Power jump if MP2 switch to float mode

Hello,


I have a MP2 5000. I control the MP2 power with external software via MK2 interface.
I observe that the MP2 has a jump in power if the MP2 switch to FLOAT mode.

I watch the power with extra single phase meter (SDM120). You see in the measurement:
blue = power MP2 (> 0.0 = deliver power to grid / < 0.0 = load the battery)
red = the grid power

So the grid detects a delivery of power and the victron shows a jump. After that the MP2 shows FLOAT mode.

double check: battery voltage (16s pack):
orange big line: SOC (jumps to 100%)

You lost us at external software.

What causes the soc to jump? where is the reading from?

Not even sure if there is a question here?

Usually when an inverter switches to float it is a discharge down to that level. Shown by the voltage drop in cells. When do you consider your battery fully charged at the end of absorption? Most people do.
