I am beginning to understand the case for an oversized BMS and undersized fuse/wire to increase system impedance in highly parallel...

As discussed earlier in this thread, semiconductor fuses are simply designed with faster time/current curves. But from looking at those...

I would suspect that in may cases it is simply a misunderstanding of cultures. I just spent the better part of the last two weeks in...

What if someone is using 2/0 wire with 125A fast acting Class Ts and 100A BMS's for multiple (over 5) packs in parallel? How would that...

Perhaps if you were a bit more tactful you wouldn't rub people the wrong way,... there are ways to express your opinion politely and...

Neither a FET nor a contactor can reliably interrupt current beyond ~200% of their rating. Yes, a contactor is better, but the two...

Here in Europe has a 3 Phase System 400V. Single Phase is 230V.

Are those rated for pull-out strength?

Oooh, I know this one: Both! ;) If you are trying to disconnect 50VDC on a 500A fault, a 200A contactor will weld the contacts as it...

Honestly, I had 5 of the 58V-rated ones (clear package) and I thought they were fine, until this House Burned Down thread. The OP...

Victron has this

There are two major types-- helical piers for bearing and things like duckbill anchors for uplift.

Has the OP heard of ground screws? I think you could have saved yourself a lot of money and time, rather than using concrete foundations...

The LPG could be a messed up auto-correct/translate for LPF. The soldering iron could have a battery ignitor. So many fakes out there...

The vaporized fuses used to be Littlefuse CCMR 15, rated "600 VAC or less " no DC rating at all. This was in my shop and happened...

From dianea: ''It was a set of AC 600 volt fuses on a 500 volt DC feed from the panels'' AC voltage is way easier to break than DC...

AIC rating can vary with voltage. Interrupt Capacity 10000A @ 14V DC 5000A @ 32V DC 2000A @ 58V DC...

The DC voltage rating isn't the AIC rating - they are different all together. The voltage rating is where it won't arc over/through the...

No! The limitation is often the ability to break DC voltage (DC rated AIC).

Sure something like PV isolator switch. But if you insist on using fuses/breakers then at least install them inside steel enclosure...
