The Victron Energy BlueSolar charge controller is an ultra fast Maximum Power Point Tracking (MPPT) solar charger with an outstanding conversion efficiency and is suitable for a wide range of battery and PV voltages.
The solar charger can charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to the battery voltage and will charge the battery with a current up to its rated current.
The product name of the solar charger incorporates the maximum PV voltage and the maximum battery charge current.
For example: A 150/70 model has a maximum PV voltage of 150V and can charge the battery with a maximum of 70A.
The table below indicates the maximum PV voltage and maximum battery charge current of the solar chargers that are covered by this manual:
Solar charger model | Maximum PV voltage | Maximum battery charge current | Suitable battery voltages |
|---|---|---|---|
MPPT 150/70 | 150V | 70A | 12, 24, 36 and 48V |
MPPT 150/85* | 150V | 85A | 12, 24, 36 and 48V |
MPPT 150/100* | 150V | 100A | 12, 24, 36 and 48V |
MPPT 250/70 | 250V | 70A | 12, 24, 36 and 48V |
MPPT 250/85 | 250V | 85A | 12, 24, 36 and 48V |
MPPT 250/100 | 250V | 100A | 12, 24, 36 and 48V |
*Please also see the notice for MPPT 150/85 and 150/100 in the technical specifications chapter.
The solar charger is available in two different models, namely:
The TR version - The PV terminals are screw terminals
The MC4 version - The PV terminals are MC4 terminals
The 70A MC4 model has 2 MC4 male and female connector pairs.
The 85A and 100A MC4 models have 3 MC4 male and female connector pairs.
