in the Multiplus II datasheet I read that for Multiplus II 48/3000/35-32 the Cont. output power at 25°C is 2400 W. Where is the 25°C measured? Inside the Multiplus, or ambient temperature at the fan input?
asked
what kind of temperature is used in datasheets?
Ambient. See note 4 on the tech data. FYI this is a standard for electronics rating. White paper here

@Alexandra Thank you, I checked the paper and I understand that this is really an ambient temperature. What I can't figure out is that once tha battery reaches a 100 SoC and the Multipluses start producing alternate curent for the overflow to the grid (almost no consumption in the house), the multipluses do not produce a steady output but start interrupting. See the graph. (I have 3 of them, 3000 VA, cerbo, 10 kWh pylontech batery, Energy Meter ET340)
Interrupted power flow after reaching the 100 SoC:
Thr flow to the grid is very unsteady, plus the Blue Multiplus works hard while the others much less. The work is not distributed evenly.
