“Yup. Modern inverters are smart ...”
SMA Sunny Boy has that feature. Will run off grid when the suns out of course.
If you have solar ? save my freeper mail, i’d be glad to share my over 50kw of operation at homes in Florida. Even got solar to supplement a diesel generator output that you will be told, no way.
Excellent! When I was in the market, the solution wouldn’t run without the grid. Good for saving money but definitely not a back up if the power grid goes down.
A stand alone design has to be provide a decent level of power. Or you have to be smart and unplug everything in your home except the few items that you want to charge or to run during a power outage. Or maybe a second power distribution system — main AC and then AC backup. Hey, why not DC in the house? A converter from solar panel DC to low/safety DC would be simpler versus an inverter that takes panel DC converts it to AC and then the AC is converted back to DC (usually at the load and in the device that you are powering). You might even be able to run some AC loads off of the DC power or have some kind of OR configuration. Straight AC motors can’t run off of DC but your average personal computer and other like devices can probably run directly off of DC by plugging the AC cord into your “DC bus.”
I don’t have solar but am interested. Thanks!
Anyway, if they do have a DC type motor, then they might be able to run off DC, too.
