We just got a confirmed installation date of Jan 3. Getting two Powerwalls installed in conjunction with an existing 10.395 kW solar setup. We are allowed to keep our net metering.

They want to reevaluate the interconnect. More powerwalls = more power flow to/from the grid, and they need to make sure your transformer, etc are size appropriately.but you have to get yet another approval from the electrical company that serves your area (makes absolutely 0 sense to me, since Powerwalls are plug-and-play and chained, so you don't even have to touch electric wiring at all). And it's usually a major pain.
Powerwalls by themselves don't produce energy, they just store it. So you might be able to output more energy to the grid in the short period of time, but total amount of energy output stays unchanged. And even that isn't going to happen, since Powerwalls don't usually dump energy into the grid, they charge up, and once they are full, they redirect energy output from the solar array into the grid. Also, since Tesla doesn't usually connect Powerwalls to the grid directly (as an input), the amount of electricity from the grid stays unchanged (Tesla usually connects Powerwalls to be chargeable only from the solar panels, that's a prerequisite for getting federal tax break). So overall, unless you add more panels, you input/output from the grid should stay more or less unchanged (it should be slightly lower then before due to the loss of efficiency from DC to AC conversion). But when did common sense every stopped companies from creating more regulations?They want to reevaluate the interconnect.
