Solar power supply system is made up of solar panels. Solar controller. Batteries. If the output is AC 220V or 110V, it need inverter.
The action of each part is:
1. Solar panel: It is the hard core of solar power supply system. Its action is changing radiating power into electric energy or keeping in battery, or driving loads.
2. Solar controller: The action of controller is controling running order of whole system. It can also avoid battery overcharging or over discharging. In some district, it has the action of temperature correction. Some other additive function such as light control switch. Time control switch is selectable.
3. Battery: Commonly we use lesd-acid battery. In microsystem we can also use nickel-hydrogen battery. Nickel-cadmium battery or lithium battery. Its action is storing electric energy and releasing when need.
4. Inverter: The output is 12VDC. 24VDC. 48VDC commonly in solar power supply system. In order to supply electric energy to electric equipment of 220VAC, it has to change DC current into AC current. So it needs DC-AC inverter.
Beijing feiqiao International Science & technology Co, Ltd is built in 2004. It is a professional corporation in design, research and development, manufacture and vendition of solar PV system and all kinds of inverting electrical source.
Our company has a high-tech troop. The proportion of them is about 20% of our stuff. All of our sales personel have correlative knowledge of electrical, machine and sales.
Since our company built, the 20w-200kw solar and wind energy systems we design, integrate and install are widely used in the fields of police, national defence, communication, traffic, industry control and so on.
At the same time, we supply large PV stations and small housing systems to village schools, hospitals, rural areas, and frontier defence sentry. In the filed of renewable energy, we depend upon speciality, perfect technology and fine after-sale service won a high prestige.
