Why This Product

Building a reliable 12V power system is about more than just a battery — it's about charging it correctly, monitoring it accurately, and trusting it when you're off-grid. Cheap, unmonitored charging is the quickest way to ruin an expensive battery and end up without power when you need it most.

Victron Energy is the benchmark for off-grid and mobile power, and the SmartSolar MPPT 100/30 Charge Controller brings that quality to your build with smart, app-connected control and a proven charge approach. At 4Matt Campers in Cape Town, we help clients put together complete, properly matched 12V systems — so your power works the way it should in real South African conditions.

Key Features

• 30A maximum charge current – Efficient MPPT charging for 12V and 24V battery systems (auto-detected).
• 100V maximum PV input – Connect a solar array within the controller's voltage window for off-grid charging.
• Ultra-fast Maximum Power Point Tracking – Harvests more energy from your panels, especially in changing or cloudy conditions.
• Built-in Bluetooth – Monitor solar yield and configure the controller from your phone with VictronConnect.
• Up to 440W (12V) / 880W (24V) PV array – Match your panel wattage to the controller for the best results.
