Installation

Insert the load fuse, or close the breaker, and turn
the load on to confirm a proper connection. If the
load does not turn on, it could be for various reasons:
the ProStar is in LVD (red LED on); there is a short
circuit in the load (LEDs blinking R/G – Y); there is an
overload condition (LEDs blinking R/Y - G); the load
is not connected, not working, or turned off. After
all connections have been completed, observe the
LEDs to make sure the controller is operating normally
for system conditions. If the optional digital meter is
used, observe that the display is scrolling with proper
voltage and current values. Also, a self- test can be
performed with digital meter units.
STEP 9: To Power Down
WARNING: Risk of Damage
ONLY disconnect the battery from the ProStar
AFTER the solar input has been disconnected.
Damage to the controller may result if the battery is
removed while the ProStar is charging.
• To prevent damage, power-down must be done in
the reverse order as power-up.

4.1 Battery Charging Information
4-Stage Charging
The ProStar has a 4-stage battery charging algorithm
for rapid, efficient, and safe battery charging. Figure
4-1 below shows the sequence of stages.
Figure 4.1. ProStar Charging Algorithm
Bulk Charge Stage
During Bulk charging, the battery is not at 100% state
of charge and battery voltage has not yet charged to
the Absorption voltage set-point. The controller will
deliver 100% of available solar power to recharge the
battery.
