    Rich Solar replied. Bad fuse all they said.

    no power from panels?

    I think this may have been the problem. I checked closer with the fuse and saw that it had arcing marks all around it. The fuse holder had corresponding marks on the the locking tabs that hold the fuse in place. No other marks on the ends of the fuses or elsewhere were noticable. I think the...

    no power from panels?

    How could there be a current going through the in-line fuse from the solar panel get to be more than 30 amps and blow that fuse? I am a novice at this and is a bit puzzling. Don't understand what the function of that fuse would be if the panels could never exceed 20.4 amps with 10 gauge wire...

    no power from panels?

    If my batteries have reached 100% full during the day and I put a load on the system does the controller now only send power straight to the inverter and bypass the batteries? If so, is it possible that the load if it were say 30 amps or so would that cause the 30A inline fuse on my panel array...

    no power from panels?

    Thank you, so my 30A fuse is appropriate. Can't figure why the fuse blew.

    no power from panels?

    Discovered that I had a 30A inline fuse that blew. lt was connected inline on the postive wire from panels on roof to controller. I thought it was a 15A but not. Put in new fuse and everything seems to be working okay as it was previously. I bought the 1600 watt 24volt solar kit from Rich...

    no power from panels?

    What scenario would cause my in-line 15 amp fuse to blow that is on the positive line on my roof from my panels to my controller inside the house?

    no power from panels?

    My system has been up and running for a few months with no problems. Noticed this morning that the controller does not show any input from the panels on the roof. From the on/off switch I took the two -/+ leads coming down from the roof from the panels and tested and only showed 2.3v. Should...

    300A fuse caught fire?

    My 2/0 cable is rated from -50C to +105C. The manufacturer of my 2/0 cable, Windy Nation, states it is rated for 325 amps and temp rated from -50C to +105C. My total draw on my batteries through my 24 volt 3000w inverter is about 2800 watts if everything is turned on all together. Was...

    300A fuse caught fire?

    Wasn't sure about the 300A fuse all along. I am now trying to decide on going with 175A or 200A. I am fortunate to have been able to shut down the system in time. From the posts above am convinced that the way I had the stack with the nut in between the two lugs was the problem. Shudda known...

    Fused Confused

    Am a novice. Read lots lof stuff trying to figure the correct fuse (battery bank to inverter) for my system and still not sure. Sorry. I have a solar back up system for my house. 1600 watts solar panels on the roof, (3) LiTime 24v 200W batteries in parallel. 24V Giandel 3000W inverter with...

    300A fuse caught fire?

    okay thanks. Will get the blue Sea T class fuse holder. Want to make sure I get the right T class fuse. What would be best slow blow or fast blow? My system consists of (3) LiTime 24v 200ah batteries in parallel. 3000W 24v Giandel inverter. On the inverter it says 24V 150A input and 3000W...

    300A fuse caught fire?

    My system has been up and running perfect for 2 months, no problems. This morning when throwing a switch on the transfer box that had my under the sink hot water heater in line the 300A slow acting fuse melted and caught the 2/0 wire insulation and the fuse holder on fire. I heard the inverter...

    volts time amps equal watts dudden it?

    Thank you. My system is mostly a backup system for my house in case the grid goes down. I am using it a little on sunny days to run a couple freezers and refrigerator through my transfer switch and some nights which only takes them down to 80-85%. Most likely willl never fully discharge the...
