Disconnect all power sources before attempting installation  
Electricity can be very dangerous. Installation should be performed only by a licensed electrician or qualified personnel.


Solar panel safety
Photovoltaic panels generate DC electricity when exposed to sunlight or other light sources. Contact with the electrically active parts of the panel, such as terminals, can result in burns, sparks and lethal shock whether the panel is connected or disconnected.

When panels are connected in series, voltages are additive. Consequently, a system assembled from photovoltaic panels can produce high voltages, which constitute an increased hazard. Do not touch terminals while panel is exposed to light. Cover the panel face completely with opaque material to halt the production of electricity when installing or working with panels 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 flame, 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 or solar terminals may damage the controller.




Do not exceed the voltage and current ratings of the 
GP-MPPT-40 Solar Charge Controller
The total voltage of the solar system is the sum of the open circuit current of the solar panels in series. The voltage of the array is the rated open circuit voltage of the solar panels and is not to exceed 150 volts. 

The system Imp current is not to exceed 40A for SOLAR-AE4 kits and 80A for SOLAR-AE6 kits. If your solar system exceeds these ratings, contact your dealer for a suitable controller alternative.
