6.0 INSTALLATION INSTRUCTIONS
The ProStar is installed in 10 steps. Follow the procedure in section 6.2 for a proper installation
and best performance.
6.1 GENERAL INSTALLATION NOTES
• The ProStar uses stainless steel fasteners, an anodized heat sink, and conformal
coating to protect 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. Do not connect
it to any other type of power generator. Do not attempt to regulate a wind turbine.
However, other power sources can be connected directly to the battery.
• The connector terminals will accept a maximum wire size of AWG #6 / 16 mm2
(solid/multistrand) or AWG #8 / 10 mm2 (fine strand). Use a flathead insulated
screwdriver, and torque tightly up to 35 in-lb.
• Fuses or DC disconnects may be required in the system. These protection devices
are not part of the ProStar controller.
NOTE:
Carefully observe the LEDs at each connection. The LEDs will indicate
proper polarity and a good connection.
6.2 INSTALLATION STEPS
Refer to the wiring connection diagram in section 3.0.
STEP 1: Mounting
Inspect the controller for shipping damage. Mount the ProStar to a vertical surface
(4 stainless steel #8 self-tapping screws are included). Tighten the mounting screws
using care not to crack the plastic case. Do not install directly over an easily
combustible surface since the heat sink may get hot under certain operating
conditions.
NOTE:
Heat sink must be in a vertical position (fins up and down).
Allow at least 15 cm (6 inches) space above and below the controller for air flow.
Install in an area protected from direct rain and direct sun.
If the controller is installed in an enclosure, some ventilation is recommended.
Do not locate in an enclosure where battery gasses can accumulate.
STEP 2: Ratings
Confirm that the solar array and loads will not exceed the current rating of the
ProStar version being installed.
Multiple ProStar units can be paralleled at the system battery to increase the solar
capacity, but do not parallel loads.
