Genasun GV-4 User manual

Safety Instructions!
Carefully follow these instructions
during installation.
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.
Do not short circuit the solar array
when plugged into the controller.
This will permanently DESTROY the
controller.
Do not measure short circuit
current of the array while connected
to the controller. This will short the
array, and permanently DESTROY
the controller.
Installation
1. Mounting
The$GV'4$can$be$mounted$in$
any$orientation.$
Do$not$expose$to$water.$
Do$not$mount$near$a$source$of$heat.$
Mount$near$battery.$
!
2. Connect the Solar Panel.
!
Connect the solar panel to the GV-4
Panel input. DO NOT connect the
solar ground to your system ground,
your batteries will be damaged
Note: In the GV-4, the positive
side of the battery is connected
internally to the positive side of the
solar panel.

A small spark while connecting the
battery is ok.

The GV-4 prevents the battery from
discharging through the solar array
during the night. Blocking diodes are
not required if only one panel is being
used.

Inspection / Maintenance
Inspect the controller at least once per year
to ensure proper performance.
•Check for animal or insect damage.
•Inspect for corrosion.
•Inspect for water damage.
•Clean if necessary.
•Inspect the security of all
connections.
•Ensure the solar array does not
exceed the maximum input voltage.
