Pole Barn Power

[Cashless61]

Looking for advice. I will be building a 40 x 64 pole barn this summer. Its use will be as storage and workshop. Grid power is over 500 feet away and runs $10.00 per foot (trenched) plus other costs to tie in. I have always loved the idea of solar and wind power. I was researching the concept of powering up with solar or possible hybrid system system since there is a fair amount of wind in this area.
I was looking at the 48 volt Mpp 5000 watt all in one system. My power needs will be for 2 garage door openers , lighting at 440 watts, a couple of fans (200) watts and maybe a forced air propane heater during the winter. Plus some small tools but nothing gigantic.
I saw that the Mpp 5000 unit put out 120 and 240 volts.
Since I,m a beginner at this I could use some advice on doing this before I jump in with wallet wide open.

Thoughts and opinions are welcome

My first thought is that you should try to use DC power as much as possible for the garage door, lighting, fans and heater.

Get a handle on how much power (watt hours for example) you will need on a daily basis, first. Get batteries to supply this need and then panels to refresh this need. Converting to AC current isn't 100% efficient so take this into account for items that must be AC.

Is there a D.C. store that could supply all the things I would need?

440 watts of lighting for 2500 square feet seems like a lot.
get one of these http://www.p3international.com/products/p4400.html
Do you have an 240 volt loads?

Your battery choice will decide how much overnight lighting will last.

One LV5048 can power my entire house about 80% of the time. I have two LV5048s in parallel and have powered everything on in my entire house and still only got it up to 83%.

One LV5048 will not have enough surge to turn on a chop saw(or deep well) but will power a vacuum or fan just fine.
Even though the LV5048 is rated 5000 watts, it can only do 2500 watts per leg.

Once you get the output from the LV5048 into a loads panel, you have 120V and 240V just like any other AC system there is.
I'm only seeing about 1500 watts of demand from your garage max, continuous looks like about 100watts or less.
My inverters just sitting there use about 23 watts.

The big expense is buying or making a 48V battery. That's as little as $1000, and as much as $4000 depending on used or new, assuming LiFePO4 (lithium batteries).

Even with the high upfront cost the Lithium type has a far better total cost of ownership that lead-acid/AGM/deep cycle batteries. However, if this is used like any typical storage barn, you won't really need the batteries to perform on daily use, and regular lead batteries might be a good way to get started. 8 6v Golf cart batteries are a very good option, low maintenance and work fine.

Whatever rating a lead battery has in AH is what you need to pay attention to. You get exactly half of that for usability when you compare it to lithium. That means a 100AH lithium equals a 200AH lead in usable energy.

As for solar panels, I would go with either SanTan Solar on eBay (or direct https://www.santansolar.com/product) or this guy out of Dallas. (https://www.ebay.com/usr/texassolar?_trksid=p2047675.l2559)

I get all my wire and connects from Missouri WInd and solar. https://mwands.com/

I have a few videos of the LV5048, my batteries, and some panels.

Just random videos I make now and then. Instead of writing out all the same information again... Just take a look on Facebook at my about page. ? https://www...

No 240 volt loads yet. Just like the capability of having it. I like the 3 phase 208 concept too. I ,m in the research phase now. Grid power cost jumped up 10% last year. Checking your suggestion Thank you
