Solar power generation system

The off-grid solar power generation system's energy regulation transfers to DC or AC loads. On the one hand, the solar controller (including wind and solar PV controllers) regulates and controls the power generated by the load. On the other hand, the solar energy battery controller stores excess battery energy to meet the load's requirements. No electricity is generated. The controller controls the battery until it is fully charged. The stored energy at the end of the battery discharge cycle protects the battery when the solar controller is not fully discharged. This significantly impacts the battery's lifespan and ultimately affects system stability, leading to controller performance degradation. Second, the solar battery's role in energy storage is to ensure power to the load at night or on rainy days. Third, the solar inverter converts direct current to alternating current to power the load. Solar PV inverters are a key component of wind power generation systems. They are used in relatively remote and difficult-to-maintain solar and wind power systems, improving overall performance and ensuring long-term, stable operation of the power plant. Furthermore, given the high cost of new energy generation, the efficient operation of solar inverters is crucial.
