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 page 96 for an explanation of the
three-stage cycle and a description of the individual stages.
MPPT
The charge controller uses a maximum power point tracking (MPPT) algorithm which manipulates the
output of the PV array to harvest maximum wattage. Although this function is automatic, this menu
allows the user to adjust many of its parameters for special applications. See page 47, 48, and 100.
