Hi,
We are using a Victron system which includes a battery and PV. We have the following components:
- Cerbo GX Gateway
- MultiPlus-II 48/3000/35-32 VE Bus
- Pylontech battery
- SmartSolar Charger MPPT 100/20 48V
We are reading out the power values of these devices using modbus, however we notices that the total powers don't add up to zeros and we can't figure out where this power in consumed. We read the following registers:
| AC Consumption L1 | 817 |
| Grid L1 | 820 |
| PV power | 789 |
| Battery Power (System) | 842 |
Our system is only connected to one phase. When we subtract the sum of the PV, battery and AC consumption and subtract from the Grid we always get a non-zero value between 20-30 W. We are operating the battery at powers of the order of 100-200 W. Since the power loss of the inverter and slef consumption of the system should be much lower, we were wondering which part of the system could consume this amount of power.
Does anyone have an idea what could contribute to this additional power consumption?
Please let me know if you need additional information.
Thanks in advance,
Finn
