Grid-Tied Inverters
The grid tie solar inverter’s working principle is just like a conventional solar inverter but with a significant difference: a grid tie inverter converts the DC output of your solar panels directly into AC. Then it synchronizes this AC with the utility grid frequency.
- During peak sunlight hours, the electricity produced by your solar panels may exceed household demand. In this case, the extra power will go to the grid, and you’ll receive a credit from your utility company.
- At night or during cloudy weather, when your solar panels are not producing enough power to meet your household demand, you’ll pull electricity from the grid as you normally would.
- An on-grid solar inverter must be able to shut down automatically when the utility grid goes down, as feeding electricity into a downed grid can be dangerous.
All solar inverters eventually reach the end of their useful life, but understanding why and how they go bad is key to making sure that you get the most out of your investment.
