Has anyone connected the AC output of the Growatt SPF 3000TL LVM-ES directly to a home's circuit breaker panel? Under features the manual states that "solar and utility grid can power loads at the same time". Also there is a schematic showing the proper way to hook the SPF 3000TL LVM-ES to a home's load. However my contact a Signature Solar says the SPF 3000TL LVM-ES can not be connected directly to a home's CB panel. I emailed Watts247 but have not heard back from them. I have seen several videos' of this unit used off grid but none with it connected to the grid. Any experience using this unit grid tied? I am limited to 12 solar panels so I am unable to create enough power to go off grid.
