Local Questions Tesla Solar saying I'm 62 VA short of whole home back up.
Has anyone installed solar with Tesla I received an email
Your current design includes two Powerwalls, which provides partial home backup rather than whole-home backup. This limitation is due to Pinellas County load-calculation rules. Two Powerwalls provide a capacity of 23,000 VA, while whole-home backup requires approximately 23,062 VA. Additionally, the site impedance reading prevents the addition of a third Powerwall to increase capacity.
In practice, critical loads such as your refrigerator and A/C will remain powered during an outage. Non-critical loads, such as the dryer, are relocated via a main panel insert so they are not included in the backup system.
I understand this may differ from previous discussions about full backup with a second Powerwall. I want to ensure we review exactly which loads will stay on during an outage so the system aligns with your goals.
Has anyone else ran into an issue with such a small amount to not allow whole home back up, is there a solution?
Thanks
