My Bluetti EP500Pro is integrate into my main house circuit as Backup Powersystem and beside this i have a offgrid system with 48V Batterys. Connectet to this offgrid System are two 400W Panels.
To charge my Bluetti with Solar too, i want a switch where i can switch between charging of my offgrid system and my bluetti EP500 Pro.
I found this thing on Amazon:
It has three positions (neutral, system 1, system 2)
Is it possible to do such a thing with this kind of switch?
