An inv erter ta k es direct current ( DC ) from your ba tteries a nd turns it into a lter-
na ting current ( AC ) , ex a ctly like y ou us e a t hom e. I t a ls o ta k es a lterna ting current
when y our m otor coa ch is connected to s hore power a nd tr a ns form s it into direct
current to recha rge y our ba tteries .
T here a re two m odes of opera tion a s s ocia ted with a n inverter/ cha rger:
I nverter Mode:
Direct current ( DC ) from the vehicle’s ba tteries is tra ns form ed into a lterna ting
current ( AC ) for us e with you hous ehold electrica l a pplia nces .
C ha rger Mode:
Alterna ting current ( AC ) is ta ken directly from s hore power ( or other AC s ources )
a nd pa s s ed directly to your hous ehold a pplia nces . At the s a m e tim e, the incom ing
AC is a ls o converted to DC to recha rge the v ehicle’s ba tteries .

T he R D S eries inverter/ cha rger ca n power a wide ra nge of hous ehold a pplia nces
including s m a ll m otors , ha ir dry ers , clock s a nd other electrica l dev ices . As with a ny
