Do you have START-UP problems with the Air Conditioner
and a Generator on your RV Camper?
The Generator stalls and trips the Overload
when the Air conditioner is starting...

Ever tried to start your A/C on a hot day with a generator that, theoretically, should run your A/C? The generator struggles and goes into overload because it cannot supply the starting current required to start the compressor and the fan motor. Of course, you can try to find help on the Internet…RV-forums and the Internet are filled with solutions..... often written by folks with not much of experience!
Here are a few facts:
1. RV Air Conditioners with 13’500 / 15'000 BTU will use about 1500 / 1800 Watt in cooling mode. This is equal to about 15 Amps on a 120 Volt power- supply. Even smaller portable generators are capable to run this A/C, but the real problem is the START!
The installation of our SUPER BOOST Hard Start might solve this problem, but in some cases, there are a few more tweaks required. Please read below.
2. Every time an A/C starts, both the compressor and fan motor are energized together. The two motors normally consume about 12 to 15 running Amps while operating in a cooling cycle, however, the Amp draw at the starting cycle is about 5 times higher. Even though this power surge lasts just a few seconds, it is enough to stall the generator and trip the overload!
Here is a simple solution: Use our RV AC Starter! A smart time delay circuit (Pat.pending) delays the fan-motor for a few seconds, giving the compressor enough time to start up and run with full speed before the fan motor starts. As an additional advantage, the evaporator coil has a bit time to cool down before the room blower starts.
The installation of the RV A/C Starter Kit is very simple - all parts are already installed and wired together on a aluminum plate. Simply disconnect a wire and attach it to the starter kit, then attach the free wire from the starter kit to the now empty place where the other wire used to be. (Don't worry, easy to follow instructions are included).
Use the included nylon ties to attach the starter kit to an existing capacitor or the cabinet wall or use the included self tapping screws to attach the starter to a wall.
