The solar power generation system consists of solar panels, solar controllers, and batteries. If the output power is AC 220V or 110V, an inverter is also required. Here's what each part does. The solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert the radiant energy of the sun into electrical energy, or send it to the battery for storage, or drive the load to work. The quality and cost of the solar panel will directly determine the quality and cost of the entire system.
In the photovoltaic system, the electric energy generated by the solar cell is first stored in the battery, and then converted into 220V or 380V alternating current through the inverter. However, the battery is affected by its own charge and discharge, and its output voltage varies widely. For example, for a nominal 12V battery, its voltage value can vary between 10.8 and 14.4V (exceeding this range may cause damage to the battery).
The grid tied inverter is generally used in the system of large-scale photovoltaic power stations. Many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter. Generally, 3 phase IGBT power modules with high power are used, and the power is relatively high. Small uses field effect transistors, while using a DSP conversion controller to improve the quality of the power produced, making it very close to a sine wave current.
Solar inverter is the core power conditioning device of photovoltaic system, which accounts for 10-15% of system cost, and has high technical content. Solar inverter converts the direct current generated by solar cells into alternating current energy that can be directly integrated into the grid and load through power electronic conversion technology. However, what is the difference between a grid tied inverter and a micro inverter?
In the pursuit of a sustainable lifestyle, portable solar generators are increasingly becoming a household staple and a favorite in areas like outdoor adventures and emergency backup power. A common question is: Can a portable solar generator power a refrigerator? The answer is yes, but the key lies in properly matching the power output of the solar generator with the refrigerator's energy needs and using the refrigerator efficiently to reduce energy consumption.
Solar inverter is the brain of the photovoltaic power generation system. In the process of photovoltaic power generation, the power generated by the photovoltaic array is DC power, but many loads require AC power. The DC power supply system has great limitations— it is inconvenient to convert voltage, and the load application range is also limited. Except for special electricity loads, inverters are required to convert DC power into AC power. The solar inverter is the heart of the photovoltaic power generation system, which converts the direct current generated by the photovoltaic modules into alternating current, and transmits it to the local load or grid. It is a power electronic device with protection functions.
An inverter generator is a type of power generation equipment that converts raw power into a stable output, similar to the electricity transmitted to homes and businesses through power lines. The core principle of an inverter generator is to convert mechanical energy from fuels like gasoline or diesel into electrical energy and then use inverter technology to convert direct current (DC) into alternating current (AC). This inverter function is the opposite of a rectifier, which converts AC power into DC.
The solar pump inverter is the control part of the solar water pump. It plays the role of maximum power tracking and speed regulation in the system. The solar pump inverter converts the direct current generated by the photovoltaic array into alternating current, drives the water pump, and adjusts the output frequency according to the change of the sunlight intensity to realize the maximum power point tracking (MPPT).

Inverters are not only used during power outages and power outages, but can also be used outdoors. The inverter has power sockets through which you can connect electrical appliances. However, what you can connect depends on the rating and load capacity the inverter can handle. When the inverter is connected and turned on, it converts the DC current to the AC current that the appliances work on. It can also power sensitive equipment and make it work at its best.
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. Its basic components are a high-speed rotating impeller and a fixed snail-shaped pump casing. Usually centrifugal pumps have impellers with several backward curved blades fastened to the pump shaft and driven by the motor to rotate at high speed along with the pump shaft. There are two ports on the pump casing, the inlet leading to the center of the impeller is connected to the suction line. The tangential side of the pump casing is the outlet, which is connected to the discharge pipeline.
