Enphase or SolarEdge: Battle of Microinverters vs Optimizers

Today, just about every residential and small commercial solar panel installation in Massachusetts uses either Enphase or  SolarEdge, which are microinverters or a system of DC optimizers paired with a single inverter.  Solar panels produce DC current when exposed to light, but the appliances in our homes run on AC.  In order to use the power coming off a solar roof (or to sell that power back to the electric utility), we need to convert the solar panels’ output to AC.  This is the job of an inverter (or inverters). The inverter is responsible for not only creating high-quality AC… read more →
