Spec by spec
A green arrow marks the better figure on each row. Rows where only one unit publishes a number are shown without a winner rather than guessed.
| Metric | DELTA 3 Ultra | Yeti 3000X | What it means |
|---|---|---|---|
| Capacity | 3,072 Wh | 3,032 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 3,600 W | 2,000 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 72.1 lb | 69.8 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $1,399 | $3,000 | Vendor list price at the time of collection; street prices move. |
| Cost per watt-hour lower is better | $0.46 | $0.99 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 42.6 Wh/lb | 43.4 Wh/lb | Capacity you get per pound carried. |
| Max solar input | 3,200 W | 600 W | Caps how large an array is useful, and therefore off-grid recharge speed. |
| AC recharge time lower is better | — | 840 min | Vendor-stated time to full from a wall outlet. |
| Rated cycles | — | 500 cycles | Vendor claim for charge cycles before capacity degrades to 80%. |
| Warranty | 60 months | 24 months | Stated warranty length from the vendor listing. |
