Making my rockwood mini run on wind and solar

I am adding 200w solar panels and a 500w wind generator and have a 6000w inverter. Want to add batteries Lithium LifePO4 12v.
What to run AC, icebox and all lights o and the microwave and hot water.

Two run 24 hours a day how many amp hours would I need

Need this so I can buy enough batteries

Unless you also pull a second trailer full of batteries, you're not going to be able to run the a/c. Maybe 5 minutes before the two batteries are drained.

On one YouTube channel I subscribe to they had their 5er setup to be able to run the AC and most other stuff. It took 6 Battleborn lithium batteries. So that’s $6,000+ just in batteries. Here are some videos of what they installed.

P=IV

200+500 is 700. An ac unit running is 12 amps ac. That is 120 amps dc.

Or about 1500 watts. 6000 watts is 500 amps dc or so.

Get a second mortgage for batteries! And big wires!

The challenge with running the A/C is that there isn't enough roof space for enough solar to recover the draw down of the batteries. Which means, you *can* run it for a while, but at a certain point, you're going to need to shut it off so you can recharge your batteries so that you can make it through the night with the rest of your usage.

The battery selection is your next decision. The drop-ins come in 12v and 24v configurations but are expensive. The recovered Tesla and Leaf battery packs can be reconfigured but I am hesitant buying a battery that has been involved in a crash. The last option is buying individual LI cells from China and building your own array.

If I was planning for this, I'd consider 24v so that you can go smaller on the wiring between batteries and whatnot. A small part of me would even consider a 48v system. Your deciding factor there will be the inverter(s) and solar charge controller. Their abilities will dictate what voltage you run at.

I'd also be tempted to do this with a pair of inverters, one for each leg of the 50amp service. That way you don't have to worry so much about subpanels and transfer switch/pass-thru capabilities of the inverter. For instance, the Victron will only pass-thru 50amps of service. Which means, you'll have to pick specific things to invert. Where if you go for a pair of charger inverters, you can make everything hot.

But then monitoring your battery bank is the bigger issue.

But, understand that to do what you've requested- you're looking at likely a $10-15,000 investment (if not more if you can't do the work yourself).

The other big concern I would have is with a Mini, are you going to have the cargo carrying capacity for the batteries, inverter, solar panels, and cableing? Even with lithium, all of this adds up to weigh quite a bit.

500w wind generator?

Please post what you are using.

It sounds like it would be easier and cheaper to get a small quiet diesel generator (those exist, right?) and make your own Bio Fuel. You'll still get the green credits this way.

Stating what should be obvious wind generators only work with sufficient wind. Some can be rather noisy. Fine as a supplement but you canít expect power whenever you need it.

Based on the thread title I was thinking along these lines:

An inverter generator would be so much easier and cheaper.

Where would you be mounting a wind turbine that size? Each blade would be about 2í in length.

To run what you plan to run, you're going to need a lot more panels and a bigger wind generator. That equals a lot of weight and a lot of costs.

Just sayin'

You've just defined a formula:
INPUT SIDE (solar/wind) DOES NOT EQUAL OUTPUT SIDE

Batteries DO NOT generate power. They store it.
Inverters DO NOT generate power. They consume it.

I am a big fan of solar, and I've used it successfully for years.

This is the best tool ever for keeping yourself honest on power generation and consumption. https://www.rapidtables.com/calc/ele...alculator.html

You know your loads. So, to keep it simple, you have a microwave that will draw 1000 watts at 120 volts. BUT YOUR POWER SOURCE IS ALWAYS 12 VOLTS UNLESS YOU ARE PLUGGED INTO SHORE POWER OR A GENERATOR.

Using the formula, plug in 12 volts and 1000 watts. You get 84 AMPS. Think about that. 84 AMPS requires wire the size of your index finger. Do the same with all your appliances, whether the 12 volt furnace or the fridge or your AC. Run the numbers and estimate times for power draw.

I nuke 4 potatoes for 10 minutes to cook them through. 10/60 x 84 amps =14 amp hours just for that. Hunker down and do your math. Your intended loads will crush your batteries and you haven't planned even a small percentage of the power generation you need.

My recommendation, plan your NECESSARY 12 volt loads and when you want to use 120 volt loads, use a generator. There are many to choose from to handle any projected load. Run your fridge on Propane.

Your announced plan will lead to a world of heartache and disappointment unless you adapt the plan substantially.

Thanks I plan to use both solar and wind. I have a wind generator that i mount to the ladder on the back now, it does a great job of charging 2 AGM batterys now, I use for 12v things I made some special mounts that consumes about 98% of the vibration. It is a 3000w gets about 1000 to 1400 realistically want to add the solar for the full package. My main goal is running the AC the icebox can run on gas and we dont watch a lot of tv and never use the microwave. I would like to use one inverter that I can plug into the 120v land line connection. I know the inverter will be expensive been pricing them. And I know I can just use a genarater but I hate geting up and putting gas in it. The reason for the AC is we camp in south Texas and it can be in the 100 in the spring and 115 in the summer. The batteries is what is keeping me up I can make the rest work but would like to go with Lithium LifePO4 but that brings up issues with blowing up and fire. Still not 100% sure on there safety. What I like about them it will cut the weight in half.

LifePO4 do not have the same fire/blowing up concerns that you’re thinking of lithium batteries for things like cell phones.

Do the math for how much power you need to store and generate like Jim linked to. See if you have enough roof space for the solar needed.

And, what’s your cargo carrying capacity on your rig?

Can you give more details on your 3000W wind generator. This is something that sounds interesting.

Assuming that the AC draws 12A @120VAC, that would be 120A @12VDC. If running for 1 hour would be 120AH which is more capacity than most people have on their RV's. 10 hours run time, which seems very low for a sunny Texas day, is 1200AH. I'm interested in how this is going to work out.

It's why most people that run AC have a dozen 100AH lithium batteries and a roof full of solar panels...and that's with a large 5th wheel or motorhome!
