Status and Information

LED Indicators

The FLEXmax 100 charge controller has no graphical display. It is equipped with four LED indicators.

IMPORTANT:

The LED indicators do not necessarily tell the amount the controller is actively charging.

The

HARGING

indicator may still indicate Absorption and the

TATUS

indicator may indicate

rising battery voltage, even if another charging source is doing most of the work.

NOTE:

The LED indicators are intended as pointers rather than exact messages. See the next page

for a more specific description of each indicator. Consult the system display for more

information on controller status (see page 35).
