OPERATION
The PVLC-15MD Charge controller monitors both the battery
and PV panel voltage to determine: 12V or 24V DC mode of
operation, if PV panels have sufficient voltage for charge,
and if the battery bank requires charging. When charging
the PVLC-15MD cycles the charge relay every 4 minutes to
re-verify open circuit PV charge voltage to avoid discharging
the batteries through the PV panels when low light conditions
occur. The charge re-connection time is varied by the micro-
processor to optimally reduce the charge rate for nearly or
fully charged batteries. The PVLC-15MD internal temperature
compensation adjusts the charge threshold voltages for
optimum charge of the battery bank based on temperatures
between 08C to 458C. For a complete chart PVLC-15MD
Temperature Thresholds section next page.
The PVLC-15MD Lighting controller monitors the motion
sensor, PV panel voltage and battery voltage and initiates
the “light-on” cycle when either the motion sensor has been
activated or a dusk voltage threshold has been reached for
dusk to dawn operation. The relay remains energized until
either the time selection is reached, the PV voltage indicates
dawn, or the battery voltage drops below 11.0V (or 22.0V)
DC for 5 continuous minutes. If the lighting relay drops out
on low battery voltage or is below 12V (24V) at dusk, it will
not re-energize until the battery has been charged up to 12V
(or 24V) DC.
The PLCM-15MD has ten lighting settings (See PVLC-15MD
switch - lighting adjustments for timing selections). There is
OFF, 4 night only settings, Dusk to Dawn setting, and 4
anytime settings. Selecting (5) “Dusk to Dawn” on the timing
switch causes the lights to turn on at dusk and remain on
until dawn (subject to the low battery voltage cutout).
