2. Introduction

The Victron Energy SmartSolar 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 150/70 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
MPPT 150/70 150V
MPPT 150/85 150V
MPPT 150/100 150V
MPPT 250/70 250V
MPPT 250/85 250V
MPPT 250/100 250V

2.2. TR or MC4 model

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.
