12V24V 20A PWM Solar Controller Automatic Identification Solar Controller fit for Lead-Acid Lithium Battery Lithium Iron Phosphate Universal Photovoltaic Charger

Features:
(1) Automatic identification of three-speed current of DX machine (60A/50A machine is 12V24V48V. 10A-40A machine is 12V24V automatically identification), three types of batteries are universal (lead acid battery, ternary lithium battery, lithium iron phosphate battery is universal) are built-in fan to dissipate heat, better extend the service life of the machine and improve conversion efficiency
(2) The lithium battery is fully charged and has a adjustable voltage, which is better compatible with the different number of lithium battery strings on the market and the diversified voltage needs. (The previous controller's full voltage was not adjustable)
(3) Multi-stage charging effectively prevents battery overcharging and improves battery service. (The previous control was to charge the PWM switch in two sections)
(4) The system voltage is optional, which flexibly meets the needs of users to work in a single voltage system mode. (The previous controller could only automatically adapt to the system, and could not artificially choose the working system)
(5) Short circuit protection can be set
(6) The temperature can be maintained at the rated current and will not reduce the current
(7) With PV overvoltage protection, the PV voltage will not burn the machine due to excessive PV power used by users.
