I will have to look that up, that would mean no code violation then. These "manipulate" up to ten amps, so they are a little over 100 VA - means they should be in a raceway? For sure exposed Yes It would seem reason would dictate the intent is merely to protect.

i just let that register

I found 10 x 38 mm fuses at 11 amps for DVMs. Buss and various Chinese manufacturers sell them. I cannot find a DC rated fuseholder. If a fuse just has 1000V rating, is it implied AC/DC? If the fuse holder is only stamped with 600V AC 30A 50kA, why will they not support a DC circuit of...

This is my thought as well. Especially with the control wire on the victron shunt coming with an inline fuse

Very interesting...Thank you for taking the time to reply. Do you think/feel/know, that if the balancers can "shift" up to ten amps, an eleven-amp fuse may be ok?

If you would take the credit, then we would have something to complain about though...

Shouldn’t any control component with dinky little wires, attached to a battery, be fused? We have all 16 LifePO4 batteries (4S4P) now connected to balancers, and it has made a huge difference. So, the Band-Aid for a poor way to do things seems to be helping immensely. We are going to install...

Perhaps these are only half baked? :rolleyes: Those are some thick and dense interior walls!!

We are looking for battery disconnects rated at greater than 48Vdc and 300amps. Also, this says " Solar DC Isolator", I think this means not opening under load?

Once you are qualified to answer those questions....

I finally understand this. We rarely even see lighting, I have never done lightning protection, but I do see how auxiliary ground rods can cause problems if lighting does strike..Thanks for being persistent with this.

These videos helped a ton! thanks

I was more surprised at the number of words you used!!!

I think we have all disconnected or removed something after an inspection.

At least one person may count that, perhaps more, not sure. Wait, if you are asking, do you not count it yourself?

Please know that in some areas, they may have a code addendum, like San Francisco, that may still disallow mixed conductors though the same insulation value.

any 110-26 violations?:rolleyes:

Timselectric!!!o_O

Exactly, the assembled device must be listed.

I believe, even if independent parts are UL listed, the combination of them must also meet UL. The ensuing disconnect/switch would not be a UL listed assembly. Is this incorrect?

I want to move

If the inspector suggests something and there is an issue later, he has become the now irresponsible designer. If you can develop a clear plan of action on paper and perhaps just ask, "will this pass inspection?" before actually doing it and possibly failing, maybe you will get an answer. This...

So sorry, that is now very funny. I did see the little wink after but forged ignorantly ahead with my emoji. Thank you for the correction. I fixed it.

I think resurrecting a topic is fine! I enjoyed reading it all. This title is rather big “How do DIY folks deal with NEC 690.4 (C) - Qualified Persons Only” It can swing from the “who cares about code” group to the “obey the strictest application of every code on earth” group – I do not think...

Can this really be a disconnect ( https://a.co/d/fuCknn6 ), operated under full load conditions – 300amps @ 60vdc? If it is not, but is merely an isolation device, it seems someone could get hurt using one as a disconnect. I complained about it to Amazon, but who knows where that stuff goes...

They do not show a price, but I think these breakers are expensive? Also, they look like they are for the output side of the PV modules, not a 48VDC battery set?

I also doubt that switching it under load would be a good idea, I think just isolation AFTER all loads are turned off. I think there was a thread in the forum on the difference between disconnects and isolation. I can see paying five times more for one you can switch under load.

Working Condition: The working condition for the battery switch is 12V-60V voltage and 0-300A https://a.co/d/fuCknn6

Working Condition: The working condition for the battery switch is 12V-60V voltage and 0-300A Those are not his, but I do remember they are over 48VDC, next time I am up there I will get the data on them

If he wants to monitor the combined output, will this work?

Yeah, he bought his batteries a couple of years ago. I have a feeling if he knew all of the extra time and stuff now going into them..... One person on here said it will be so problematic I may have to live there. Another said to cut the battery tops off, pull the BMSes out and use different...

i saw that right after sending the image, it is stamped right on the shunt, thanks!!

So, major storms and stuff going on...my friend bought equalizers but when I looked them up they say “Active Balancer Lead Acid Batteries Monitor” = MAZAVA Battery Equalizer HXO2 LCD display…. Will these not work on LifePO4? I see designations on some, what do they mean? HX02 (are these Ohs...

Would that be able to do what he asked for, "monitors grid usage" or ties to the grid?

I have seen more than one manufactured "rolling" battery case with the ability to charge via solar or plug-in, used on camping sites, running a couple of appliances during a power outage, etc. I have no idea how fiscally "prudent" they are. It seems neat to have a panel or two when camping and...
