Thanks so much! Very helpful.
How did you get in touch with imperial? My dealer has not put me in touch with them. Should I simply reach out thru their " info@imperial" email or you have a better suggestion?
I literally did as you noted, and with help of multimeter found a culprit short at the BAT+ connector inside the wirebox under the wardrobe. See picture below, There are two wires with 30A fuse that have not gone thru the fuse box. One goes to solar controller, which is fine. Second one goes into the bundle and get lost in the mix. As soon as I removed that fuse, short was removed and batteries are fine now. Curiously, everything seems to be functioning too! So I'm baffled what is the faulty wire for? Any idea? (Picture below. Two wires with fuse, I have removed the fuse of faulty one)
