Fox ESS H3-10.0-E and German Law EnWG §14a

[joeylien]

Hi all,

my Fox ESS H3 is finally online and producing great. Our net operator however said that we still need to install a relais in order to allow for the satisfaction of EnWG §14a regulation which allows net operators to limit the intake and output into the net in cases of emergency.

Does anyone here have experience how to realize that with a Fox ESS H3-10.0-E and Chint666 Smart Meter?

Any help would be appreciated.

Many thanks,
Joey!

I believe this feature is called DRM in the user manual and where/how to enable this.

You are right, this seems to be exactly what I am looking for. Thanks so much .

Does anyone here know if the DRM connection on the inverter is a "true" 8-wire ethernet connection?

I have my inverter installed in my garage and my smartmeter in my house and I am running an ethernet cable from my house to the garage which connects to a network switch.

I am wondering if I need to run another cable for DRM over there or if I can simply plug the inverter DRM connection into my switch?
