Advanced Custom Settings options are available with
ProStar MPPT built-in meter models (PS-MPPT-25M and
PS-MPPT-40M).
The High Limit defines the lowest temperature at which the
controller will deliver 100% of the controller’s rated output
charging current. The Low Limit defines the temperature
at which the controller will stop providing battery charging
current. The charge current is tapered linearly from the High
Limit to the Low Limit.
NOTE:
Local meter display setup required for Low Limit <
1° Celsius.
4.8 Inspection and Maintenance
Table 4-6 below lists the recommended maintenance
schedule to keep your ProStar MPPT performing optimally.
WARNING:
Risk Of Electrical Shock.
No power or accessory terminals are electrically
isolated from dc input, and may be energized 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 Életrique.
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 chargée. Test entre
toutes les bornes et la masse avant de toucher.
Schedule
Maintenance Items
2 weeks after installation
Re-tighten power terminal
connections to specified
torque values.
3 months after installation
Re-tighten power terminal
connections to specified
torque values.
Monthly or After Each
Equalization
Inspect the battery bank.
Look for cracked or
bulging cases, and corroded
terminals.
For wet cell (flooded type)
batteries, make sure the
water level is correct. Wet
cell water levels should be
checked monthly or
according to the
manufacturer’s
recommendations.
Annually
Clean the heatsink fins with a
clean, dry rag.
Inspect all wiring for
damage or fraying.
Inspect for nesting insects.
Re-tighten all wiring terminal
connections to specified
torque values.
Inspect the system earth
grounding for all compo-
nents. Verify all grounding
conductors are appropriately
secured to earth ground.

AVERTISSEMENT:
Risque de décharge électrique
Déconnecter toutes les sources d'alimentation pour le
contrôleur avant d'enlever le couvercle de boîte de connexion.
N'enlevez jamais le couvercle lorsque tension existe sur les
connexions d'alimentation ProStar MPPT.
WARNING:
Shock Hazard
Disconnect all power sources to the controller before
removing the wiring box cover. Never remove the cover when
voltage exists on the ProStar MPPT power connections.
