Windy Nation TrakMax 40 MPPT Solar Charge Controller - Manual (Page 17)

TrakMax 40 User Manual
Revision 1.0
A solid green LED indicates the charging source is functioning properly. A flashing green LED indicates an
error condition exists. The multi-color LED indicates the particular operating mode and the battery capacity
level.
5.1 C HARGE C ONTROL
Battery Capacity: <LVD <LVR, >LVD >LVR
LED Indication: Red Orange Green

If the single color LED or multi-color LED flashes, it indicates an error condition such as over temperature,
over current, low voltage disconnect, reverse connection for solar modules, and over voltage of load. The
green LED’s flash time depends on the condition or function they are displaying; See table 5.2.
