We have also asked a group of solar experts about the best 10kW inverters for them
For the sake of information gathering, we have made a poll in one of the most active Facebook Group for solar experts called Quality Solar. They were asked with the question: “What are your top 10 string inverters for 10kWac installation?”.
A big thanks to all the people in this community who voted and shared their thoughts, so here is the result of the poll as seen below.
Top 10 string inverters with 10kW capacity according to Quality Solar
Fronius SYMO 10.0-3-M
To be considered one of the top tier string inverters, Fronius has packed its inverter model SYMO 10.0-3-M with unique and helpful features. This inverter is produced by an Austria-based company.
It boasts with its easy-to-install process, which they call SnapINverter technology. It is the design for the inverter backplate, housing the AC and DC terminals, which will be fixed to a wall or a rigid structure. After fixing it, the main body of the inverter will easily slide and snap into the backplate while connecting both AC and DC connections into their proper terminals inside the device.
