2.2 Schematic Diagram
public power grid via DC filtering, boosting, DC bus decoupling, inverter and AC filtering.
It adopts DSP and MCU dual-chip redundancy technology to realize fault detection and
protection of the inverter. The interior of the inverter has two groups of relays connected
between the inverter circuit output and power grid port, and the groups of relays have
self-test function that can ensure reliable disconnecting of the connection between the
inverter circuit and the utility grid in the event of a failure.
It realizes the remote monitoring of the PV power generation system via the
communication methods of RS485, GPRS and Wi-Fi.
