概览

The 38898 consists of a Morningstar 15 A charge regulator that has been re-configured by Campbell Scientific and includes the mounting hardware to mount it to a 2.54 cm (1 in.) grid back panel. This charge controller is well suited for large solar panels, such as the SP305-L 305 W Solar Panel. As an additional benefit, Campbell Scientific provides full support of the SunSaver MPPT.

优势与特点

  • 12 V or 24 V battery charging
  • 60 Vdc maximum input compared with the 50 Vdc on the CH201 and 40 Vdc on the CH150
  • Selectable battery type: gel, sealed, AGM, flooded
  • Programmable low voltage disconnect (LVD)
  • Auto-equalize feature for flooded battery only
  • Terminals for remote temperature sensor (RTS) to compensate charging based on battery temperature; use pn 38899
  • Built-in temperature sensor for use when no RTS is provided
  • Battery status LEDs to provide battery state of charge and indicate fault condition
  • RS-232 communication with pn 34540

技术说明

The 38898 uses maximum power point tracking. While the 38898 is capable of RS-232, Modbus, and USB communications, only RS-232 communication is supported through the hardware. Note: When reading parameters off the 38898 using a data logger, you must use the CPI/RS-232 port. This functionality does not work when using the control ports.

The 38898 offers the ability to select the battery type: gel, sealed, AGM, or flooded. To set the battery type, use a jumper and switch #1.

The 38898 offers programmable low voltage disconnect (LVD). From the manufacturer, the 38898 comes with an 11 V LVD when switch #2 is on and an 11.5 V LVD when switch #2 is off. At Campbell Scientific, we prioritize data over battery health and reconfigure the LVD to 6 Vdc when switch #2 is on, and we ship the 38898 with switch #2 on. When switch #2 is off, an LVD of 11.5 Vdc is used. Caution: Draining a battery below 11.5 V will shorten the life of the battery.
