Charger
IMPORTANT:
Battery charger settings need to be correct for a given battery type. Always follow battery
manufacturer recommendations. Making incorrect settings, or leaving them at factory default
settings, may cause the batteries to be undercharged or overcharged.
The charge controller uses a “three-stage” battery charging cycle which utilizes multiple settings. This
menu controls the voltages and timers for the battery charger. See the charge controller Owner’s Manual
for an explanation of the three-stage cycle and a description of the individual stages.
