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 for open flames.
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.
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 Charge Controller current and voltage ratings
Refer to charge controller manual for details.
