|---|---|
| Usable energy | 1741Wh (85% via AC outlets) |
| Continuous AC output | 2400W |
| Surge rating | 4800W |
| Gas furnace blower running watts | 600W |
| Startup watts | 1500W |
| Average draw | 300W |
| Estimated runtime | 5.8 hours |
| Energy per day of typical use | 7.2 kWh |
2048Wh × 0.85 = 1741Wh usable ÷ 300W average = 5.8 hours

Recharging with solar
The EcoFlow Delta 2 Max accepts up to 1000W of solar input. In real conditions that harvests about 3.8 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A gas furnace blower uses about 7.2 kWh a day at 24 hours of use, more than the EcoFlow Delta 2 Max’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- A gas furnace still needs electricity for its blower and igniter. Connecting one requires a transfer switch or an inlet installed by an electrician.
- You’ll still have about 1800W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow Delta 2 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
