WARNING:
RISK OF ELECTRICAL SHOCK.
NO POWER OR ACCESSORY TERMINALS ARE ELEC-
TRICALLY ISOLATED FROM DC INPUT, AND MAY BE ENER-
GIZED WITH HAZARDOUS SOLAR VOLTAGE. UNDER CERTAIN
FAULT CONDITIONS, BATTERY COULD BECOME OVER-
CHARGED. TEST BETWEEN ALL TERMINALS AND GROUND
BEFORE TOUCHING.
AVERTISSEMENT:
RISQUE DE CHOC ÉLECTRIQUE.
NON ALIMENTATION OU AUX BORNES
D'ACCESSOIRES SONT ISOLÉS ÉLECTRIQUEMENT DE
L'ENTRÉE DE C.C ET DOIT ÊTRE ALIMENTÉS À UNE TENSION
DANGEREUSE SOLAIRE. SOUS CERTAINES CONDITIONS DE
DÉFAILLANCE, LA BATTERIE POURRAIT DEVENIR TROP CHAR-
GÉE. TEST ENTRE TOUTES LES BORNES ET LA MASSE AVANT
DE TOUCHER.
WARNING:
Shock Hazard
A means of disconnecting all power supply poles must
be provided. These disconnects must be incorporated
in the fixed wiring. Open all power source disconnects before
removing controller wiring cover, or accessing wiring.
AVERTISSEMENT:
Risque de décharge électrique
Un moyen de déconnexion de tous les poteaux
d'alimentation doit être fourni. Ceux-ci se déconnecte doit
être intégrée dans le câblage fixe. Ouvrir que toutes les source
d'énergie se déconnecte avant de retirer le couvercle de la
contrôleur, ou accès au câblage.
5.1 LED Fault Indications
Load Over-current
Error Status LED: Flashing red. Battery status LEDs: R/Y-
G sequencing. If the load current exceeds the maximum
load current rating, the ProStar MPPT will disconnect the
load. The greater the overload the faster the load will be

disconnected. A small overload could take a few minutes to
disconnect. The ProStar MPPT will attempt to reconnect the
load two (2) times. Each attempt is approximately 10
seconds apart. If the overload remains after two (2)
attempts, the load will remain disconnected until power is
removed and re-applied.
Solar Short Circuit
Charging Status LED: OFF. Solar input power wires are
short-circuited. Charging automatically resumes when the
short is cleared.
Battery Reverse Polarity
No LED indication, the unit is not powered. No damage to
the controller will result. Correct the miswire to resume
normal operation.
Load Short Circuit
Error status LED: Flashing red. Battery status LEDs: R/G-Y
sequencing. Fully protected against load wiring short-
circuits. After two (2) automatic load reconnect attempts (10
seconds between each attempt) the ProStar MPPT will wait,
and then automatically reconnect the load, once the short is
cleared.
High Solar Voltage Disconnect
Charging Status LED: R flashing. No battery status errors.
If the solar input open-circuit voltage (Voc) exceeds the 120
Volt maximum rating, the array will remain disconnected
until the Voc falls safely below the maximum rating.
Remote Temperature Sensor (RTS)
Error status LED: Flashing red. Battery status LEDs: R/Y -
G/Y sequencing. A bad RTS connection or a severed RTS
wire has disconnected the temperature sensor during
charging. Charging automatically resumes when the
problem is fixed. To resume operation without an RTS,
disconnect all power to the ProStar MPPT and then
reconnect. If the controller is re-started with the failure
still present, the controller may not detect that the RTS is
connected, and the LEDs will not indicate a fault.
