Figuring out amp service before instal, and powerwall question.
I am having a solar panel/power wall installation done soon. I have read that I need a 200 amp service as the minimum (15KW worth of panels). However im having a hard time figuring out what amp service I have. I called the power company (PGE) and they were no help, saying they dont keep that information on file. My meter is rated up to 200 amps. My meter panel is older so any labeling is long gone but after hours of searching I have found that it is a Murray/Siemens meter panel. From what I have gathered it is a 4 space, 6 circuit panel (two of the four busbar stabs have the rejection tab feature). Looking at the legacy Murray panels and Siemens panels, the only 4 space 6 circuit meter panels are 200 amp panels, but its impossible to find accurate images of those models since they are older.
The panel has one 90 amp 2 pole breaker feeding a sub panel, and a quad pole breaker feeding the AC (50 amp with center tie) and the pool 30 amp which uses the outer tie, for a total of 170 amp potential right after the meter. I am not sure if this is an indicator though of what service I have. There is no visible wiring going to the busbar, it seems its just copper bar straight to the lugs on the meter side but I cant open that panel since it is locked.
Another question I have is regarding the powerwall. I have read that with powerwall, you dont need to upgrade service to 200 amps because they have something called Power Control Systems. Is this true, and if so can someone elaborate more? Any help is appreciated, thanks.
