Will the Renogy E.Flex 200W Portable Solar Panel work with the BLUETTI AC2A?
Yes. One Renogy E.Flex 200W Portable Solar Panel works with the BLUETTI AC2A: about 25.6 V on a 20°F morning against the station's 28 V limit, and about 165 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 165 W.
Works
1 x E.Flex 200W Portable Solar Panel into the AC2A (1 panel on Solar input) stays inside 12 to 28 V, even at 20F. The station caps the current at 8.2 A.
- The panels can push 9.9A but this input takes 8.2A, so the station caps it. Safe, you just lose some watts.
- Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the Renogy E.Flex 200W Portable Solar Panel work with the BLUETTI AC2A?
Yes. One Renogy E.Flex 200W Portable Solar Panel works with the BLUETTI AC2A: about 25.6 V on a 20°F morning against the station's 28 V limit, and about 165 W in full sun. Two panels: works (2 panels in parallel on Solar input), about 165 W.
Can I connect two E.Flex 200W Portable Solar Panel panels to the AC2A?
Yes, 2 panels in parallel on Solar input. That gives about 165 W.
What cable do I need to connect the E.Flex 200W Portable Solar Panel to the AC2A?
Use the solar charging cable that came with the station (MC4 on the panel side).
Is it safe on a cold morning?
Panel voltage rises in the cold. One E.Flex 200W Portable Solar Panel goes from 23.4 V on its label to about 25.6 V at 20°F and 26.4 V at 0°F. The AC2A accepts up to 28 V on the Solar input.

Other panels that work with the AC2A
- BLUETTI AC2A: solar input 12 to 28 V on the Solar in (Solar input). BLUETTI sets this limit on open-circuit voltage (Voc), so we hold the panels' Voc on your coldest morning to it.
- Cold raises panel voltage: we add 0.30% per °C below 77F (25°C), a typical figure, since this panel does not publish its own. At 20F one panel's 23.4 V becomes 25.6 V.
- Current over the 8.2 A cap is safe: the station takes 8.2 A and you get fewer watts. We count only the capped watts.
- Max 200 W on this input.
- Cold-morning voltage uses 0.30% per °C, typical for crystalline panels. This panel's own value is not published.
- Expected watts are the best case in full sun. Real-world midday output is usually 60 to 80% of that.
