Victron Smart Solar MPPT 75/15 (12/24V) Solar Charge Controller - SCC075015060R

MPPT stands for Maximum Power Point Tracking.

Solar panels produce power at a specific voltage and current combination where they generate the maximum possible energy. That point changes throughout the day depending on sunlight, temperature, and panel conditions.

An MPPT solar controller constantly adjusts the way it draws power from the panels so they stay at their most efficient operating point.

Simple explanation: it works like a smart gearbox for your solar system.

For example, your solar panel may be producing 18V, while your battery only needs around 13–14V to charge. Instead of wasting that extra voltage, an MPPT controller converts it into more charging current.

Example:
Solar panel output: 18V × 5A = 90W
Battery charging output: 14V × 6.4A ≈ 90W

That means you get more usable power into your battery instead of losing energy as heat. This is why MPPT controllers can often deliver 20–30% more usable power than basic PWM controllers.

1. It gets more power from your solar panels

Victron’s ultra-fast MPPT tracking constantly finds the optimal power point of your panels. This means:

• more energy harvested
• faster battery charging
• better performance in cloudy or low-light conditions

For caravans, off-grid systems, 4WDs and boats, that extra harvested power can make a noticeable difference every day.

2. It protects expensive batteries

Your batteries are one of the most valuable parts of your solar setup. The Victron SmartSolar controller manages a precise multi-stage charging process to help prevent:

• overcharging
• deep discharge
• premature battery wear

It is compatible with Lithium, AGM, Gel and Lead-Acid batteries, helping extend battery life and maintain reliable performance.

3. You can monitor everything on your phone

The SmartSolar range includes built-in Bluetooth. Using the VictronConnect app, you can check:

• solar production
• battery voltage
• charging current
• historical performance
• system warnings and settings

This gives you full visibility of your solar system and makes troubleshooting and optimisation much easier.

In simple terms, an MPPT controller is the brain of your solar system. It helps your panels produce the maximum possible energy while charging your batteries correctly and safely.

That is why buyers choose the Victron SmartSolar MPPT — it delivers more usable solar power, better battery protection, and smarter monitoring than many cheaper alternatives.

Smarter Solar Charging with Victron SmartSolar

A solar charge controller collects energy from your solar panels and safely stores it in your batteries. The Victron SmartSolar MPPT uses advanced technology to maximise the energy harvested from your panels and deliver it efficiently to your battery bank.

Using ultra-fast Maximum Power Point Tracking (MPPT), the controller constantly monitors the voltage and current produced by your solar panels and adjusts its operation to capture the maximum available power. This is especially noticeable when sunlight conditions change, such as during cloudy weather or early morning and late afternoon light.

By optimising charging and carefully managing battery voltage, SmartSolar helps maintain battery health and extend battery life.

Recharge Even Severely Depleted Batteries

The SmartSolar controller is designed to recover deeply discharged batteries. It can begin charging with battery voltages as low as 0 volts, provided the battery cells are not permanently sulphated or damaged.

Monitor and Control from Your Phone

With built-in Bluetooth, you can monitor and configure your SmartSolar controller directly from your smartphone using the VictronConnect app. View real-time data including solar power output, battery voltage, charging status and historical performance.

If your system is connected to the internet via a Victron GX device, you can also access your system remotely through the Victron Remote Management (VRM) Portal, allowing full monitoring and control from anywhere in the world.

For remote off-grid installations without internet access, monitoring can still be achieved using devices such as the Victron GlobalLink 520.

Intelligent Battery Protection

The SmartSolar controller includes a programmable Load Output that helps protect batteries from excessive discharge. When battery voltage drops below a preset level, connected loads are automatically disconnected to prevent damaging the battery.

Victron’s intelligent BatteryLife algorithm goes one step further. If the system cannot achieve a full charge due to poor weather or limited solar input, the controller gradually adjusts the load disconnect voltage until the battery is able to reach a full charge again. This smart feature helps maintain battery health and significantly extend battery lifespan.
