Ok we seem to be cross talking here the amps is rated on the output voltage. Yes they do have a max input voltage as well, but the max amperage is with the output voltage. This it handles more inout wattage at higher voltage on the out put ( battery ) side.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment

MOD Note. the following is guessing by the poster, and not to be taken as truth for your panels. You should
make note of the specs on the sticker on your panels, and what the values are:
Voc ___
Vmp___
Isc___
Imp___
The 44 Volts you mention , likely is Uopencircuit Uoc ,
not the Umaximumpowerpoint Umpp .
Sounds like early 72cell panels .
But that Uoc is the important one to get maximum allowed panels per string ,
and the Umpp is the important one to feed the battery .
48 V battery will need a range of 54 to 60 Volts to be feeded ,
and if the Umpp would be at 30 Volts , two in series would feed
a 48 V battery .
For a 24V setup , one panel per string would suffice to feed that battery
if Umpp at 26 to 30 Volts .
Tempetature coefficient needs to be included in Uoc math !
