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 if there are no large surge loads, and the battery and array
are sized large enough. Unfortunately because of the cost, folks seem to
really under size them, which only exasperates the above issues.
There's good reasons this old battery chemistry has not been widely
adopted by the solar industry. It does have its place, and I understand
the train industry uses it because A) they have cheap on grid charging
available, so efficiency doesn't matter, and B) they have telecomm type
loads with very little surge.

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 it by you folks for an update..
Thanks, and Happy Turkey Day.
