Differenz in der Erfassung der verbrauchten KW im EVCS Charger und Portal Dashbord

Hallo,
mir ist aufgefallen dass die Anzeige der verbrauchten KW im Display des Chargers und der Anzeige im Dashboard nicht übereinstimmen, so z.B gestern wurden laut Charger 6,42 kwh geladen, im Dashboard sind es aber nur 5,3 kwh, woher kommt dieser Unterschied?

Guten tag,

For more precise measuring my advice would be to use a dedicated power measuring meter. those build in measuring devices are for indication of proper function only.

Hello,

What would be an appropriate measuring device that could be installed additionally, or do you mean a normal three-phase electricity meter for the DIN rail? I would like a solution that I can read remotely on the dashboard.

best regards
Torsten

supported meters by Victron are:
Carlo Gavazzi

Hello, i have an EM540 installed, but can i use a senscend one? But more than 100 EUR for another Power meter is mutch money. I dont understand why the Charger not send the Charingpower data to the cerbo GX and from what source the Cerbo GX gets the current data.

best regards
Torsten
