In a photovoltaic system, the cost of the inverter is less than 5%, but it is one of the decisive factors for the power generation efficiency. When the components and other accessories are exactly the same, if different inverters are selected, the total power generation of the system is 5% to 10%. % difference, the main reason for this difference is the inverter. The MPPT efficiency is the key factor in determining the power generation of the photovoltaic inverter, and its importance even exceeds the efficiency of the photovoltaic inverter itself. The efficiency of the MPPT is equal to the hardware efficiency multiplied by the software efficiency. The hardware efficiency is mainly determined by the accuracy of the sampling circuit, the MPPT voltage The range is determined by the number of MPPT paths, and the software efficiency is mainly determined by the control algorithm.

The full name of MPPT controller is "maximum power point tracking" solar controller, which is the upgrading product of traditional solar charge and discharge controller.

All recent models of digital MPPT controllers available are microprocessor controlled. They know when to adjust the output that it is being sent to the battery, and they actually shut down for a few microseconds and "look" at the solar panel and battery and make any needed adjustments.

MPPT tracking efficiency not less than 99.5% Charging conversion efficiency up to 98.6%.

Full load efficiency of 96.6% two working modes are optional.

Charge priority or load priority support battery and lithium battery Various battery types support battery-free mode.
