[RE-wrenches] Battery Watt hours FLA VS Iron Edison Batteries

[Tom Duffy]

Hi Dana

Two thoughts... how many days of autonomy are they quoting?

If nickel Iron were this magical how come nobody has noticed them for the past 100 years?

Kind regards

Subject: [RE-wrenches] Battery Watt hours FLA VS Iron Edison Batteries

Good Morning All,

I have a charity case client that needs 760 to 900 AHR at 24 VDC. I have installed HUP Solar One Batteries for 20+ years and do not have any experience with the Iron Edison battery. My client went to Iron Edison & was told that 360 AHR at 24 VDC would cover the same AHR as a 760 to 900 AHR in FLA.  I understand you can use the IE deeper typically than a FLA.

Math is math to me & how I have sized [successfully for years] Is there something I am missing or has my client been misinformed?
