How did you solve this issue?
We have the same issue, the ET340 gridmeter disconnectes every minute for about 5 seconds, and so on. We already changed the ET340 and the RS485 cable. Both ET340 were running on firmware B-7.
Could this be a firmware issue? And if yes, how should we update the meter?
Best regards,
Willem
Just wondering if anyone has the problem with an EasySolar II 48/3000/35 + ET340 and 5m RS485 to USB adapter that keeps connecting and disconnecting?
Also multiphase regulation doesn't seem to work. Won't discharge battery to compensate for energy usage on other phases.
Thanks,
Still having the same issue, also after replacing the gridmeter for a EM24.
Does anyone have a solucion?
My ET340 works perfectly. Just make sure to connect as follows,
Bonus tip, connect terminal 7 to terminal 9 for bus termination (for longer cable runs).
