Whats the size of the Goodwe SBP you scored
The 5Kw version.
I think I have managed to stumble on the CAN BUS protocols. As you would expect it looks like they have copied Sunny Boy's Island product, just with a few changes.
Why am I not surprised..

I was discussing these inverter Can bus protocols with an engineer friend recently. He mentioned that SMA were forced by the German Govt to put the protocols on public domain if they wanted German consumers to continue to receive subsidies for their products. I "believe" this is now known as SunSpec ModBus
and has to be used with Demand Response Enabled Modes
for manufacturers to obtain international certification.
The Goodwe SBP 5000 is looks well specified and priced. I hope you can find a way to use these protocols to interface with generic BMS systems.
