<DIV></DIV>I have several 10 Outback inverter stacks in o-t-g applications and I
use 66kW Prime Power gensets for charging. It is common for me to see a total of
25kW of charging w/low battery V although 18kW is about the average. I feel if
the loads dictate 36kW of inverter power and I can charge at 25kW then
supporting charging and loads could be 60kW plus. Most of these are in tropical
environments and controlling battery cell temps has been my biggest challenge as
I try to balance minimized run time/fuel consumption via robust charge rates and
keeping cell temps below 105 F. This is not easy with diurnal temps about 80F.
Generous battery can spacing and big time ventilation is mandatory in hot
climes. <BR><BR><BR>From the Solar, Wind and Hydro powered office of Jeff
