Solar inverters have one core function to convert DC from the solar panel into AC, which can power household appliances or be sent into the grid for energy credits.
There are two main types of home solar inverters:micro inverter and string inverter. Microinverters have become the most popular option because they don’t require additional equipment to meet electrical code requirements, can be used for intricate system designs, and don’t have the same shading issues as string inverters. String inverters are designed to manage groups( or series strings) of panels plugged into an input on the inverter, while micro-inverters independently monitor and control each module via MPPTs which minimizing efficiency losses due to shading, weather, any module failure and other factors.
Micro-inverters are installed underneath each solar panel on your roof or balcony or garden varying flexibly according to your scenario. Some micro-inverters allow you to attach two or four panels to each unit.
Here is a simple summary of the pros and cons of string inverters and micro inverters to help you decide whether you should consider them for your solar house.
