Turn the loads off, and connect the load wires to the load
terminals. DO NOT CLOSE THE BREAKER AT THIS TIME.
STEP 8:
Power-Up and Verify System Operation
NOTE:
Carefully observe the LEDs after each connection.
The LEDs will indicate proper polarity and a good
connection.
Close the battery breaker to power on the controller. Watch
the the charging status, and then the three battery state-
of-charge (SOC) LEDs blink in sequence (G-Y-R), confirming
proper start-up. If they do not light, check the battery
polarity (+/–) and battery voltage.
Next, 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 the 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.
Close the load disconnect, 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 MPPT 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 MPPT
AFTER the solar input has been disconnected. Damage to
the controller may result if the battery is removed while the
ProStar MPPT is charging.
AVERTISSEMENT:
Risque d’endommagement
Le ProStar MPPT MPPT 150V SEULEMENT décon-
necter la batterie APRÈS l’entrée solaire a été déconnectée.
Le contrôleur pourrait endommager si la batterie est retirée
quand le ProStar MPPT MPPT 150V est en charge.
• To prevent damage, power-down must be done in the
reverse order as power-up.
