Introduction to solar power generation system
1. Our company's off-grid solar power generation system is a solar green power supply system designed specifically for commercial users, residential users, enterprises and institutions. The power covers 300W_50KW. Solar energy can be used as the main power supply, and the mains and solar power supply can be automatically switched.
2. The off-grid power generation system is an independent solution, so it can be installed in most places and is easy to maintain locally. They are reliable, clean and safe new energy sources that can replace diesel generators, and their application prospects are very broad.
3. Working principle of solar energy: The photovoltaic array converts solar energy into electrical energy under the condition of sunlight, and supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; when there is no sunlight, the battery pack supplies power to the DC load through the solar charge and discharge controller, and the battery also directly supplies power to the independent inverter, and is converted into AC power through the independent inverter to supply power to the AC load; The solar power generation system is generally composed of a photovoltaic array composed of solar cell components, a solar charge and discharge controller, an off-grid inverter, a battery pack, a solar mounting bracket, a DC load and an AC load, etc.
1. Solar panel: 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 sun's radiation capacity into electrical energy, or send it to the battery for storage, or drive the load to work;
2. Solar charge and discharge controller: It mainly controls the working state of the entire system, and protects the battery from overcharge and over-discharge. In places with large temperature differences, qualified controllers should have temperature supplement functions, and other additional functions such as light-controlled switches and time-controlled switches.
3. Off-grid inverter: The direct output of solar energy is direct current. In order to power 220V AC appliances, the direct current generated by the solar power generation system needs to be converted into alternating current. At this time, the off-grid inverter plays a key role;
4. Battery pack: Store the power generated by the solar panel when there is light, and release it when needed;
5. Lightning protector: Disconnect and protect electrical facilities such as charge and discharge controllers when lightning strikes;
6. Solar mounting bracket: Fix the solar panel. Due to different installation methods and different bracket designs, customers need to confirm in advance when purchasing.
