Pros
- Built-in solar inverter (97.5% round-trip efficiency) — no separate inverter needed if pairing with solar
- 11.5kW continuous output is enough to start most single large loads, including a 5-ton AC unit
- Up to 4 units can be stacked for 54kWh of total whole-home capacity
- 10-year warranty guaranteeing at least 70% capacity retention
Cons
- Not sold on Amazon — purchased and installed only through Tesla or a certified installer, so pricing isn't a simple checkout total
- Installed cost ($13,500-$16,800 per industry cost guides) is the highest of the whole-home options on this page before incentives
- Requires Tesla-certified installation — not a DIY or general-electrician product
