Hello, we are working on a large off grid setup. I'm fairly convinced we want to go with server rack style LiFePO4 batteries. We need something that is a UL rated assembly for permitting so EG4 and SOK both seem to meet that but capacity is where I'm getting stuck. EG4 appears to be limited to...

Thanks for all the insights! We'll have two cabins on our property (and eventually a commercial building as well that will be fed by a separate solar setup). Since one cabin (or both when we're not living there) could be rented out, I'm thinking it would be beneficial to be able to see each...

Hello, I tried doing a search and didn't come up with too much so I figured I'd ask. Does anyone have any thoughts on smart electrical panels (Span or similar)? I've gone down the rabbit hole and have to say I'm not leaning either way in particular. Since there's not too much on this thread I'm...

So I'm trying to really nail down a decision on this as it seems to be the final item to decide. I think i'm convinced we want to go LiFePO4 but the UL certification requirement is making me question what we should get. Since EG4 and the like are not an option, I think I'm between ARK Lithium or...

This is exactly the reason that I am considering them. They are between price points of EG4 and something like simpliphi etc. and the entire battery is UL certified unlike all the others that just have UL listed cells so they are a real contender! Unless anyone has any other option I should...

This seems like an awesome resource you're developing, already started going down the rabbit hole of data you've compiled! Seriously, thanks for sharing!

Hello, sorry if this has been addressed before, I tried to do a search but wasn't finding what I need. I'm really wanting to install server rack style LiFePO4 batteries and want some input. It seems that even for an off grid install in our area, the batteries need to be UL certified to get a...

Thanks again for all the help on this everyone, I think we're narrowing this down and am down to component questions at this point. 1. I'm still leaning toward the LiFePO4 batteries from EG4 but wanted to get thoughts from anyone. We were initially quoted around $18100 for (8) 1600 Ah 6 volt...

Thanks for all the help, I thought it might be helpful to include our current site plan for the project to give a better idea of where everything is located on the property and give a little more context!

I actually really like this idea, I'll have to get a cost for running smaller wire to each site but I can't imagine that would be anything too great. So if I'm understanding correctly, you are saying to run the MPP 6548 without direct solar correct and just have it continously trickle charge the...

Thankfully we have some space between the main facility and our septic leach fields that would work well for solar. Close enough where people can see them if they are interested but not so close that they are right next to their site.

Thanks so much for all the feedback, I think off grid makes the most sense and it gives us something extra to educate guests on which is cool as well! I've already planned in a small mechanical room that we will use to store all equipment, the water heater and some cleaning supplies in each yurt...

Yes, thanks again, for some reason I never got a notification of your response but thanks for putting all of that together! It may take me a minute to piece it all together in my head but definitely makes sense to run 240V!

Hello, thanks for taking a look at this and providing your thoughts, much appreciated! Grid power is available but it's quite a distance away and we were quoted at 75k-100k to bring it in. We were planning to have everything at 110V in the yurts but are open to any suggestions. By "main...

Thanks for all the help, this gives us an idea of the range of what we are looking at so we can determine what path we want to go. Any thoughts on the equipment?

Totally new to all of this, where does the 4800 feet come from? Thanks for all the help!

Thanks for all the help and sorry for the confusion on that! Also, this may be a dumb question but if we had a system that output 240V, could we use that to minimize amperage and then convert it to 120V after?

Hello, yes, that was the total we calculated for both yurts together. Also in the calculations, that is with everything we plan to have turned on.

We could likely put a powerhouse in the center but I'm not sure of the additional cost of the additional building. We were assuming that because we are already adding a new main building, it would be less expensive to add square footage in that, especially because that facility requires more...

Correct, we do not plan to use 240V.

Hello, I would think 400 feet would be safe. I'm assuming we will extend enough power for both yurts to the first and then when we build out the second in the future, just extend from the first unless it would be easier to only do the first and then extend a new line from the main facility when...

Hello, the yurts will be 50-100 feet from eachother and the closest one is about 300 feet, maybe a little less from the main facility. Again, we will be building out one of the yurts first and then the second in the future but the total shown in that spreadsheet is for both of the yurts...

Hello everyone, I've asked a few questions on here and have had some very helpful advice and have learned a ton so thank you. As we're starting to finalize our off grid solar design, I wanted to ask for any input as it would be tremendously helpful. We are designing a property that will have two...

Great information, thank you so much! One more question that I keep thinking about. In Arizona, it's mostly sunny, I definitely don't want to tremendously oversize the battery bank (expensive) and obviously cloudy days are what we really size these for (days of autonomy and assuming that all...

Has anyone heard of these Lion Sanctuary 8k All-in-One units with 13.5kwh batteries? It looks really nice and I heard it is a similar inverter to solark but may have potentially more limitations with amount of batteries connectable and with the number of units that are paralleled although I'm...

Hello, Thanks for the thoughts! We're not exactly going for remote, we're about 10 miles from town with no existing electrical service so everything has to be off grid. I know we have a lot going on but we will have two higher end yurts go up first and then we will be building out a campground...

Not sure if I'd say propane is cheap, not nearly as cheap as natural gas typically is but propane would be the only option in that way. Due to fire restrictions being present for a good chunk of the summer, we're already going with propane fire pits at each site so propane water heaters seems to...

I lived in show low for one year and my parents have been up there for I think 12 years now, great area! We'll be quite a ways west, just north of williams, elevation is very similar to show low and so is the weather. There's a lot of people who don't have AC in those areas but I'd like to add...

Haha, I totally understand, for running a short term rental, it may be worth ordering something like this and just seeing. I should probably assume the 500W at a minimum though to be safe! At the end of the day, it's still an "off grid" accommodation and someone may just be happy to have a hair...

Here's a link to the one I was looking at, theres a few others out there as well but this one definitely seems nicer wkth efficient loads and according to the marketing a pretty good battery. It's showing 120wh battery and 4 hours to charge so that would make it a 30 watt charger I guess. For...

That looks like a very interesting idea, might have ti research a bit more before I just end up with propane instantaneous!

That sounds very intriguing! How exactly is yours setup electrically? I believe I've seen some all in one's that specifically have a separate port for excess solar energy to go to one appliance, seems ideal for this. Say the inverter is rated for 6000W output, what size heating coil would you...

I haven't seen anyone running multiple homes on one system but I'm assuming it can be done. Maybe it is just easier to have separate, just trying to simplify the amount of spaces I need for solar since everything will be ground mounted. Fortunately for the electrical system on the campground...

Thanks for the reply! I knew the hair dryer would get brought up, normal hair dryers were causing me stress until I found some options for battery powered that we would likely provide. Regarding SEER, that would be for almost ideal testing conditions and would likely operate at lower efficiency...

Hello Everyone, Thanks in advance for any advice you have, I eventually overanalyze everything and I feel like I'm not really making much progress so I'm turning to the forum! We are developing a piece of raw land to have two 24' diameter yurts that will be fully off grid. I'm trying to figure...
