1.1 How Does a Go Power! Solar Charging Kit Work?
The solar module converts the sun’s energy into DC electricity and this electricity charges the battery. The battery stores the electricity, similar to a water tank
storing water. The battery power may be used at any time to operate devices connected to the battery. To stop the battery from being overcharged by the
solar module, a solar controller is connected in between the solar module and the battery. The GP-PWM-10 controller will disconnect power from the solar
module when the battery is fully charged.
Please read and understand all instructions before installing your new product for the easiest and safest installation. Before installing the kit, please review
all diagrams included in this manual. If you have any doubts as to this kit’s compatibility with your RV, please contact your authorized Go Power! Dealer. It is
advisable to retain this manual for future reference.
1.2 Warnings
Disconnect all power
sources before
attempting installation
Electricity can be very dangerous. Installation should be performed only by a licensed
electrician or qualied personnel.
Solar module saftey
Photovoltaic modules generate DC electricity when exposed to sunlight or other light sources. Contact with the
electrically active parts of the module, such as terminals, can result in burns, sparks and lethal shock whether
the module is connected or disconnected.
When modules are connected in parallel, amperages are additive. Consequently, a system assembled from
photovoltaic modules can produce high amperages, which constitute an increased hazard. Do not touch
terminals while module is exposed to light. Cover the module face completely with opaque material to halt the
production of electricity when installing or working with modules or wiring.
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. Work in a well ventilated area
and use caution when making or removing electrical connections. Ensure wires are disconnected from their
power sources when wiring. Do not expose battery to open ame, cigarettes or sparks. Shield skin and eyes
from battery acid.
Ensure all connections are tight and secure. Loose connections may generate sparks and heat. Be sure to
check connections one week after installation to ensure they are still tight.
Work safely
Wear protective eyewear and appropriate clothing during installation. Use extreme caution when working
with electricity and when handling and working around batteries. Use properly insulated tools only.
Observe correct polarity
at all times
Reverse polarity of the battery terminals will cause the controller to give a warning tone. Reverse
connection of the array will not cause an alarm but the controller will not function. Failure to correct this fault
could damage the controller.
Do not exceed the
voltage and current
ratings of the
GP-PWM-10 Controller
The total current of the solar system is the sum of the short circuit current of the solar modules in parallel,
multiplied by a safety factor of 1.25. The resulting system current is not to exceed the amperage rating of the
controller. The voltage of the array is the rated open circuit voltage of the solar modules and is not to exceed
28 volts for a 12 volt system.
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 10A. If your solar system exceeds
these ratings, contact your dealer for a suitable controller alternative.
