Victron SmartSolar MPPT 75/15 Solar Charge Controller

What is a solar charge controller?

A charging device which converts the energy which your panels are producing to a stable charging voltage and current that your batteries can accept easily.

Nominal Power & Peak Efficiency

220 watts, 98% efficiency

Rated charge current

15 amps

Optimized for Solar Energy

Compatible with any solar panel. For higher efficiency we recommend using with a battery and a solar charge controller.

How does this fit into my off-grid, home power system?

This controls the charging of your batteries with solar panels and greatly increases performance. To use the energy you will an inverter. Inverters make it easy to use energy available from your batteries in the form of an AC wall plug.

MPPT: Ultra Fast Maximum Power Point Tracking

By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

Intelligent Load Output

The intelligent Load output function prevents damage caused by running batteries ‘flat’. You can configure the voltage at which SmartSolar disconnects a load – thereby preventing excessive drain on your batteries. And here’s the clever bit: SmartSolar will attempt a 100% recharge every day. If it can’t – during periods of poor weather – it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains the health, and extends the life of your battery.

Remote Monitoring and Control

Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. For remote installations – even when there is no internet connection or phone signal nearby – you may be able to monitor your MPPT by Bluetooth-pairing with a LoRaWAN (long-range wide area network) device, available optionally.
