Hi!
I have a Sunny Boy 3.0 + 3kW PV installed. I also have contract with local distributor for selling extra energy to the grid. Now i purchased Sunny Island 8.0H-13 and I'm trying to find out the proper way of connecting it to the grid.
My main goal is to have battery backup with AGM batteries rather than reducing energy costs. Some day maybe i will use it for cut energy costs as well
While looking at the documentation , forums, web i noticed that there are two ways of connecting SI to the grid:
1) parallel to the grid (like SB): in this case i would need to have Home Manager for regulating energy flow to the grid(if i want to limit it), disconnector from the grid (in the case grid goes down) + i can connect generator to AC1 as extra source if necessary
2) grid is connected to AC1: loads and SB are connected to AC2 in separate local grid + i can add generator to AC1 (trough transfer switch because grid is also connected to the AC1).
I guess in the 2) case i don't need to have extra disconnector from the grid because it is allready implemented inside SI?
Also, i guess in 2) case SI would use more energy even if in backup mode because energy flows trough it all the time?
Does anyone have suggestions about this dilema, or there is no dilema at all and there is only one right way to do this?
Thank you all in advance.
