Worry-Free Control of Your Power Systems
Starts and stops the generator as required to maintain battery health
Will only start the generator if shorepower is NOT present
Automatic generator turn on to meet air conditioning demands if coach gets too hot
Wireless - RV owners can install themselves (see how to install)
Introducing the newest RV power generation solution -- Energy Command™ AutoStart . The EC-30W is the first autostart system specifically designed for RV owners to install themselves. This provides worry-free control for most Cummins Onan diesel, gas, or LP generators. While high-end diesel RVs have added autostart as a factory option in recent years, most RVers who could use an autostart system on their existing RV don’t have one. Because the EC-30W is wireless, the average RV owner can install it on their own without paying for installation. At the same time, the EC-30W maintains several features that are unique to the Energy Command family. These unique features include:
- Detection of Shorepower so the EC-30W will only start the generator if shorepower is NOT present and batteries get low or the RV gets too hot. This allows the RVer to use the EC-30W as a back-up to shorepower in campgrounds with weak or intermittent power.
- An accelerometer to detect when the RV moves to prevent the EC-30W from accidentally starting the generator when the RV is placed inside an enclosed space.
- Battery backup to maintain settings in the EC-30W when power is removed. (Don't have to constantly reset the clock.)
Cummins Onan Energy Command 30W (EC-30W)
Cummins Onan EC-30W puts RV power in the palm of your hand.
Cummins Onan Energy Command 30W consists of a receiver that is wired to the generator and a hand-held transmitter that is used to automatically start and stop the generator as required to maintain battery health and temperature inside the RV.

How to install the EC-30W AutoStart (COMING SOON)
There are 2 modules to the system. The generator module is mounted in the generator compartment and plugs into the generator remote harness. This allows the unit to turn the generator on and off based on wireless signals from the remote module mounted inside the RV. The generator module includes the accelerometer to detect when the RV moves and shut off the auto function as a safety. It also connects to the B+ battery terminal on the generator to provide power to the unit and detect house battery voltage.
