OPERATION
The PVLC-40MD Charge controller monitors both the battery
and PV panel voltage, if PV panels have sufficient voltage for
charge, and if the battery bank requires charging. When
charging the PVLC-40MD 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-40MD
internal temperature compensation adjusts the charge
threshold voltages for optimum charge of the battery bank
based on temperatures between 0
8
C to 45
8
C. For a complete
chart PVLC-40MD Temperature Thresholds section next
page.
The PVLC-40MD 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 11.3V DC for 5
continuous minutes. If the lighting relay drops out on low
battery voltage or is below 12V at dusk, it will not re-energize
until the battery has been charged up to 12.4V DC.
The PVLC-40MD has ten lighting settings (See PVLC-40MD
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). The
PVLC-40MD also can have an optional 5 or 10 minute max
lighting time within a 30 minute period. By clipping either the
White (5 min) or Gray (10min) jumpers this activates the
max lighting routine.
