FAQ
Central inverter and String inverter Comparison
In terms of money, string inverters will get more and more expensive vs central inverters as the field size increases. It's a heck of a lot of additional labor to hook up 100 string inverters of 10kW vs. 3 or 4 central inverters (which can also be bought in pre-configured 1MW units with some of the connections already done).
Personally, I would draw the line around 250 - 400 kW. Below that string inverters work out well. Above that central inverters have their place (and will save money). Can it be made to work either way, and work well? Sure!
