The solar power system consists of photovoltaic modules (including brackets), photovoltaic combiners, solar controllers, and batteries (including battery cabinets). If the load is AC equipment (220V or 110V), you need to configure the inverter. The functions of each part are as follows:
(1) Photovoltaic modules:
(2) Photovoltaic combiner box:
(1) Photovoltaic modules:
Photovoltaic modules are an important part of solar power generation systems and a high value part of
solar power generation systems. Its role is to convert the radiant energy of the sun into electrical energy, or send it to a
battery for storage, or to drive the load.

Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.
