Solar power system composed of solar cells, solar controller, battery.If output is AC 220V or 110V,also need power inverter.The function of each part as follows:
1.solar cells: solar panel is the core part of solar power system,it also most valuable part of the solar system.Its function is transfer the solar radiation to electrical energy,or send power store in batteries, or loading device
2.solar controller: solar controller is used to control the working state of the whole system,and provide over charging protection,over discharge protection for battery.where place in a larger temperature difference,some qualified
controller should also have the protect function of temperature compensation.Other additional functions such as light control switch,timely switch should be optional.some brand such as “Hanfong
” “Winiversal” ”Gamatong” is good and stable quality.
3.Battery: lead-acid battery in general,small micro-system,can also be used nickel-hydrogen battery,nickel cadmium battery or lithium battery.Its role is store energy produced by solar panel.
4.inverter: in general, solar panel output is 12VDC,24VDC,48VDC.For It can use for device with 220VAC.Hence we need DC-AC power inverter transfer DC power produced by solar panel to AC power.
Hanfonf is manufacturer profession in power inverter and solar controller and battery for more than 20 years,the quality is always good and stable.
