2. Introduction
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.
2.1. Battery voltage, PV voltage and current rating
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 150/45 model has a maximum PV voltage of 150V and can charge the battery with a maximum of 45A.
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 150/35 | 150V | 35A | 12, 24, 36 and 48V |
MPPT 150/45 | 150V | 45A | 12, 24, 36 and 48V |
