1.8 Automatic battery voltage recognition
The MPPT 100/30 will automatically adjust itself to a 12V or a
24V system.
1.9 Adaptive three step charging
The BlueSolar MPPT Charge Controller is configured for a three
step charging process: Bulk – Absorption - Float.
1.9.1. Bulk stage
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
1.9.2. 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 2 A.
1.9.3. Float stage
During this stage, float voltage is applied to the battery to
maintain it in a fully charged state.
1.10 Connectivity
See section 3.8 of this manual
1.11 Remote on-off
The MPPT 100/30 can be controlled remotely by a VE.Direct non
inverting remote on-off cable (ASS030550300). An input HIGH
(Vi > 8V) will switch the controller on, and an input LOW (Vi < 2V,
or free floating) will switch the controller off.
Application example: on/off control by a VE.Bus BMS when
charging Li-ion batteries.
1.12 Real-time data display on Apple and Android
smartphones, tablets and other devices
VE.Direct to Buetooth Low
Energy (BLE) dongle
