Technical FAQs 4

How does a grid-tie inverter work?

A grid-tie inverter connects your solar system to the electricity grid, allowing you to use solar power while sending excess energy back to the grid, often earning credits or money. A grid-tie inverter converts direct current (DC) power from solar panels into alternating current (AC) power that can be used in your home or fed into the grid.

Do grid-tie inverters require batteries?

No, grid-tie inverters do not require batteries. Excess energy is sent to the grid, and you can draw from the grid when your solar system isn’t generating enough power. 3. Can I use a grid-tie inverter for an off-grid system? No, grid-tie inverters are designed to work with the electrical grid.

Does a grid-tie inverter work with an off-grid system?

No, grid-tie inverters are designed to work with the electrical grid. For an off-grid system, you would need an off-grid inverter that can store energy in batteries. A grid-tie inverter is an essential component of a solar power system that helps convert DC power from your solar panels into usable AC power.

How do inverters provide grid services?

In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
