15A MPPT Dual Battery Charge Controller with App

Merlin's SolarPlex MPPT charge controller is designed to optimise solar panel performance, maximising power output for 12V or 24V batteries. Through MPPT technology, it enhances solar yield by up to 20% compared to standard PWM controllers, actively adjusting the solar panel voltage to match the battery's requirements, regardless of its discharge state. This advanced algorithm ensures maximum power delivery with minimal electrical losses under various weather conditions.

Aside from its high efficiency, the MPPT Controller offers charging and voltage protection for both single and dual battery systems. Whether charging two leisure batteries or a combination of leisure and vehicle batteries, the controller prioritises charging the battery connected to its No 1 terminals until it reaches 70% capacity. Subsequently, it provides a simultaneous and equal charge to both batteries.

For real-time monitoring, a free-to-download Bluetooth App (search pvmobilesuit) connects to the MPPT, enabling Apple or Android users to track solar panel performance and battery data. The MPPT safeguards batteries against overcharging for solar panels or arrays up to 225W, making it an excellent choice for new installations or as an upgrade to existing solar systems.
