Description
RV Air Conditioner Soft Start Kit — 364 Compatible
Most RV air conditioners draw 50-70 amps on startup — enough to trip a 30A breaker or stall a portable generator. This soft start kit reduces inrush current by up to 70%, letting you run your A/C on a small 2000W generator, 30A shore power, or even a battery/inverter setup. Compatible with popular 364 soft start systems. Perfect for boondocking, campgrounds with limited power, or saving your generator from hard starts.
Key Features
-
70% Startup Surge Reduction — Ramps the compressor gently instead of slamming it with full current. Your generator won't stall, your breaker won't trip.
-
Runs on 2000W Generator — A standard 13,500 BTU RV A/C normally needs 3000W+ to start. With this kit, a 2000W generator is sufficient.
-
364 System Compatible — Plug-and-play replacement or upgrade for 364-type soft start systems. Same wiring, same footprint.
-
Protects Your A/C Compressor — Soft starting reduces mechanical shock on the compressor, extending its service life.
-
DIY Friendly — Includes wiring diagram and mounting hardware. Basic electrical knowledge required. 30-60 minute install.
-
Universal Fit — Works with most rooftop RV air conditioners: Dometic, Coleman, Advent, Atwood, Furrion, and others.

Why Choose iFJF?
Without a soft start, every A/C cycle puts enormous stress on your generator, breaker panel, and compressor. The result: tripped breakers on hot days, generator overloads, and premature compressor failure. Our soft start kit gives you freedom to camp anywhere — national park with 30A only, boondocking with a small generator, or driveway camping on a 15A household outlet.
Frequently Asked Questions
Q: Will this work with my RV's A/C unit?
A: Compatible with most single-compressor rooftop RV A/C units up to 16,000 BTU. Check the compatibility table above. If your unit isn't listed, contact us with your make/model for confirmation.
Q: Can I really run my A/C on a 2000W generator?
A: Yes. A 13,500 BTU A/C normally needs 2800-3000W to start. The soft start drops startup surge by 60-70%, making a 2000W generator sufficient. Still need headroom for other loads like microwave.
Q: Is this hard to install?
A: Basic electrical skills required. Wiring into compressor circuit on the rooftop unit. Clear wiring diagram and hardware included. Typical install: 30-60 minutes. Professional install recommended if uncomfortable with 120V AC.
Q: Will this damage my A/C compressor?
A: No — it protects the compressor. Soft starting reduces mechanical shock and current inrush, actually extending compressor life. Same technology used in residential HVAC.
Q: Does this work with inverter generators?
A: Yes, inverter generators benefit the most. Their eco-mode can't handle hard-start surges. The soft start solves this perfectly.
Q: Do I need one per A/C unit?
A: Yes, each rooftop A/C needs its own soft start kit. Dual A/C setups require 2 kits.
