Using A Generator As Source Power
The Truecharge+ can be run from a regular power source or from an
alternate power source such as a generator. Refer to
for AC input draw to determine the size of generator you
need.
Many generators provide output voltage that is modified sine wave
(MSW) rather than the true sine wave (TSW) that your utility provides.
Xantrex does not recommend the use of Truecharge+ with MSW
generators due to increased heating of the charger.
Indicator Light Activity On The Front Panel
Indicator light activity shows what is happening during the charging
process and is also helpful in troubleshooting. Refer to

for more information about
interpreting indicator lights.
During the charging process, indicator lights are interpreted as follows:
