SoftStartRV Soft Start for RV Air Conditioner
Best for: RV owners with small generators or 30-amp/15-amp hookups who want reliable cooling without loud starts. This model advertises a 40% smaller footprint to fit low-profile A/C units and claims 100% waterproof protection. It supports starting two A/Cs on 30-amp and one on a small generator, and can power up to 36,000 BTUs with a 2200W generator. It reduces compressor noise and vibrations, delivering quieter operation. Caution: verify compatibility with your specific A/C model and ensure proper mounting for water sealing.
Soft Start for RV Air Conditioners (Kedite)
Best for: DIY installers seeking clear guidance and a strong reduction in inrush current. Kedite promises up to 70% reduction, helping prevent breaker trips and generator strain. The kit emphasizes easy installation with straightforward instructions and ongoing support. Caution: real-world results depend on your existing electrical setup and generator size; ensure two-stage or compatible wiring is available if you run two A/Cs.
SpartanStart – Soft Start Kit for RV A/C
Best for: RVs with up to 20,000 BTU A/C units and users who want generator-friendly operation. SpartanStart emphasizes a generator anti-stall and preload feature, smooth switching among generator, inverter, or campsite power, and built-in motor reversal protection during outages. Caution: designed for specific power configurations; confirm compatibility with your inverter or generator before purchase.
Aoteda Soft Start for RV Air Conditioner
Best for: RVers who want broad compatibility and proven inrush reductions. Aoteda claims 65–70% reduction and supports use with 20A or 30A connections, including running two A/C units with two soft starters. Caution: for two A/Cs, both need their own soft starters and proper installation to avoid overloading circuits.
TURBRO RV AC Soft Start Kit
Best for: RVs needing a widely compatible soft start with a broad voltage range. TURBRO reduces starting currents by 60–75% for non-inverter RV ACs and supports up to 15,000 BTU units. It’s designed for running two A/Cs on a 30 A hookup with two soft starters. Caution: not all older models may benefit equally; verify generator compatibility and power supply stability.
SoftStartUp Plug & Play RV A/C Soft Start
Best for: RV owners who want a no-tools, no-wiring installation experience. The Plug & Play unit can run up to two A/Cs from a single power source, supporting 50A, 30A, and 20A. It reduces startup surge by about 50–60%, offering quieter starts and extended compressor life. Caution: ensure your power source supports the chosen configuration and that you don’t exceed your panel’s limits with other devices.
Buying Guide
What should I consider when choosing an RV AC soft start?
- Power source compatibility: Check your RV’s electrical hookup (20A, 30A, or 50A) and whether you plan to run one or two A/C units simultaneously.
- BTU range: Ensure the kit supports your A/C unit’s BTU rating and is suitable for the unit’s start-current requirements.
- Installation approach: Decide between plug-and-play (no wiring) versus hard-wired kits, which may require mounting and wiring in an electrical panel.
- Waterproofing and durability: For outdoor mounting, waterproof or weather-resistant models help protect electronics in the RV environment.
- Noise and comfort: Soft-start features reduce compressor noise at startup, contributing to a quieter camper experience.
- Generator and inverter compatibility: If you rely on a generator, verify that the soft start can handle startup surges without overloading the system.
Best practices for installation and use
- Follow the manufacturer’s wiring and mounting instructions precisely to ensure safety and effectiveness.
- Test with both A/C units off, then gradually load appliances to confirm stable power transitions.
- Use a properly rated surge protector and voltage monitoring to protect other devices in the RV.
- Consider having a professional assist with complex installations for dual-A/C setups.
How to compare options quickly
- Best for no-installation needs: SoftStartUp Plug & Play (NetworkRV).
- Best for two-A/C setups on limited power: TURBRO or SoftStartRV pair when using dual kits.
- Best for high BTU or generator-heavy use: SpartanStart or Aoteda for broader compatibility and robust performance.
FAQ
- Do RV soft start kits reduce power draw on all A/C units? Most kits reduce startup surge significantly, but results depend on unit make/model and electrical setup.
- Can I install these myself? Many are designed for DIY installation, especially plug-and-play models. Some kits require basic wiring and mounting.
- Will a soft start protect my generator? Yes, by reducing surge, it lowers the risk of overloading the generator during compressor startup.
- Can I run two A/C units with one soft start kit? Some kits permit dual A/C operation with appropriate configurations and multiple kits, but follow the manufacturer’s guidelines.
- Are these waterproof? Several models advertise waterproof or rugged construction suitable for RV environments.
- Will soft start affect efficiency? Soft starts can improve efficiency by reducing abrupt power spikes and extending compressor life, though exact gains vary.
