You can charge DELTA and RIVER series portable power stations using the MC4-XT60 cable. You can connect solar panels together with a parallel cable, giving you enough power for your power plant thanks to the chaining function (4 x 110W parallel solar panels for DELTA, 2 x 110W parallel solar panels for RIVER series). Rain, wind or sun, your panel is protected with a cover. Also, using a flexible stand, you can adjust the angle of the panel from 0 to 180 degrees.
