In an ESS system, is there an explanation in the algorithms that justifies that when charging the battery from the solar panels, it takes more energy from the electrical network when we are in a parallel model than when it is just an inverter? as well as 10 times more, is this normal? or it may be a consequence of a bad configuration, a firmware update. ( configured with optimization with batterylife )
a) Mode Standalone: In the example, the power of the electrical network fluctuates between negative values and 50w max (normaly). Firmware multiplus II 5.02
b) Mode parallel: In the example, the power of the electrical network fluctuates between 280w and 450w (more or less) Firmware multiplus II 5.05 (both master and slave of course)
In both cases the configuration is the same standalone / parallel and the same with BatteryLife/ without BatteryLife. Cerbo GX: Firmaware in standalone 2.93 / Firmware in parallel 3.00
This is the consumption of the electrical network (in the load from fronius)
Fronius:
I have updated to version 3.01 Venus OS on the Cerbo GX, and the same problem persists
To try and rule out that it is the Venus OS 3.00/3.01 version, it would be compatible to go back and reinstall a previous version, for example the Venus OS 2.94 version.
Would it be compatible with multiplus II 5.05 versions?
and with the latest version of mk3, installed on the cerbo GX Venus OS (which was recently installed)?
