Product Description

The Morningstar SunSaver 20A Controller (SS‑6L‑12V) is engineered for high‑performance solar charge control in 12 V systems requiring up to 20 amps of charging capability. The Morningstar SunSaver 20A Controller features a built‑in low voltage disconnect (LVD) that protects the battery bank from deep discharge by disconnecting non‑essential loads when voltage falls below safe thresholds—and reconnecting them when safe. With the Morningstar SunSaver 20A Controller’s temperature compensation (TC) function, charging set‑points automatically adjust based on ambient temperature to enhance battery health and longevity. The Morningstar SunSaver 20A Controller employs a four‑stage PWM algorithm (bulk, absorption, float, equalize) and offers sealed/flooded battery mode selection for optimum versatility. Designed for rugged applications, the Morningstar SunSaver 20A Controller comes with epoxy encapsulation, marine‑rated terminals, anodised aluminium housing and approval for hazardous‑location use—ideal for remote electrification, telecom shelters, off‑grid RV/marine use, security and monitoring systems. Simple to install and fully automatic, the Morningstar SunSaver 20A Controller delivers dependable solar regulation, maximises battery life and offers professional‑grade reliability in mission‑critical environments.
