Re: [RE-wrenches] Switching to LiFePO4

I don’t want to stray too far off track, but it’s worth discussing how challenging it is to predict which manufacturers will be around in a few years. I know this might be a touchy subject, but Enphase is beginning to offer full off-grid support. While I’m fully aware of the drawbacks of their sys

Re: [RE-wrenches] Switching to LiFePO4

Honestly, that advice would seem to  be true, but the reality is: It is not valid.  Just look at Blue Planet, that was supposed to be a top tier offering.  Solar World?  AEE? Magnum has had serious issues, Outback doesn't answer the phone, SImpliphi takes an attorney to honor their warranty. Ev

Re: [RE-wrenches] Switching to LiFePO4

It's expensive, but I second Jerry's recommendation. With three subarrays, you should look at the Sol-Ark 15K with three MPPTs. The wiring is so clean with this inverter in most circumstances, even on a retrofit. I am getting more and more comfortable with EG4 LL batteries, mostly out of necessity

Re: [RE-wrenches] Switching to LiFePO4

Jerry, Re your advice to never get startups or small manufacturers as so many disappear and now you are stuck, I guess we should stick with the big well-established manufacturers, like Outback, Magnum and Blue Planet, right? As you would say, fun times... Allan On 9/17/2024 10:58 AM, Jerry Sha

Re: [RE-wrenches] Switching to LiFePO4

Dave, I would suggest stepping up to 48 nominal, fortress 18.5, battery 12 or 15 k solark inverter, re-wire the array to single or dual string, make the wiring in the home capable of 240, this usually requires main panel re-work and set up the monitoring. Batteries are like replacement heart valves

Oops... I haven't had enough caffeine this morning. This is supposed to be in "open" not closed loop. Sorry about the 2nd email. If you have parallel LFP batteries that are not connected in *open loop* communication, make sure you balance them periodically, at least every 9-12 months. Failure to d

Re: [RE-wrenches] Switching to LiFePO4

There are 3 sub-arrays. * 550W on a TriStar MPPT * 800W on a OutBack MX-60 * 1,200W on MidNite Classic 200 From: RE-wrenches on behalf of Dana Orzel via RE-wrenches Sent: Tuesday, September 17, 2024 11:54 AM To: RE-wrenches Cc: Dana Orzel Subject: Re: [

Re: [RE-wrenches] Switching to LiFePO4

I have found that some of the older Outback FX, MX, and even some older FMs don't like how the voltage rises; this can cause them to shut off charge prematurely. I have found that the products made in 2008 and newer can be configured with some tweaking to make it work, but the Lithium battery must

Re: [RE-wrenches] Switching to LiFePO4

I always read that lithium batteries were not compatible with Outback FX inverters... something about their limitations on voltage parameters. Todd https://forum.outbackpower.com/viewtopic.php?t=17565 On Tuesday, September 17, 2024 8:42am, "jay via RE-wrenches" said: HI Dave, A whole

Re: [RE-wrenches] Switching to LiFePO4

HI Dave, A whole new world. I didn’t realize how expensive the backwoods are, wow. There are many out there for around $1200 but not a lot in 24v. I have used many of the EG4 LL batteries, which at this point is one of the larger brands. I greatly prefer and only recommend batteries that have

[RE-wrenches] Switching to LiFePO4

Wrenches, I have a nice little rental house here in my off-grid neighborhood that after 40 years is ready to transition to LiFePO4 batteries. I have no experience with any lithium home power storage batteries. I'm looking for advice, so I can avoid mistakes as a rental house with battery problem
