Solar Power System With Micro-Grid Inverters

I will brief about Micro-Grid Tie inverters in this section.

Micro-Grid Tie inverter is just a grid tie inverter, except that attaches to every solar panel. Its working principle is same as Grid tie inverter. The advantage is with Micro-Grid Tie inverter, you can add more panels or remove more panels without affecting the remainder of the circuit. In addition, if any solar panel fails to produce power , it can be easily isolated and fixed.

The downside is every time you buy a solar panel you have to buy a Micro-Grid Tie inverter. It results in additional cost to you.

This is therefore useful for industries that expand and want to add more panels to meet the energy demands. That said ,  for house owners this does not provide additional merit because the power consumed can be calculated with ease and high efficiency is desired, but not critical.

If you like to explore further, then look at the circuit below,


If you want to be 100 % tied to the grid without any battery then it is basically the same circuit diagram without the battery and sine wave inverter.
