Hi,
i used the ESS config from the very first and observed already a few months ago that the charge current ('feed in' allowed in ESS config) have dropped to ~40% of the max rate (not cloudy days of course). In the very early ESS days, this was not the case (MPPT charge current shows a smooth curve throughout the day). I guess that the loop in Venus is somehow responsible for the control. Are there known parameters (ESS of system config) having influence on this ?
ESS Feed in parameters have been adjusted since it's introduction.
Can you please confirm which firmware versions you are running for each of the Victron devices?
Hi Guy,
the time i've posted the question Venus: v2.32~2, Multi: 429, MPPTs: 1.39 - since then i've upgraded the MPPTs to 1.42 and the behaviour is getting better - but not as smooth as in the old days ;-) DVCC and SVS are 'on'. Less often then before, i saw the yellow LED at the MPPTs 'on' for a few seconds and very close to that, a reduction of the charge power.
best regards,
Martin
