Enerdrive 12V/24V 40A MPPT Solar Controller (EN43540)

The Enerdrive EN43540 MPPT Solar Controller is a high-capacity solar charge controller designed for serious off-grid, touring, and high-load power systems. With a 40A charging capacity and automatic 12V / 24V system detection, it’s built to efficiently manage larger solar arrays while protecting your battery investment.

Using advanced Maximum Power Point Tracking (MPPT) technology, the EN43540 continuously optimises solar input to extract the maximum available energy - even in variable light conditions. Compared to traditional PWM controllers, MPPT can deliver up to 30% more usable solar power, making a noticeable difference in real-world setups.

This controller supports lead-acid (sealed, gel, flooded) and LiFePO₄ lithium batteries, with configurable charging parameters, temperature compensation, and a clear LCD display for live system monitoring. Designed by Enerdrive for harsh Australian conditions, the EN43540 is a rock-solid choice for large caravans, motorhomes, marine systems, and remote installations where reliability matters.
