Victron Energy SmartSolar MPPT 75/10 Solar Charge Controller 75V 10A

The Victron Energy SmartSolar MPPT 75/10 Solar Charge Controller 75V 10A is a compact MPPT regulator designed to optimize charging of 12V and 24V battery systems from photovoltaic panels. With a maximum PV input voltage of 75V and a rated charge current of 10A, it applies Maximum Power Point Tracking (MPPT) to extract the highest possible power from the solar array and deliver controlled charging to the battery. Its small footprint and low weight make it suitable for installations in confined spaces where efficient battery maintenance is required.

Advantages

The controller uses MPPT technology to improve energy harvest compared with simpler PWM regulators, especially under variable irradiance and temperature conditions. A maximum input voltage of 75V allows the use of higher-voltage PV arrays and longer cable runs. The 10A charge rating is appropriate for small to medium domestic or mobile systems, while the compact physical dimensions simplify mounting and integration. Built-in charge regulation helps prolong battery life by preventing overcharge and supporting proper charge stages.

How to use

Install the SmartSolar MPPT controller on a ventilated, non-corrosive surface, following local electrical codes. Connect the battery first, then the PV array, observing correct polarity. The controller will automatically detect 12V or 24V battery systems and begin MPPT charging. Configure charging parameters if required using compatible Victron interface tools or settings, and monitor battery voltage and charging current to ensure correct operation.

Recommendations

Place the controller where it receives adequate ventilation and avoid mounting near heat sources. Use appropriate cable sizes and fuses between panels, controller and battery to minimize voltage drop and ensure safety. For reliable long-term performance, match PV array open-circuit voltage and power to the controller’s 75V input limit and 10A charge capacity, and consult battery manufacturer guidelines for recommended charge voltages.
