Solar charging is becoming a core component of modern marine electrical systems. The SCM60 MPPT from Mastervolt is a premium solar charge controller designed to maximize energy harvest while delivering clean, precise charging to your battery bank.

The SCM60 utilizes advanced Maximum Power Point Tracking (MPPT) technology to continuously optimize the voltage and current coming from your solar array. Unlike PWM controllers, MPPT actively adjusts to changing sunlight conditions, allowing you to extract significantly more power from your panels—especially in low light or partial shading scenarios.

Proper battery charging is just as important as power generation. The SCM60 uses a 3-stage charging profile (Bulk, Absorption, Float) to ensure batteries are charged quickly and safely while maximizing lifespan. With support for Flooded, AGM, Gel, and Lithium batteries, it can be tailored to nearly any system. When paired with a temperature sensor, it can further refine charging voltage to protect batteries in varying conditions.

The SCM60 integrates seamlessly into Mastervolt systems via MasterBus and can be monitored and controlled through CZone and NMEA 2000 networks. This allows you to view solar production, battery status, and charging behavior directly from your onboard displays or remote monitoring systems.

In larger systems, solar charging can significantly offset generator runtime and shore power dependence. When combined with lithium battery banks and inverter systems, the SCM60 helps create a more efficient, quieter, and more autonomous vessel power system.
