Relay section
The
allows managing the power in both directions (AC-DC rectifier mode a DC-AC inverter
mode).
To customize the AC side connection with the power converter, we considered four relays. Three of them are for
the three-line connection and one is for the neutral.
You can manually manage each relay (on|off state). The MCU can manage the relays for the grid connection or if
a fault occurs.
