Hi, does anyone know if the Eastron SDM230 Modbus V2 bought from the likes of Amazon (from this thread:-https://diysolarforum.com/threads/growatt-sph-and-power-import-control-from-grid.39897/) will still work with the Growatt SPH series (with the address change to 002 if required) or as stated by another forum member do you have to get Growatt's own version to ensure it works?
I can see a lot of members have bought the aftermarket version and it works but has something changed recently:-
Quote "I had a reply from Growatt support. If you don't buy the smart meter at Growatt, it will not work because Growatt re-write the smart meter registers.
FYI: Growatt smart meters are now CHNT, it looks like they don't use Eastron anymore. Anyway, if you want a smart meter that works with the Growatt inverter, it NEEDS to be in a Growatt karton box. (if not in a Growatt box, it will not work)" or is this Growatt trying to make you buy their own?
