Will the Rich Solar MEGA 100 FLEX work with the BLUETTI Apex 300?
Yes. One Rich Solar MEGA 100 FLEX works with the BLUETTI Apex 300: about 22.3 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (1 panel on Solar input + 1 panel on Solar input), about 200 W.
Works
1 x MEGA 100 FLEX into the Apex 300 (1 panel on Solar input) stays inside 12 to 60 V and under 20 A, even at 20F.
- Use the solar charging cable that came with the station (MC4 on the panel side).

Quick answers
Will the Rich Solar MEGA 100 FLEX work with the BLUETTI Apex 300?
Yes. One Rich Solar MEGA 100 FLEX works with the BLUETTI Apex 300: about 22.3 V on a 20°F morning against the station's 60 V limit, and about 100 W in full sun. Two panels: works (1 panel on Solar input + 1 panel on Solar input), about 200 W.
Can I connect two MEGA 100 FLEX panels to the Apex 300?
Yes, 1 panel on Solar input + 1 panel on Solar input. That gives about 200 W.
What cable do I need to connect the MEGA 100 FLEX to the Apex 300?
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 FLEX goes from 20.4 V on its label to about 22.3 V at 20°F and 23 V at 0°F. The Apex 300 accepts up to 60 V on the Solar input.

Other panels that work with the Apex 300
- BLUETTI Apex 300: solar input 12 to 60 V on the Solar in 1 (Solar input). BLUETTI 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 20.4 V becomes 22.3 V.
- Current over the 20 A cap is safe: the station takes 20 A and you get fewer watts. We count only the capped watts.
- Max 1,200 W on this input, 2,400 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.
