Hey everyone and greats from Gelsenkirchen ! A lot has happened for all of us lately. I’mm stuck on the following scenario.

My setup includes 3x MP5000, 5x MPPT 150/35, three AC-coupled Growatt inverters, and a 25 kWh battery. Monitoring is working, as well as the switch with AC-out to the HIM 406.

Right now, AC Tec has a deal on the Growatt 3600 Hybrid. I already have three of them, along with 30 installed panels, and they arere running great. Thats the current situation.

The Growatt inverters are black start capable and support backup power, working with the Pylontech BMS (my battery BMS).

I would like to connect them only via the DC side, instead of through AC like the others. But Im completely stuck on the communication between the two systems.

Anyone got a plan?
