SSD-25RM Morningstar PWM Solar Charge Controller 12V 25A SunSaver Duo with Remote LCD

Morningstar SunSaver Duo SSD-25RM PWM Solar Charge Controller with Remote LCD

The Morningstar SunSaver Duo SSD-25RM is purpose-built for systems that need to charge and manage two separate 12V battery banks from a single solar array — a common requirement on boats, RVs, and off-grid cabins where a house bank and a starter battery need independent management. With 25A of PWM charge capacity and an included remote LCD meter, you get complete visibility and control over both banks without needing a separate monitoring system. It's the kind of thoughtful, integrated solution that makes Morningstar a trusted name in solar.

Key Features

• Dual battery bank management — independently charges and manages two 12V battery banks from one solar array
• 25A PWM charge control — high-current output for larger 12V solar systems
• Included remote LCD meter — displays voltage, current, and system status for both banks
• Automatic battery prioritization — charges primary bank first, then secondary bank
• Low voltage disconnect (LVD) — protects both batteries from over-discharge
