The main answers before you connect.
Does the EcoFlow 400W Portable fit every power station?
No. Beyond 400W, the working voltage, the highest voltage in the cold, the current, the connector and the polarity all have to stay inside the station limits.
What is the difference between working voltage and open-circuit voltage?
Under load the working voltage is 41V. With no load connected the panel can reach 48V, and in cold weather that can rise further.
Can I connect several of these panels?
That depends on the wiring. In series the voltage adds up; in parallel the current adds up. Test the complete array in the Solar Lab.
