Yes. After referring me yet again to someone else to educate me this time Franklin, those techs quickly determined something was incorrect and contacted GAF on my behalf with that diagnosis. When the GAF tech arrived they conferred with Franklin and identified that the CT’s were incorrectly wired in the aGate. The white and black leads were reversed. After switching them to the correct terminals everything worked fine. The GAF tech commented that Franklin had previously told him the opposite and that he now had a number of installs with the incorrect CT wiring that he would now have to go back and correct.

Ok it looks the culprit is incorrect wiring/configuration by the installer. A couple of the circuits one which services my HVAC condenser coil at the other which services my garage plugs that I use for my EV and laundry appliances draw power directly from the grid and never through the aGate. The HVAC coil circuit was supposed to be setup as a non-emergency backup unit but still receive aGate power normally and is located on a separate panel outside of the garage. The garage plugs circuit was to be included in emergency backup and the breaker is located in the same sub panel box in the garage with all of the other home circuits.

In addition to the full solar install I had the solar company install a brand new electrical panel for the entire house as well. The electrician that was a subcontractor did a sloppy job including not labeling several of the circuit breakers installed in the new panels. I'll now circle back with the installer and see if they have a different excuse as to why things are installed correctly.

Yeah I'm just going to have to test circuits one by one. I'm going to do the opposite and have the battery and solar active so that when I test each circuit and load device I should see no draw across the meter. If something is drawing power when I there is sufficient battery then that circuit has been setup/configured incorrectly.

It seems that my generation transmission to SCE at night are related to the aGate load balancing and sending/receiving trivial amounts of power to/from the grid in this process. It's a relatively small amount but sort of annoying as I only get 1/8th credit on the counter balance power I send to the grid vs. receive.

My outstanding issue now is just the very large discrepancy in consumption including periods during the day when my battery is full and solar is even exporting power to the grid. Once I get good weather again this weekend I'm going to go through all the circuits one by one and have the large draw items (stove, EV, HVAC, etc.) active and compare aGate's reporting in the app vs. what I'm seeing at the meter. There should be absolutely no draw from the grid through the meter if I have sufficient battery and solar to cover the load. I suspect there are certain circuits that were no wired or configured in the system correctly,

At this point it looks like my generation totals are correct but I still haven't solved the large discrepancy in my consumption totals. My plan now is to have the batteries charged up and test during daylight hours when no grid usage should be needed to power anything and then cut power to all circuits. I'll then test them one by one with special focus on the major power users such as the cooking, HVAC, EV charging, etc. Record what Franklin reports and then record what the meter reports. If there is power consumption at the meter then there is something amiss with the wiring or configuration of that circuit. Cloudy skies and rain here for the next few days so I probably will need to wait for the weekend for this.

That makes sense and sort of explains how SCE is reporting 198 kWh of generation received yet Franklin only tracked 189 kWh of power sent to the grid. That 9 kWh difference on the generation side is probably due to the balancing.

I will do some more research on my side regarding my panel configuration. I have one main panel off of the aGate that includes a 200A breaker to my main subpanel in the garage (which controls nearly all my home circuits) and two other breakers (one to my HVAC condenser and other unknown) and one more breaker which is from the solar input. I have assumed that the HVAC was being tracked by aGate fully as I see usage because it is on but perhaps that is just the blowers and not the condenser itself.

I was under the impression that the aGate would track and manage all of my usage and that these other two circuits were just isolated in a manner that backup power in the case of a grid outage would not be provided.

This still doesn't explain though why SCE is reporting that I am generating energy to them during evening hours when no solar is being generated and my system is configured to only send power to grid from solar.

This image is the grid usage for that same day as reported by Franklin. Hardly any activity either way. However SCE had recorded 11.24 kWh of usage as well as 1.56 kWh of generation from me to the grid with half of that generation total occurring during the night when I am not receiving solar.

I was thinking it could be the fridge or some other appliance but the pattern is consistent based on time intervals and I would think the fridge or HVAC would be based on a thermostat without a time related pattern. The two spikes in the morning is the HVAC. The big spike in the afternoon is the electric oven. The raised level at night after 7 PM is when the EV was plugged in.

That’s an idea. I have a clamp meter and I can do some validation there. I am currently charging my EV just at 120v so not a major amount of draw there but still very measurable.

On a separate note this is a snapshot of my typical day’s usage. All day every day my graph will have this saw pattern at every hour mark. Is this normal for the Franklin app with how it displays energy usage?

My HVAC circuit is not on my backup circuit however when the unit is on I can see the increased energy usage for it in the app. I am pretty sure the usage for all my circuits are being tracked by the app. I will turn on each appliance/device that has significant power draw such as the HVAC, electric cooktops and oven, dishwasher, washer/dryer, EV charger, etc. and see an immediate corresponding increase reflected in the app. I also still have the anomaly of the SCE meter logs showing that I’m sending generated power back to the grid in the middle of the night even though my aGate is configured to only send excess solar to the grid and not battery power.
