I am watching a video of a guy with a 13kw solar panel array on his house. Only problem is his inverter is only 6kw. That sounds incredibly dangerous to me. He says he was told it was not dangerous because the extra power generated will go straight into the batteries via the MPPT controller and will not overload the inverter. Can someone confirm or deny this is the case?
I know a 6kw inverter can convert a max of 6kw dc power from the batteries to ac power for use with no grid and no generator. My question is what if for instance 10kw of solar comes in one day. Will all that extra power just go into the batteries via the MPPT controller, or will it overload the inverter and possibly cause shutdowns or even explosions? Thanks for the help. Here is the video

Of course I would only have ~1kw of solar on my boat with a maybe 10kw quattro inverter, so this situation would not apply to any boat setups. There just isnt enough room for that much solar on a boat. But it sparked my curiosity. I just always assumed never have less inverter wattage than solar wattage. But maybe this can be offset by the MPPT controllers going straight to the battery bank? Not really sure. Of course the MPPT controllers would have to be rated to handle 13kw which is a hell of a lot.
