Buying Guide
Key considerations help buyers match a soft start kit to their RV setup and travel style. Critical factors include compatibility, power source, installation complexity, noise reduction, and durability.
- Compatibility: Check BTU rating and whether the kit supports your roof-mounted AC unit. Some kits are designed for up to 15,000 BTU, others handle 20,000 BTU or more. If you run two ACs, consider a kit that supports dual units or pair multiple kits as needed.
- Power Source: Determine your typical power hookup (20A, 30A, or generator size). Choose a kit that can operate within that limit without tripping breakers.
- Installation: Some products include mounting hardware and connectors; others require more manual setup. If you’re not comfortable with wiring, prefer kits advertised as easy to install or with included installation supplies.
- Noise and Comfort: A notable benefit is quieter compressor start. Consider user reviews or product claims about reduced thumping and vibration for a more comfortable campsite.
- Durability and Warranty: Waterproofing and build quality matter for outdoor mounting. Look for IP-rated housings or waterproof claims and check warranty terms.
- Cost vs. Benefit: While most kits aim to save generator fuel and prevent breaker trips, evaluate whether the initial cost aligns with your camping frequency and power constraints.
In practice, RV owners with limited shore power appreciate soft start kits that enable running a single AC from a 20A to 30A connection or a modest generator, while still having power left for essential appliances. For larger RVs with dual AC units or demanding electronics, consider a higher-capacity setup or pairing two suitable kits, ensuring proper electrical safety and adherence to campground rules.
