  • Page 3 R E L A T E D S Y S T E M E Q U I P M E N T The Sunsei CC20000D is an integral part of a solar electric power system that includes a solar panel, a battery and a load.
  • Page 4 • Do not connect the array directly to the battery when the array is connected to the Sunsei CC20000D at the same time. This will cause the fuse to blow when the battery reaches full charge voltage. • Do not wire the Sunsei CC20000D in such a way that it can be connected to an alternator (or other charging source) while the battery is disconnected.

    (See INSTALLATION INSTRUCTIONS 6: WIRE TYPE / SIZE) • Mounting fasteners of appropriate type for wall material • Included are four 3/4 - #6 screws and a spare fuse, 25 amp AGC for the Sunsei CC20000D Also for Flush Mounting: •...
  • Page 6 Sunsei CC20000D: Accepts one wire at 6 AWG (stranded) or two wires at 8 AWG. Large Wires: To connect large wires to the Sunsei CC20000D, use crimp connectors or connect the larger wire to a short, thinner wire using a wire nut (solder these connections).
  • Page 7 14. Sunsei CC20000D MOUNTING Mount the Sunsei CC20000D to the wall or box front using the four screws provided, or other suitable fasteners. Do not remove the four rubber spacers, they provide a gap for added cooling.
  • Page 8 Array Connection: Note the voltage at the panel. Then, immediately note the voltage at the Sunsei CC20000D Array terminals. Ideally, the difference should be no more than ½ volt. If the voltage drop is more, suspect crimp connections that have not been soldered, in-line fuses or fuse holders, or loose terminals.

  • Page 10 M A I N T E N A N C E AVOID DISCONNECTING BATTERY: Do not leave the battery disconnected from the Sunsei CC20000D for an extended period of time (weeks or months). If you need to, then disconnect both battery and array.
  • Page 11 14.0 to 14.2 volts. Systems with very high charge rates (over 20 amps per 100 amp hours of battery) should increase the charging set-point to 14.8 to 15.0 volts. PROCEDURE 1. COMPLETE BATTERY CONNECTION: Connect the battery to the Sunsei CC20000D according to the normal installation instructions.
  • Page 12 M O N I T O R I N G The system operation can be monitored by the meters and the status lights. DIGITAL DISPLAY: The Digital display of the Sunsei CC20000D provides metering of four parameters, selected by a front panel slide switch.
  • Page 13 MONITORING (continued) “BATTERY” CONDITION BAR-GRAPH: This bar-graph provides a general indication of the battery condition. The lights will rise and fall as the battery voltage goes up and down. During the day, the battery voltage can increase and decrease instantly as charging is turned on and off. When the battery is completely charged, the current will begin to pulse into the battery.

  • Page 14: Normal Conditions

    1. “ALWAYS CHARGING” or “NEVER CHARGING” - Depending on your system, it may be normal for the Sunsei CC20000D to go for long periods of constant charging or long periods with no charging. The function of the Sunsei CC20000D is to prevent over-charging of the battery. Therefore, it will charge continuously when the battery voltage is low and stop all charging as long as the battery voltage is high.
  • Page 15 CC20000D can be affected by electrical noise from a converter or inverter. This will not affect the charging function but will cause erratic meter readings. If the Sunsei CC20000D is connected to a bus that is connected to a converter, try connecting the Sunsei CC20000D directly to the battery instead.
  • Page 16 • A bad connection exists to the battery. See BAD CONNECTION: BATTERY (Help Note 9). • A blocking diode or diode isolator exists in the battery connection. If there is a blocking diode, remove it. If there is a diode isolator, modify the system so the Sunsei CC20000D charges only one battery bank.
  • Page 17 TEST: Take an accurate voltage reading at the battery. If this voltage reading stays steady while the reading on the Sunsei CC20000D goes up and down, then suspect a bad battery connection. If the voltage here also moves up and down rapidly, this would indicate either a normal condition or a battery problem.
  • Page 18 Sunsei CC20000D is defective. If possible, perform this step. Disconnect the array(+) connection at the Sunsei CC20000D. With a volt meter, measure the voltage of the array by measuring the array wires where they meet the Sunsei CC20000D.
  • Page 19 • Bad Connection – A bad connection can reduce the charge. See BAD CONNECTION: PANEL and BATTERIES (Help Notes 8 & 9) • Sunsei CC20000D Controller Problem - Perform the FUSE REMOVAL TEST (Page 18) . Also, refer to the Sunsei CC20000D PROBLEM section. Examine the readings from the Sunsei CC20000D meter to see if they indicate a problem.
