Tesla’s solar CT’s (connected directly to gateway, Nero’s are fine) are calibrated about 10% high. Probably on purpose so people think their solar is working well. So if all loads are off, the solar CT’s should match the Line CT’s. Seems like the calibration is looking for the lowest house...

Turn off all loads/breakers and let the solar calibrate with the main CT. I think Tesla finally figured out that their solar CT is off 10%. If all loads are off as well as Powerwall then solar has to match the main CT in the gateway. Don’t turn off gateway main breaker, just the loads and let...

For PW2/+ it is AC, for PW3 the MPPT charge the batteries with DC so I think it will be a mix!

That is why I said “It would be cool if Tesla made a separate box”; and that is why it would have a disconnect switch. It could even check the THD to protect Tesla’s hardware. Would probably need some sort of circuit to help synchronize generator. I would probably fork over 2K for said box...

It would be cool if Tesla made a separate box with a generator disconnect switch that could be connected to your generation panel. Probably require a few chips to connect to canbus and check for stable voltage and have CT’s to monitor load be applied to generator.

New solution. Buy a cybertruck and charge it with the generator and then connect truck to house!

Tesla’s EVSE equipment is capable of load sharing. Even tho you have two charger circuits you could set the chargers to load share to play nicer to the grid, if that would work for your vehicle usage. Because of the amount of utility scale solar on the grid, the rate is really low during the...

YES

Have Tesla adjust your current limit in the software. This way the powerwalls will adjust the Powerwall draw to no trip your main breaker. You might think about EVSE that can PowerShare a single circuit too.

MPT/battery chargers can handle more power than the inverter. So perhaps Powerwall is charged already and is clipping what goes to the grid. Really only applies to PW3’s with a lot of solar.

Correct on edit. Inductive loads without correction cause the current to nearly double. Saw this with my well pump motor. I don’t have many capacitive loads, but it is possible some installed the wrong run capacitor on a motor that comes on.

Have any of you taken electrical fundamentals in college?

Could you or a neighbor on the same transformer have a bad run capacitor on a large pump motor?

what is your feeder cable gage from the meter to the loads panel, material and length?

What is the inductance of the load you applied that cause the voltage rise? Do yourself a favor and buy DVM capable of real power measurement. Answer always lies there.
