Solaredge meter issue #23

Closed elas00 closed 2 years ago

elas00 commented 2 years ago

Connected to solaredge 3 phase inverter, shows - 3277A, main meter configured as solaredge. IMG_20220709_120542

Any solution?

bobosch commented 2 years ago

The Solaredge inverter uses other modbus registers than the Solaredge meter. https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf Try custom electric meter with the settings "BYTE ORD" HBF & HWF (Byte order of custom electric meter) "DATATYPE" 3 (Data type of custom electric meter) "FUNCTION" INT16 (Modbus Function of custom electric meter) "CUR REGI" 40072 (Register for Current (A) of custom electric meter) "CUR DIVI" 1 (Divisor for Current (A) of custom electric meter)

But it will only measure the PV generation? So it will only show the PV current, but SmartEVSE will not work as expected as it needs the current from Mains

Solaredge inverter measure mains via inepro r380 connected via modbus and is working fine on solaredge app.

Does the value -3277A change or is it always the same? Nevertheless please try custom EM. You can hold the button to fast change the settings. And going backwards will be a little bit faster because highest value is 65530 so only 25458 to reduce :-( Or use serial console.

Value was always the same, now work ok with mains meter configured as solaredge. IMG_20220711_123941

@elas00 can you tell how you connected the charger to SolarEdge to get the data from the InePro meter?
