Automatic Safety
• Load Short-Circuit: Instant load
Disconnects
disconnect. The LED’s flash in sequence.
Battery must be disconnected to clear
and reset (see section 4.2-6)
• High Temperature: At very high tempera-
tures, PV array first disconnected, then
the load. The LED’s flash in sequence.
Auto reconnect as temperature falls.
• Emergency: If battery is disconnected,
the PV and load are instantly discon-
nected for safety and to protect the load.
Temperature
Battery charging, equalization, and high
Compensation
voltage functions are corrected for ambient
temperature variations.
Equalization
Battery charging is automatically boosted
based on low state-of-charge or elapsed
time.

:
Actual charging setpoints of the ProStar controller
are adjusted for temperature, equalizations, and bat-
tery type. In addition, many delays are built into the
controller. Remember to consider these factors when
working with the controller.

NSPECTION AND
M
AINTENANCE
At least 2 times per year the following inspections and
maintenance are recommended for best controller perfor-
mance.
1. Confirm that the desired
BATTERY TYPE
has been selected
(check green LED).
2. Confirm that the current levels of the PV array and load do
not exceed the ProStar ratings.
3. Tighten all the terminals. Inspect for loose, broken, or burnt
wire connections. Be certain no loose stands of wire are
touching other terminals.
4. Check that the controller is securely mounted in a clean,
protected environment.
5. Be certain the ventilation holes are not blocked.
