[. . . ] The green, yellow or red BATTERY CHARGE LED will light depending on the battery charge state. SENSE (+ and -) Battery sense leads are recommended if the controller is located more than 2 or 3 meters from the battery. However, if the sense leads are not connected, the controller will default to BATTERY connections for control. A smaller wire size can be used for sense (draws less than 1 mA current). Note that the wire entry slots into the case for SENSE are smaller than the other system power terminals to prevent mixing the BATTERY and SENSE connections. First confirm that the PV modules are wired for the same voltage as the battery (either 12 or 24 volts). Use caution, since the PV array will generate power whenever in sunlight. Also, be careful not to short-circuit the PV array while connected to the controller, since this will damage the controller. There is a 2 minute delay after connection of the PV array before the controller begins charging. Check that the 8 CHARGING indicator comes on after 2 minutes to confirm that the PV array has been properly connected. 6. If the battery is below the load disconnect voltage, the load will be disconnected (normal LVD). If the load is short-circuited, the controller will instantly disconnect the load and flash the LED's in sequence. It will then be necessary to disconnect the BATTERY + wire and reconnect the battery to reset the ProStar for normal operation (or press the red DISCONNECT button twice if the LCD meter option is supplied). If your battery is a flooded type, use a piece of wire to touch the SELECT PIN to the BATTERY - (negative) terminal or to the negative battery post. This will change the battery charging setpoints from a sealed to a flooded battery. When the change has been made, the green BATTERY TYPE LED will turn off. No damage can occur from touching the pin to other terminals or parts of the controller. Auto reconnect as voltage falls. 10 Automatic Safety Disconnects · Load Short-Circuit: Instant load disconnect. Battery must be disconnected to clear and reset (see section 4. 2-6) · High Temperature: At very high temperatures, PV array first disconnected, then the load. · Emergency: If battery is disconnected, the PV and load are instantly disconnected for safety and to protect the load. Battery charging, equalization, and high voltage functions are corrected for ambient temperature variations. Battery charging is automatically boosted based on low state-of-charge or elapsed time. Temperature Compensation Equalization NOTE: Actual charging setpoints of the ProStar controller are adjusted for temperature, equalizations, and battery type. [. . . ] If the red LED flashes frequently, the most likely cause is a load that is too large for the PV array. Another cause is a defective battery that cannot hold a charge. 14 6. 0 TECHNICAL SPECIFICATIONS MODEL RATINGS ProStar-12 ProStar-20 ProStar-30 PV current (amps) Load current (amps) RELIABILITY 12 8 20 16 30 30 MECHANICAL · All models both 12V and 24V (automatic selection) Note: Current ratings can be exceeded by 25% for up to 5 minutes. 5-year failure rates at a 90% confidence level · ProStar-12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0. 4% ENVIRONMENTAL · Operating temperature . . . . . . . . . . . . . . . . -55 to +100°C · Humidity . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
