Will the Rich Solar MEGA 100 SLIM work with the Goal Zero Yeti 1500X?
Yes. One Rich Solar MEGA 100 SLIM works with the Goal Zero Yeti 1500X: about 25.8 V on a 20°F morning against the station's 50 V limit, and about 100 W in full sun. Two panels: works (1 panel on High Power Port + 1 panel on 8mm), about 200 W.
Works
1 x MEGA 100 SLIM into the Yeti 1500X (1 panel on High Power Port) stays inside 14 to 50 V and under 50 A, even at 20F.
- The brand does not say whether its voltage limit is open-circuit or working voltage, so we check against the stricter open-circuit number.
- Goal Zero gives solar charging as 600 W actual input at most, across its ports.
- Needs an MC4 to HPP (Anderson Powerpole) adapter cable.

Quick answers
Will the Rich Solar MEGA 100 SLIM work with the Goal Zero Yeti 1500X?
Yes. One Rich Solar MEGA 100 SLIM works with the Goal Zero Yeti 1500X: about 25.8 V on a 20°F morning against the station's 50 V limit, and about 100 W in full sun. Two panels: works (1 panel on High Power Port + 1 panel on 8mm), about 200 W.
Can I connect two MEGA 100 SLIM panels to the Yeti 1500X?
Yes, 1 panel on High Power Port + 1 panel on 8mm. That gives about 200 W.
What cable do I need to connect the MEGA 100 SLIM to the Yeti 1500X?
Needs an MC4 to HPP (Anderson Powerpole) adapter 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 Yeti 1500X accepts up to 50 V on the High Power Port.

Other panels that work with the Yeti 1500X
- Goal Zero Yeti 1500X: solar input 14 to 50 V on the Solar in 1 (High Power Port). 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 23.6 V becomes 25.8 V.
- Current over the 50 A cap is safe: the station takes 50 A and you get fewer watts. We count only the capped watts.
- Max 600 W on this input, 600 W across all inputs.
- 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.
