Wireless CT clamp

[mbu10]

Good morning
The inverter is a long way from the grid input
Is there a way to wireless the CT clamp
Or is there a way the H1 can talk to the mqq feed from my grid meter, (glow) this feeds my home assistant and updates every 6 secs
Or something
Thanks
Martin

You can’t talk to the smart meter, and unfortunately there is no (that works) wireless option for the CT clamp.

You can install an RS485 (Chint or Eastron) and then use a LORA device to transmit the signal to the inverter - but in all honesty as much as a pain as it is to run wires try and use a wired CT clamp.

Link below for a known working LORA device using the Fox recommended Chint or Eastron meters.

What is the maximum length the CT cable can be in this scenario?

Ideally 10 metres but using cat6 cable (shielded twisted pair) you should be good for 20-25 metres if it’s not a ‘noisy’ environment, beyond that consider using either a Chint or Easyron meter and run over RS485 instead.
