Re: [RE-wrenches] 24 volt LiFePO4 Battery options

Hi Dave, Howie, Et al, With one brand of Li batteries we sell (EPS), if any part of the BMS system fails, you can turn the battery power on manually and continue to function until the repair is made. All the BMS components are external so it is very serviceable by tech or user. Having a spare

I believe that the Unigi II series of cells also has a nano carbon line. Contact Doug Laningham (dlaning...@mkbattery.com) cced above On Sep 27, 2019, at 8:14 AM, Mac Lewis wrote: > > We've installed quite a few GS Nanocarbon batteries and these are available > in 24V. 5000 cycles to 70% DOD

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

We've installed quite a few GS Nanocarbon batteries and these are available in 24V. 5000 cycles to 70% DOD (we usually shoot for around 50% DOD). http://www.gsbattery.com/renewable/renewable-energy-slr-series/ No problems thus far. Not cheap but very high quality. On Fri, Sep 27, 2019 at 3:42

Howie and Allen, I used 5 Simpliphi 24v to replace 24 L16 wet cells. He wanted to keep his old Bergey 850 which I had rebuilt for him a few years ago. He has two VFX3524’s in a Flexware 500 but we are running just one to keep idle loads down. We did have one incident where the batteries

Howie, I’m fully in your court. Just today I replaced 2000 pounds of 18 year old HUPs with 1800 pounds of... HUPs. It’s a full rebuild of a 24v system from the mid-80s, and the scales on a system that vintage couldn’t justify a 48v system. I have asked Blue Planet more than once if they plan

You might also look at https://www.cdtechno.com/pdf/lit/12_1137.pdf Which is using nano carbon, for 3000 cycles to 50%. Other battery companies also have carbon/lead at up to 4000+ cycles for VRLA, and Rolls has 4500 cycles for flooded, both at

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

My 2 cents are each client is different and if they have been fine on that one set of batteries then do what is in their interest. An inverter is easily replaced. I might also suggest to stay with the FLA and avoid possible issues with LFP. No matter how good they are in many cases, they still

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

Howie Understand but the reality is that inverter is going to fail and then it may be to late to make an upgrade and it will be more costly. You might want to consider Deka Unigyll that can be bussed in 24 volts and changed to 48 volts later. No it's not LI but it's a good solution. Jerry On Thu,

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

I've been aware of Simplifi for some time now, and almost used them in my early Li adoption phase, but moved over to The BlueIon instead for reasons of DOD and cycle life/warranty. I've heard good things about Simplifi as well as Discover AES. Does anyone have any experience with integrating

I get what you are saying Jerry, but this client ( a retiring teacher in a very rural, low wage school district, sadly) has lived very lightly off-grid (1kW solar, 24v Rolls KS21s original batteries) for 18 years years and has no pressing need to upgrade his VFX3524 inverter. I'd rather find a

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

Dollars and sence, drop the 24 volt, BPI is a great battery. Once l show my customers all the benefits of a 48 volt upgrade it wins every time. I am not talking about busses, RV's and one night stands l am talking about off grid homes. On Thu, Sep 26, 2019, 1:53 PM Howie Michaelson wrote: > Hi
