Description

A stretchable portable solar power unit

technical field

The utility model relates to a solar power supply device, in particular to an extendable portable solar power supply device.

Background technique

In response to the impact of global warming caused by the greenhouse effect, the public's awareness of environmental protection is gradually increasing, and countries are also starting to sign relevant environmental protection conventions to curb carbon dioxide emissions. Alternative energy has become a key topic of active research in various countries.

Since solar energy is an inexhaustible and non-polluting energy source, solar energy has both economical and environmental advantages. Therefore, governments of various countries have also begun to promote various applications based on solar power generation.

Generally, a solar generator device includes a solar panel, a battery, a solar controller, and an inverter. Among them, the solar panel is the core part of the solar power generation system, and its function is to convert solar energy into electrical energy, or send it to the storage battery for storage, or promote the load to work. The role of the solar controller is to control the working state of the entire system, and to protect the battery from overcharging and overdischarging. In places with large temperature differences, qualified controllers should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional options of the controller. The storage battery is generally a lead-acid battery, usually 12V. In a small and micro system, a nickel-metal hydride battery, a nickel-cadmium battery or a lithium battery can also be used. Its function is to store the electric energy from solar panels when there is light, and release it when needed. The inverter converts the DC power generated by the solar power generation system into AC power. In some occasions, when loads with multiple voltages are required, a DC-DC inverter is also used, such as converting 24VDC power into 5VDC of electric energy.

Currently commercially available solar power generators have the following drawbacks:

1) In order to effectively use solar panels to absorb solar energy, most solar panels are installed in open places that can be exposed to sunlight for a long time, and in order to improve the absorption efficiency of solar panels, most solar panels are large area design. However, such a design results in bulky solar panels that are not easy to store and transport. And when encountering bad weather, such as a typhoon, the large wind area of the solar panel makes the center of gravity of the solar panel unstable, and it is easy to dump and damage, resulting in shortening the use of the solar panel.

2) Since the entire product is bulky and heavy, it cannot be transported portablely, and usually needs to be carried by a forklift, which is very inconvenient. In addition, the solar panel, the storage battery and the solar controller are electrically connected by external wires. Since the structure cannot withstand the vibration during transportation, it is usually not allowed to move after the storage battery is installed, so as not to damage the electrical connection. Device does not work.

3) Most solar systems require a complicated wiring instruction, but it is too complicated and sometimes dangerous for people not familiar with electrical systems.
