Will the Rich Solar MEGA 100 work with the BLUETTI EP500?
No. Open-circuit voltage 22.8V is below the 55V minimum for this input, so it will not start charging. Two panels: don't connect (2 panels in parallel on PV input), about 0 W.

Quick answers
Will the Rich Solar MEGA 100 work with the BLUETTI EP500?
No. Open-circuit voltage 22.8V is below the 55V minimum for this input, so it will not start charging. Two panels: don't connect (2 panels in parallel on PV input), about 0 W.
Can I connect two MEGA 100 panels to the EP500?
No: Open-circuit voltage 22.8V is below the 55V minimum for this input, so it will not start charging.
Is it safe on a cold morning?
Panel voltage rises in the cold. One MEGA 100 goes from 22.8 V on its label to about 25 V at 20°F and 25.7 V at 0°F. The EP500 accepts up to 145 V on the PV input.
Where to buy

- BLUETTI EP500: solar input 55 to 145 V on the Solar in (PV 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 22.8 V becomes 25 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.
- 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.
