Spec by spec
A green mark is the better published figure on that row. Blank cells mean the vendor did not publish the number — we do not estimate.
| Metric | R2500 V2 | DELTA 3 Max | What it means |
|---|---|---|---|
| Capacity | 1,920 Wh | 2,048 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 2,500 W | 2,400 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 63.9 lb | 44.8 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $640 | $1,199 | Hub catalogue list price (same figure as product pages). Historical lows stay off this column. |
| Cost per watt-hour lower is better | $0.33 | $0.59 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 30.0 Wh/lb | 45.7 Wh/lb | Capacity you get per pound carried. |
| Max solar input | 1,000 W | 500 W | Caps how large an array is useful, and therefore off-grid recharge speed. |
| AC recharge time lower is better | 97 min | — | Vendor-stated time to full from a wall outlet. |
| Rated cycles | 3,500 cycles | — | Vendor claim for charge cycles before capacity degrades to 80%. |
| UPS switchover lower is better | 15 ms | 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. |
