SoftStartRV is the best RV A/C soft starter kit for these situations. SoftStartRV is an embedded design air-conditioner soft start controller for single phase A/C power systems. It regulates the startup voltage of the compressor and/or motor intelligently to easily reduce the inrush and surge current while starting up. As a result, much less power is needed from on-site the A/C power supply system – while enabling full startup torque for compressors and motors. SoftStartRV effectively limits the inrush current, and improves the stability of the power supply while reducing transient voltage drops that may affect or break down other loads. This eliminates the need for excessive power supply, which results in: - Reduced equipment costs, - Efficiencies in power supply capacity, charge meter, circuit breaker, and power wireline capacity. Ultimately, it extends the service life of the motor or compressor. Not only does the SoftStartRV ease strain on the power source, but it’s also less stressful for the compressor since it starts more gently. Additionally, it provides valuable protection by shutting down the compressor if the power source - or the connection to the compressor - is briefly interrupted, then it re-attempts a soft start after a three-minute delay. SoftStartRV is a compact, lightweight cost-effective soft start controller with fireproof housing, and sealed by resin. As a result, it can withstand extreme weather, and survive in harsh environments (such as installation within outdoor rooftop air conditioner units). This makes SoftStartRV a cost-effective RV air conditioner soft start kit solution with high reliability and longevity.
