Safety Precautions
1. Read and understand this instruction manual before use. Always keep a copy of this
manual handy in a convenient location. A pocket is provided on the padded protective
bag for storage of this manual.
2. To reduce the risk of injury, charge only 12V lead-acid batteries or GEL batteries. Other
battery types may be subject to explosion, which can lead to personal injury and
property damage.
3. Always operate the solar panels in a well-ventilated location. Batteries emit explosive
gases, which can be ignited by a spark, cigarette or naked flame such as a cigarette
lighter or matches.
4. Make sure the voltage of the battery being connected is the same as the output voltage
of the solar controller.
5. Make sure the batteries are connected with the correct polarities (positive pole to the
positive pole, negative pole to the negative pole).
6. The battery must be removed from any vehicles when being connected to the solar
controller.
