SOLAR REGULATOR (Victron BS MPPT 100/50) 50A,12/24V,max 100V


A solar regulator connects the output of photovoltaic (PV) solar panels to a battery system. It adapts the voltage-current levels at the input to the battery voltage, thus protecting the battery from overloading. The built-in maximum power tracker (MPPT) ensures that the maximum solar power available is used to charge the battery.

This is a BlueSolar (BS) solar regulator, this model of regulators does not have a built-in Bluetooth capability.

Per piece.


The‌ solar regulator fits with strings of solar panels up to 100V (Voc) and charge currents up to 50 A. To ensure the MPPT can work with the string of solar panels the Victron MPPT Calculator tool ( must be used.

The regulator can be used in systems with battery voltages of 12V or 24V and an ‘Auto Select'- function automatically determines the right system voltage.

The MPPT Solar charger comes with VE.Direct interface in all versions. Together with an VE.Direct adaptor cable this makes it possible to configure the device. And it allows to connect the Solar charger with other Victron devices, like GX-controllers to integrate it into more sophisticated systems.


The basic function of a solar regulator is to control the input voltage and current from the PV solar panels in a way that batteries can be charged with their correct voltage. So it keeps batteries from overcharging.

Additionally, the MPPT converter allows to regulate the input voltage at a level where PV solar panels produce the maximum power. This so-called Maximum Power Point (MPP) is adjusted dynamically according to instant solar radiation.

A wired communication interface (VE.Direct) is available in all chargers. Via this interface the configuration of the device can be done. Additionally the charger can be connected with the Internet and the Victron Portal. And it can be connected to other Victron equipment to built up more sophisticated energy storage/distribution systems.
