I have had a 10kw solar setup since 2019. I recently had 2 PWs (third party) installed awaiting PTO from SCE. City final inspection is complete. My main panel is a 400 amp service integrated with meter. The battery installers ran a 125 amp circuit to a backup loads sub panel next to the GW and moved most of my house loads to it. They left only the larger loads (sub panel to a pool house, 3 ACs, electric ovens, pool equipment, above ground spa, etc.) in the main panel (not backed up).
They did not install any CTs in the main panel at all where the non backed up loads reside. I assume that, because of this, the GW is oblivious to any power consumed by those larger loads. At least that's what it appears from the app. I have the app configured for SCE's 4-9 peak hour plan. I have the reserve for the batteries set to 50%. The plan is to charge the batteries in the early hours of the day and discharge the battery down to the reserve during the 4-9pm peak period to avoid peak hour rates. I see that it does discharge during those hours but it doesn't seem to be affected by the larger loads (that don't have CTs) when they're turned on. Does the system have the intelligence to only discharge the amount of battery energy it thinks is needed based on the CT inputs? Or should the batteries supply energy to all circuits (CT or not) during those hours? Or, will the batteries only supply energy to the backup loads even when the grid is up.
How am I negatively affected by not having CT inputs on these circuits?
If I decide that I want them, what's the best way to add CTs to account for all of my power usage? There are several circuits in the main panel (including the one that goes to the backup loads panel). Is there any way to avoid putting a CT on each and every "load" circuit in the main panel?
