A solar charge controller regulates the voltage and current coming from your solar panels to your battery. It ensures the battery is charged safely and efficiently, prevents overcharging, and stops power from flowing backward from the battery to the panels at night.

A PWM (Pulse Width Modulation) controller is a simpler, cost-effective option suited for smaller systems, while an MPPT (Maximum Power Point Tracking) controller is more advanced and can convert excess panel voltage into additional charging current - improving efficiency by up to 30%.

Choose a controller that matches your system voltage (e.g., 12V, 24V, or 48V) and can handle the total current (amps) from your solar panels. Always allow some headroom - selecting a model rated about 25–30% higher than your maximum expected solar current for reliable performance and longevity.

Install the controller in a cool, dry, and well-ventilated area that is as close to the batteries as possible to minimise voltage drop. Avoid direct sunlight, water exposure, or enclosed spaces that could cause overheating and reduce performance.

Yes. The Alvolta charge controllers include built-in LCD screens and Bluetooth connectivity for app integration to show key system data such as charging current, battery voltage, and solar input power. This helps monitor system health and optimise your energy performance.
