The protection functions are as follows: The overcurrent protection should be set on the AC output side of the solar inverter. When a short circuit is detected on the grid side, the solar inverter should stop supplying power to the grid within 0.1 second and issue a warning signal.
1. Input overvoltage protection: When the DC-side input voltage is higher than the maximum allowable DC array access voltage of the grid tie inverter, the inverter is not allowed to start or stop within 0.1s (in operation) and a warning signal is released at the same time.
Automatic recovery of the grid-connected protection: After the grid-tied inverter stops supplying power to the grid because of the fault of the grid, the grid-tie inverter should be able to automatically send power to the grid 5 min after the grid voltage and frequency return to the normal range for 20s.
Proper inverter management in grid-connected PV systems ensures the stability and quality of the electricity supplied to the grid. An appropriate control strategy is necessary to ensure reliable performance over diverse system configurations and fluctuating environmental conditions.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
