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 100/30 model has a maximum PV voltage of 100V and can charge the battery with a maximum of 30A.
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 100/30 | 100V | 30A | 12 and 24V |
MPPT 100/50 | 100V | 50A | 12 and 24V |
