When the AC power charging process starts, the charging current will each peak in around 3 seconds, the
charger may overload the AC input generator and drop its output frequency, making inverter switch to
battery mode.
It is suggested to gradually put charging load on the generator by switching the charging switch from
minimum to maximum, and give the generator enough time to spin up.
Caution:
To guarantee the best performance of the AC charger when the AC input is from a
generator, the standby generator should be rated at least 150% higher capacity than
the inverter.
Warning! Operation with an under-rated generator or generator with unqualified
wave form may cause premature failure which is not under warranty.
Battery Equalization
The equalization function has been added into the M series inverter charge controller. It reverses the buildup
of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom
of the battery than at the top. Equalization also helps to remove sulfate crystals that might have built up on
the plates. If left unchecked, this condition, called sulfation, and will reduce the overall capacity of the
battery. Therefore, it’s recommended to equalize battery periodically.
How to Apply Equalization Function
You must enable battery equalization function in monitoring LCD setting program 43 first. Then, you may
apply this function in device by either one of following methods:
1. Setting equalization interval in program 47.
2. Active equalization immediately in program 48.
When to Equalize
In float stage, when the equalization interval setting (battery equalization cycle) has arrived, or equalization
is active immediately, the controller will start to enter the Equalize stage.
