Hello Everyone,
I am planning to build a modular solar power system for my future house,
What I would like to do is to have a system that:
-Is modular (I'd like to start with just a few panels first, just enough to meet the minimum voltage of the inverter, then add panels progressively)
-can work off grid, with a battery backup (I can build the batteries myself, slowly adding capacity over the years)
-can also work grid tied, because obviously at the beginning I won't have enough power for the whole house
I'd like the system to work as follow:
-whenever there is sunlight, first charge the battery to 100% SOC then selling whatever is left to the grid.
-Once the battery is charged and there is no sun anymore, use the power from the battery until it is discharged, then go back using the grid.
I've seen a lot of people praising the Growatt inverters, especially the 5000ES ones. They seem to be quite modular, powerful enough and from what I've red so far people seem relatively happy with these. What I like about them is that they feature everything in a single unit (charge controller, inverter, etc.).
They seem pretty good to me, but I can't really find a clear answer as to how they work once grid tied. They have an input for the grid connection so I suppose they can work grid tied, but they are marketed as off grid, which I find a bit confusing.
Do you think it is possible to reach all these goals with a growatt 5000ES unit? How does it normally work once the grid is plugged on it?
Thanks a lot in advance for your answers!
