With fantastic help from two of the contributors I have now learned how to decode the ModBus registers from the SolarEdge inverter. It is fitted with a WattNode meter which also uses ModBus.
I have so far decoded as far as register 40189 on page 19 successfully. The main data I need is in the Export+Import section but all the registers beyond 400189 appear to be either zero or 32780. As far as its worth empty.
Ive seen a few posts about SolarEdge Modbus and was hoping someone's got any further than this.
Has anyone successfully decoded
