Solar Panels for the EcoFlow DELTA 3 2000 Air: Using Both 500W Inputs
How to solar-charge the EcoFlow DELTA 3 2000 Air: two 500W inputs, 1000W total. Verified panel setups per port, cable needs, and a charge-time estimate.
Checked against the sources listed below. How we research.
Key takeaways
- The DELTA 3 2000 Air has two XT60i solar inputs, each 12-60V, 15A and 500W, for 1000W total (manual and PH store: "500W*2 1000W Max").
- Treat each port as its own setup: whatever fits one port can be repeated on the other.
- Full 1000W: four 125W bifacial panels in parallel on each port (8 panels).
- Simpler 800W: one 400W Lightweight panel on each port. Never join two 400W Lightweight panels in series (78.6V).
- Best case, 1000W of panels could refill its 1920Wh battery in about 1.9 hours; real conditions take longer.

The EcoFlow DELTA 3 2000 Air takes up to 1000W of solar through two separate 500W inputs. The easiest verified setup is one EcoFlow 400W Lightweight panel per port (800W); to use the full 1000W, put four EcoFlow 125W bifacial panels in parallel on each port.
Two ports, two separate setups
Both XT60i inputs are rated 12-60V, 15A and 500W, and both can work at once. Our checks are per port, so a setup that fits one port can be copied on the second. You don’t have to match them. One port could run a 400W Lightweight panel while the other runs two 220W panels in series.
What you can’t do is pile everything onto one port. Above 500W the extra watts are wasted, and above 60V or 15A you risk damage.
Per-port compatibility
| Panel | Per port | Volts / amps | Usable W per port | Both ports | Cable |
|---|---|---|---|---|---|
| 125W bifacial | 4 in parallel | 50V / 12.8A | 500W | 1000W (8 panels) | XT60W-to-XT60i included |
| 400W Lightweight | 1, single | 39.3V / 12.2A | 400W | 800W (2 panels) | None, built-in XT60 |
| 220W single-face | 2 in series | 43V / 12.4A | 440W | 880W (4 panels) | MC4-to-XT60i included |
| 160W single-face | 2 in series | 42.6V / 9.1A | 320W | 640W (4 panels) | MC4-to-XT60i included |
| 400W rigid | 1, single | 37.1V / 13.79A | 400W | 800W (the 2-panel pack) | Not included: buy 2 Solar-to-XT60i cables |
Combinations that fail on a port: two 400W Lightweight in series (78.6V), two 400W rigid in series (74.2V) or parallel (27.58A), three 220W or 160W in series (64.5V / 63.9V), and two 220W or 160W in parallel (24.8A / 18.2A).
The rigid pack fits this station well
The EcoFlow 400W rigid listing is a pack of two 400W panels. On single-port DELTA 3 models only one of the pair can be used. On the 2000 Air, each panel gets its own port for 800W. The pack includes no cable, so you need two Solar-to-XT60i cables, one per panel. Rigid panels are usually mounted in place; if that means the roof, hire a licensed electrician.
Charging estimate
The 2000 Air holds 1920Wh. Best case, hours ≈ capacity ÷ usable watts:
| Setup | Usable W | Best-case hours |
|---|---|---|
| 8 × 125W bifacial | 1000W | about 1.9 |
| 4 × 220W (2 series per port) | 880W | about 2.2 |
| 2 × 400W Lightweight | 800W | about 2.4 |
Real output is lower in heat, haze and when the sun is low, so treat these as minimums. During rainy season, one port’s worth of panels may only top it up partly.
Setup steps
- Split your panels into two groups that each fit the table above.
- Lay each group in full sun. Connect series or parallel links first, then the cable to the station.
- Plug group one into input 1 and group two into input 2.
- Check that the screen or app shows watts coming in on both.
Portable panels can be set up by the owner using the manuals. A permanent mount on the roof, or any connection to your house wiring or breaker panel, needs a licensed electrician (PEE) and an LGU electrical permit.

Bottom line
Use both inputs. One 400W Lightweight per port gives 800W with the fewest parts; four 125W bifacial per port gives the full 1000W. Keep every port under 60V and 15A.
