Micro-Air EasyStart Soft Starter Installation into RV Rooftop Air Conditioner

Micro-Air EasyStart Soft Starter Installation into RV Rooftop Air Conditioner

The Micro-Air EasyStart reduced the start surge current of this Coleman Mach 13.5kBTU rooftop from 41.1A (measured, 54 LRA rated) to an astonishing 17.3A. This then allows the system to operate on a limited-current power source as small as 2000W, be it a generator or an inverter. All the details of the actual installation, comparison testing, and technical explanations are covered.
