Genasun GV-5 Operator's Manual

Safety Instructions!
Carefully follow these instructions.
WARNING – Take caution when
working with batteries. Lead acid
batteries can create explosive gasses.
Short circuits can draw thousands of
amps from a battery. Carefully read and
follow all instructions supplied with the
battery. Use only 12V lead acid
batteries with GV-5-Pb.
Do not short circuit the solar array
when plugged into the controller. Do not
measure short circuit current of the
array while connected to the controller.
This will permanently DESTROY the
controller.
Lithium WARNING – Take caution
when working with Lithium systems.
The Genasun controller uses the CC/CV
charging profile indicated on the
controller. CHECK the specifications of
the battery pack to ensure that the CV
voltage is correct. Further CHECK that
the maximum current (amps) supplied
by the solar array is within the battery
specified design limits.
Lithium BMS WARNING – Genasun
recommends using a Lithium battery
with a Battery Management System
capable of disconnecting the solar
charge controller in the event that any
cell in the pack is outside of itʼs rated
temperature, current, or voltage range.
Failure to do-so may result in injury or
death. Genasun also highly
recommends the use of a BMS with cell
balancing. Cell balancing is mandatory
for lithium-iron phosphate systems.
Installation
1.
Mounting
 The G V-­‐5 c an b e m ounted i n
any o rientation.
 Do n ot e xpose t o w ater.
 Do n ot m ount n ear a s ource o f h eat.
 Mount n ear b attery.
2.
Connect the Solar Panel.
 Connect the solar panel to the GV-5
Panel input. DO NOT connect the
solar ground to your system ground,
your batteries will be damaged
 Note: In the GV-5, the positive
side of the battery is connected
internally to the positive side of the
solar panel.
3. Connect t he B attery.
 A small spark while connecting the
battery is ok.
4. Connect t he L oad
5. No B locking D iodes.
 The GV-5 prevents the battery from
discharging through the solar array
during the night. Blocking diodes are
not required if only one panel is being
used.
