Automatic battery voltage recognition
The controllers will automatically adjust to a 12V, 24V or a 48V system. A
computer or a smartphone is required to set the controller to 36V.
Adaptive three step charging
The BlueSolar MPPT Charge Controller is configured for a three step
charging process: Bulk – Absorption – Float.
A regular equalization charge can also be programmed: see section 3.8 of
this manual.
Bulk stage
During this stage the controller delivers as much charge current as possible
to rapidly recharge the batteries.
Absorption stage
When the battery voltage reaches the absorption voltage setting, the
controller switches to constant voltage mode.
When only shallow discharges occur the absorption time is kept short in
order to prevent overcharging of the battery. After a deep discharge the
absorption time is automatically increased to make sure that the battery is
completely recharged. Additionally, the absorption period is also ended when
the charge current decreases to less than 2A.
Float stage
During this stage, float voltage is applied to the battery to maintain it in a fully
charged state.
Connectivity
See section 3.3 of this manual.
