Mastervolt 131902500 - Solar ChargeMaster SCM25 MPPT Charge Controller (25A, 12/24V, IP23) – High-Efficiency MPPT for Compact Systems
The SCM25 MPPT by Mastervolt is a compact yet powerful solar charge controller designed for small to medium off-grid solar setups. Featuring cutting-edge MPPT (Maximum Power Point Tracking) technology, it maximizes the performance of your solar panels, improving charge efficiency by up to 30% compared to PWM-based controllers.
This controller is suitable for use with all traditional 36/72-cell as well as economical 60-cell panels. It automatically detects 12 V or 24 V systems and supports a variety of battery chemistries, including AGM, Gel, Flooded, and Mastervolt Lithium-Ion. With IP23 protection and a robust, humidity-resistant housing, it’s ideal for marine and mobile environments.
