Product color and some functions can be customized(OEM/ODM)
◆ It has an efficient MPPT algorithm, MPPT efficiency ≥99.5%，and converter efficiency up to 98%
◆ Charge mode: three stages (constant current, constant voltage, floating charge), it prolongs service life of the batteries.
◆ Four types of load mode selection: ON/OFF, PV voltage control, Dual Time control, PV+Time control.
◆ Battery system voltage automatic recognition.
◆ Three kinds of commonly used lead-acid battery (Seal\Gel\Flooded) parameter settings fcan be selected by the user, and the user can also customize the parameters for other battery charging.
◆ Natural cooling design is adopted to improve the reliability of the product and prolong the service life of the product.
◆ The input and output of all kinds of protection functions are complete to protect the system.
◆ The use of high strength plastic shell design makes the shape beautiful, and the effective reduction of the product weight can save the transportation cost.
◆ Equipped with 5V3A USB dual output power supply function, support mobile phone and tablet charging products etc..
◆ It has a current limiting charging function. When the power of PV is too large, the controller automatically keeps the charging power, and the charging current will not exceed the rated value.
◆ High definition LCD display function to check the device running data and working status, also can support modify the controller display parameter.
◆ RS485 communication, we can offer communication protocol to convenient user's integrated management and secondary development.
◆ Support PC software monitoring and WiFi module to realize APP cloud monitoring.
◆ CE, RoHS, FCC certifications approved, we can assist clients to pass various certifications.
◆ 3 years warranty, and 3~10 years extended warranty service also can be provided.
