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:

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 60A MC4 model has 2 MC4 male and female connector pairs.
The 70A MC4 model has 2 MC4 male and female connector pairs.
