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.

battery for storage, or to drive the load.
(2) Photovoltaic combiner box:
The photovoltaic combiner box is used to reduce the connection between the PV module and theinverter/controller and is convenient for maintenance. It has perfect functions such as anti-counter-attack, over-current protection and lightning protection to improve the product. Safety and reliability.
(3) Solar controller:
(3) Solar controller:
The solar controller provides the functions of the photovoltaic module to charge and discharge the battery,such as overcharge, overdischarge protection, temperature compensation, etc. Other additional functions such as light control
switches and time control switches should be optional for the controller.
(4) Pure Sine Wave Inverter:
switches and time control switches should be optional for the controller.
(4) Pure Sine Wave Inverter:
The electricity generated by the PV module is DC, and it cannot supply power to the AC load. The inverter needs to convert DC power into AC power and provide it to the load.
(5) Battery:
(5) Battery:
Generally, lead-acid batteries and colloidal batteries are used. In small and micro systems, nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the energy generated by the solar panel when there is light, and then release it when needed.

Comfortable and Slick
Color: Grey, Size: X-Large
The track suit has been my tai chi workout go to. The fabric is light and non constrictive so I can move effortlessly. The material is soft and feels nice. Does not get too wrinkly when folded. The color is nice.
Top fits nicely, true to size (6’ and 190 lbs). The bottoms are a bit baggy though but my bum is flat, so can complain. I think next time I would purchase separate pieces and go with XL top and L bottom. Perhaps mix the colors too so I don’t look like an orderly on break!
I will caution on wearing this type of material over spandex or slippery underwear. I was walking my three large dogs and they got tangled and the leash snagged and pulled down my pants exposing my underwear to the world. Luckily, I had clean undies with no rips, although no one was around the trail we were on!
This is my first Coofandy purchase and I would definitely purchase again.
