Greetings Wrenches;
We are designing several systems for Puerto Rico, and while these will
eventually could be grid tied once the grid returns, they will need to
operate reliably in off grid mode possibly for a year or more. What is
everyone's experiences with the Storedge and LG setup? I've
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
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

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 soluti
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 co
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
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 batte
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 b
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 model

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 but
10 matches
