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 | C1000 Gen 2 | DELTA 3 Classic | What it means |
|---|---|---|---|
| Capacity | 1,024 Wh | 1,024 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 2,000 W | 1,800 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 24.9 lb | 26.7 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $2,398 | $499 | Vendor list price at the time of collection; street prices move. |
| Cost per watt-hour lower is better | $2.34 | $0.49 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 41.1 Wh/lb | 38.4 Wh/lb | Capacity you get per pound carried. |
| Max solar input | 600 W | 500 W | Caps how large an array is useful, and therefore off-grid recharge speed. |
| AC recharge time lower is better | 49 min | — | Vendor-stated time to full from a wall outlet. |
| Rated cycles | 4,000 cycles | — | Vendor claim for charge cycles before capacity degrades to 80%. |
| UPS switchover lower is better | 10 ms | — | How long the unit takes to switch to battery. Under 20 ms keeps a desktop alive. |
| Warranty | 60 months | 60 months | Stated warranty length from the vendor listing. |
