• 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 4.7
for details). Note that some battery types may not be
compatible.
• The ProStar 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.
• The ProStar MPPT uses stainless steel fasteners,
an anodized aluminum heat sink, and conformal
coating to protect it from harsh conditions. However,
for acceptable service life, extreme temperatures and
marine environments should be avoided.
• The ProStar MPPT prevents reverse current leakage at
night, so a blocking diode is not required in the system.
• The ProStar MPPT 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 can be
connected directly to the battery.
• With the standard terminal cover, the maximum wire
size is #6 AWG / 16 mm
2
(solid/multi-strand) or #8
AWG / 10 mm
2
(fine strand). When using the Wire Box
accessory, the maximum wire size is #2 AWG. Use a
flathead insulated screwdriver, and torque tightly up to
35 in-lb.
