Comparison of grid-connected, off-grid and hybrid systems

Jan , 06 2024

There are three types of solar panel systems: grid-tied (on-grid), off-grid, and hybrid solar systems. Each type of system has a unique setup that affects what equipment is used, the complexity of installation, and, most crucially, your potential costs and savings. What would be the best in your situation? Let’s take a closer look at the benefits and downsides of grid-tied, off-grid and hybrid sol...

Zero line electrification poses the following hazards

Feb , 03 2024

(1) When the zero line is disconnected, due to load asymmetry, the neutral point drift is caused, and the voltage of one phase of the light load will increase. When it exceeds the rated voltage of the electrical equipment, it will shorten the service life of the equipment. If it exceeds the rated voltage too much, it may even damage the equipment and cause a "group explosion" of household applianc...
