I just got two Tesla Powerwalls installed with Backup Gateway 2 yesterday. It's a whole-house backup configuration and I don't have solar.
I have an A/C and the compressor outside has a label that says 19.9 RLA and 109 LRA. I thought this required a SureStart for the AC to work during power outage, but the installer said I may not need it. He said try it out once the batteries are fully charged and if it doesn't work, he will have someone come install it. I was very skeptical.
I just shut off the circuit breaker from the grid with the two batteries at 95% charged. To my surprise, when I turned on the AC, it was working! The fan on the compressor outside was spinning and it felt like cold air was coming out of the vents. The house power usage on the Tesla app jumped from 0.5kW to 4kW, so I assume the AC was actually running. Am I testing this right? Is it possible to run AC with 109 LRA without SureStart? Thank you.
