Need Clarification on AC Input Time Delay

I notice that when my batteries are at about 50% SOC and my small refrigerator comes on, the surge of the refrigerator starting will cause my battery voltage to dip, which in turn triggers my AC Input to On.

I don't want AC Input to come on unless there is is a persistent low voltage at the batteries. (Not a transient.)

So I have now set a time delay of 10 seconds on "Connect when battery voltage drops below ..."

I haven't had a chance to see what happens with this new setting. So am asking here for clarification.

Does the "Time Delay" means that the Multiplus simply waits x seconds to enable AC In after my battery voltage dips below threshold? Or does "Delay" mean that the battery voltage has to persist for x seconds - so that transients are ignored - before it AC Input is triggered On?

I expect that it is the former. If so, then a Feature Request for a Setting called "Ignore Transients" where users can set a time window to ignore voltage dip transients caused when equipment starts.

Are you using virtual switch or assistant programming?

Neither. I am using VictronConnect (for Windows). To talk to my Multiplus.

(Settings > AC Input Control > Delay before Connection.)

There are several time delays that can be set there, both on load and voltage.

Would you mind sharing the settings?

You may have a conflict on settings.

@pmikep

Have you tried the soc and voltage combination? You mentioned it in your post as 50% where the problem is.

The delay is supposed to help with transients from my understanding i did mean to state that since it was your question.

So with soc and voltage, what you will be telling the system is to connect to sustain the voltage you set but not above a certain soc.

I was hoping to replicate your program but dont currently have a 24v system to play with at home.
