Am considering adding Tigo solar optimizers to 12 year old solar arrays. Anyone have any experience with them? Are they quiet? Noisy? Also, anyone know of RFI forums where I might post a question like this?
Paul,W1VLF, of the ARRL gave me some good advice about these but since he didn't have direct knowledge, suggested I poke around on Internet, so here I am poking around.
This house has two old-school arrays, no per-panel electronics, about 400V DC comes down to two SMA string inverters. These built-like-a-battleship inverters seem to be RFI quiet. But there are shading issues so I'm hoping to squeeze a little more juice out of the 40 panels up there with these things which seem to be made just for my situation:
