Table 1 Battery Voltage and Charge Timer

Battery Voltage ChgT (Charge Timer) Activity/Display

 12.4 V, 24.8 V, 37.2 V, 49.6 V, or 62.0 V,

and less than the Absorbing voltage

No change.

<12.4 V, 24.8 V, 37.2 V, 49.6 V, or 62.0 V

For every minute elapsed, 1 minute is subtracted

from the timer.

<12.0 V, 24.0 V, 36.0 V, 48.0 V, or 60.0 V

For every minute elapsed, 2 minutes is subtracted

from the timer.

< 11.6 V, 23.2 V, 34.8 V, 46.6 V, or 58.0 V

For every minute elapsed, 4 minutes is subtracted

from the timer.

Auto Start (Auto ReStart)

This setting allows the user to choose between continuous MPP tracking or occasional restarts

of the sweeping process. A restart means the controller abandons the existing MPP and

“re-sweeps”, or begins gathering new power point data. See page 55 for more information.

Mode 1: Once every 1.5 hours in the Bulk charging stage

Mode 2: Once every 1.5 hours in the Bulk, Absorbing and Float recharging stages

Mode 0: Auto ReStart is disabled completely. It will continously track the maximum power point

without starting over.

NOTE: If enabled, AutoStart also occurs during the MPPT EQ cycle. See page 25.

BatTmpErr

The battery temperature sensor is shorted or damaged. Charging will not be temperature

compensated. (The cooling fan will continuously operate.) See RTS compensation on page 53.

BatTooHot

The battery temperature sensor has detected a battery temperature of over 50°C. The

FLEXmax will stop charging the battery and wait for the battery to cool below 50°C.

Charged

There is an external DC source other than PV keeping the battery above the Float voltage set

point (see page 29). The FLEXmax will stop charging because it is not needed. The display

may also appear when the cycle is transitioning from Absorbing (upper target voltage) to

Floating (lower voltage).

The charger is in a cycle of equalization. (See page 45.) This is the time elapsed in hours and

minutes since the BATTERY EQUALIZE VOLTS set point was met.

If this set point is not maintained, the controller will revert back to MPPT EQ. (See page 25.)

The EQ timer will pause until the batteries are regulated at the BATTERY EQUALIZE VOLTS

set point again. The paused time can be viewed in End-of-day Summary (see page 20).

EQ Done

Once the set EQ time (between 1 and 7 hours) has successfully completed, the FLEXmax will

transition to Float stage. EQ Done will be displayed either until a button is pressed or the next

morning’s wakeup. The FLEXmax will transition to Float stage at the end of the completed

equalization cycle.
