MPPT solar charger manual

2. Introduction

In this section:

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:
