The all-new ZampTech PT20 Solar Charge Controller automatically controls solar charging power to protect AGM, Gel, Wet, and Lithium batteries. The ultra-rugged "all-weather" unit comes with a temperature sensor (2.9m), a pre-terminated weather-resistant ATP battery connection (3m), and a pre-terminated weather-resistant ATP solar input adapter.
Protects and Regulates
The patented Pulse Technology ensures an effective desulfation to extend the life of batteries. The temperature sensor is used only with lead-acid/AGM batteries for optimal charging and safe temperature compensation. The adapter allows a bare wire connection to solar input. All our charge controllers use pulse width modulation (PWM) and five stages of charging to regulate the flow the electricity to your battery. This protects your battery from overcharging, expands your battery’s lifespan, and keeps your panel safe from backflow electrical currents, among many other protections and benefits.
Monitors and Indicates
Its large digital display lets you monitor battery voltage, charging current, charging capacity (amps per hour), battery types, full charge, and system faults. Colored LEDs indicate operational status and battery conditions.
