We have used a few of the Genasun up converters on 48V golf carts. They have
worked flawlessly.

Hi Jason, et al.,
Applications in our size range don't come up too often on this list,
so I've been mostly an appreciative lurker, but I'd like to introduce
myself as the contact for Genasun and Blue Sky Energy, (and the
engineer behind the GVB-8 controller in question).
To address a few of the
Jason, Mack, Maverick, Kent and John,
Looks like the Genasun absorb set points are 57.6 right? Were you still needing
this for a LiFePO4 battery option Jason? Maybe they offer a different voltage
setpoint option I’m not seeing? I’ve needed something like this for a couple
applications as well.

Here is just a thought, each module is either 2, 3 or some with 4 strings
within a single module, so you open the junction box remove the diodes and
cut the buss jumpers, reconfigure the box to a single longer string to
multiply the voltage and equally divide the amperage. you will need
Genasun is a very interesting option and it looks like they also have a
charge controller set for 54.2 volts which is probably the right charge
voltage, but it is only rated for a PV max power point current of 8 amps
(maybe 9). Ten amps from a 420 W solar panel might be pushing it too
hard,
That's what I was thinking. Not a MPPT controller... Just a "dumb" booster
that put the voltage high enough for any off the shelf MPPT controller. But
it can't really work like that. The MPPT function need to be at the lower
voltage side of the device I think.

I second the Genasun product line. I've done a few golf cart charging systems.
works like a charm.

I have a Genasun 36 volt charger on my golf cart boosting from
a Kyosera 245 panel (26.9vm 29 voc) on the roof of the cart. Works
perfectly. I'm starting year 12 running this rig with solar only.
I originally had 3 85 watt Sunwize panels on it and about 3 years ago I

It looks like the Boost versions of the Genasun only go up to an 8A
input current rating. However, they have a footnote on the spec sheet that
reads:
"*Panel ratings have increased since we designed the GVB. Although we don't
believe in changing specifications without a corresponding engineering
I considered a 96-cell panel, but the highest watt panels don't compare to
new 72-cell panels coming out in the 400+ watt range. It's a good fallback
position because I might be losing more in the conversion than I am gaining
in the higher power output.

Jason,
Would a 96 cell Panasonic module fit in the space you have available? It
would give you sufficient voltage to charge this battery.

I saw solar charge controller that boosts the voltage to allow a 60-cell module
to charge a 48V nominal battery, like in a golf cart to Lithium conversion. I
think it was a Genasun GVB-8PB-48V-WP. I’m guessing there is a 72-cell version.
Thank you,

There is a company called Genasun that I believe makes a boost solar charge
controller to do this. They are in the marine world and I haven't poured
over their specs but they are worth checking out.
Try looking at
Genasun GVB-8-Li
Good Luck!

Vmp is 40.14V.
It's one of those situations where I just need a lot of battery capacity as
a backup for a specified time period, but it doesn't matter how long it
takes to charge it back up. And I have space for exactly one
