1、High Efficiency: The tracking efficiency of MPPT is as high as 99%, so this MPPT solar charge controller enables better control over the charging of ternary lithium battery, lithium iron phosphate battery, etc. 2、Stable Operation: Using high frequency switch MOSFETs with extremely low conduction resistance, which greatly improves converter efficiency, reduces the temperature of the entire machine casing, and achieves the smallest casing to achieve greater power output. 3、Buck Controller: The output voltage can be adjusted between 10‑30V, with a button step size of 0.1V. And the input is 17‑84V. Also has clear LCD display. 4、Auto Heat Dissipation: When the internal temperature of the MPPT controller exceeds 65℃ or the charging current exceeds 30A, the MPPT controller will automatically turn on the fan. When the internal temperature of the MPPT controller drops below 45℃, the MPPT controller will automatically turn off the fan. 5、Wide Application: Adopting premium cast aluminum for heat dissipation, ensuring reliable and efficient operation in various working environments. Widely used in solar cars, solar monitoring, household solar panels, RV energy storage power supplies, etc.
