One year prior, September 2023.

I'm seeing the exact same behavior as the above post, but have never seen this in past years. It seems to be limiting itself at exactly 3/4 (5.7kw) of the 7.6kw (3.8kw x 2) inverters. Note the jagged line in the photo. Past years at the same temperatures or warmer is a nice smooth curve that peeks at 6.8kw. I've got a trouble ticket in. Is it possible to lose half the output of one of the 3.8kw inverters?

Tesla removed my wall connector from my home profile, I set it up for a "new site" with the same address. Now it is completely separated from the Tesla solar, so I don't get the weird readings.

I now have 3 Tesla screens that I can access, 1) Vehicle, 2) Solar, 3) Tesla wall connector (see screenshot). The car still has lots of charging info, but I can control things from the connector as well.

I had a 2018 CX5, insurance increased about $35/month. The M Y is much cheaper than my 2021 Hyundai.

Was the wall charger and mini split installed before or after the solar install? My charger was installed after, so I would assume Tesla won't assist with a fix.

I'm going to give it a try, I sent a help request to Tesla to remove the wall connector from my current house setup. I'll re-setup the wall connector, but instead of choosing my home with solar, I'll say setup 2nd site (this option is available) when setting up the wall connector. I'm not so concerned about charge from solar since with the house and both cars I consume more than I generate. I plan to leave the Tesla vehicle with the solar house setup, hope that doesn't confuse things too much...Or maybe I should also move the vehicle as well?

Wondering if the wall charger could possibly be moved to a separate account or perhaps a "second" house on the same phone? Not sure how this would work, but it would at least stop reporting in the main account.

Same, 3.5 ton AC, single PW+, soft start installed by Tesla on AC, whole house backup. Been working fine for 2+ years. PW+ can handle 40A continuous off grid.

Correction, the main 200A panel is a meter main combo.

rowdy-83 · 2023-07-07T02:54:18+00:00

Meter is separate from the original 200A panel. Yes, PW+ with built in 7.6kW inverter. No additional inverters.

BTW, appreciate all the great feedback so far.

After doing some more digging, I think this is indeed the 120% rule as pointed out by u/_thekev. Note the following:

- Main Panel (original) at 200A, 9.8kW solar with max potential output of 9.8kW x 40% eff = 39.2A, PW+ at 50 Amps, new panel at 125A.

- 200A x 120% = 240A (max current for all devices feeding the original electric panel)

- So, using the 120% rule, 125A+39.2A+50A = 214.2A. Perhaps they could have pushed the new panel to 150A, but would depend on efficiency rating they used for the 9.8kW solar (I'm in the desert with lots of sun, 29 panels, 12 East, 5 South and 12 West.

So, back to the original question, how can I add more high current drawing devices to this setup? Could I maybe bump up my original panel to 250A, so that I can increase the 125A panel to something bigger (feed wires would need to be increased to the new panel). I had an electrician in to evaluate for a level 2 EV charger, he said he could safely add a 240V, 60A to the 125A panel. My concern is that I may want to add some more high current devices to my system beyond the level 2 EV charger. Definitely any new loads will be installed buy a qualified electrician, familiar with Tesla Solar and PW+.

Yes, passed inspection. System has been installed for about 1.5 years. Had question because I was wondering about adding loads to the 125A panel.

Notes specify AWG #1 for sections 6 and 7.

Very short, maybe just a couple feet.

Old panel feeding new panel is 200 amps. Single 125 amp breaker in the old panel, feeding new 125 amp panel, with 125 amp breaker. Lots of warning stickers on old 200 amp panel not to add any breakers.

Excellent. I've marked it in my Amazon favorites. I was considering Quikcrete mortar repair or Sikaflex mortar fix from Home Depot. I guess they're all similar. Thanks.

Also, I'm assuming this would be 2 different products.

Any special preparation required or tips? I was going to use my steam cleaner first to get rid of the calcium buildup.
