An on-grid inverter is a special device that help convert energy from solar panels into electricity we use in homes and businesses. When sunlight hits the solar panels, they makes direct current (DC) electricity. But most appliances need alternating current (AC) to work. Thats where the on-grid inverter come in. It changes DC to AC so we use it right away. If solar panels produce more than we need, extra power can goes back to the grid, like big power storage. This way we help provide energy to others and get credits for what we send.
Picking right on-grid inverter for your solar setup is important, because it make big differnce in energy you use and save. First, think about size of your panels. If you got lots of panels, you needs more powerful inverter. It should match total wattage of system. Another thing, look at effciency. Higher one means more energy from panels get used. Some have good effciency, others lower.
