Can you install any inverter when you decide on solar? The answer is simply NO.
The role of the inverter is to convert the Dual Current “DC” electricity which is produced by the solar system into Alternating Current “AC” electricity so that your home can safely use the solar power electricity. Therefore, the solar energy is channeled into your inverter.
There are three types of inverters (there is a raft of great technical material in the market if you’re so inclined). These are as follows:
- A single string inverter;
- Micro inverter; and
- Hybrid inverter.
These are designed for Single Phase, Dual Phase and Three Phase power, and you can use multiple inverters depending on your system size and power needs.
If you are considering with some level of certainty that you will invest in battery storage, say in the next two years or so, then a Hybrid is the way to go, albeit more costly. We will write a separate blog relating to Hybrid and batteries soon.
Inverters directly affect how much energy you will reap from your solar panels, so YES, it is important to select a quality inverter.
Note: All reliable installers and sales companies will recommend inverters on this list. Be very wary of going cheap and warranties of 2 to 5 years should be avoided. Select a warranty upgrade, because if anything is to fail in the first 10 years, it is likely to be the inverter. For a few extra dollars, quality matters. However, having made this statement, even the quality end of the market can fail. Be sure and go for 10-year warranties! And check the sales documentation!
All inverters work hard, so talk with your consultant about reliability, warranties, new for old, repairs and the like. Asking these questions and understanding the role of the inverter will give you confidence in your solar choice.
Finally, reliable installers will install the inverter in a shaded area or put a sun cover to create shade.
