good morning,
I try calculating the energy flow in my system myself. The system is a simple ESS with solar inverter, multiplus II, Cerbo GX, EM24 gridmeter and pylontech batteries. For receiving the values of the system I'm using MQTT.
No problems are gird W / kWh in and out, solar W / kWh. But with the battery I'm struggling a bit. I can use the DC values (current and voltage or directly power):
These values doesn't match the values in the vrm dashboard for "to the battery" and "from the battery".
I assume the difference are the charger looses. If I calculate my total energy usage with the DC values, these looses will be part of that total. Is there any possibility calculating the power/energy in and out of the charger?
Thanks a lot,
Markus
