The 400W Rigid Solar Panel in brief

Carrying 48.1 lb comes with the EcoFlow 400W Rigid Solar Panel, which also brings 23% efficiency, IP68 and 400 W at 31 V. Open-circuit voltage of 37.1 V rises to 41.6 V at 14°F, so one panel is the limit on a 60 V Jackery input such as the Explorer 2000 Plus, using an MC4 to DC8020 cable. Stations with 20 V to 30 V inputs, including the EcoFlow RIVER 2 and BLUETTI EB3A, are outside the limits. In all, 65 of the 78 stations are inside.

FAQ

Can two EcoFlow 400W Rigid panels go in series on a HomePower 3000?

No. One panel reads 41.6 V at 14°F against the 60 V limit, and one is the most that fits in series.

Does the EcoFlow 400W Rigid fit an Anker SOLIX C300X?

It would need an MC4 to XT60 cable, and the station's 28 V limit is well below 41.6 V at 14°F. That pairing is outside the voltage limits.
