This soft start keeps your AC, watermakers, pumps, and more running smoothly, even on generator or limited power. Avoid tripped breakers and protect your system with gentle starts wherever your adventure or work takes you.
A soft start device reduces the initial inrush current when an AC compressor kicks on. Instead of that harsh power spike that can trip breakers or overload generators, the soft start gradually ramps up the compressor's motor, making it easier to start an AC unit on limited power sources (like small generators, shore power, or inverters).
Not only will this device reduce your startup power demand by up to 70 percent, it's going to make your AC startup quieter, and reduce wear on the compressor. Plus, you get to skip the complicated installation and wiring. Just plug ActiveStart into your RV or boat's power source or generator, and you're ready to run your AC in less than a minute. With the included dogbone and ground-neutral plug, you can connect at the campground, marina, or to your generator for safe, reliable power anywhere.
When summer heat hits hard, two air conditioners make all the difference. Designed for 50-amp RVs and boats, ActiveStart can start and run two air conditioners at the same time. Redundancy means there are two independent circuits inside the device. Each circuit handles one leg of your 50-amp power cord. If one circuit fails, the other keeps working so you don't lose all your power or cooling.
ActiveStart isn't just for keeping your RV or boat cool. By reducing startup spikes and making power delivery smoother, this soft start protects and improves performance for water maker systems, marine AC and refrigeration, pool and irrigation pumps, HVAC and industrial compressors, and off-grid or generator-based electrical setups. When high-draw equipment starts up gently, you avoid tripped breakers and keep your whole system running reliably—even on limited power.
The Bluetooth mobile app makes it easy to check real-time voltage and status for your power system. View and adjust settings right from your phone for added control and peace of mind.
Alternate Instructions
The instructions should be more in detail for the settings. I had to call Thomas the technician to help me with the set up, once he walked me the the procedure it worked well, I was able to rum both of 15000 but ac and the refrigerator wit a 4650 watt portable inverter generator ran at 75 percent capacity. I would highly recommend so far, but I haven't ran it for a long period of time. I will be able to let you know more about it about the middle of August.
