Überblick
Der 38898 besteht aus einem Morningstar 15 A Laderegler, der von Campbell Scientific angepasst wird und an die Gehäuserückwände an der 2.54 cm (1 in.) gelochten Platte angebracht wird . Dieser Laderegler ist gut geeignet für größere Solarzellen wie die SP305-L 305 W Solar Panel. Außerdem bietet Campbell Scientific vollen Support für den SunSaver MPPT.

Technische Beschreibung
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.
