Four Charging Stages
The Rover MPPT charge
efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge,
and Equalization.
Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar
power to recharge the battery and is equivalent to constant current. In this stage the battery
voltage has not yet reached
constant current mode, delivering its maximum current to the batteries (MPPT Charging)
Constant Charging:
will start to operate in constant charging mode, where it is no longer MPPT charging. The current
will drop gradually.
constantly in a full charge process to avoid too much gas precipitation or overheating of the
battery
Boost Charge:
can adjust the constant time and preset value of boost per their demand
Float Charge: After the constant voltage stage, the controller will reduce the battery voltage
to a float voltage set point. Once the battery is fully charged, there will be no more chemical
reactions and all the charge current would turn into heat or gas. Because of this,
controller has a 4-stage
