The Component Part And Function of Off-grid Solar Power System

Off-grid solar power system is a completely independent of the existing power grid, it can also be used in remote areas. Whether stationary or mobile home solar power system equipment, its components are substantially the same, including solar panels, batteries, solar charge controllers and solar inverters. According to the requirements of size and function of the required system components are also different.

One: Solar panel
The function of the solar panel is to convert light energy into electrical energy, which can absorb light and directly generate direct current. After connecting the power supply line, the DC power can be stored in the storage battery in the way of chemical energy.

Two: Storage battery

Battery is the electric energy storage device, through the way of electric energy into chemical energy to storage the electricity generated by solar panels. In the needed of using electricity, can be released from converting the chemical energy into electricity.

Three: Solar charge controller

Solar charging and discharging controller act as a central hub, control and regulate the working state of the solar power system, and played a protection function role of the battery overcharge ,over discharge. Place in a big temperature difference, the qualified controller should also have the function of temperature compensation. Other additional function such as optical switch, control switch should be controller’ optional.

Fourth: Solar inverter

Direct output voltage of solar power system in general are DC 12V , DC 24V, DC 48V. For AC 220V load appliances to provide electrical power, it need DC power which is generated from the solar power system to converted into AC 220V or AC 110V power. Therefore, it must use the DC-AC solar inverter. which function is to increase voltage, and the device that converts alternating current to direct current.

In the actual process of the specific installation of solar power system, according to the size of the power system can also need to configure additional components such as junction box. And in order to ease of use, all-in-one solar power generation equipment is a good choice, for how to choose a suitable mobile home solar power equipment--- portable solar generator, all above parts are very important reference factors.
