Wrenches; I have run my house on 12 volt NiFe batteries for 3 years now. I
was going to write a long essay, but Kienen beat me to it. It's an
excellent analysis, I agree with each of his bullet points.
All I'll add is that the batteries charge with decent efficiency up to 80%
SOC. To get that

As we are talking about the IronEdison batteries.
I checked their site about lithium and they claim to have a BMS that will
communicate with Outback.
I didn’t think anybody had comm with OB?
Can anyone confirm that?

HI Ray,
I’ll add that they use lots of water requiring lots of maintenance.
Their efficiency is between 70 and 80%.
The reason that the railroad and telecomm have used them in remote applications
is that chemistry doesn’t care about cold or hot.
And given that they cost (95%) almost as much
IE has been good with their LFP and Schneider spread sheet data for easy

I concur with the other writers. They have low charge efficiency, Although

AEE Solar sold NiFe batteries from Russia in the late 1990s. They last a
long time but were hard to use with inverters. A 12 volt pack has 10
cells. Each cell reaches full charge at 1.7 volts so the pack would be at
17 volts. that is 68 volts in a 48 volt pack. inverters turn off for
Charge efficiency is really low, Charging parameters can be hard to get
right, Voltage is not stable under heavy loads, and they are really
expensive to boot. I've never sold them for these reasons, but I have
replaced some sets that customers were unhappy with. They seem to work
OK, only
Hi Guys, I have a potential customer inquiring about installing a pre packaged Iron Edison system.. I recall hearing strange stories about Ni-Fe batteries but don't recall the specifics. I have done a few searches with mixed results.. And have friends advising I run like a Rabbit.. Thought I'd run
