Mark PV Controller
DESCRIPTION
The Specialty Concepts, Inc. MARK 15 is a cost effective, flush mount, battery charge controller with digital system monitoring. The MARK 15 is available for 12 or- 24- volt systems with charging current up to 15 amps, and provides efficient charging while protecting the batteries from damage due to overcharging. This controller is designed for use in mobile or station ary photovoltaic energy systems, with complete system monitoring of battery voltage, solar charging current, and charge set-point calibration. Charge-mode status lights, battery condition LED bar-graph, a blocking diode, battery fuse and array fuse are standard.

SWITCHING SHUNT REGULATION - The MARK 15 will allow maximum array current to flow into the battery through a blocking diode, lighting the "SOLAR CHARGING" light (LED), until the battery voltage reaches the charge termination set-point. At this point, a shunt transistor will turn on, shunting the solar array, turning off the "SOLARCHARGING" LED, lighting the "BATTERY CHARGED" light and halting any further battery charging.

A -Temperature Compensation:
Temperature compensation is generally recommended for sealed batteries or where batteries are expected to experience temperature variations of more than +10-° from 25-°C during periods of charging. A small temperature sensor on a 10 foot lead monitors actual battery temperature and adjusts the charging thresholds according to battery temperature. The rate of compensation is -5mv/-°C per battery cellfrom 25-°C.
| - MONITORING
-· Digital monitoring of:
- a) System battery- voltage
b) Solar charge current
c) Charge set-point calibration
-· "SOLAR CHARGING" light
-· "BATTERY CHARGED" light
-· LED bar-graph BATTERY CONDITION indicator
-· BAR or DOT display
-· Power saver display mode | - | - When the battery voltage drops to the charge resumption set-point, the shunt transistor will turn off and charging will resume. The result is that when battery capacity is low, charging will be continuous. As the battery charges up, current will pass into the battery for shorter and shorter periods, until at full charge, it will pulse current into the battery to achieve and maintain full charge.
| - | - E - Low Voltage Disconnect (LVD) / Generator Start:
The MARK 15 can be provided with an auxiliary relay. This relay can be used to protect the battery from low-voltage damage by disconnecting loads or by signaling a standby generator to start or stop battery charging. The relay is rated for 10 amps. This option provides the common, the normally open and the normally closed voltage-free contacts of the relay.
