Product Description

The Morningstar SunSaver DUO Controller is engineered for high‑performance dual‑battery solar systems, offering 25 amps of charging capacity and tailored features to manage two battery banks from a single solar input. The Morningstar SunSaver DUO Controller allows users to select charging priority (e.g., 90%/10% or 50%/50%) between Battery #1 and Battery #2, ensuring the proper battery gets primary charging until full, then the full current transitions to the second bank. With the Morningstar SunSaver DUO Controller you benefit from temperature compensation that optimizes charge set‑points based on ambient conditions, extending battery life and stability. The Morningstar SunSaver DUO Controller includes epoxy‑encapsulation, corrosion‑resistant terminals, a remote meter option for real‑time system read‑out, and full electronic protections (reverse polarity, over‑current, high temperature). Ideal for RVs, boats, cabins, security shelters and remote monitoring sites, the Morningstar SunSaver DUO Controller simplifies dual‑bank solar installations, improves reliability and reduces overall system cost by replacing two regulators with one. Whether charging a “house” bank and an engine starter battery or two equal‑sized banks, the Morningstar SunSaver DUO Controller delivers professional‑level charge regulation with proven ruggedness and ease of use.
