SK-12 Morningstar PWM Solar Charge Controller 12V 12A SunKeeper

Morningstar SunKeeper SK-12 PWM Solar Charge Controller

The Morningstar SunKeeper SK-12 brings the same proven self-contained design as the SK-6 — but with 12A of PWM charge capacity for larger 12V solar systems. Connect it directly between your solar panel and battery with no enclosure or additional wiring required. With integrated low voltage disconnect (LVD), it protects your battery from both overcharge and over-discharge automatically, making it ideal for unattended remote installations where reliability is everything.
