Would you be up for posting a link to an example of "5KW of less convenient auto style Lifepo4 at Amazon for about $800 shipped any day"? Curious to see the options you're thinking of.

For me it's adding shipping (~$230) and tax (~$80) for a total of $1477 for one. But they're doing a free shipping over $2000 promotion, so two batteries comes out to $2459 or $1229/each. Pretty good price for a 5kwh battery from a reputable solar retailer.

If it's not rack batteries, you can get much cheaper.
Eco Worthy batteries are cheap and they do have the rated capacity.
From time to time, Ebay will have a 20% off and various vendors will participate including Eco Worthy.
I've gotten their 12v 100a for $200= $160. 4 of these equal $640+tax for 5120wh. Same as the 48v 100a. You can wire these 4 to be 48v.
I've also gotten their 24v 100a for $340 which is $680 for the same 5120wh.
I have mostly all Eco Worthy batteries in my 2 systems.
They have been around for a while so I know i'll get warranty from them.

what are the applications? dc power supplies? ac inverters? i'm curious what 48v circuits are actively used.

It's a great idea i wish we had 48v residential circuits, just curious the commercial applications of this unit

Could I rig 1-2 of these up for a whole house backup? I have AC coupled solar currently.

Same question. new to this whole battery backup stuff, but seems like it should be pretty straightforward?
Yep. To keep it simple you can use a ~3kW hybrid inverter. I use a Growatt SPF3000TL [signaturesolar.com] from Signature with one of these Lifepower4s and it serves rather well. Not only as backup power and a buffer for not having to run a generator continuously for an extended outage, hybrid inverters can charge your battery/batteries from solar input as well.

I'd always figured I'll end up with another Lifepower4 or two, but not just yet - right now I'm in the market for a water resistant 12V LFP to expand my EFDelta 2's capacity. For the hybrid inverter setup - one 5kWh battery might not be quite enough to get through a full winter night with a furnace's ~400-800W blower going - at least without firing up a generator to top off.

That said, I'm considering 'upgrading' to a Victron MultiPlus II 3kW / 48V inverter because they're UL listed and should be 'good to go' in a house, especially for 'off-grid' use, same with these batteries. Lower consumption @ 11W idle with the AC inverter on vs ~45W for the Growatt (FYI). They're intended/marketed for use as a "whole house" UPS solution and can be used for load shifting to off-peak billing hours. I'll always just have mine fed into a generator inlet (into a transfer switch) to keep them at least semi-portable. Planning on building it the Growatt + Lifepower4 in to the bottom of a tool cart for a portable power pack.

Has anyone tried like 4 series x 4 parallel (16 total) of these for a large 48 volt inverter?

These are 48v, not 12v

oh, this posted to the wrong thread, it was for the 100ah 12 volt batteries which I was thinking of buying instead of this.

Some places don't charge tax and have decent freight shipping.
