3.1 General Installation Notes
• Read through the entire installation section rst before
beginning installation.
• Be very careful when working with batteries. Wear eye
protection. Have fresh water available to wash and clean
any contact with battery acid.
• Use insulated tools and avoid placing metal objects
near the batteries.
• Explosive battery gases may be present during charging.
Be certain there is sufcient ventilation to release the
gases.
• Do not install in locations where water can enter the
controller.
• Loose power connections and/or corroded wires may
result in resistive connections that melt wire insulation,
burn surrounding materials, or even cause re. Ensure
tight connections and use cable clamps to secure cables
and prevent them from swaying in mobile applications.
• Only charge lead-acid or NiCd batteries.
• The SunSaver MPPT Battery connection may be wired
to one battery or a bank of batteries. The following
instructions refer to a singular battery, but it is implied that
the battery connection can be made to either one battery
or a group of batteries in a battery bank.
• Stranded wires to be connected to the SunSaver-MPPT
terminals should be prepared rst with e.g. clamped
copper heads, etc., to avoid the possibility of conductor
strands coming free out of the connection screw, and
possible contact with the metal enclosure.
• Solar and battery fuses or DC breakers are required in
the system. These protection devices are external to the
SunSaver-MPPT controller, and must be a maximum of
22.5 Amps.
• Maximum battery short-circuit current rating must be less
than the interrupt current rating of the battery over-current
protection device referenced above.
