I would like to build a installation with a MultiPlus 2 and ESS in Germany.
I have now learned that all inverters since 27 April 2019 must have VDE-AR-N 4105:2018-11.
But i only found the "Certificate VDE-AR-N 4105 MultiPlus-II and MultiGrid-II 48/3000".
Inside it says "VDE-AR-N 4105:2011-08".
Someone can tell me if I can build that up and register with the existing certificate.
Or do I have to wait for a certificate with "VDE-AR-N 4105:2018-11"?
Suggestions welcome. Thanks.
