Solar panel controller 20A 1224V

Solar panel controller 20A, 12/24V. The voltage controller is dedicated to all types of lead-acid batteries (OPEN, AGM, GEL). Suitable for lithium-ion (ternary lithium batteries) as well as lithium-polymer (lithium iron phosphate) batteries. The voltage regulator is exclusively dedicated to solar panels. Never connect other power sources to this regulator. The built-in controller allows parameter adjustment. Fully 3-stage PWM charging management. Built-in short-circuit protection, reverse polarity protection, overload protection. Dual MOSFET reverse current protection. The controller supports lithium battery and lead-acid battery types (in the battery type interface, hold the setting switch button for 3 seconds); default is lithium battery.
