I recently purchased and installed the Cummins/Onan EC-30W AutoStart to my Onan QD 7500 generator. It was really easy to install. I also purchased the wiring harness pigtail which really made the job simple. I had to get down under the coach at the rear of the generator to attach one wire and I had to make a decision as to where I wanted to mount the controller. Those were the two most difficult tasks of the installation.
The setup was a snap. After setup I simulated a campground power outage. I was plugged into shore power and had an air conditioner running. I created a temperature set point on the EC-30W that was cooler than the ambient temperature and set the EC-30W to “Auto”. The generator will not start if shore power is detected so I went into my garage and flipped the breaker for the shore power to Off. Within about a minute the generator started up and the air conditioner soon followed. The system has several other nice features but sensing the loss of the shore power and starting the air conditioning units were our main concern.

Prior to installing the EC-30W we were concerned about our pets staying comfortable in the event of a power outage at the campground if we were not at the site. Needless to say, we are not concerned any more. This is really a sweet system.
