MPPT solar charger manual

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 75/15 model has a maximum PV voltage of 75V and can charge the battery with a maximum of 15A.

The table below indicates the maximum PV voltage and maximum battery charge current of the solar chargers that are covered by this manual:
