I’ve developed a commercial energy management system based on openHAB that essentially can operate the major electric consumers in a household with excess power from a solar plant.
Planning to extend it to become compatible to more pv inverter models, I’m looking for volunteers to own any such “new” inverter that is willing to install my EMS on their site and
help with development by testing it with their PV equipment.
For the most part your part will be to test and validate modbus (or proprietary in some cases) binding communications to the inverter. So if you already have your OH configured to talk to and also even have admin access to your pv inverter (yeah, German regulatory madness …) , it’s you I’m looking for.
Preferrably you have a battery, too, and eventually an EV as that’s a prime consumer to also test car communications against, but any OH-connected ON-OFF-controllable consumer will mostly do.
You will be rewarded with a free EMS copy for your efforts. And subsequent energy cost savings 
See this thread for some more details. The EMS is on sale, for general information see https://storm.house/energiemanagement-system/ (German only, use a translator).
Thank you.
