Great minds think alike brother. A few years ago my wife and I felt like the internet and YouTube was loaded with folks building tiny, sustainably and homesteading...which is incredibly helpful. But there is almost nowhere you can go and experience such living. We started brainstorming and...

Thanks for that. The 20 amps I'm referring to would be the 120v ac load of my home in its entirety. I will be setting up the panel arrays, running them a few feet to a powerhouse where they will be converted to AC and then shipped out varying distances (30 to 300 ft) to each cabin (max 20 amp draw).

I'd like to see what you come up with when you're done. I have 32 of these coming in a few weeks (x4 24v batteries) and I also have in my possession a recently retired farrier/blacksmith stepfather looking for some meaningful projects. Protection for our batteries would fit that description.

Does anyone know the general rule of thumb for determining you fuse size for your battery bank. Will talks about 125 percent of an appliance's rating... But what if it is for your entire system. For example, I will be using a 24v All-in-one MPPT system with an 80a SCC. It will be charging a...

Corona grounded Ecuador plans, for now anyway, hours before a $50k land purchase. Had to settle for Savannah. Thanks again.

I'm not seeing it.

Do you have a quick link to the one you settled on?

So with all of this in mind, which would you say would be the best affordablity/simplicity option if: 1) You did not need low temp cut-off 2) Use a 24v system 3) You want an LCD screen to monitor individual cells 4) Do not care about Bluetooth 5) Want a quick and easy setup?

What is this battery hookup BMS?

That's extreme. I was aware of that possibility, just couldn't find a simple clear example. I'm new that's true. But I've learned a lot lately and have a ton to learn... which I do daily. But I'm thorough and hard working. I wanted to be sure it was not a major no-no. As we all know there are a...

That's helpful. Joey have you seen a video or post showing how to do that?

I'll have to check and see if the LV2424 has an over-current protection setting. Thank you.

What is the C Rating on those things?

Okay, stay with me here. If I have brand spanking new cells, perfectly balanced... connect a harness to each 24v battery set to routinely check and balance with a balancer as necessary...use an A-I-O MPPT set so the battery cutoff at the top and bottom is where you want it for battery...

Do we know what the C Rating is of these 280aH cells?

Completely agree. We are trying to build a bit of a mini-cabin eco-village, that people can come to stay at, for both an awesome experience to learn something about the world and themselves AND to observe how off-grid living looks and feels in real life...rather than just watching videos of...

Yeah baby!!! I never saw a spec on that in the descriptions.

Is that an electric on demand hot water heater or gas fed with an electric panel only?

That's good to keep in mind, thanks for that. Wait, so those 280aH bad boys, at 24v, are rated at over 7kwh?!

I have to look at this. I was acting as if I fully understood what you were talking about a while ago with the Midnight reference. But really I was like, who-zee-what-see?

Good info for me as I design and plan. Thanks, again.

Thanks, Steve, super helpful. Now I am wondering if I should be on the safe side and order more cells to be on the safe side. Can't afford to be off and later want just a few more. It seems like if the shipping cost doesn't go up much with more cells, that's where the incredible affordability...

Steve, I was just thinking...I don't want to get a bank that the rest of my system doesn't really support. Like if I had all this capacity but it would take a week of sun to charge up. That wouldn't be practical for a completely off-grid home. Is it easy to do the math on how many sun hours it...

Ugh, thanks man. So there are better deals to be had. The search goes on.

Amy just gave me a quote for x4 24v 280aH battery sets (32 total cells), to my door, of 3631.44. That would be 907.86 per 24v 280aH battery (Bus and bolt included). Would that not be 3.24 per aH? Based on your figures from January, seems like a pretty good deal for me. Is my thinking and math right?

I just pieced together and bought 3 separate simple 24v systems for some off-grid cabins, that averaged about 2k each. It's doable. My needs and your needs seem darn similar...until you mentioned the heater. I am in the Savannah area and the coldest it gets here ever is 30F, and that just for a...

Okay, great to know, thank you, Jason. Do you think I can just buy the eBay link option I attached earlier this morning? It is only rated for 100a but I will have probably less than 20a. Will their BMS/LCD with wiring kit work, or do I need to try and find all the exact parts you used?

Yes, I know, thats wh Yes, I know, that's why I want to parallel 2 to meet my needs for about the same dollar amount. I don't need their pretty box or their limited BMS... I'm willing with your help to do the work. What do you think about my questions about the BMS that you used but for my...

In fact, would this package work well in my case and keep things simple for me? It is this the same basic thing, correct? https://www.ebay.com/itm/8S-20S-Smart-Li-ion-Lipo-Lifepo4-LTO-Battery-BMS-Protection-Board-Bluetooth-APP/323861328342?var=512884139021

Jason, is it a lot of trouble to dumb what I would need to purchase down for me (in order to do what you did here)? I am doing a return with Tech Direct of my three BYD with pre-built BMS batteries. The AC capacity tests I have repeatedly done on them vary, but the worst are only getting 1.4...

Really helpful, everyone, thank you. Right now, I have 3 separate MPPT systems functioning, really just for battery capacity testing, through my enclosed 24' trailer Big Red. So it seems grounding is being accomplished through the 4 tires. Ultimately, though, the systems are for some micro...

Is it necessary to drive a long copper grounding rod into the ground and connect it to a small system? For instance, a 24v MPPT, connected to max 1500w 110v 20a in the panel array.

I'm building a series of micro cabins and am trying to figure the water design out as well. Is there any reason a Grundfos like yours couldn't be placed in a holding tank (for rainwater harvesting) rather than in a deep well? You mentioned the advantages of the soft start, and the associated...
