Hi @ZUMinUK I take it your in the uk im not familiar with the et solar so can’t really comment on them but I do have a couple of longi panels not connected to my ac300 at the moment but have them connected to a couple of ac180 really good panels if you are looking for panels the best place to get them in the uk is city plumbing at a good price.
Were your LONGI panels connected in series to a single DC input?
Those panels look great. However, I’m keen on bifacial, where I plan to mount them above a ridiculously reflective conservatory. The glare off this glass is BSC, almost making the room directly above the conservatory unusable in the height of summer.
