I’m in a similar boat - 2018 RWD Long Range with FSD. Back in December I had the HW3 retrofit installed (previously was using original HW2 hardware) and have seen the cabin error fairly consistently on every drive even when not using FSD. Just got the FSD 12 update on 3/24 and have not seen it...

Just to close the loop on this with some empirical evidence, the consensus is correct; without AC power to the gateway (via grid or the Powerwalls), the Powerwalls will shut down. I used the "Go off-grid" option in the Tesla app to disconnect the grid, then flipped the main breaker between my...

Ah, those are the Powerwall breakers themselves - mine are located (temporarily) in my main loads panel. My Gateway does not have the optional internal panelboard which yours does.

What do you mean by "gateway breaker?" There isn't anything physically between the Powerwall and the home loads. Though presumably you mean without a signal over the gateway communication cable they shutdown for safety. I'll have to consider if there is an alternative way to minimize downtime.

Are Powerwalls able to function/provide backup power without a connected gateway? I am having my Gateway 2 relocated from an interior garage wall to the exterior side of the same wall, and ideally would like my Powerwalls to continue providing power while the electrician disconnects, moves, and...

@andy92782 For what it's worth I have a similar NEM 2.0 application inflight that was just approved by SCE this week! 04/12/2023: NEM 2.0 application signed and submitted to SCE 05/02/2023: SCE "We appreciate your patience" email indicating things are still processing and taking 30+ business...

Okay I think this makes sense. I assume it remains true even if there is a service disconnect breaker between the meter and the Gateway? I guess this is the confusing part as the answer is basically “that section of code doesn’t apply to the Gateway for ‘reasons.’” I’m worried AHJ would not...

I've been researching electrical line diagrams for a 10kW solar system with 2x Powerwalls and how to incorporate that with 200amp service without derating a main breaker or doing a line-side tap for solar. There's a lot of information and references to bus rating requirements in NEC...
