The charging program of the lead-acid battery and lithium battery series is optional. The solar MPPT controller has an automatic protection function against overcharge, overcharge, and short circuits. The RS485 communication interface has a communication distance of 1km. It communicates with the upper computer to view the operating parameters of the solar MPPT controller. This controller is used in the solar off-grid system (independent system), Automatic regulation of charge and discharge control has a progressive tracking algorithm to obtain the maximum power of solar cell modules and charge the battery; At the same time, Its low voltage is disconnected (damage caused by excessive discharge of LVD pool. The battery charging process of the solar MPPT controller is optimized to prolong battery life and improve system performance. Its comprehensive self-test and electronic protection functions can avoid controller damage caused by installation errors and system failure.

MPPT controller features
Efficient Power Management in Solar Systems with MPPT Controllers
(1) Input energy of MPPT controller = output energy of MPPT controller
(2) Input voltage Input current = output voltage x output current *Assuming an efficiency of 100%, the power loss in the conductor and conversion process is ignored.
Suppose the maximum power point voltage VMP of the solar array is greater than the battery voltage. In that case, the battery current must be proportionally greater than the output current of the solar array, so that the input and output power can be leveled. It is essential in the system because the maximum power point voltage VMP of the solar panel in the solar power system is usually higher than the battery voltage.
