Will the Rich Solar MEGA 100 FLEX work with the Goal Zero Yeti 200X?
Yes, with a catch. Fine in mild weather (20.4V), but on a 20°F (-7°C) morning the open-circuit voltage rises to about 22.3V, above the 22V limit. Cold makes panels push more voltage. Two panels: works, with a catch (2 panels in parallel on 8mm), about 100 W.
Works, with a catch
It charges, but read the note. Best option: 1 panel on 8mm.
- Fine in mild weather (20.4V), but on a 20°F (-7°C) morning the open-circuit voltage rises to about 22.3V, above the 22V limit. Cold makes panels push more voltage.
- The brand does not say whether its voltage limit is open-circuit or working voltage, so we check against the stricter open-circuit number.
- Its AC outlet is modified sine wave, which some devices (and most CPAPs with humidifiers) do not like.
- Needs an MC4 to 8mm adapter cable.

Will the Rich Solar MEGA 100 FLEX work with the Goal Zero Yeti 200X?
Yes, with a catch. Fine in mild weather (20.4V), but on a 20°F (-7°C) morning the open-circuit voltage rises to about 22.3V, above the 22V limit. Cold makes panels push more voltage. Two panels: works, with a catch (2 panels in parallel on 8mm), about 100 W.
Can I connect two MEGA 100 FLEX panels to the Yeti 200X?
Yes, 2 panels in parallel on 8mm. That gives about 100 W, with one catch: Fine in mild weather (20.4V), but on a 20°F (-7°C) morning the open-circuit voltage rises to about 22.3V, above the 22V limit. Cold makes panels push more voltage..
What cable do I need to connect the MEGA 100 FLEX to the Yeti 200X?
Needs an MC4 to 8mm adapter cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One MEGA 100 FLEX goes from 20.4 V on its label to about 22.3 V at 20°F and 23 V at 0°F. The Yeti 200X accepts up to 22 V on the 8mm.
Where to buy

- Goal Zero Yeti 200X: solar input 13 to 22 V on the Solar in (8mm). Goal Zero does not say whether this limit is open-circuit or working voltage, so we use the stricter reading: open-circuit voltage on your coldest morning.
- 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 20.4 V becomes 22.3 V.
- Current over the 7 A cap is safe: the station takes 7 A and you get fewer watts. We count only the capped watts.
- Max 100 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.
