Internal two core modules
1. MPPT DC/DC Photovoltaic Conversion Unit
The output of photovoltaic panels varies with the change of light, and MPPT adjusts the voltage in real time to track the maximum output power of photovoltaics.
-Photovoltaic direct current can be directly sent to the DC bus;
-Excess photovoltaic energy is charged to the energy storage battery through a DC bus.
2. Bidirectional AC/DC PCS Converter Unit
Bidirectional, electrical energy can flow in both directions:
-Inverter direction (DC → AC): The DC power of the DC bus (photovoltaic/battery) is reversed into AC power at the power frequency, which is supplied to local loads or fed into the grid;
-Rectification direction (AC → DC): AC power in the power grid is rectified into DC power and placed on the DC bus to charge the battery (at night or when there is insufficient photovoltaic power).
