     EcoFlow 400W Rigid Solar Panel FAQ


    A: On a sunny day without clouds and direct sunlight, the power range of a 400W solar panel is between 320–350W (this data is obtained under the conditions of irradiance of 800–900W/m2 and the panel surface at 50°C (122°F)). The nominal data of the solar panel is obtained by testing under the conditions of AM1.5, meteorological conditions of 1000W/m2, and panel surface temperature of 25°C (77°F). A power close to the nominal value can usually be reached at midday on a sunny day in winter.


    A: 1. The standard 400W solar panel supports up to 2 in series. 2. For non-standard solar panels with a wattage lower than 400W, the voltage and current can be used in series at 11-100V DC 10A. They can be connected in parallel or in series, but using solar panels with different wattages is not recommended.


    A: DELTA can be charged using any solar panels with the same solar connectors and within an input range of 400W 10-65V DC 10A.
