- Dedicated MPPT controller for lithium batteries; applicable to ternary-material lithium, lithium iron phosphate, lithium cobalt oxide and other types of lithium batteries. - Supporting 12 V lithium batteries; able to activate the batteries automatically. - solar panel open-circuit voltage Voc ≤ 40 V and a max. solar panel power Pm ≤ 100 W. - Providing lithium battery low-temperature charging protection function. When the ambient temperature falls below the freezing point, charging is halted to protect the battery. - Featuring load boost constant-current output; able to directly power a maximum of 12 light bulbs in series, with a max. load power Pled ≤ 60 W. - Boasting the design of load triple-stage brightness adjustment and morning light, with operating duration adjustable from 0 to 15 hours and power settable from 0 to 100%. - able to record system status for a maximum of 7 days; comprehensively and effectively monitoring the system's conditions. - Data communication adopts a multiple-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission. - Providing intelligent power mode, which can extend the battery's life to its top limit by adjusting the load power automatically according to the remaining battery capacity. - True constant current rather than current-limiting control ensures smooth and stable output current, effectively reducing LED light attenuation and extending LED service life. - With infrared remote control function, operations including setting parameters, reading status and viewing historical data can be performed. - The overheat protection function enables the device to scale down or shut off the load completely when its temperature exceeds certain point. - A range of protection measures such as battery reverse-connection protection, LED short-circuit protection and open-circuit protection place the system under comprehensive protection.
