DOES MY 12KW COME WITH A SMART CHARGER AND HOW DOES IT WORK?

Your 12kW unit comes with a Smart charger in the box, which includes an AC power cord as well as a cord to attach to the port in the control panel. It is designed to keep the battery charged during storage and avoid normal self-discharge from non-use. Keeping the generator battery fully powered will aid easy start during and after storage. Although the charger is a Smart Charger, we recommend that you do not keep it connected for long periods of time.
