Will the Rich Solar MEGA 50 work with the EcoFlow TRAIL 300 DC?
Yes. One Rich Solar MEGA 50 works with the EcoFlow TRAIL 300 DC: about 22.8 V on a 20°F morning against the station's 30 V limit, and about 50 W in full sun. Two panels: works (2 panels in parallel on Solar/Car input (XT60)), about 100 W.
Works
1 x MEGA 50 into the TRAIL 300 DC (1 panel on Solar/Car input (XT60)) stays inside 10 to 30 V and under 10 A, even at 20F.
- Keep the panel under 30 V: EcoFlow says a higher voltage can damage the station.
- Use an MC4 to XT60 solar cable.

Quick answers
Will the Rich Solar MEGA 50 work with the EcoFlow TRAIL 300 DC?
Yes. One Rich Solar MEGA 50 works with the EcoFlow TRAIL 300 DC: about 22.8 V on a 20°F morning against the station's 30 V limit, and about 50 W in full sun. Two panels: works (2 panels in parallel on Solar/Car input (XT60)), about 100 W.
Can I connect two MEGA 50 panels to the TRAIL 300 DC?
Yes, 2 panels in parallel on Solar/Car input (XT60). That gives about 100 W.
What cable do I need to connect the MEGA 50 to the TRAIL 300 DC?
Use an MC4 to XT60 solar cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One MEGA 50 goes from 20.8 V on its label to about 22.8 V at 20°F and 23.5 V at 0°F. The TRAIL 300 DC accepts up to 30 V on the Solar/Car input (XT60).

Other panels that work with the TRAIL 300 DC
- EcoFlow TRAIL 300 DC: solar input 10 to 30 V on the Solar in (Solar/Car input (XT60)). 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 20.8 V becomes 22.8 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 110 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.
