Whats the best way to see activity on L2 using ESS

I'm running a DC coupled ESS system (mode 1). My panel is split phase not 3 phase. I have essential loads on AC out 1 Connected to L1 in the breaker panel (120v). I am not currently using AC out 2 for non essential loads they are still in the breaker panel. Aside from moving those loads to AC out 2, What alternative do I have to to monitor L2 in VRM and have ESS take it into consideration? I do have an EM24 That is not hooked up to the system. But if I use it it supersedes the current monitoring of the multiplus plus, that is my understanding. Any suggestions?

In the vrm you can see the two outputs in the advanced tabs. Just load the widget for it. This is just one example, you can see it in watts as well. So look for the several options.

@Alexandra But I do not have phase 2 (L2) running through the Multi as the Multi's 120V circuit is only on L1 and I am not using AC OUT 2 for non essential loads, which are the loads I wish to monitor.

AC Out 2 is not L2. If you want separate monitoring the only way is more meters.

@Alexandra Sorry, I made this unclear, bad wording. I understand AC OUT 2 is not L2. What I meant was, how can I monitor the remaining non-essential circuits in the breaker panel, which happen to be on the other leg of my split phase system, I sometimes refer to them as L2 as I have the AC IN to the Multi on a dedicated circuit on L1 and everything else moved over to the other side so to speak. But I think you answered the question, additional current sensor (CT). So, what I was wondering, if I used a CT, wouldn't that interrupt the current monitoring in the Multi, messing up ESS since it makes the Multi's CT redundant?

In this article.

See #6

You should be able to see L1 and L2 outputs but the AC1 and 2 on each leg will be combined.

@Alexandra Ok great, but for clarity, I need to be using AC out 2 as well, correct. And I have the Multi II, not the GX version. Will it work for the II (non GX)?

@Duswami

Yes, you do have a GX added to the system.

Do you have 1 or two inverters here? Or is it the split phase unit?

I think I have my wires crossed here assuming you are working in split phase.

If it is one, the GX 'sees' ac1 out and ac2 out as one load, not discernable unless they are metered externally separately.

The difference between ac1 and ac2 out is that ac2 out is programmable. In other words can be programmed to load shed if acin goes out, or can be switched on and off based on load on ac1 or on SOC.
