Trace sw4048 on a 36v forklift battery

[SmartLikeTruck]

I got the Trace sw4048 free when I bought some used panels out in cottage country.
My plan for batteries has always been getting a hold of a gently used forklift battery.
I've finally now got a Deca 36v 875ah battery.

Does anyone know if the Trace sw4048 can be tweaked low enough to run effectively on a 36v battery or am I gonna have to find 6 more cells or a 36v inverter?

I'm 1 fuse & holder and a Anderson connector away from digging in myself

I am running a SW4048.  I am using a capacitor bank instead of batteries though.  I run it between 60V and 32V.  I can tell you that running it 36V or so and below impacts the output AC voltage on mine a bit.  I think that although it can be set to run down to 32V, the AC voltage drops a bit near the bottom of that range.  I can tell by the sound of fans and such when mine is getting near LVD.  Now I automatically shed loads as the voltage drops so it is only at night that it gets that low though. 

If you could get even a matching cell or two I think you could make it reasonably functional as the inverter has great flexibility, but I believe you are at the lower limit.  Rich

Traction batteries in a steel case are 24v and up. Adding 24v to 36v would make it difficult to properly charge without going high on the inverter.

At work we found out the hard way that you have to get a 24v forklift stack up to at least 30.6 for a minimum equalizing. That means 45.9v for a 36v stack, 61.2v for a 48v stack, and 76.5v for a 60v stack.

The SW4048 input upper limit is 66v. The safest forklift stack you can operate on the Trace is a 48v nominal.

If you can find a 24v 1000ah traction battery with a bunch of bad cell, you could rewire it for 12v and add it to your Deka.

Okay so I should be able to set it up for light cycling then
 I'll be looking for some matching ah cells to add into the string

I wonder what would be involved in converting it to a sw4024

...when you can get a used SW4024 for a few hundred bucks?
