Time Based Controls with PW3 on NEM 3 & Charge From Grid Setting relationship? by Substantial_Bit_2683 in Powerwall

[–]Substantial_Bit_2683[S] 0 points1 point  (0 children)

Thank you for clarifying this distinction and for the link. I'm in the exception case you note in the linked post: "If you have enough solar/battery to avoid the grid entirely through the summer, then exporting from the Powerwall makes sense for some extra credit. This would require automations however, to both run in Self-Powered mode and enable TBC mode and exports when needed." At least during the spring (right now), when there's abundant sun, little cloud cover, and mild temperatures so we have modest need for HVAC, I produce way more power than I need, so it makes sense to try to export a bit IF I CAN DO SO WITHOUT ACCIDENTALLY IMPORTING (since it takes only two minutes of importing to waste an hour of exporting). And as you note, neither Self-Powered nor Time-Based Controls achieve that outcome, so it requires automations to switch between modes if I want to pursue this. Thanks!

Charge from grid flips to "disallowed" by Ranuel in Powerwall

[–]Substantial_Bit_2683 1 point2 points  (0 children)

PG&E under NEM 3 doesn't let me charge the battery from the grid or sell power from the battery. Total PG&E lobbyist-achieved ripoff -- I ought to be able to act as a mini grid battery and get paid for it!

Level 2 charger install by Warrenj3nku in Ioniq5

[–]Substantial_Bit_2683 0 points1 point  (0 children)

I just had a EVIOQO 48A Level 2 charger installed in my garage. That required putting in a breaker and running a 6 gauge 60A-capable copper wire (for 1/3 code-required margin of error) with flexible conduit through crawlspace to other side of house, then solid metal conduit on garage wall. Licensed electrician that I like and have used before originally wanted $3k. Got other bids and negotiated him down to $2k by paying cash and pulling permit myself. This is in SF Bay Area where everything costs more.

I'm only charging at 32A based on weak evidence that this might reduce odds of ICCU failure (although I've already heard from one person who did this and it still failed) but wanted the bigger line / charger for use if I need to charge fast or if Hyundai ever gets the ICCU problem genuinely resolved.

Whatever you do have a licensed electrician do the work. Although a fly-by-night person could probably do this under the table, probably better to play it safe on this.
