PB
. Understanding the Various Operational Modes
The FLEXmax 80 modes of operation will change occasionally during the day based on the PV array
output and the battery system state of charge. The FLEXmax 80 operating modes are displayed at the
bottom right hand corner of the STATUS screen.
Absorbing
The FLEXmax 80 is in the Absorb (constant voltage) charge stage, regulating the battery
voltage at the Absorb voltage set point (modified by battery temperature compensation if installed).
During this cycle, the
ChgT
counter in the Misc menu is counting up towards the user defined
Absorb
Time Limit
. If the system cannot regulate the battery voltage at the
Absorb
voltage set point, then
the FLEXmax 80 reverts back to the
Bulk
charge stage, display
MPPT Bulk,
and the
ChgT
counter may
start counting down towards zero minutes or until the
Absorb
target is met. See page 48 for more
information.
AutoStart (Auto Re-Start)
Mode 1—Once every 1.5 hours in Bulk cycle and in Mode 2, once every
1.5 hours in the
Bulk, Absorb
and
Float
recharging modes, the FLEXmax 80 will start over from sleeping
and re-track (full track) and re-calibrate the current sensor. Mode 0 is disabled completely. (See
Stats
menu). Note: If enabled,
AutoStart
also occurs during the
MPPT EQ
cycle.
BatTmpErr
The battery temperature sensor is shorted or damaged. The charging voltage will not be
temperature compensated and the cooling fan will continuously operate.
BatTooHot
The battery temperature sensor has detected a battery temperature of over 50°C. The
FLEXmax 80 will stop charging the battery and wait for the battery to cool below 50°C.
Charged
There is an external DC source other than solar keeping the battery above the
Float
voltage
set point-- the FLEXmax 80 will stop charging. The display may also appear when the charge cycle is
transitioning from
Absorbing
(upper target voltage) to
Floating
(lower target voltage).
EQ 0:00
This is the time elapsed in hours and minutes since the
Equalization
voltage set point was met.
If the
EQ
voltage set point is not maintained, the controller will revert back – the EQ timer will pause
until the batteries are regulated at the
EQ
voltage set point again. The paused time can be viewed in
the
Stats
menu.
EQ Done
Once the set
EQ
time (between 1 and 7 hours) has successfully completed,
EQ Done
will be
displayed either until a button is pressed, or the next morning’s wakeup. The FLEXmax 80 will transition
to
Float
cycle at the end of the completed
EQ
cycle.
EX-Absorb
There is an external DC source other than solar keeping the battery above the
Absorb
voltage set point. The FLEXmax 80 will stop charging.
Floating
The FLEXmax 80 is in the Float (constant voltage) charge stage and is regulating the battery
at the
Float
voltage set point (modified by battery temperature compensation, if installed). If the
system cannot maintain the
Float
voltage set point, (e.g. AC and/or DC loads are on), the FLEXmax 80
will employ the
MPPT
function, display
MPPT Float
, and try its best to regulate the batteries to the
Float
voltage set point.
