Safety Warning
These are important instructions for model GP-PWM-10-SQ that should be followed during installation and maintenance of the GP-PWM-10-SQ.
Disconnect all power sources
Electricity can be very dangerous. Installation should be performed only by a licensed electrician or qualified personnel.
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.
Wiring connections
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.
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-10-SQ 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 10A. 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.
