They may well "just work," but not to their full capacity if they dip so low that smart loads start cutting out to protect themselves against low voltage. (Many inverters will refuse to work much below 12 volts.) Ideally, you'd follow a NiFe battery with a boost/buck MPP regulator that is designed to charge batteries from a solar panel, which also has big voltage swings. Such a think will deliver a constant 13.8 volts with an input of between 10 to 20 volts or so. :::: In nature, systems that are immature and growing rapidly, in a situation of surplus free energy, tend to be dominated by competitive relationships; mature ecosystems, in which there is little free or surplus energy, show a high degree of mutualistic and symbiotic relationships. -- David Holmgren :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
