Based on solar panels, solar power generation systems can be formed, which can be divided into two major types of systems, namely off-grid systems and grid-connected systems. The network here refers to the national grid. Let's talk about them one by one:
① Off-grid definition: refers to the use away from the national grid power supply. The off-grid power generation system is mainly composed of solar panels, controllers, batteries, and wires. If the output power is 220V or 110V, an inverter is also required.
Off-grid system accessories list and functions
① The role of solar panels: convert sunlight energy into electrical energy
②The function of wire and crocodile clip: connect board and board, board and battery and other parts
③ The role of the solar controller: protect the battery from overcharge and over discharge, discharge time control, and prevent night charge
④ The role of off-grid inverter: convert the DC power from the solar panel into household AC power for the load
⑤ The function of the battery: store the electricity generated by solar energy during the day and use it at night
⑥ Load: household load such as TV FAN, microwave, printer etc
⑦ The role of the fuse: It is used to ensure safety, usually the use of these accessories should consult the local power engineer
②Grid-connected definition: It is used after being integrated (connected to the national grid). The grid-connected power generation system is that the direct current generated by the solar panel is converted into alternating current that meets the requirements of the commercial power grid through the grid-connected inverter, and then directly connected to the public grid.
