Hi all, I have a weird situation happening with my very recently installed FoxESS Smart H3 AC3 15kW inverter + 4800 series ~42kw battery system, which is AC Coupled to my existing nearly-two years old GoodWe 15kW PV inverter, with about 14.5kW coming off the solar panels in full sun/mid-Dec, etc. I'm on three phase with Jemena in Victoria.
The FoxCloudv2 app shows that when full sun ~14kW is coming off the roof, it appears like the house is using almost all of the power, and only exporting a small amount and also only charging the battery very slowly. There is Chint DSU666 meter and it shows -4.5kW per phase, so that power and measurement was definitely there for the detection by the Fox inverter...
See this screen grab where it was the middle of the day, full sun, and the pool pump + pool heater is running:
You can see - only just - that the Gen load is 14.2kW, but the home usage is showing 11.9kW, which is completely wrong for only the HRV, Pool pump+heater, and the HW compressor running at the time, about 100W + 6kW + 700W, nowhere near the ~12kW the app is showing. And that then means - somehow - that only 2.34kW is charging the battery, terrible rate.
I then turn the pool pump+heater off and get this:
...and even then, the 2.45kW usage seems too high for what is running, but it obviously comes down radically and the battery finally starts to charge at a reasonable rate; in fact, I left the pool equipment off and the battery charged from 70% to 100% in about 1hr. The worry here is the system configuration and/or wiring is misreading the house usage quite substantially and therefore not charging the battery sensibly. And yes, I am very sure the pool gear cannot possibly be using near on 10kW for pump+heating, otherwise I'd probably never run the damn thing, especially given I also run the house AC which would be another 4-5kW, and I don't exceed the solar input, as I don't get charged that on any electricity retailer bills, etc., etc.
I am still waiting to hear from the installation team as to what they think is wrong, but wondered if anyone here had a similar issue or had seen this before?
I should add / note that it sort-of seems like there's either double the reading of actual house use, or maybe triple...really odd.
Sounds like the installer has something running backwards
2.5kW isn't much power, honestly

Yes, I suspect something is detecting one of the phases backwards, given these two grabs, first at night with not much running, 548W being used in the whole house:
and then if i turn the microwave on:
you can see it looks like the microwave is providing power - i wish it was! But I'm actually pulling power from the grid instead, plus there's no way my microwave is using 3.7+kW, i.e., the off-set of the previous 500W and -4.21kW, I think it's 1.2kW model, if that.
Can Fox look to see what is wrong here remotely, or do I need my installers to physically return to correct this, do you reckon?
