What happens when my RV Air conditioner starts?
1. Standard rooftop air conditioners use about 1500 to 1800 Watts while in a cooling cycle. That is approximately 12 to 15 Amps with a 120 Volt power source. Many portable generators can run this A/C; however, the actual problem is the STARTING CYCLE!
2. When an air conditioner starts, the compressor and the fan motor come ON together. Both motors draw about 12 to 15 Amps. However,
The Amp draw for both motors is about 5 to 8 times higher. The power surge lasts just a second or two, still - it's enough to stall the generator and trip the overload!
Instead of reducing the power draw electronically, we invented the Easy RV Starter™
No question, we need to reduce the power surge when the air conditioner starts.
There are some expensive electronic ways to reduce the power surge when the air conditioner starts, but we invented an easy and affordable solution for this problem - the RV-AC-Starter™.
That smart device delays the start of the fan motor for a few seconds; this way the compressor has time to reach full speed.
A short time later, the fan motor starts up too; but now the power-draw got reduced by some 50%.
As an additional benefit, the evaporator coil has time to get a bit colder before the blower fan starts!
CAUTION - Do Not play with the Thermostat!
Don't short-cycle your A/C, allow two or three minutes between starting of the A/C! The compressor increase the refrigerant pressure up to 350 PSI on the high side!
It takes time to equalize the pressure within the A/C system before the next startup.
Allow at least 2 minutes before starting up your A/C again to prevent damage to the compressor.
