Battery Safety
• Do NOT let the positive (+) and negative (-) terminals of the battery touch each
other.
• Use only sealed lead-acid, flooded, or gel batteries which must be deep cycle.
• Explosive battery gases may be present while charging. Be certain there is enough
ventilation to release the gases.
• Be careful when working with large lead acid batteries. Wear eye protection and
have fresh water available in case there is contact with the battery acid.
• Over-charging and excessive gas precipitation may damage the battery plates and
activate material shedding on them. Too high of an equalizing charge or too long
of one may cause damage. Please carefully review the specific requirements of
the battery used in the system.
WARNING: Connect battery terminals to the charge controller BEFORE connecting
the solar panel(s) to the charge controller. NEVER connect solar panels to charge
controller until the battery is connected.
