DIY Solar Blueprints -> DIY 24v System. It's in the pull down at the top.is the page supposed to be back up yet as I can't find it...
Thanks guess I'm just getting old.Just checked, they are there. link:

I am old, and I admit it.Thanks guess I'm just getting old.
Yeah, I used 24-volts in all my boats. I know a fellow in Flordia who installed a 48-volt marine power plant in a 32-foot Endeavor with 300ah at 48-volts in Battle Born batteries. With solar panels on a sunny day ln a brisk breeze, he could get to hull speed with a combination of sail and electric motor on the panels alone.On the topic of 24V being useful or not, it is the second most common voltage in the marine industry. Most recreational stuff is 12V, most commercial stuff is 24V, and dual purpose is 10-36VDC. The system I’m building for my boat will be 2p4s, mostly because then I don’t need converters for anything.
The OP asked for 24v 1kW. I see 24v 2kW and 24v 4kW. Is that all there is AND is that where they were originally located?Where did the web pages go for the 24v 1kW off grid system? I was using that as a basis for my system.
Is that all there is AND is that where they were originally located?
I wasn't sure what the kW size was so I put in the original question "2kW".The OP asked for 24v 1kW. I see 24v 2kW and 24v 4kW. Is that all there is AND is that where they were originally located?
Thanks
Of course 24V is sufficient for many systems.. PLUS you got access to many 24V (trucks) devices without a converter.I'm gonna throw my two cents in and add another vote for the adequacy of a 24v system. I'm off-grid completely and power my home with a 24v based solar setup. I have all the amenities a modern home typically has, and after three years I don't know that I would do anything different.
What you're saying is you can "right-size" each system to its use case. If you're NOT powering a whole house, or something that needs quite a bit of power by itself, then a 48v system might not be indicated. To better illustrate this point, Will wasn't using a 48v system back when he was living in an RV and building up his channel/following. Honestly, I think he has lost sight of his roots a little bit, by all of a sudden abandoning support for the smaller 12 and 24 volt systems a lot of folks are still very interested in...obviously. Then again, maybe he's just expanding his own needs and interests, and that's a good thing.Of course 24V is sufficient for many systems..

It's less complex and thus .. less prone to fail and less dangerous, 24V and feets in water is ok, 48V ... is not.
48V is ok only if power is needed and in a way ... it's more of a constraint to go 48V (imo at least).
Ps : i'm using a 48V system in my workshop and i got small systems working under 12V, a distant wifi camera with their own battery / Pv system, a water pump to automatically transfer water to an other tank, each time..... i used a small inexpensive car battery to build those small systems cause they store sufficient energy for those needs.
Yes that's my point, i kind have the same feeling as you, expanding needs ... is not always good if those needs are not ... "usefull", specially if you are a "source of inspiration" for others.What you're saying is you can "right-size" each system to its use case.

I don’t think any codes require steel boxes for 48v battery, nor conduit for 48v wiring.Ive stuck with 24 volt systems for quite a number of reasons,
1) Im super energy effecient with only device I would need 48 volts maybe...(deep well pump)
2) code.... 48 volts must be in conduit, batteries must be in steel box, all wiring must be in conduit
.........24 volt does not need to be in conduit.....largely does not to be code on the DC side
3) refrigeration 12/24 volt DC refrigerators are common, 48 volt DC refrigeration is non existent
4) energy use......I do not need my 4kw. inverter for anything household except the vacuum and the deep well
.........I do quite well on a 1500 watt inverter I have a very good stereo music system which will rip your ears off on only a few hundred watts....Carver 100 watts/channel runs just fine on Exeltech XP-1100 inverter (which has the least EMI/RFI of any inverter)......yes EMI/RFI is pollution
5) environment......We are trashing the planet at an alarming rate
6) born in the backwoods of Alaska, learned very early how to survive on very little, with the way s##t is going to hell in a hand-basket we all may be in need of downsizing a bunch...
NEC typically kicks in for voltages > 48VDC, which is why things like lawn/garden lighting and so forth is 48VDC.I don’t think any codes require steel boxes for 48v battery, nor conduit for 48v wiring.
Please provide the codes that cover this.
