Using A Generator As Source Power
The Truecharge2 Battery Charger can be run from a regular AC power source or from an alternate power source such as a generator. Refer to “AC Input Specifications” on page 54 for AC input current draw to determine the size of generator you need. Many generators provide output voltage that is modified sine wave or modified square wave (MSW) rather than the true sine wave (TSW) that your utility provides.
If a generator needs to run on full load capacity to supply charging current to the battery via the battery charger, its output frequency and amplitude may become unstable. This scenario can cause the battery charger to shutdown. Using the current limiting feature1 from the remote panel can help avoid this scenario.
The Truecharge2 Battery Charger may be used with MSW generators but its lifetime may be reduced somewhat depending on the severity of any peak voltage overshoots, and the severity of waveshape rise times.
