Model:: 38898
Item Number:: 38898
Warranty:: 5 years
Compliance:: The 38898 regulator is re-programmed at Campbell Scientific to have a 6 Vdc low voltage disconnect (LVD) to protect the data instead of the battery. It can be programmed using pn 34540 and MorningStar MSView software.

Overview

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 370 W Solar Panel). As an additional benefit, Campbell Scientific provides full support of the SunSaver MPPT.

Key Advantages

A Charge Controller Designed for Large Solar Panels

Technical Description

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.

Benefits
