Enerdrive MPPT Solar Controller, 40A

Enerdrive MPPT Solar Controller 40A – MPPT Solar Charge Controller for Caravans

The Enerdrive MPPT Solar Controller 40A is the link between your solar panels and your battery bank. Using advanced MPPT (Maximum Power Point Tracking) technology, it extracts up to 30% more energy from your solar panels compared to older PWM controllers — meaning more battery power for the same panel investment.

At 40A output, this controller suits a solar panel array of up to 600W (12V) / 1200W (24V), making it ideal for medium to large caravan solar setups. The LCD display gives you real-time monitoring of panel input, battery charge state, and load output.

How do I know which amperage controller I need?

The controller amperage should match your solar panel array output. A rough guide: 20A suits up to (see 20A model) of solar at 12V, 30A suits up to 450W, 40A suits up to 600W. If you're unsure of your solar setup requirements, contact us for advice.

Is this compatible with my lithium battery?

Yes. The Enerdrive and HiTech MPPT controllers support LiFePO4 lithium batteries. Ensure you select the correct battery type in the controller settings for optimal charging.

What is the difference between MPPT and PWM controllers?

PWM (Pulse Width Modulation) controllers are simpler and cheaper but waste potential energy by reducing panel voltage to match battery voltage. MPPT controllers continuously find the optimal operating point for the panel, converting surplus voltage into additional current — extracting up to 30% more energy, especially valuable on cloudy days and when panels are not at their peak operating temperature.
