The main difference between a micro inverter vs string inverter is the performance. The central inverters link all the solar panels in a chain that attaches to a single inverter, while the micro inverters link to one panel at a time.Micro inverters have the advantage of allowing every panel to work independently, facilitating close monitoring of how each performs. On the other hand, the string inverter lets all the panels work as a team, and any hiccup affects the entire system.However, its advantage over micro inverters is that it is cheaper and easier to install and maintain.

Inverter plays an important conversion role in the solar system, it needs to convert the DC generated by the solar system to AC used by home. Generally speaking, string inverter can connect PV panels in series and parallel to form a PV array, then convert DC into AC and connected to the grid.Micro inverter also convert DC to AC, but the difference is that a micro inverter is installed after each PV module, and the module level conversion efficiency is much higher than that of conventional inverters.

Solar micro inverter is an inverter designed to connect with a single PV module. It is a device that directly converts the DC generated by each module into AC and then connects to the grid. The main advantage of micro-inverter is that each module can be independently controlled by MPPT function(Maximum Power Point Tracking), which will greatly improve the overall production efficiency.
