I see the term "grid inverter" used in the diagrams
Just wanted to be clear, this is an inverter which takes DC from solar PV panel and converts to AC, i.e. a "string inverter", but it cannot charge a battery?
thanks for taking a look
I believe that it refers to any inverter that can inject energy into an AC grid.
You are correct for simplicity. It directly inject DC from solar to AC (loads/appliances) directly. The term usually refers to PV inverters that don't power up unless Grid (230v or 120v) voltage is present even if there is solar.
(It's a clear as mud these days, since some grid tied inverters can have a battery added to them and some have a feature where they can run small non surge loads during a blackout)
Because Victrons are bi directional they can charge the battery bank through the Victron with excess solar.
Thanks Alex,
Just checking, by AC grid you're referring to electricity company supply to house ?
Sorry maybe I wasn't clear... Language barrier... :-))
In my mind, grid = multiple lines.
Thus, there is electricity company AC grid and there is house AC grid.
I was referring to any AC line. In other words, grid inverter = AC coupled inverter.
