3.0 INSTALLATION INSTRUCTIONS
3.1 General Installation Notes
• Read through the entire installation section first
before beginning installation.
• 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 fire. Ensure tight connections and use cable
clamps to secure cables and prevent them from
swaying in mobile applications.
• Preset charging profiles are generally designed for
lead acid batteries. Custom settings can be used
for varied charging requirements (see sections 3.2
and 4.5 for details). Note that some battery types
may not be compatible.
• The ProStar battery connection may be wired to
one battery or a bank of batteries. The follow-
ing 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.
• The ProStar uses stainless steel fasteners, an
anodized aluminum heat sink, and conformal coat-
ing to protect it from harsh conditions. However, for
acceptable service life, extreme temperatures and
marine environments should be avoided.
• The ProStar prevents reverse current leakage at
night, so a blocking diode is not required in the
system.
• The ProStar is designed to regulate ONLY solar
(photovoltaic) power. Connection to any other type
of power source e.g. wind turbine or generator may
void the warranty. However, other power sources
may be connected directly to the battery.
• The connector terminals will accept a maximum
wire size of AWG #6 / 16 mm2 (solid/multi-strand)
or #8 AWG / 10 mm
2
(fine strand). Use an insulated
flathead screwdriver, and torque tightly up to 35
in-lb.
• Stranded wires to be connected to the ProStar
terminals should be prepared first 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.
WARNING: Solar and battery fuses or DC
breakers are required in the system. These
protection devices are external to the ProStar
controller, and must be a maximum of 20 Amps for the
ProStar-15/M, and 40 Amps for the ProStar-30/M.
WARNING: All breakers must be properly
rated for wire ampacity, which may require
less than the maximum breaker sizes referenced
above.
