<re-wrenches@lists.re-wrenches.org> Subject: Re: [RE-wrenches] 24v to 48v
upgrade help 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 MandelkornPresident / FounderRenewable Energy

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.
