I'm in a unique situation where I have the opportunity to have a 3rd Powerwall installed on my whole house backup for ~$4400 which would be ~$3300 after ITC.
I'm already a net producer so I only get reimbursed ~$0.03/kWh at True-Up. The ROI for any additional surplus doesn't justify the cost.
I do live in an area of frequent PSPSs and power outages. The extra Powerwall would allow me to run the AC a little further into the evening during a summer outage. The additional Powerwall would have some benefit during a winter outage depending on the weather and the ability of my ~10 KW solar system's ability to recharge it.
My main concern is what is going to happen the future. I'm currently on NEM 2 which is currently set to expire in 2029. However, if NEM 3 goes through the way it was previously proposed it would expire in 2024. Depending on what the CPUC does with NEM 3 and the rates, an additional Powerwall could be a significant advantage.
Looking for opinions and reasons on whether or not I should proceed with getting a 3rd Powerwall installed.
