When my Victron Multiplus 2 5000 GX has reached the soc and doesn’t have to charge or to discharge it doesn’t remain idle but switches from charging to discharging again and again when the inductive stove is on, but also on other power changes.
Why is the multiplus not just keeping idle untill dess decides to charge or uncharge?
And can this behavior be changed?
See behavior in the video below…
What is your setting for Settings → ESS → Peak-Shaving?
Set this to “above minimum soc only”, then, while beeing in ESS #1, Peak Shaving should be disabled and therefore the battery stay at 0W load.
I had it set to always and now changed it to above minimum soc only.
And when at minimum soc this behavior is gone, but as soon as I lower the minium soc below the actual soc the behavior is back.
Sure, because that’s what Peak Shaving is supposed to do - shave consumption peaks by switching to discharge whenever a Peak occurs.
And especially (old) stoves or cooking plates don’t have a smooth behaviour. They regulate temperature by bouncing between 0 and 2000 watts every few seconds.
But don’t worry, that’s what batteries are designed to do. It doesn’t “hurt” them.
I understand, but I would prefer an option to disable it as it is unnecessary in our home and also adds up to losses.
Can the option disable peak shaving permanently be implemented?
That’s what Peak Shaving is designed to do, but when “Limit system AC import current” is disabled, shouldn’t that also disable peak shaving? And even if my battery is below it’s minimum SOC, and the AC loads start to get close to 50A, the multiplus will reduce charging to limit the peak draw to 50A, but there is no way I can increase this value for my MPII-3000 above 50A.
@mpvader any change this issue can be resolved in upcoming firmware updates?
I can see the very same behaviour in my system, and I always had set ESS → Peak shaving to “above minimum soc only”. I think that is very normal behaviour and occurs in every system.
This behaviour can always seen when the AC-loads + self consumption is close to PV-power, or when the system is close to 100% SOC at the end of the absortion time, or when the system is close to min SOC.
In these conditions the ESS can not clearly decide wether to charge or to discharge. And since the inverter in discharge mode has a much higher self consumption, the system shows this behaviour.
