Will the Rich Solar MEGA 100 SLIM work with the EcoFlow DELTA 3 Max?

Yes. One Rich Solar MEGA 100 SLIM works with the EcoFlow DELTA 3 Max: about 25.8 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar/Car input (XT60i)), about 200 W.

Verdict

Works

1 x MEGA 100 SLIM into the DELTA 3 Max (1 panel on Solar/Car input (XT60i)) stays inside 11 to 60 V and under 13 A, even at 20F.

Quick answers

Will the Rich Solar MEGA 100 SLIM work with the EcoFlow DELTA 3 Max?

Yes. One Rich Solar MEGA 100 SLIM works with the EcoFlow DELTA 3 Max: about 25.8 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (2 panels in parallel on Solar/Car input (XT60i)), about 200 W.

Can I connect two MEGA 100 SLIM panels to the DELTA 3 Max?

Yes, 2 panels in parallel on Solar/Car input (XT60i). That gives about 200 W.

What cable do I need to connect the MEGA 100 SLIM to the DELTA 3 Max?

Use an MC4 to XT60i solar cable.

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 3 Max accepts up to 60 V on the Solar/Car input (XT60i).

Rules we applied
  • EcoFlow DELTA 3 Max: solar input 11 to 60 V on the Solar in (Solar/Car input (XT60i)). 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 13 A cap is safe: the station takes 13 A and you get fewer watts. We count only the capped watts.
  • Max 500 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.
