[RE-wrenches] Iron Edison Batteries

[jay]

HI Tom,

They are considered 1.2v nominal. 

Charge range is up to 1.7v per cell.
For a 24v system usually you pull out 1 cell or 19 cells 19 x 1.7 = 32.3v
For a 48, usually 2 or 3 , or 37-38 cells.  

If you use much less, then the voltage swings really low, if you go more the voltage is too high for most inverters.
The Iota isn’t going to charge them up fully with that low a voltage.  But I don’t know if that version Iota is adjustable, many of the older ones had a internal pot you could turn up.

But heck give it a try and play with it.

Continuous load 24/7 is only 365 watts with surges to 1200 watts . My guess is that ___# of batteries ( maybe 32 to 36 ? ) can be wire as a 48 volt system ? Any suggestion on charge controllers - Morningstar or MidNite ? . .? A Samplex pure sign wave inverter 2000 watts at 48 volts and an Iota 54 volt battery charger is my guess that it might be the way to power the load - any suggestions  . Anyone have experience with Iron Edison .any suggestions appreciated !  Gator tom PS : any suggested websites ?
