installation Sequence
note:
The controller uses internal MOSFET based
reverse current blocking for night-time
battery discharge prevention. This allows
much lower losses as compared to Diode
based blocking. Hence, it is not necessary
to provide external Blocking Diode.
Pleaseinstallthebattery,solarpaneland
the loads in the following sequence:
1. Connect the black wire marked “bat
Neg”(4)totheNegativeterminalof
the battery
2. ConnecttheNegativeterminalofthe
battery to earth Ground for protection
against lightning
3. TheBluewire(7)isconnectedas
follows depending upon the type of
battery used:
• Forwetcell/floodedbattery:
Connect this wire to the black
wiremarked“BatNeg”(4).This
willsettheAbsorptionvoltageto
14.8VDC+/-0.2VDC
• Forsealedbattery(AGM):This
wireisNOTconnected.Insulate
this wire with insulation tape .
ThiswillsetheAbsorption
Voltageto14.5VDC±0.2VDC
4. ConnecttheRedwiremarked“Bat+”
(3)thePositiveterminalofthebattery
througha32V,10Afuse(8).Thefuse
should be installed as close as possible
tothebatteryPositiveterminal.The
fuseisrequiredtopreventburning/
melting of the battery wires if there is
a short circuit anywhere in the portion
of wire between the battery and the
controller. Please note that current

5. Connect the black wire marked
“Load-”(6)totheNegativeterminalof
theDCload(DCLamp)andtheWhite
wiremarked“Load+”(5)tothePositive
terminaloftheDCload(DClamp).

on before the solar panel is connected
to subsequently check if the controller
has been connected correctly and is
working(SeeStep7)
