Product Information
About
CUTS STARTUP AMPS 65%-70% — RUN ON SMALL GENERATOR, INVERTER & SOLAR：Our RV AC soft start kit reduces compressor surge current by 65%-70%, so a small generator, RV inverter, or off-grid solar setup can easily start your 1.75-3 Ton rooftop air conditioner without overload, tripped breakers, or shutdown. Perfect for boondocking and dry camping where shore power isn't available.
WIDE 115-240V / 50-60Hz COMPATIBILITY — UP TO 3 TON：Works with 115V-240V, 50-60Hz rooftop RV AC units up to 3 Ton (36,000 BTU, including 15,000 BTU models) on motorhomes, travel trailers and campers. Run one A/C on a 15A or 20A hookup, or two units simultaneously on 30A shore power (two starters required for dual A/C setups).
BUILT-IN CAPACITOR & CONTACTOR — NO EXTRA PARTS TO BUY：Start and run capacitors are preinstalled inside the soft starter, and no external contactor is required. Fewer components means fewer failure points, cleaner wiring, and a faster installation — no last-minute runs to the hardware store mid-project.
SMOOTH, QUIET STARTUP PROTECTS YOUR COMPRESSOR：Gradual voltage ramp eliminates the harsh thump and loud bang on startup, reducing mechanical wear and shielding your A/C from damage caused by unstable voltage and overload surges. The sealed waterproof housing stands up to the heat, dust and vibration of the rooftop environment.
EASY DIY INSTALL + 3 LED INDICATORS + 24H SUPPORT：Complete kit includes color-coded wires, insulated terminals, butt splices and mounting screws, with a wiring schematic printed right on the housing. Three LED indicators (Run / Start / Self-test) show real-time status for quick troubleshooting. Most owners finish in under an hour with basic tools — and if you get stuck, our team responds within 24 hours.
