The SRNE SAA 50A MPPT is a high-efficiency dual-input solar charge controller, designed to charge an auxiliary (leisure) battery directly from both solar panels and the vehicle alternator. Engineered for motorhomes, campervans, boats, and off-grid power systems, it offers intelligent energy management, advanced charging control, and excellent reliability.

This innovative controller automatically charges the leisure battery from the alternator when the starter battery voltage rises above 13.7V, and stops when it drops below 13.2V, ensuring safe and efficient alternator charging. Its MPPT (Maximum Power Point Tracking) technology can support up to 700W solar panels at 12V or 1400W solar panels  at 24V.  The buck-boost DC-DC conversion can deliver up to 65A from the alternator to the leisure battery with up to 98% efficiency, optimising power usage from every energy source.  

The SAA 50A MPPT supports multiple charging modes — solar charging, alternator charging, combined solar and alternator charging, and even solar charging of the starter battery. It’s compatible with a wide range of batteries, including Sealed (AGM), Gel, Flooded (vented), and Lithium Iron Phosphate (LiFePO₄) types. Customisable charging parameters allow you to tailor performance to your specific setup.

In addition it has a built in charger to charge your leisure battery from the grid at a charge rates of up to 50A.

Designed for energy efficiency, it consumes just 0.6W in standby mode. When connected bluetooth, you can access real-time system data, historical logs, and parameter settings via the SRNE mobile app for complete control and monitoring.

The SRNE SAA MPPT is truly an all round device at a fraction of the cost of individual devices.
