vehicle installs
Wide operating temperature range

Description

The Rich Solar NOVA SWITCH 3K (model RS-V3P12TS, sold as the NOVA 3K12) is a 12 V pure sine wave inverter rated 3,000 W continuous with a 6,000 W surge for 5 seconds.

It has a built-in automatic transfer switch with a 30 A relay that moves loads between shore or generator power and the battery in under 20 ms, in Normal or Fast mode. Its manual states it is an inverter only and is not intended for charging batteries.

Output is selectable at 108, 110 or 120 V AC and 50 or 60 Hz, under 5 percent total harmonic distortion, with a 91 percent peak efficiency and above 85 percent at full load per the manual.

It runs from the low-voltage cut-off to 18.0 V DC, draws 288 A at full load, and its low-voltage shutdown is adjustable from 10.5 to 12.8 V. AC input is 120 V at 80 to 140 V for full power.

It has an LCD with status LEDs, a load search mode that wakes for loads above 25 W, an ignition (ACC) input, a remote port, and RS232 and RS485 communication. AC wiring is hardwired through terminal blocks; Rich Solar's manual lists a GFCI kit and an LCD remote panel with a 25 ft cable as options sold separately.

It measures 15.4 x 12.0 x 4.1 in, weighs 17.6 lb and is rated from -40 to 160 °F. The box holds the inverter, the owner's guide with extra safety labels and a pre-installed DC ground lug. Rich Solar lists it as certified to UL 458 and FCC Part 15; its warranty page gives pure sine wave inverters 2 years, prorated.
