As the core equipment of photovoltaic power generation systems, the inverter is used to convert the direct current generated by photovoltaic modules into alternating current that meets the requirements of the load or power grid. It is one of the important system balance components in photovoltaic systems

The reverse control integrated machine, as the name suggests, is a device that combines the controller and inverter. It can control the solar panel to charge the battery and use the battery to supply power to the inverter, providing overcharging and discharging protection for the battery. It can also convert direct current into alternating current. Its advantages are also very obvious. The combination of the controller and inverter can save installation space and transportation costs even more, In addition, there is the function of wall mounted installation, which makes wiring easier for the entire solar power supply system, adding more possibilities for the application of solar power supply systems, such as RVs and home solar power generation

Municipal electricity priority: Municipal electricity priority is given to power supply. When municipal electricity cannot be supplied, photovoltaic and battery power supply are synchronized to the load;

Photovoltaic priority: Photovoltaic priority is given to power supply, and when there is insufficient light, the municipal power supply is synchronized to supply power to the load; When photovoltaic and mains power cannot supply power to the load, the battery inverts to supply power to the load;

SBU mode: Photovoltaic power is given priority, and when the photovoltaic power is insufficient, the battery synchronously supplies power to the load; When both photovoltaic and battery power cannot be supplied, the mains power supplies the load.

The off grid solar power generation system uses photovoltaic panels as the power generation component, and the controller adjusts and controls the generated electricity. On the one hand, the adjusted energy is sent to the DC or AC load, and on the other hand, the excess energy is sent to the battery pack for storage. When the generated electricity cannot meet the load needs, the controller sends the battery energy to the load. After the battery is fully charged, the controller should control the battery not to be overcharged. When the stored energy of the battery is discharged, the controller should control the battery to prevent over discharge and protect the battery. When the performance of the controller is poor, it has a significant impact on the service life of the battery and ultimately affects the reliability of the system.
