Application scenario:

1. Small household solar power system

2. Outdoor solar power system

3. Portable solar applications

High efficiency MPPT operation scheme, solar panel utilization rate is 99%.

LCD and LED display various parameters, such as input voltage, battery type, battery voltage, charging current, charging power, working status.

The Maximum Power Point Tracking (MPPT) solar controller can detect the maximum output power of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the highest efficiency. The battery charging is divided into three stages of trickle current, high current and constant voltage. If the input power is ideal, the first two stages are constant current, and the latter stage is constant voltage. If it is not ideal, use mppt to maximize power as far as possible to reach the rated constant current or constant voltage value. .

At present, the photovoltaic power generation boosting technology with MPPT is output after being boosted by an isolation transformer. However, the volume of the isolation transformer is relatively large, and the windings need to be wrapped with insulating glue. In addition, the isolation transformer will generate a large amount of heat during operation, so it has higher requirements for the heat dissipation of the MPPT solar controller. Moreover, the withstand voltage requirements for other components in the MPPT solar controller are also high.
