Like choosing 2x4 at Lowe's. Not that one. Not that one. Not that one.

New 12v 100ah mini LFP batteries triggered my interest. How small can we go? Final dimensions 22 x 21 x 11 and about 120lbs. I could make it a little smaller, but wanted some clearance between the bottom of the EG4 3000 and the ground for ventilation. The breakers are on the back side...

Also a DJBERMPW which is not a mini but for only $168 I had to try. It also passed the capacity test and the load test.

I did a rough test on my power queen mini 100ah premium ii and it passed. I have a redodo mini that just arrived I'll be testing.

6000xp here and just noticed that my unit also did not update the time properly yesterday. I had DST set in the station profile thinking that setting meant that I lived in a state where the time would change automatically. It appears that is not the case. How does the software interpret the...

Yeah, thanks all for the comments (I can't quote them all) but what got me thinking, was that most of us are vulnerable to the quality of our Chinese all in one inverters. Thank goodness they never fail..... :cry:

Note, the width of the battery is not 5.1" but 5.4"

Thanks all for the ideas on how this might be able to work. It would seem that leaving a lead acid starter battery in the loop helps, and being certain that the alternator will never output higher than the LFP battery BMS cutoff voltage also helps. Finally putting wiring a little too small...

The GrenerPower passed the capacity test and the 100a test.

Yeah, I like the fact that they will automatically handle 12V - 48V at 40A. This could realistically put 2000W into 4 Serial 100AH 12V batteries. Such a nice tidy little solar cart. But I want to find people who have tested this out and recommend it.

What is missing from most of your thoughts is how long can you survive if the most critical piece of equipment in your project goes BOOM when the grid is down, and you cannot get it replaced. What happens then? We are all vulnerable to a certain extent.

What is the sweet spot for the SPF5000ES? I see David Poz is quite happy with 2 - Growatts totally offgrid. I was planning to start up with solar and 1 Growatt grid-tie to help me with my AC during sunshine but handle all other loads from the grid. I would add another Growatt, auto converter...

Grind them up, what a waste of perfectly good panels. 975 MW of panels head to the crusher.

These are back to $179 while others seem to be trying to increase the price for 100ah LMP back to $300. It seems that the $200 price might be here to stay. I got one at $168 before Xmas expecting to have to return it. It passed the charging and capacity test and delivers 100a flawlessly.

"permanently" changes everything. Most campers are intended to be mobile. As long as you will never wish it was mobile again, you can do anything you want. Rip everything out and declare it a detached bedroom.

ECO-WORTHY 48V 100Ah LiFePO4 Lithium Battery, 5.12kWh Capacity, Server Rack Battery with Indicator Lamp, 15000 Cycles, 3U Chassis, $900 on Amazon delivered. But the fine print EG4 not mentioned in communication support... "Battery support CAN/RS485, which allows to communicate effortlessly...

I found your very awesome thread after I posted this. I am halfway through yours now....

No, there is only one. (the second one was only temporary to brace the install so you get a prize for finding the hidden gem) This Anderson connector is for adding a second 48v battery pack to give more than 100ah, or to hook 2 of these systems together for 220v split phase.

At least this Redodo mini passes the capacity test. I'll get this GrenerPower tested soon.

or a separate 120v solar AIO for the 120v loads?

If using a Chargeverter, you still need either a autotransformer or an isolation transformer to make a neutral for 120v loads, correct? Does the isolation transformer provide any additional benefit over the auto transformer in this case? You keep taking me down wild and wonderful rabbit holes...

I don't see any confirmation of the mini size. They are showing dimensions that are the same as the older larger battery. Perhaps just not updated the Amazon listing? I wonder if this is the LiTime/PowerQueen/Redodo mini, or the GrenerPower/Cyclenbatt/Lipuls mini form factor, or something...

Wow, those must be special LFP batteries? What amps can they put out for cranking and heating the glow plugs?

Are there other sources of used and refurb panel like SanTan that are recommended by the forum. I find Solar Steals in Yuma AZ and Clean Energy in Ft Myers and SunGold in CA.

The NEC is supposed to be all about safety? You mean they might be compromised? That couldn't be....

I asked the vendor to confirm the dimensions. They came back confirming the height was as listed. Somebody needs to get one and tell us....

I have 3 of these and they are now $135 They are notable in that they are the tiny compared to other 100ah, have low temp charge protection, and can accept 100amp charging. These are features others charge way more for. See Brad Cagle teardown of them on youtube.

You haven't had any problems with displays going dead? Have you set up the Shine wifi communication stick on your 5000ES? Jeff Motes replaced his 5 SPF5000ES with SolArk15K because of these problems among many other.

Of course you are right. You must have amazing discipline. Some of us are tempted with a full truck load of solar panels (350 per truckload) that are going for only a couple dollars per panel. This auction is for 15 truckloads of 350 panels per truckload. Only the first truckload has any...

Communications with your batteries is not required but you need to babysit your system a bit more. For example you can buy 4 12v 100ah batteries and wire in series for a 48v pack. Set your inverter to lead acid mode. All you need to worry about is keeping the batteries in sync. As long as...

Up on top, and upside down (not shown) are 2 PowerQueen / LiTime / Redodo minis, (5.25 x 10.25 x 9) and down below are 2 GrenerPower / LiPuls / CyclenBatt / XZNY mini (5.4 x 9 x 8)

A weight of less that 38lb should be expected as the case can be much lighter. Hope it delivers what you need. Regarding size I don't see the vertical dimensions, but it looks too tall to compete with your Redodo minis

So far there is no drift and no balancer installed yet. I will see how it behaves over time.

Yes, solar is the first place to invest. Then a switch to manually manage the connection that you only turn on at highway speeds. Then I will be measuring amperage while driving to see what is really flowing into the LFP house battery.

Is there any hope?

Mounting LFE 12v batteries upside down makes the connections and wiring very short. It makes the hooking up the batteries on top (the ones that are upside down) more challenging. It also makes the final unit more compact. The PowerQueen / LiTime / Redodo all seem to be made for mounting in...

So the only issue might be start up load to spin up the AC compressor. Thankfully the AC has an LG compressor installed last year. Maybe it will have lower inrush startup loads. Either it will, or it won't

What would you recommend ? Small battery with large amp BMS to allow for this?

Yes, but Santan Solar can't handle 975 MW from these big farms. That's several million panels. We need 2nd life solar at scale.

Yeah, I could, but I want it to stay small and compact. I'll just use a 2 wheel dolly for now until I get some brilliant design figured out.

It seems like LiPuls has a mini in the same box as the GrenerPower. More minis coming???

I must have misread those. I was sure I saw 12 inches. Looks like the LiTime case maybe but not as tall. Perhaps a typo with the dimensions or something new entirely. Maybe someone who has one can chime in with confirmed dimensions?

I am going to try a few in an RV setup where they will be in motion. And I will mount them laying on their sides. Will they survive?

This video seems to go against the current state of advice regarding using the alternator to charge lithium directly. I haven't seen this discussed here (maybe I can't find it) @Will Prowse is recommending a Renogy DC-DC convertor for RV charging LFP from the alternator. Does this guy know...

I never really appreciated what grid interactive was. I understand it a little better now and how the 18kpv and 12kpv are supposed to handle this. What I would like to see is actual war stories about how well this works, and if there are cases where it doesn't work so well. Can the 18kpv...

I just looked at your signature, and see that you have heaps of 5000ES experience. I'm guessing you are using them with auto converters for split phase loads as well in spite of what Will recommends. How well does the 5000 ES scale when daisy chained. Is this difficult to do?

The weight of a 48v server rack battery is over 100lb. Using 4 12v minis we are less than 80 lb.

Looking forward to a review of these new minis. Seems to be a new form factor. Like the LiTime PowerQueen Redodo mini but not so tall.

Yeah, 2 6000xp inverters would be better, but one can handle 95% of my needs. If the grid could handle the 5% without drama that would be awesome. As it stands, the grid can do it all, but I have to manually switch to full 200a grid mode. Poor me ! ! ! !
