From The Limiting Factor.
It’s been 6 years since I started the channel and 5 years since Battery Day, and Tesla has now finally and officially cracked the fully dry 4680 production process. In this video I’ll also cover Tesla’s Q4 2025 earnings call.

These are the part of my system I purchased from Signature Solar:
-EG4 6000XP Off-Grid Inverter (I use this for my grid-tied solar system with battery backup)
-SnapNrack | TopSpeed™ | Solar Panel Roof Mount Kit (you can also get a skirt)
-SnapNrack, GROUNDING LUG
-PV 2 Wire Management Clip
-10 AWG Copper PV Wire | Black and Red
-Staubli | 20A | 1000V | In-line Fuse with MC4 Connectors (your amps may vary)
-I cobbled together the cheapest solar and batteries from other sites. I expected it to save me money, but it ended up costing more for integration and I lost some functionality. If I did it again, I’d just by everything from Signature Solar in a package – they have kits with the batteries, inverter, and panels.
