Resumen
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 power supplies, which includes an AGM battery (BP84 84 Ah 12 V Sealed Rechargeable Battery) and a large solar panel (SP370-L 370 W Solar Panel). As an additional benefit, Campbell Scientific provides full support of the SunSaver MPPT.

Descripción detallada
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 8.5 V and the LVR to 10.0 V. Caution: Draining a battery below 11.5 V will shorten the life of the battery.
