Microinverters harvest more power from solar panels and are easier to install, monitor and maintain. Another big advantage with Enphase microinverters: they combine ultra-reliable components with a distributed architecture that makes for a more resilient system. That’s something string inverters can’t do.
Based on our analysis and experience, I am convinced that the Enphase value proposition is better than the DC optimizers on the market today. Enphase is much simpler and easier, with lower cost for engineering and field labor; whether comparing it to central inverters, DC optimizers, or other inverter architecture schemes. Energy production data support the Enphase selection, and I believe Enphase is more reliable based on installing several hundred Enphase systems and several DC Optimizer systems over the last 5 years.
I feel that customers are catching on to the misconception that you can just buy SolarEdge optimizers and you're getting all the benefits of a microinverter system. You have a lot more points of liability. The warranty is half as long. Why try to make a string system like a microinverter system? Why not just use microinverters?
