Not powering from inverter + sensor state unknown

[D43DBULL]

I have some trouble getting this to work. The esp 8266 is working when connected to usb and the sensors are showing, but all states are unknown. And when I plug it in the inverter and unplug the usb the esp won't power on. I did bridge the ground to test if that would work, and it did power on the esp but still the sensors states where unknown. I also see no activatie (leds blinking) on the ttl to rs485 board, I have tried multiple boards but no changes.

Can you spot something wrong?

Sorry for the late reply, I've only just seen these issues. I haven't got notification on. Looks like I have missed something in the instructions. There is a small green wire bridging the ground on the RS485 board. See image below: Sorry about that.
