20A 12V 24V LCD Solar Panel Lithium Battery Regulator Charge Controller USB

If you are using lithium batteries with your solar power system, you will need a lithium battery compatible solar controller. Lithium batteries require a slightly higher charging voltage than standard lead acid battery solar controllers which often do not have the option to select lithium battery type. A standard lead acid battery solar controller may reduce the cycle life of your expensive lithium battery.

Product features

12 or 24 V Auto switching

Intelligent 4 stage PWM charging: bulk, absorption, equalising, floating

LCD display with backlighting shows operating data

Supports lead acid battery (sealed, gel, flooded) and lithium battery (LiCoMnNi02, LiFePo4)

Multiple load control modes: 24 hours working control, light control, light and dual time control;

Automatic temperature compensation and accumulated function of charge and discharge KWH

Dual USB output 5V / 2A

User Adjustable Maximum charging current (this is very important for lithium batteries, for example a 12Ah battery may have a max charge current of 5A therefore if you connect this to a 100w solar panel with a 5.6A full output, the lithium battery bms will stop the battery charging if the solar panel exceeds 5A)

User Adjustable Load disconnection voltage (if the battery gets too low)

User Adjustable Load Voltage re-connect voltage (the load output will not switch on until the battery to recharge to user selected voltage)

Suitable battery types: Sealed lead acid; Gel lead acid; flooded lead acid; user defined lead acid; Lithium LiFePO4 4Sx3.2v=12.8v; Lithium LiFePO4 5Sx3.2v=16v; Lithium LiCoMnNio2 3Sx3.7v=11.1v; Lithium LiCoMnNio2 4Sx3.7v=14.8v

Load Output timer options: 24 hour always on; Load On sunset to sunrise; Load On 1-15 hours after sunset; reversed light control - Load On - sunrise to sunset; Load on 1-15 hours before sunrise.
