Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the BLUETTI AC70?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the BLUETTI AC70: about 44.7 V on a 20°F morning against the station's 58 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on XT60 (XT60PM-M)), about 342 W.
Works
1 x MEGA 200 PRO FLEX (24V) into the AC70 (1 panel on XT60 (XT60PM-M)) stays inside 12 to 58 V and under 10 A, even at 20F.
- BLUETTI's manual: do not use panels above 58V open-circuit voltage. That is lower than the 60V limit on the AC180.
- Do not mix different types of panels, and use at least 100W of panels.
- With 500W of sun the AC70 is full in about 2 hours and stops charging. That is normal, not a fault.
- A 24 V panel: 40.8 V open circuit on its own, so two in series only suit high-voltage solar inputs.
- Use an MC4 to XT60 solar cable.

| Wiring | Input | Volts at 20F | Amps | Watts | Verdict |
|---|---|---|---|---|---|
| 2 panels in parallel on XT60 (XT60PM-M) The panels can push 11.7A but this input takes 10A, so the station caps it. Safe, you just lose some watts. | XT60 (XT60PM-M) | 44.7 | 11.7 | 342 | Works |
| 2 panels in series on XT60 (XT60PM-M) Open-circuit voltage 81.6V is above the station's 58V limit. Going over a station's input voltage limit can damage it. | XT60 (XT60PM-M) | 89.4 | 5.9 | 0 | Don't connect |
Quick answers
Will the Rich Solar MEGA 200 PRO FLEX (24V) work with the BLUETTI AC70?
Yes. One Rich Solar MEGA 200 PRO FLEX (24V) works with the BLUETTI AC70: about 44.7 V on a 20°F morning against the station's 58 V limit, and about 200 W in full sun. Two panels: works (2 panels in parallel on XT60 (XT60PM-M)), about 342 W.
Can I connect two MEGA 200 PRO FLEX (24V) panels to the AC70?
Yes, 2 panels in parallel on XT60 (XT60PM-M). That gives about 342 W.
What cable do I need to connect the MEGA 200 PRO FLEX (24V) to the AC70?
Use an MC4 to XT60 solar cable.
Is it safe on a cold morning?
Panel voltage rises in the cold. One MEGA 200 PRO FLEX (24V) goes from 40.8 V on its label to about 44.7 V at 20°F and 46 V at 0°F. The AC70 accepts up to 58 V on the XT60 (XT60PM-M).

Other panels that work with the AC70
- BLUETTI AC70: solar input 12 to 58 V on the Solar in (XT60 (XT60PM-M)). 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 40.8 V becomes 44.7 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 500 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.
