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 | DELTA Pro 3 | E3800LFP | What it means |
|---|---|---|---|
| Capacity | 4,096 Wh | 3,840 Wh | How much energy the unit stores. Sets how long everything else can run. |
| Continuous AC output | 4,000 W | 4,200 W | The largest load the inverter will run continuously, not counting surge. |
| Weight lower is better | 113.5 lb | 87.3 lb | The spec buyers most often regret ignoring. |
| List price lower is better | $3,699 | $1,299 | Hub catalogue list price (same figure as product pages). Historical lows stay off this column. |
| Cost per watt-hour lower is better | $0.90 | $0.34 | Price divided by capacity. The fairest single value metric. |
| Watt-hours per pound | 36.1 Wh/lb | 44.0 Wh/lb | Capacity you get per pound carried. |
| Max solar input | 2,600 W | 3,000 W | Caps how large an array is useful, and therefore off-grid recharge speed. |
| Rated cycles | 4,000 cycles | 3,500 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. |
| Max expandable capacity | 48,000 Wh | 26,880 Wh | How far the system can grow with add-on batteries. |
| Warranty | 60 months | 60 months | Stated warranty length from the vendor listing. |
