WHAT IS AN INVERTER?
Simply put, this component transforms DC (Direct Current) power into AC power (Alternating Current). DC has only one direction of movement, which is suitable for Solar Panels because they only need to absorb sunlight and drive it through the system in one direction. This might be an oversimplified explanation but for now, that’s all you need to know for the purpose of this article.
AC flows in both directions , all of your appliances are powered in this way.
Now we have that out the way let’s move on to the next part.
How do they work?
You get three main types of Inverters you can use, each one functions a bit differently to the other:
GRID-TIED, OFF-GRID & HYBRID TYPES
The Panels are connected directly into the inverter which then, in turn, plugs into your building electrical box (DB Board).
Hybrids are used for Grid-Tied / Off-Grid / Storage and generator inputs. All different Solar Power applications are possible with Hybrid variations, which is the most versatile option. Hybrid inverters accept DC and AC power .
- Synchronise to the grid
- Disconnect if the grid goes down
- Use an alternative power source (solar, battery or wind)
- Detect if any power sources are depleted and switch to another
- Monitor power usage
