Mastervolt Soladin 600 had not been in use for quite a long time. I connected it up to three panels (135VOC) facing the early morning sun just to use some earlier insolation. It worked initially, but then it appears to have failed on the DC side (no indication of panels providing any volts). Mains is OK to the board and there is 100V, or so, on the DC inputs but no illumination whatsoever.
No rush, as I have connected the Steca and the early sunshine is now reducing the leccy take, but I would like it working again if possible.
