EcoFlow DELTA 3 Plus with the EcoFlow 45W Portable
Unverified
This page is excluded from search: No verified way to connect this panel to this station.
The EcoFlow 45W Portable has a DC5521 output, so it can’t be wired in series or parallel from its own leads. We evaluate one panel per port.
We have no verified cable from the panel’s DC5521 output to a XT60i port.
Thick mark: cold Voc · Thin mark: operating Vmp, 21.9 V
3 caveats
- The maker publishes no temperature coefficient, so cold voltage uses our conservative −0.40 %/°C.
- The 15 A limit comes from a secondary source, not the maker’s page.
- The connector type comes from a secondary source, so check the physical port.

Can I connect the EcoFlow 45W Portable to the EcoFlow DELTA 3 Plus?
Not with parts we can verify. The EcoFlow 45W Portable has a DC5521 output and we found no verified cable to the EcoFlow DELTA 3 Plus’s XT60i input. The 11 to 60 V limits don’t matter until there’s a safe connection, so choose a different panel.
What is the best way to wire EcoFlow 45W Portable panels to the EcoFlow DELTA 3 Plus?
We can’t recommend a wiring layout for this pair. We tested every series and parallel combination the panel’s leads allow, across 2 ports and four temperature bands, and none passed every check. The table below shows the exact limit each layout hits, so you can compare another panel.
| Port | Layout | Voc 25 °C | Voc 0 °C | Voc −10 °C | Voc −20 °C | Vmp | Isc | Watts | Verdict at −10 °C |
|---|---|---|---|---|---|---|---|---|---|
| Solar Charging input 1 | 1S1P | 25.6 | 28.2 | 29.2 | 30.2 | 21.9 | 2.1 | 44 | Unverified |
| Solar Charging input 2 | 1S1P | 25.6 | 28.2 | 29.2 | 30.2 | 21.9 | 2.1 | 44 | Unverified |
How cold can it get before this string overvolts the EcoFlow DELTA 3 Plus?
Cold doesn’t change the answer for this pair within our −25 °C test range. Using our assumed −0.40 %/°C (no figure is published), each EcoFlow 45W Portable panel rises from 25.6 V at 25 °C to 30.7 V at −25 °C, and that stays inside the 60 V limit of Solar Charging input 1.
The cold-weather correction is the same one NEC Article 690.7 requires for PV system voltage.
Which cable connects the EcoFlow 45W Portable to the EcoFlow DELTA 3 Plus?
No cable makes this pair worth buying yet. We have no verified adapter or no working layout for the EcoFlow 45W Portable on the EcoFlow DELTA 3 Plus, so we aren’t recommending parts. Check the port labels on your own unit, and compare the 11 to 60 V input window against your panel’s label.
How long does the EcoFlow 45W Portable take to recharge the EcoFlow DELTA 3 Plus?
We can’t give a recharge time for this pair because no verified layout works. For comparison, the EcoFlow DELTA 3 Plus stores 1,024 Wh, so any panel needs to deliver real power to its 11 to 60 V input before the sun-hour maths means anything at all.
Where do these EcoFlow DELTA 3 Plus and EcoFlow 45W Portable numbers come from?
Station limits come from us.ecoflow.com and panel ratings from us.ecoflow.com, each checked against a verbatim quote on that page. Panels must also pass a physics test: Vmp times Imp must land within 15% of rated watts. Anything failing goes to quarantine and gets no page.
