WARNING:
Shock Hazard
The solar PV array can produce open-circuit voltages
in excess of 120 Vdc when in sunlight. Verify that the
solar input breaker or disconnect has been opened
(disconnected) before installing the system wires.
AVERTISSEMENT:
Risque de décharge électrique
Le réseau PV solaire peut produire des tensions de
circuit ouvert supérieures à 120 Vdc à la lumière du
soleil. Vérifiez que le coupe-circuit ou l’interrupteur
d’entrée solaire a été ouvert (déconnexion) avant
d’installer les câbles du système.
With the solar disconnect open, connect the solar (PV) array
wires to the PS-MPPT solar terminals. Use caution, since
the solar array will produce current whenever in sunlight. A
solar dis-connnect is a convenient way to break the PV con-
nection when necessary. DO NOT CLOSE THE BREAKER
AT THIS TIME.

STEP 7:
Load Connections
-
see diagram below
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), confirm-
ing 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.
