Best Solar Panels for the EcoFlow DELTA Pro 3: Two Ports, Up to 2,070W Verified

For the EcoFlow DELTA Pro 3, a clean setup is four 400W rigid panels: 3 in series on the High-PV port and 1 on the Low-PV port (1,600W). For more, use 8 x 220W NextGen: 6 in series on High-PV and 2 in series on Low-PV (1,760W). Both ports charge at the same time. High-PV takes 30-150V, 15A, 1600W; Low-PV takes 11-60V, 20A, 1000W.

If you want the theory behind the two ports, read our guide to DELTA Pro 3 high-voltage vs low-voltage solar inputs. This page is the shopping list.

Three verified setups

Every string above passed our check: open-circuit voltage at least 5% under the port maximum, current within the port limit, and operating voltage above the port minimum.

Setup A uses the rigid listing neatly, because each pack holds two panels. Setup C has one caution: six 125W panels draw 19.2A, inside Low-PV’s 20A, but with bifacial (back-side) gain the current could reach 20.4A. It passes on EcoFlow’s standard rating; if you want a margin, use five (16A, 625W).

Cables you’ll need

• High-PV: the DELTA Pro 3 manual specifies EcoFlow’s Solar to XT60 Charging cable. EcoFlow doesn’t say whether the XT60i cable that comes with the 220W panel fits this port, so buy the XT60 version. The EcoFlow PH store lists XT60 cables in 3.5 m and 5 m.
• Low-PV: a Solar to XT60i cable. The 220W NextGen includes one. The 400W rigid panels don’t, so buy one for Setup A. The 125W Bifacial includes its own XT60W-to-XT60i cable.
• Series joins: MC4 leads plug male-to-female. Add EcoFlow Solar Extension Cables if the gaps are too long.

Example: solar charge time

Setup A, 1,600W rated:

• Example assumption: panels deliver about 70% of their rating in real Philippine sun.
• 1,600W x 0.7 ≈ 1,120W.
• 4,096Wh ÷ 1,120W ≈ 3.7 hours of strong sun.

Setup B (1,760W) works out to about 3.3 hours, and Setup C (2,070W) about 2.8 hours. With an example 4.5 peak sun hours a day, any of them can refill an empty DELTA Pro 3 in one sunny day. These are estimates, not test results.

Setup steps

1. Place the panels in full sun, clear of shade.
2. Build the High-PV string first: join the panels in series, then connect the end leads to the Solar to XT60 cable and plug it into High-PV.
3. Build the Low-PV group, connect it with the Solar to XT60i cable, and plug it into Low-PV.
4. Check that both inputs show watts on the station’s screen.

A six-panel High-PV string runs well over 100V DC. Keep connectors dry and don’t handle them in the rain. Portable panels on the ground are plug-and-play and you can set them up following the manual. Rigid panels on a roof, or connecting the DELTA Pro 3 to your home’s circuits, need a licensed electrician and an LGU electrical permit.

What to buy

• EcoFlow DELTA Pro 3 on Lazada (EcoFlow PH) or on Shopee
• Setup A: 2 packs of EcoFlow 400W Rigid on Lazada, plus a Solar to XT60 and a Solar to XT60i cable from EcoFlow
• Setup B: 8 x EcoFlow 220W panel on Lazada, plus a Solar to XT60 cable
• Setup C: add 6 x EcoFlow 125W Bifacial on Lazada or on Shopee for Low-PV

Check today’s prices. Adding the EcoFlow DELTA Pro 3 Smart Extra Battery raises storage (up to about 12kWh with two), which makes a bigger solar setup worth it. See how extra batteries change your solar plan.

Bottom line

Use both ports. Four 400W rigid panels (3 + 1) give a tidy 1,600W, eight 220W foldables give 1,760W, and adding six 125W Bifacial panels on Low-PV reaches about 2,070W.
