T he R D S eries inverter/ cha rger ha s two m odes of opera tion: I NV E R T E R ( prov iding
power to y our a pplia nces from the ba tteries ) a nd AC ( running from s hore power or a
genera tor) . W henever the inv erter is in AC m ode, it pa s s es power directly to y our
a pplia nces a s well a s recha rges the ba tteries us ing a 3 - s ta ge ba ttery cha rger ( B ulk ,
Abs orption a nd Floa t) . T his a pproa ch to ba ttery cha rging prov ides ra pid a nd com -
plete cha rging cy cles without pla cing undue s tres s on the ba tteries . I nverter opera -
tion is fully a utom a tic.

W ith s ea rch m ode ena bled, the inv erter puls es the AC output look ing for a n
electrica l a pplia nce ( ty pica lly 5 to 1 0 0 wa tts , depending upon the s etting y ou'v e
s elected) . W henever there is no loa d detected, the inverter a utom a tica lly goes into
s ea rch m ode ( s leep) to m inim ize energy cons um ption. D uring this tim e, the
inverter 's green LE D fla s hes ( fa s t) to indica te S E AR C H m ode. W hen a n a pplia nce is
s witched on ins ide the coa ch, the inverter recognizes the need for power a nd a uto-
m a tica lly s ta rts the inv erter
I n v e r t e r M o d e
W henever AC S hore Power is no longer s ens ed, the inv erter a utom a tica lly tra ns fers
to ba ttery power with no interruption to y our a pplia nces . T he inv erter 's green LE D
fla s hes once every 2 s econds ( m edium fla s h) to indica te it is running on ba ttery
power a nd prov iding AC to the coa ch.
A C S h o r e P o w e r M o d e
W henever AC S hore Power is s ens ed, the inv erter a utom a tica lly tra ns fers to the
s hore power with m inim a l interruption to y our a pplia nces .
B u l k C h a r g e M o d e
W henever the inv erter is running on nom ina l AC S hore Power, it cha rges the
ba tteries . T he inverter 's green LE D s ta y s ON ( s olid) to indica te the firs t s ta ge of
cha rging. D uring bulk cha rging, the cha rger s upplies the m a x im um a m ount of con-
s ta nt current to the ba tteries . As the ba ttery volta ge ris es to a s et va lue ( ty pica lly
2 8 . 2 V D C for G E L, 2 8 . 6 V D C for AG M, a nd 2 9 . 2 V D C for liquid lea d a cid) , the cha rger
will then s witch to the nex t cha rging m ode.
A b s o r p t i o n C h a r g e M o d e
As the inverter continues to run on nom ina l AC S hore Power, a nd the ba tteries
ha ve been s ucces s fully bulk cha rged, the cha rger enters its s econd s ta ge of cha rging.
T he inverter 's green LE D fla s hes once ev ery s econd ( fa s t fla s h) to indica te a bs orption
cha rging for 1 - 3 hours depending upon ba ttery ba nk s election ( refer to the ME
S eries R em ote m a nua l) . T he cha rger then s witches to its fina l cha rging m ode.
F l o a t C h a r g e M o d e
As AC s hore power continues , the inv erter 's green LE D fla s hes once ev ery 8
s econds ( s low fla s h) to indica te the third a nd fina l s ta ge of cha rging. T he ba tteries
a re held a t the floa t v olta ge ( ty pica lly 1 3 . 6 V D C for G E L, 2 6 . 2 V D C for AG M, a nd 1 3 . 4
V D C for liquid lea d a cid) a s long a s AC is pres ent a t the inverter 's input. Floa t cha rg-

B a t t e r y S a v e r M o d e
T M
D es igned to k eep ba tteries fully cha rged over long periods ( s tora ge) without
dry ing them out. W henever the cha rger is in floa t for 4 hours with no D C loa ds
running, the cha rger will turn OFF. I f the ba ttery volta ge drops below 2 5 . 0 V D C , the
cha rger will a utom a tica lly initia te floa t m ode to return them to a full cha rge.
