No lithium batteries. The fuse would be between the DC power supply unit and the separately fused camera loads.

I'm building a control cabinet for my security camera system, it's all 12 volt (Yes, I know I should have gone POE, but the cameras I had purchased were all externally 12 volt powered), so to save money I went with those and ran my relatively small house with 12 gauge wire and cat5e to power...

You would get many more responses if you did that.

I figured out the problem, the high voltage coil is shorted / broken somewhere, which is why I wasn't able to get continuity from that terminal to anywhere else. That also explains why the magnetron stopped working. Thanks for the help guys.

My system is not able to run my HVAC, so I have a cheap window unit that I keep around for when the power goes out in the summer. During the day I put it in the living room, and at night it goes into the bedroom. It doesn't keep the whole house cool, but it keeps it livable. It's not really a...

Xenforo has all kinds of addom spam filters. I can't find the link for it right now, but there's one that you can try out, it's just slider bars that increase or decrease the sensitivity to inappropriate content/spam based on keywords. The one I'm thinking of is specifically called "showcase...

I have mixed emotions about this. Solar is a good thing, but if it involves taking away public hunting land to get it, I'm not a big fan. I wonder how many panels a misplaced .30-30 shot would ruin. Public lands are already shrinking enough as it is, not to mention the deals they have with...

These are just my best guess based on recollection. I also built this system a few years ago, so prices might have changed. -For a 2p4s (8 cell) 12 volt system- -My BMS was about $100 -10 gauge silicone copper wire was about $50 for the amount I needed (I used multiple conductors run in...

While paralleling fuses can be done, it is not usually recommended. I saw this question answered a while back on here, and somebody demonstrated how the failure of a single fuse can create problems with the others.

I would love to see you test fuses and batteries to their failure points.

I know this comment isn't directly on topic, but another option is to heat with gas or wood. Depending on where you live, wood can be free, and it's relatively inexpensive to heat with propane or natural gas (especially considering they cost of inverter and batteries it would need). I'm able to...

I wasn't able to get any continuity between that wire and the frame, although it's entirely possible that that's why the microwave broke in the first place. If that's the high voltage tap, what are the two tabs underneath of the red wires that are connected to an additional coil for? Is there...

I took apart a microwave, because it's not in my nature to throw anything broken away without disassembling it and seeing how it works first. Don't worry, I have absolutely no intention of powering it up. I'm going to use the copper coils for another project instead. Here's the transformer...

I think it's also worth noting that I have added external fans to every one of my UPS's. The transformers in those things get ridiculously hot, and I'm surprised the manufacturer doesn't have a fan in them. The transformer temps were approaching 150° f, I added the fan, and now it hovers around...

Honestly, without having the board in front of me I couldn't tell you much. The most simple way to do it is to add a diode to the charging circuit. Power can come back to the system, but not go into the battery. However, that only works on some UPS's, others will read the battery at 0 volts and...
