Solis Wechselrichter (S5-EH1P4.6K-L) via Modbus auslesen

[macfly]

Moin zusammen,

ich bin so ziemlich fertig mit dem Auslesen der Daten vom Solis Wechselrichter mit einer einfachen Zweidrahtleitung und einem rs485<->usb adapter. Falls Interesse besteht, kann ich die Definition des Devices hier gerne posten.

Allerdings habe ich noch eine Interpretationsfrage zu einigen Registern (lt. Doku vom 15.9.2020):

33151, S32, AC_Inverter_Power, "Inverter AC Grid Port Power - 1<-->1W, + to grid, - From grid"
33157, S16, AC_Inverting_Power, "Inverting Power/Rectifying Power - 1<-->10W"
33147, U16, AC_House_Power, "Household load power - 1<-->1W"

hat jemand verstanden, was diese Register genau bedeuten? Ab und zu ist AC_House_Power und AC_Inverter_Power identisch, ab und zu nicht. AC_Inverting_Power ist immer kleiner, manchmal auch 0 (tagsüber), manchmal ist auch AC_House_Power 0, niemals jedoch AC_Inverter_Power.

Würde mich freuen, wenn da jemand eine Idee zu hätte ..

liebe Grüße,
Friedhelm
