SoftStartRV Soft Start Kit for RV Air Conditioner
The SoftStartRV kit offers a compact, efficient solution to reduce the startup load of RV air conditioners by about 65-70%, allowing smaller generators (as low as 2200W) to power systems up to 36,000 BTUs including two rooftop ACs on a 30-amp supply.
Its waterproof design and noise reduction technology minimize compressor vibrations and starting thumps, leading to quieter operation. This kit helps RV users maximize the utility of existing power sources, ensuring smooth AC start-ups without overloading circuits or causing interruptions. It’s a practical choice for motorhomes, trailers, and campers.
briidea Soft Starter for RV Air Conditioner
The briidea soft starter allows you to start a 15,000 BTU RV air conditioner using only a 2200W generator. It efficiently reduces the AC startup current by about 65-70%, which helps prevent breaker trips and generator overloads.
This technology lets you power multiple appliances simultaneously, such as refrigerators, heaters, and microwaves, without needing larger generators. Installation allows operation of two air conditioners on a 30-amp hookup with two soft starters. Additionally, its noise reduction feature contributes to a more peaceful environment inside your RV during travel.
Buying Guide: Key Factors When Choosing a Solar Generator for RV Air Conditioners
Selecting the ideal solar generator or soft start kit for your RV air conditioner depends on multiple considerations to ensure compatibility, efficiency, and convenience during your travels.
Power Capacity and Output
- Match Generator Wattage to AC Requirements: RV air conditioners generally require significant startup wattage to handle compressor surges, often much higher than running wattage. Ensure your solar generator can deliver peak and continuous power to prevent interruptions.
- Expandability: Some models, like the EF ECOFLOW DELTA Pro, offer battery expansion and generator add-ons for increased capacity, beneficial for longer trips or additional appliances.
Soft Start Technology
- Reduces Startup Surge: Soft starters lower peak startup power consumption by 65-75%, enabling smaller solar generators or inverters to efficiently run your AC unit and other devices.
- Compatibility: Ensure the soft starter supports your specific AC type, such as single or two-stage compressors and heat pumps. Waterproof designs add durability for RV environments.
Battery Type and Runtime
- Battery Chemistry: Lithium ferro phosphate (LiFePO4) batteries offer longer lifespans and safer charging cycles compared to traditional lithium-ion batteries.
- Run Time Considerations: Evaluate the watt-hour rating (Wh) of the generator battery to estimate how long it can power your air conditioner, factoring in cooling demands and ambient temperature.
Charging Options and Portability
- Solar Panel Compatibility: Generators with included or compatible solar panels allow recharging off-grid to extend usability.
- Fast Charging: Quick recharge times via AC or solar optimize downtime.
- Portability: Look for compact, lightweight designs with handles or wheels if frequent transport is expected.
Additional Features
- Noise Reduction: Soft starters reducing compressor noise improve onboard comfort.
- Multiple Outputs: Consider units with various AC and USB outlets to power other RV electronics simultaneously.
- App Control and Monitoring: Real-time energy use feedback and remote control enhance user experience.
Assessing these factors in line with your RV air conditioner’s BTU rating, power source limitations, and travel habits will guide you toward the best solar generator and soft start combination to maintain cool comfort on the road.
