Aaron,
Ain't nothing wrong with going to 48 volt. It sort of
sounded like you wanted to stick with 24 volt but if they want to
replace PVs too (which it sounded like in your original post), go 48.

All, I will do a load analysis for the 24v loads. I am looking to
get around 800ah of LI storage at 24v. I typically use the larger 48v
batteries from fortress. The space constraints will not allow for a
wall full of small 50ah 24v units. I am not finding much selection of
24v 200ah+ options. Is sounds like most of the advice I am getting is
towards not upgrading to 48v.

Aaron,
It would be helpful to know how many amps are required
to power the 24 volt loads and should we assume the batteries are
toast or nearly so? The brand of inverter?
As Jeff said there are 24V L-ion choices.

Wrenches,
I have a customer with a very old 24v off grid pv system. He
wants to upgrade his array, inverter and battery bank. There are
no options for inverter/chargers over 4000 watts in 24v dc. The
same goes for lithium iron batteries. Everything (of higher
wattage and battery capacity) seems to be in 48v only now. If
going to 48 volts how do I acomodate the few but important 24v DC
loads in the home. Is a 48v to 24v step down converter the best
option? What do you think? Any help would be appreciated. Thank
you.
