Solar PV Inverters
How Do Inverters work?
Inverters take the DC power from the solar panels and convert it to AC Power which is sent back to the grid and/or through the building. You use the power that you generate and the excess energy goes back to the grid and your neighbors are using the power and you get credit for it.

Central Inverters: All the panels are wired in series/parallel strings back to the inverter. They are generally the least expensive inverter however, not the most efficient and shading on one string effects the other string.
Micro Inverters: Each panel has its own Micro Inverter attached to it making each panel work independent of another. Shading of one panel has no effect on the other panels. Each panel is monitored online so you can see the production or any problems. Micro Inverters are the most expensive inverters however they are more efficient than Central Inverters.
Central Inverters with Optimizers: They arewired like a string inverter but the optimizers are mounted below each panel like Micro Inverters. In my opinion, this is the better way to go. The optimzers allow each panel to work independently, therefore, it works very similar to Micro Inverters. However, they cost less and they have about 1/3 of the components as the Micro Inverters up on the roof so the chance of failure is less. Central Inverters with Optimzers are monitored online as well.
