So I recently picked up a used Powerwall 2 and Gateway 2 for a great price. My overall goal is to install it onto my existing 12kw solar array setup grid-tied system.
But first, the PW2 I picked up has not been plugged in for some time, unknown how long. I am fully prepared for it to be bricked - as I have read about here. But figured I would give it a shot. Before I do a full install into my 200 amp load center and rewire/permit/etc. I would like to read the current SOC from the Gateway, and try to trickle charge to see if it will take charge. Is there an optimal way to accomplish this?
I know I can wake the Gateway up with a 12v on the "jump" leads without hooking it up to power, is this sufficient to get info from the PW2? If the PW2 is at 0% SOC is there a way to trickle charge it via the internal panelboard and hook it up to a few solar panels?
I have seen the Mobile Powerwall Setup video, but does someone have a wiring diagram of this setup? Do they utilize the Gateway 2 internal Panelboard for solar input as well as putting a load (the light) on the setup?
Or would it ultimately be easier to just install it as a standard system and roll the dice that it may not take a charge? If the PW2 won't charge or communicate it is ok to leave the Gateway 2 hooked up without a powerwall?
Any thoughts are helpful. I have wired/permitted/signed off my house fully on my own, as well my solar setup. So I am well-versed in codes, system design, and wiring. But new to ESS - and seems relatively straightforward besides the system registration on the Tesla side to add it to my app.
