This PWM controller features 3-stage charging process--bulk, absorption and float stage-- for a rapid, intelligent and safe charging to GEL, AGM batteries, including sealed and flooded cells and lithium-iron and lithium-ion batteries. Over temperature protection, over current and low/over voltage are embedded to safeguard your solar panel. And overcharging, over-discharging and short-circuit protection are integrated to offer an extra layer of protection. And dual MOS tubes have been integrated to prevent current from flowing back and at the same time, reducing heat generation and increasing charging efficiency, and its float, cut-off and discharge recovery voltage are user-programmable, which can significantly increase battery life.
Durable Construction: Made of sturdy, flame-resistant ABS, this controller is designed to withstand fire and will not rust.
3-Stage Charging: A PWM 3-stage algorithm, bulk, absorption and float charge, is designed to enhance efficiency and ensure battery lifespan.
Versatile Compatibility: It is compatible with GEL, AGM, including sealed and flooded cells and lithium-iron and lithium-ion batteries.
Electronic Protection: Over temperature, over/low voltage, overcharging, over-discharging, short-circuit, and reverse polarity protection are integrated.
Programmable Voltage: The float voltage, cut-off voltage and discharge recovery voltage can be adjusted to ensure battery safety.
