Popped a 25 amp fuse with 260 watts of solar?
I'm set up in the lab (my patio) with my new 12 volt off grid system. I have a new Midnite 150 lite, 2 GC2's in series, 2 130 watt pannels in series. I had the same battery bank and series wired pannels on my sunsaver mppt with 15 amp fuses and never popped one. Now as before my pannels run through an inline 15 amp fuse and my loads run through another one. The battery bank is connected through a 25 amp inline fuse that popped yesterday on a cloudy day. The clouds never broke so direct sun never happend but they did lighten slightly and I saw 10 amps of charge current for an hour or so then pop. When I got home the clouds were thick again and I replaced the fuse with a 15 amp one just to be extra cautious and the system ran all night just fine. I've powered down this morning. Could it have been a sweep?
