EcoFlow RIVER 600 Series User Manual page 9

The front side of the Bifacial Solar Panel has a junction box. This side of the panel generates power by being positioned
perpendicular to the sun's rays. Since the rear side of the panel faces away from the sun, it does not generate electricity
in the usual way. Generally speaking, the rear of the panel uses ambient light to increase the overall performance of the
product by up to 5%-25%. This figure is higher if mirrors are used, or when ambient light levels are high. Using the
product with the rear side of the panel facing the sun generates 80% of the power when compared to using the front
side. Using the panel in this way does not have a negative effect on the product.
Can I use non-EcoFlow branded power stations with the 220W Bifacial Solar Panel?
Yes, but only certain types. The power station used must be compatible with MC4 standards in order to work properly. In
addition, other brands of power station may not offer the same levels of compatibility as EcoFlow-branded power
stations, may have lower nominal power ratings, and may not offer the same levels of performance.
Can I connect both 110W and 220W Bifacial Solar Panels together in series?
Yes, but this is not recommended. While the voltages of the two panels are identical, the current ratings are not. This
means that when the panels are connected in series, the current will be limited to that of the 110W panel and the full
performance potential of the 220W panel cannot be released, resulting in a 1+2<3 scenario. Please purchase panels of
the same size if you intend to connect multiple panels in series.
Can I connect 220W Bifacial Solar Panel in parallel?
Yes, but this is not recommended. 220W solar panel have a maximum current rating of 12A. Though these panels
can be connected in parallel, DELTA and RIVER series power stations only support a maximum current of 12A. Parallel
connections increase power output by doubling the current, but connecting the panels in this way would result in a
1+1=1 scenario whereby the current is limited to 12A by the connected devices. We do not recommend connecting the
panels in parallel, unless you use a different brand of power station with an input current of 20A or above.
