Wrenches We have been doing testing on the Blue Ion over the last several months, we have been using PV, back up grid connected charger, we have CT's on DC in, PV in, Charger in, and Load out, some days we push to three cycles a day, other days 1/2 cycle. The Blue Ion BMU has done well keeping

Re: [RE-wrenches] Li+ Systems Puerto Rico

Test data is almost as important as will the company will still be there! That is why I was unhappy that LG Chem (huge company) has decided not to be a player for Offgrid. Oh well! Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ e-mail

Re: [RE-wrenches] Li+ Systems Puerto Rico

Test data is important. If you check out most Li battery brands, they copy each other: “2000 cycles with 80% remaining.” Like Clara Peller said in 1984, “ Where’s the beef?” One brand of Li battery that we sell, LiFeBlue, has published actual test data for their cells (Topband). At 1C rate and

" I am looking forward to the migration away from Lead Acid in the years ahead! " i gotta reply (off list) to this. as i have said before, i LOVE my flooded lead calcium wet cells. no, they aren't sexy li-ons, but they are proven technology for my grid-tied with battery backup application.

Re: [RE-wrenches] Li+ Systems Puerto Rico

Larryyes those are big claims (8000 cyclces at 100% DOD!) No I don't have the data showing that, nor have I seen it. But the marketing has to be accurate right?! We have installed a few systems with a few more on the books including one at our office. Will be interesting to see if the real

Re: [RE-wrenches] Li+ Systems Puerto Rico

Wrenches With all the size limitations of solaredge and even the SMA system, Outback with the Blue ion has been a very good solution and considering the programability and DC coupling, Outback just works better. If AGM is your thing go with Unigee ll, there is alot more work putting it together

Re: [RE-wrenches] Li+ Systems Puerto Rico

If he does not I do. I think I remember reading HALT testing to get the years. LG claims 6000 cycles at 10% where they shut down. They wanted me to become a dealer but I would rather buy from AEE or Soligent and let them deal with sales tax and duty. The Blue color was a bit weird and the new

Re: [RE-wrenches] Li+ Systems Puerto Rico

Hi Kirpal, “...8000 cycles (20+ years of daily cycling!!) to 100 depth of discharge…” I saw that on their website but there is no substantiating data from real cycle life tests. When Sony introduced this battery, they claimed 2000 cycles at 80% DoD. For such an extraordinary claim, there must

Re: [RE-wrenches] Li+ Systems Puerto Rico

The Blue planet does not get its data into the Outback and Schneider web portals for remote monitoring. You have to have both the Blue Planet monitor and the Outback or Schneider monitor for the inverter data. They are nice batteries but still around $1,000 per usable kwh. Sony sold their LFP

Re: [RE-wrenches] Li+ Systems Puerto Rico

Blue Planet - Lithium Iron Phosphate batteries are a good option for off grid and work very well with the Outback Radian inverters. They are rated at 8000 cycles (20+ years of daily cycling!!) to 100 depth of discharge and can be monitored remotely. The batteries , like in the Sonnen system are

Re: [RE-wrenches] Li+ Systems Puerto Rico

I was in Puerto Rico last week up in the hills helping train with a small-ish off-grid combination systems. What I saw in our training building was a Sonnen system with OB Radian, Four Sonnen Li batteries, some external circuitry (relays, etc) and PV using Enphase inverters running in AC

Re: [RE-wrenches] Li+ Systems Puerto Rico

I live in a Caribbean Island and use off-grid solar with grid as backup when available. We just went through Irma and lost power for three months. I've lived these solutions. I wouldn't use anything other than an Outback Radian for this with a DC charge controller, but finding a good Lithium

Re: [RE-wrenches] Li+ Systems Puerto Rico

Ray, I think your biggest issue may be SolarEdge. They told us the StorEdge unit would not start up without grid power. We had an employee install one anyway on his tiny home. He hooked it up to the grid initially to get it started (in back of shop where house was built). He is not sure how

Re: [RE-wrenches] Li+ Systems Puerto Rico

LG has decided not to allow their 48V batteries to be used for offgrid. The 400V LG and Solar edge is too small to be useful for offgrid in my opinion and no warranty. I would add Discover battery to your LFP list. They communicate by canbus and Xanbus to Schneider XW and CSW gear. It is too bad
