Widget dual graph meaning

I asked this question two days ago but had no conclusive reply.

I do not understand the meaning of the two graphs accompanied by the two values of my twin Multi in-parallel widget, at any one point, there are different representations and current values.

Can someone please explain or tell me where I can find the information?

It appears you have turned on Show Range Values. This plots the highest and lowest values recorded during the individual time points shown.

Check using the cogwheel icon top right of the graph.

Thanks, I'm not sure I understand, how can there be two different values at the same time? I was worried that it could be the values of the two inverters but it seems not.

Each time point on the graph is a value for a time period. During that period the voltage and current fluctuate. Normally this is averaged into a single value for each of voltage and current.


For example if the highest value in a time period is 10A and the lowest is 5A the graph shows values at 5 and 10A and shades in between.

Many thanks

Got it now, so it is a fluctuation during a short period of time.

So I guess there is no way to know the values of the two inverters since, being in parallel, they act as one phase.

I am trying to investigate the balance in outputs as I often get an overload warning message that only lasts 24s.

@Logic28

"I am trying to investigate the balance in outputs as I often get an overload warning message that only lasts 24s."

Bear in mind that overload (and other) warnings take around 20s to clear, even if they're only a mS spike. And that spike may never get registered on VRM or even Victron Connect with per-second sampling.

I've had them regularly for years and have never seen them on a graph. But I know the cause, a water pump starting. I ignore it..

Yes, in my case it is the inductive load of the Hydrovane compressor sometimes in conjunction with a secondary load. Strange because it is only a 2Kw unit which spikes at 5.6kw.

Thanks for your comment, I shall try to ignore them in this case.
