PB
Sleeping
The PV voltage is two volts less than the battery voltage. This may also appear during the day
when the FLEXmax 80 is transitioning between certain states, or due to other conditions.
SysError
(Very rare) System Error indicates an internal non-volatile memory error. The unit will stop
operating when this message is displayed. Call the factory if you see this message (360-435-6030).
Tracking
In
Auto-Sweep MPPT
mode, the FLEXmax 80 is doing an initial tracking of the panel voltage from
VOC towards battery voltage after wakeup. This display also appears when the controller transitions from a
target set point (
Absorbing/ Floating/EQ 0:00
) to the MPPT state (
MPPT Bulk/ MPPT Float/ MPPT EQ
).
Unloaded
The battery terminals abruptly unload.
Unloaded
is also displayed if the battery breaker trips
while MPPTing or the battery voltage is set too low.
Wakeup
As the PV open circuit voltage (VOC) rises above the battery system voltage by two volts, the
FLEXmax 80 prepares to deliver power to the batteries. During this period, the FLEXmax 80 is calculating the
pulse width modulation (PWM) duty cycles, turning on power supply voltages in the proper sequences, and
making internal calibrations. At wakeup, the FLEXmax 80 closes its relays and then starts tracking the input
voltage (the “initial” tracking) towards the battery voltage. At dawn and dusk this may happen many times
until there is (or is not) enough power from the PV array to keep going. Wakeup is also a time when the
FLEXmax 80 acquires a new VOC.
Zzzzz...
At night (after 3 hours of continuous Sleeping) the FLEXmax 80 will display
Zzzzz...
until the
next wakeup. At the next wakeup, (usually the next morning), the daily statistics of a single FLEXmax 80,
(AmpHours, KWh, etc.), will accumulate into the total statistics and then the displayed daily statistics and
End of Day
summary will clear. A
Bulk
charge will automatically initiate at the next Wakeup. A FLEXmax 80
combined with a HUB and a MATE will log at midnight.
