I have used both Solis and Deye, and I would recommend Deye due to its huge range of features and configuration options. The only issue with Deye is the settings can be a little confusing. The Deye SUN-8K hybrid can run parallel strings (up to 200% oversizing) and has dual AC inputs so you can have both a grid and backup generator connection.
