Will the Rich Solar MEGA 100 SLIM work with the EcoFlow DELTA mini?

Yes. One Rich Solar MEGA 100 SLIM works with the EcoFlow DELTA mini: about 25.8 V on a 20°F morning against the station's 75 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on Solar input), about 200 W.

Verdict

Works

1 x MEGA 100 SLIM into the DELTA mini (1 panel on Solar input) stays inside 11 to 75 V and under 10 A, even at 20F.

The panels can push 10.2A but this input takes 10A, so the station caps it. Safe, you just lose some watts.

Quick answers

Will the Rich Solar MEGA 100 SLIM work with the EcoFlow DELTA mini?

Yes. One Rich Solar MEGA 100 SLIM works with the EcoFlow DELTA mini: about 25.8 V on a 20°F morning against the station's 75 V limit, and about 100 W in full sun. Two panels: works (2 panels in series on Solar input), about 200 W.

Can I connect two MEGA 100 SLIM panels to the DELTA mini?

Yes, 2 panels in series on Solar input. That gives about 200 W.

What cable do I need to connect the MEGA 100 SLIM to the DELTA mini?

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 MEGA 100 SLIM goes from 23.6 V on its label to about 25.8 V at 20°F and 26.6 V at 0°F. The DELTA mini accepts up to 75 V on the Solar input.

Rules we applied
  • EcoFlow DELTA mini: solar input 11 to 75 V on the Solar in (Solar input). EcoFlow 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 23.6 V becomes 25.8 V.
  • Current over the 10 A cap is safe: the station takes 10 A and you get fewer watts. We count only the capped watts.
  • Max 300 W on this input.
Assumptions
  • 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.
