LED lighting, propane everywhere possible, brought the load way down.

From what I understand, the problem with running a 12V system is voltage drop, should you try and centrally locate and distribute, plus you have the issue of setting up a "fuse box" that a building inspector would sign off on (an that would be safe).
That's not all that impressive. I run my house off a 6.5KW generator when the power goes out. The only reason I'd keep a main line to the grid is because my genny doesn't like my deep well pump at all. It still takes it like a champ when it kicks off though.

I wanna see someone live in South Georgia in the summer with no AC
98* 90% humidity

A few years ago I looked at some property in north Ga that was impossible to run electricity to

The land was totally surrounded by USFS and there was a road easement in across the FS land the FS would not allow utility lines overhead and 3 miles of underground cable was cost prohibitive

I discovered that kerosene was better than propane
And you could even buy kerosene water heaters
Looks just like a propane one but runs on kero

Using solar for electricity is easy until you need a AC unit or clothes washer or dryer

Although using a clothesline to dry clothes is easy unless you have 90% humidity. Then your clothes just mold on the line they don't dry

We did it on one project. Minisplit did the job. Place was only 800 sq.ft. tho. Temps. easily hit 102+ there in the summer.

I have an 8'x12' room in my garage. I'm going to take everything out of it, and turn it into a "go-to" room in case of emergency. It won't have AC, but I'm putting in a natural gas heater.

You know how the internet is, google something for your cat, and I'm sure you know the results you'll get. Google "off grid solar design", you'll get some prepper sites. I'm not ready to say I'm a prepper.

Look at "images", and "videos".

Here's a couple of videos I watched, and learned just enough to be dangerous.

Tin Hat Ranch (prepper site)



Pretty clear information in this vid. He also has a great parts list you can print for design ideas and reference. I lose it at the end when the dude starts talking about the lord jesus Christ.

So far, my design is from copying what I've seen;

600W - 24 V panels
60A MPPT charge controller (room to grow)
24V 2000W pure sine inverter
(8) 6V-220ah golf cart batteries - which when connected in series/parallel will give 24V and 880ah.

I think!

That should come out to 440ah. You would have two banks, each of four batteries in series, 220ah per bank. I think

Am I adding incorrectly?.....

Seriously, let me know. I am totally the wrong engineer!

series/parallel/series (?) 4 banks of 2(?)

Not sure. The picture ^ is right.

So, you can wire it two different ways:

1) 2 batteries in parallel for 6 volt/440 ah, 4 such banks wired in series to get 24 volt/440 ah, or

2) 4 batteries in series for 24 volt/220 ah, 2 such banks wired in parallel to get 24 volt/440 ah.

I have been dabbling with it all year for more of a backup grid zero solution. And then I have it if I ever do a cabin and move the system elsewhere. Lots to figure out and 100 ways to do it.

I got (4) of these 6v batteries for a 24v system. 370 AH. Trojan is a pretty good brand.

L16RE-ac | Trojan Battery Company

An outback hybrid inverter. VFXR3524A 3500W. 120v. Though I do not make enough for and not set up for sell back, it can if I wanted. It has UPS mode, grid zero mode, mini grid mode and grid tie mode. I use Grid zero to use both house and battery dependant on load.

Outback Power Inc. - FXR Renewable Series 120V A Models

So far (10) of these Renogy 100w panels.

https://www.amazon.com/Renogy-Watts-...s=renogy&psc=1

And use a midnite classic charger to bring the power in. It can handle 24 panels in my current 500w series configuration.

MidNite Solar Inc. Renewable Energy System Electrical Components and E-Panels

Also used Midnite Solar's wiring box where all the main breakers and shunt and all reside. Made my own transfer panel with a generator hookup so that I can charge the batteries that way and or power the house if need be.

We are pretty frugal with power anyway so it will take forever to pay back. Water heater is on a timer, runs for an hour a day. Girlfriend likes to dry clothes on the line anyway and barely use AC, Oil heat, so the stove is the biggest consumer really. Water pump is 120v. I can pretty much make it through the night powering full fridge, deep freezer, mini fridge and misc. items and the heat kicking on a few times.

The hardest part is getting the batteries back to a full charge the next day. You need to dial in the panels vs battery usage to get them full charge. It is all programmable with this inverter though. I only drop the batteries to 70% in hopes of longevity and to make sure they get full charge. I do need some more panels really though and just keep adding at my leisure. 4 more batteries would be ideal as well but then I would need more panels to get full use out of them. It is a cycle.

It is nice though to see my meter sitting still if I tone down the usage to minimal.
I am roughly 6k in, but do get to take advantage of the 30% break still for this year. So roughly 4k for a quiet, gas free backup solution "if the sun is shining".

I used 1/2 copper pipe for buss bars on my 12v setup. .2v drop at the furthest point. I just run yard lighting, security cameras w/dvr, router, and anything else that had a 12v wall wart on it. 200w with a good charger that takes up the slack on a single deep cycle.

inspectawhat?

wiring box, couple revisions since pic. Quite a bit going on inside.


transfer switch box, now also have a pipe running to the house with 5 more panels on the roof. There is a 30 amp generator plug underneath. power from house, to and from the inverter all reside here with breakers.


Panels on the garage


What is inside, Inverter, wiring box, charge controller and monitor/programmers. Surge suppresor,


Batteries under the counter on a furniture dolly, all 4/0 wire for connections, now in a box as well.

Voltage drop? Sure. Must be managed.

Inspectors? Nada. Low voltage systems do not come under their jurisdiction - otherwise no one could even set up electric trains.

Just had a conversation about solar stuff today with the old man. He has been educating his self by following Backwoods Solar for about 25 years. He will be putting in a system soon and is excited about how the tech has evolved.

Solar Panels & Micro-Hydro | Off-Grid Solar Power Systems


He plans on using a generator to top off the battery banks when needed.

uhh 12kw portables are massive units....

4 solar panels in no way, shape or form replaced a 12kw generator.

Not just 4 solar panels, 4 solar panels plus a battery bank. Screwy said the place "runs on 25 amps", which could mean almost anything. Depending on average power draw, it might run on 4 panels.

Means I did the calcs for the building dept. and that's the results we came up with. There's some pretty "standard" calculation spreadsheets you can follow.

Good description (long) of the process:
Dwelling Unit Calculations

This house had all gas appliances (stove, refer, furnace, dryer), so most of the electric load was lighting and kitchen/bath outlets.


No A/C neither.

Now, the Yurt we built (625 sq. ft.) had roughly the same load but DID include A/C. We were running a minisplit in there.
