All,
Long time TMC member but this is the first time I have ever ventured into the Tesla Energy thread. Been reading about the horror stories coming out of Texas due to the lack of power. I checked the Tesla website and the Powerwall FAQ states that a single Powerwall will only support the following loads, and note that A/C is not on the included list:
The home where we would possibly be installing this is a bit of a special case. When we installed our SPV array back in 2016, we sized it to be more than 2x the amount of power we would use on average. With our current SCE power plan, we are fully net metered, our monthly bill is $12, and once a year we get a check for $60 from SCE during our "true up". So the Powerwall wouldn't provide any benefit from a cost savings standpoint given the net metering situation, it would only be required in case of power loss.
My question is basically, can the Powerwall also support our A/C unit should there be a power outage during the hottest summer months? Not sure if the loads supported by the Powerwall are only on specific dedicated circuits, or whether the Powerwall feeds the entire house, and you need to scale back the consumption manually. I suspect the former.
The reason I think that the A/C might be able to be included is that the total power draw might not be that large, but it may be an issue of instantaneous draw. Not sure what the tonnage of the A/C unit is but I can find that out if needed. The home is 2 miles from the ocean in Southern California, and is only 1,100 square feet. The A/C is typically only used about 10 days per year due to the ocean breeze keeping things relatively cool even in summer. See below for the home energy usage from the hottest month of 2020.
I suspect that we will get the Powerwall in any case, just wondering about the A/C question since an elderly family member resides in the home currently. Having the A/C available during an outage would be icing on the cake.
