battery charging efficiency, and prolong battery life (VE.Direct
Bluetooth Smart dongle needed).
Alternatively, Bluetooth communication can be set up between a
BMV-712 battery monitor with battery temperature sensor and the
solar charge controller (VE.Direct Bluetooth Smart dongle
needed).

1.8 Automatic battery voltage recognition
The MPPT 150/35 will automatically adjust itself to a 12V, 24V or
a 48V system one time only. If a different system voltage is
required at a later stage, it must be changed manually, for
example with the Bluetooth app, see section 1.11.
1.9 Flexible charge algorithm
Fully programmable charge algorithm, and eight preprogrammed
algorithms, selectable with a rotary switch.
1.10 Adaptive three step charging
The BlueSolar MPPT Charge Controller is configured for a three
step charging process: Bulk – Absorption – Float.
1.10.1. Bulk
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
1.10.2. Absorption
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.
1.10.3. Float
During this stage, float voltage is applied to the battery to
maintain it in a fully charged state.
1.10.4. Equalization
See section 3.8
