It is odd when the class is silent. It usually means I said something stupid or stumps the class so I will ask a different question off topic. Is there any difference in performance between gold and nickel fuses?
2000k system only puts out 500 watt why?

You have serious problems with your system. If you want to solve your problems, get someone competent in to look at it. At this point I feel like I'm enabling someone with a poorly designed system to feel good about not fixing it, and instead make meaningless tweaks and twiddles.Comment

Answering your questions has become something of an exercise in futility. Answering your question about nickel vs gold fuses is like seeing a post "so my house is on fire and it's spreading fast. Should I invest in double pane windows or leave the original single pane windows in place? Cause it doesn't seem so cold right now."

... I am honestly doing what is in my budget I am mostly broke so funding is almost non existent. The fuse between the bank and inverter has got to be upgraded it got hot the other day and started to melt the fuse block and the wire jacket between the inverter.
OK. There are several potential reasons for the fuse block to melt:
1. Most likely the fuse holder is just not intended to be used with that high a current.
2. There may be a bad connection between the wires and the fuse holder. Make sure you are using the right size wires, with crimped connectors if necessary and with the screws properly tightened.
3. It is also possible that you have a poor connection between the fuse and the holder. This would also come under the heading of bad design, so see item 1.
It is almost NEVER the result of the fuse itself getting too hot, because at that temperature the fuse would be expected to blow very quickly.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

corrode faster, etc. Not the fuse, but the contact to the fuse holder. Bruce RoeComment

I am running off of a 250 Amp ANL fuse right now. I already ordered the 300 Amp replacement a few days ago it should already be here. I would like to move to a breaker like this
but am really unsure of it due to a review I seen and the guy said the connection lugs seem to be 1 or 2 mm too small for 24V system online distributors is like playing russian roulette you just don't know till you try when you really just don't know anything about the product.
I hate my inlaws sometimes 2 hours sleep in 72 hours makes me grumpy day and night have become one big blur. I am sorry if I missed something but I am going to bed. sorryComment

My last post in this thread.... the resources being sunk into this system, by someone who claims to have little to spare, is saddening. As far as I can tell, the only purpose this off-grid system serves is to provide backup power for when the grid goes down. The money being thrown away on this would be better spent on a generator, and some fuel for it. The time spent watching You-tube and interacting on this forum could surely be spent in more productive ways.
Maybe the existing system can be sold on Ebay to recover some of the expense... people will buy anything there.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

Hey just wanted to let you know you nailed it with the fuse bad contact I fixed it and upgraded to a 300A from the old 250A. Aims said it should have been a 300A in the first place.Comment
