Growatt SPH 4000 Register 1071 <-> 608 #669

Describe the bug

Hello, I have a Growatt SPH 4000 with Pylontech US2000C. Single-Phase Hybrid RA1.0 Firmware RAAA212006 ZCBA-0006 Mode A0B1D0T0PFU2M4S7

For my inverters, “Battery Minimum Capacity” is not in register 1071 but in register 608. If I change the register in plugin_growatt.py it works. Unfortunately, I cannot say how to differentiate between the different inverter types.

I would like an additional switch. Holding Reg Register NO. 00 Variable name OnOff Description Remote on/off On(1);Off(0) inverter On(3) ;Off(2) BDC Value 0,1,2,3 Note The inverter can be switched on and off, and the BDC can be switched on and off for the batt ready function.

Thank you for your work Ingo

My PR https://github.com/wills106/homeassistant-solax-modbus/pull/697 also adds this register.

And, to be precise: 608 is Load First Battery Minimum SOC while 1071 is Grid First Battery Minimum SOC :)
