Inverters take the direct current (DC) captured from the sun and invert that to alternating current (AC) that can be used for all purposes and exported safely to the electric grid. There are two types of inverters:


This inverter technology has progressed for over 60 years and is used exclusively in commercial application as well as residential. The efficiency of inverting DC to AC is approximately 95% of the captured electricity.

This type of inverter harvests more solar energy than any other. They are proven and reliable. A typical central inverter could last 15 to 20 years and be replaced at an affordable cost. Unlike micro inverters, the system array or panels do not need to be disassembled to repair or replace the inverter.


A micro inverter is very small and each panel has one. The sales pitch is that if one fails, “the rest will still work.” From vast experience, we can tell you that you will spend the rest of your life replacing them one after the other. Replacing a defective micro inverter (basically a toy) is very time consuming and expensive. Yes, they may offer a “great” warranty, but taking apart the system to reach the “broken” inverter is a labor nightmare. Micro inverters have a much lower rate of inverting DC to AC, approximately 86 to 88% inversion as compared to the 95% of central inverters.

Electronics do not like heat. Central inverters often have built-in fans to keep them cool. Micro inventers use no fans. They also suffer from the heat on the roof where they are installed. Micro inverters and the Philippines are a bad combination.

From our experience, micro inverters are a cheap way to install. The installer saves money while having a great sales pitch. “Every panel has one.” And every one will fail in due time. Good luck on getting your installer to continue to replace them month after month.
