* Two banks of batteries in parallel. ** This is a combination of chargers in series parallel in order to increase the current rating, the voltages stay the same. ***RPM default settings, custom settings are available from the factory on special order, or field settable by a trained technician. ˇ Performance is based on battery power only - Run time can be continuous with Generator.
