The function of the solar controller is to control the working state of the whole system, and to protect the battery from overcharge and overdischarge. Where the temperature difference is large, the qualified controller should also have the function of temperature compensation. Other accessory functions, such as light-controlled switch and time-controlled switch, are optional for the controller.
For convenience of carrying, the system adopts lithium battery, which has high storage energy density, 6-7 times that of lead-acid battery; Long service life; Low self-discharge rate, which can reach below 1% per month; Light weight, about 1/5-1/6 of that of lead-acid battery in the same volume; High and low temperature adaptability, and can be used at -20℃-60℃. The battery is green and environment-friendly, and it does not contain any harmful heavy metal elements and substances such as lead, mercury, cadmium, etc. no matter whether it is produced, used or scrapped. The function of the storage battery is to store the electric energy emitted by the solar cell when it is illuminated, and it can supply power to the load at any time.
On many occasions, we use 220VAC and 110VAC AC power supply. As the direct output of solar energy is generally 12VDC, 24VDC and 48VDC, in order to provide electrical energy to 220VAC appliances, it is necessary to convert the direct current energy generated by solar power generation system into alternating current energy, so it is necessary to use DC-AC inverter.
Solar panels, batteries and inverters are indispensable components of portable solar power generation. Solar power generation can solve the problem of machines that usually use more electricity, especially those that need to store electricity, which can be said to be very convenient. But we need to remind everyone that when we use portable solar energy, we should also take good care of it.
