Most Popular 48V Offgrid Solar Battery: New Version Released! And It’s Actually Impressive..

For less than $1,000 more than what this battery is selling for, you can purchase an easy to assemble, DIY LFP battery kit with triple the capacity (over 15 kWH) with a name brand BMS with Bluetooth, active balancing, and a full suite of com ports and grade A EVE cells. So I agree, I don't understand why people are buying this thing?

Great update and video! Do you have a discount code for those looking to purchase a turnkey setup or battery and inverter at signature solar to share? Keep up the great work!

I was a bit surprised to hear your appreciation (in comparison to the older model) of the 6,000 cycles to 80% DOD. The older batteries said 7,000 cycles to 80% DOD. I don't know if they just changed their testing regimen, or something. I also don't have any other information to validate if this is a real difference between the two.

That said, I also had no idea that the new batteries were so good in so many other ways; that's amazing to see. I just recently got the older model, probably a month before they released the new. :P But if they really will last as long as originally projected, it's probably fine, haha.

Man do I hear you on the crappy, non-flush screw situation though. That was really disappointing when I was installing them.

I think Sheldon did a great job on explaining this product 😉✌️

Great vid! You mention that you like vertical batteries better. Which one would you recommend? I am looking for 48v 200-300 ah. Thx!

Chuck Cassady uses these batteries with Victron systems in his bus builds to run mini splits and the internal electrical systems. That's probably better for many reasons in a school bus.

You are the best

Will I would love to see a bit more about the large batteries ✌️👍👏

Great.. bought 2 of the old one in the last couple of months

We have to rely on server rack options as we live in Hawaii and just shipping them back and forward for service takes 5 month for each. It is nice that they make this large vertical version but in case of a failure (as we just experienced) I can take out one of the six in my rack send it back for repairs (takes 5 month) and still have electricity in the house. Now with the super heavy power pro wall mount as an all in one vertical battery that will never work. I had a hard time with Signature Solar to even get this one battery back to them for repair during warranty because of our location

I have been watching your videos, and I've been reading the DIY forum. But I never knew the forum was yours.

Great job man.

Gotta do the Vatrer server rack! 😁

A battery expert / scientist once said that LFP cells should be upright the first 2-5 cycles so that small bubbles can rise and excape. So you get 8000 cycles instead of 4000-6000 that is the reason why upright batteries have an disadvantage to server rack batteries when used as intended

I can't get mine to communicate with the EG4 3000. Have four of them.

Very impressive

If I already have two server rack batteries can I add a vertical battery to the same battery bank?

I doubt anyone is going to swap out their old ones for these, I am happy with the six old ones I have. I use window ACs and over night I still have 70% SOC in the morning. Also I think the old ones have 7000 recharge cycles. I would guess you will get many more cycles just discharging 50% or less. I do enjoy these videos, I copied his setup when installing my EG4 6500EX system.

It would be amazing if someone can make a portable battery system with the 6000XP and this battery. One which is as compact as possible, has wheels and a handle to move around and one that is somewhat covered up so it won't look too awkward pulling this around in public lol. That would compete with Anker solix f3800 (for the 6000w output). Benefit of using the larger 600XP instead of a smaller inverter would be that later we can use the 6000XP system for home system (or part of a home system hooked to another 6000XP). So in the rare event you need portable power, just unhook the one portable 6000XP (with this battery) and let the home run on grid until you hook the portable 600XP back on? Is that even possible with some sort of quick disconnect cables? I am new to all this but very fascinated. Not a home owner yet so a portable version with 6000XP inverter would almost set me up to do a home system if and when I own a home and use solar. Until then it would come in handy for emergency power when we lose power. Danm this comment turned out much longer than I anticipated haha.

High voltage is better

I think the reason the rack one is popular is for density in a small space. I'm planning my own solar deployment, and I'm intending to use a 10 x 16 building that I converted into my office as a power house/datacenter. I only have so much wall space, and I could probably only fit four of the wall mount batteries comfortably. Comparatively, I could do probably 3 x racks of these server mount batteries, (IE 18 of them). I do run servers as well in this office, so I'm really planning to have an IT server rack, and then 3 battery racks. Wall mount the inverters, and connect them to the racks. Definitely agree that the wall mount ones are more aesthetically pleasing.

The battery terminals are huge compared to the original models. I will probably add 6 more of the new ones to complete my battery bank. 

Edit: My battery bank of the originals have the fire arrestors as well.

Hey will, what’s your thought on using Chins batteries and making a large battery bank out of them. Like a 4s 4p configuration. The 280ah chins 3580wh, i have seen for as low as $414 on Amazon.
