Hello.
*I have sets of solars.
*And grid inverters to go with them as well!
I also have all the micro inverters that comes with each solar.
They all produce strong power!
They all work like a champ!
Never had a issue with them at all!
Grid inverter does work also.
It's used to hookup from a power pole into your house shop garage. Etc!
It's made to save not only on your power but also have so much of a percentage of power plus money per year!!
By using grid/power inverter.
