WARNING: Shock Hazard
The solar PV array can produce open-
circuit voltages of up to 60 Vdc when in
sunlight, and this DC voltage is supplied
to the Power Conversion Equipment (PCE).
Verify that the solar input breaker or dis
-
connect has been opened (disconnected)
before installing the system wires.

NOTE: For design purposes, array
should be nominal 12V for 12V
battery, and nominal 24V for 24V
battery. Do not exceed 60Voc

ampacity
With the solar disconnect open, connect the solar (PV)
array wires to the ProStar solar terminals. Use caution,
since the solar array will produce current whenever in
sunlight. A solar disconnnect is a convenient way to
break the PV connection when necessary. DO NOT
CLOSE THE DISCONNECT AT THIS TIME.

Turn the loads off, and connect the load wires to the
load terminals. DO NOT CLOSE THE FUSE OR
BREAKER AT THIS TIME.
STEP 8: Power-Up and Verify System Operation
Close the battery disconnect to start the processor,
and activate the controller’s protections. Watch the
charging status, and then the three battery state-of-
charge (SOC) LEDs blink in sequence (G-Y-R), confirm-
ing proper start-up. If they do not light, check the
battery polarity (+/–) and battery voltage.
The green, yellow or red LED will light depending on
the battery state-of-charge (SOC). Confirm that one of
these LEDs is on before going to the next step.
Close solar disconnect. If the solar input is connected
while in sunlight, the charging LED indicator will light.
Confirm proper connection by observing the charging
LED.
