Go Power GP-PWM-30 User Manual

2. Warnings
Disconnect all power
sources
Electricity can be very dangerous. Take
appropriate caution when making connections.
Battery and wiring
safety
Observe all safety precautions of the battery
manufacturer when handling or working
around batteries. When charging, batteries
produce hydrogen gas, which is highly
explosive. Ensure batteries are in a well-
ventilated space, away from sparks or open
ames.
Wiring
connections
Ensure all connections are tight and secure.
Loose connections may generate sparks and
heat. Be sure to check all connections before
using the portable solar kit.
Work safely
Wear protective eyewear and appropriate
clothing during installation. Use extreme
caution when working with electricity and
when handling and working around batteries.
Observe correct
polarity
Reverse polarity of the battery terminals
and array will cause the controller to give a
warning tone. The controller will not function
unless battery terminals are connected to a
battery with proper polarity. Failure to correct
this fault could damage the controller.
Do not exceed the
GP-PWM-30 amp
current and max
voltage ratings
The current rating of the solar system is the
sum of the Maximum Power Current (Imp) of
the solar PV strings in parallel. The resulting
system Imp current is not to exceed 30A. The
voltage of the array is the rated open circuit
voltage (Voc) of the PV array and is not to
exceed 28V. If your solar system exceeds
these ratings, contact your dealer for a
suitable controller alternative.
