At present, MPPT controllers are generally divided into high voltage and low voltage, starting from 150V to 200V. Those exceeding 600V, 850V or above are called high voltage MPPT. Naturally, if the solar input voltage increases, the battery connected to the MPPT controller must also be replaced with a high voltage, such as 192/240/360/384VDC. Usually, if it is a high voltage battery, then the high capacity will also come with it, so the body itself must be matched accordingly to maximize its effectiveness.

With the development of energy storage, high voltage batteries are now upgraded to stackable lithium batteries, that is, lifepo4 batteries. The combination of solar energy and urban power grids has continuously increased the available energy and can better cope with complex and changing power consumption environments. Therefore, MPPT plays an important role.

This high voltage MPPT for 192V batteries weighs 45KG. It is a mature and excellent industrial and commercial solar energy system that can use array 18KW solar panels; this is the measured data. It is estimated that this high-voltage MPP controller can support a solar panel area of nearly 100 square meters.
