The grid-connected inverter is a special kind of inverter. In addition to converting direct current to alternating current, the output alternating current can be synchronized with the frequency and phase of the mains, so the output alternating current can return to the mains. Recently, the grid-connected inverter and feed metering cabinet produced by Nuoyi were used in the hydrogen fuel cell microgrid system of a well-known energy company in Wuhan.
The grid-connected inverter has the following performance characteristics:
1. Adopt ARM-32-bit microprocessor control, reliable, stable and highly intelligent
2. Fast dynamic response and stabilization
3. High voltage regulation accuracy
4. High frequency stability
5. RS485 communication interface (can be transferred to CAN)
7. It has alarm display such as fuse break, high IGBT temperature, high transformer temperature, IGBT fault, overload, input undervoltage, etc.
8. With input non-fuse switch, output non-fuse switch, electronic circuit can quickly detect over-current, over-voltage, overload, over-temperature,short circuit and automatic trip protection and alarm protection functions
