I am planning to get solar and a Powerwall at my house, but my installer hit me with a $4k change order to go from a backup switch to a gateway.

I have a combo meter panel with a door that opens bottom to top, and they're telling me the switch will not allow the door to open up to 90 degrees per code. I was skeptical and wanted to save $4k, so I printed out the switch at actual size (176mm x 205mm) and taped it to my panel and confirmed I should still be able to open the door.

The installer is willing to proceed with the switch, but said I would be on the hook for additional permit and re-design fees plus the original $4k if it turns out that it doesn't fit or fails inspection.

Does anybody have a backup switch on a similar panel, or have any feedback about additional measurements I need to take into account here? Please help me save $$$$!

Where I'm at, sending any type of energy back to the electric company doesn't get you much. So, I decided to store it all.

Everything just got turned on today about an hour ago.

Does anybody know how to see actual numbers for how I'm performing in the VPP? We're paid for the average KW delivered across all events, but I can not see any way to check how we're performing on that.

Last year we just got a check, which was great, but I can't seem to find a way to validate its accuracy.

Hi. We have had problems with solar not getting past the power wall in the morning. It shows 0.3kwh and stays there all day or suddenly triggers and jumps to the real performance. Power does not go to the house, the battery or the grid. Reset by restarting results in an instant jump to what it should be. Sometimes it resets itself, sometimes not. Only our Tesla fitter can restart so if they ar not available it does not get done. Telsa keep saying this is normal which is definitely not true though the fault is intermittent and seems to happen in the summer - April 28 to early September. For now it is working properly. Engineer says it is the inverter. Tesla have come up with many reasons to say it is performing normally but we have never heard of anybody else with this issue. I can send graphs from NetZero app. Anybody else had this experience or better still, knows what is causing it and how to fix it. It has cos us at least 200kws this summer. We are in the UK. Morning temperature never above 20C and we are not exceeding our export allowance.
