40 Amp 5-Stage PWM Charge Controller

The Zamp Solar 40-amp charge controller can regulate up to 800 watts and is compatible with Lithium, Gel, AGM, Conventional lead-acid (wet) batteries, and LTO.

Lithium Battery BMS Wakeup Feature
Integrated solar boost functionality will deliver the power necessary to wake a BMS (battery management system) when a hibernation event is triggered resulting in a non responsive battery. Simply the solar controller to get your system back on track and charging again. 

Protects and Regulates
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 back flow 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.

Flexible and Customizable
Our 40-amp charge controller is weather resistant and can be surface-mounted on your wall, or flush-mounted inside the wall. It is compatible with our battery temperature cable and with our remote LCD display that lets you keep tabs on your power from wherever it's most convenient for you.
