Solar energy is no stranger to us. Now we continue to develop solar energy and make permanent use of sustainable energy. We can't stop using energy in specific places like home or factory, which led to the invention of portable solar power generator. What is a portable solar power generator? What is the key part of it? Let's explore together.
The portable solar power generator is an independent photovoltaic power generation system that integrates charge and discharge control, inverter and energy storage, and converts solar energy into electrical energy. It is a small photovoltaic power generation system with high integration. The system can provide clean and free energy for electric lights, televisions, computers, fans, electric hand drills and other commonly used appliances, and is particularly suitable for use in areas and places without electricity such as marginal mountains, islands, border posts, outdoors, disaster relief, and various fishing boats.
Solar panel: The solar panel is the core part of the solar power generation system and also the most valuable part of the solar power generation system. Its function is to convert the solar radiation capacity into electric energy, or send it to the storage battery for storage, or promote the load work.
Solar controller: the function of the solar controller is to control the working state of the whole system, and to protect the battery from overcharge and over discharge. In places with large temperature difference, the qualified controller shall also have the function of temperature compensation. Other accessory functions such as light control switch and time control switch are optional for the controller.
Battery: for portability, the system uses lithium battery, which has high storage energy density, 6-7 times that of lead-acid battery; Long service life; Low self discharge rate, less than 1% per month; Light weight, about 1/5-1/6 of lead-acid battery in the same volume; High and low temperature adaptability, can be used in - 20 ℃ - 60 ℃ environment. The battery is green and environment-friendly, and does not contain any harmful heavy metal elements and substances such as lead, mercury and cadmium, no matter in production, use or scrap. The function of the battery is to store the electric energy generated by the solar cell under the illumination and supply power to the load at any time.
Inverter: In many cases, we use 220VAC, 110VAC AC power supply. Since the direct output of solar energy is generally 12VDC, 24VDC, 48VDC, in order to provide power to 220VAC electrical appliances, it is necessary to convert the DC power generated by the solar power generation system into AC power, so DC-AC inverter is required.
