Operation
English
Many options will be installed prior to the
purchase of your new RV, however there are a
few options that you should be aware of while
operating your new power center.
The built-in microprocessor selects the best
mode for your battery automatically and
determines which operating mode is best
suited to recharge or maintain optimum
battery condition.
CHARGING FLOW CHART
Time (Hrs)
Voltage (V)
DESULPHATION CHARGE - PULSE
CHARGING
If the initial battery voltage is less than 10V,
the charger will start desulphation mode with
pulse charge profile. The pulse charge time
will be 10 minutes.
NOTE:
This charging phase is only available
for Lead Acid Battery.
SOFT START - CONSTANT CURRENT
CHARGING
If at the initial bulk charging, the battery
voltage is less than 11Vdc due to deep
discharge, the charger will go with soft
charge. The bulk charging current is reduced
to half of the maximum current until battery
voltage is higher than 11Vdc or 10 minutes
(whichever is longer) then switches to bulk
charge.
BULK CHARGE - CONSTANT CURRENT
CHARGING
Normally the battery is charged at constant
maximum current until it rises to the bulk
voltage level. The charging voltage changes
with the battery voltage. If the charger cannot
go to absorption mode within 20 hours, the
charger will automatically go to float mode to
prevent over charge of the battery. This is the
safety timer.
ABSORPTION CHARGE - CONSTANT
VOLTAGE CHARGING
When the battery voltage rises to the bulk
voltage level, the charging will switch to
constant voltage charging. Charger will
switch to float stage after 90 or 180 minutes
of absorption charge (90 Minutes for LiFePO4
battery, 180 Minutes for Lead Acid Battery).
FLOAT CHARGE - CONSTANT VOLTAGE
CHARGING
In this stage, the battery is full and only
takes in the amount of current necessary for
maintaining the capacity. The charger will
switch to bulk charge, if the battery current
is higher than 50% of rated current for 5
minutes or the battery voltage is lower than
12.5Vdc for 5 minutes. If the charger remains
at this mode with charging current less than
20% of bulk current for over 60 hours, the
charger will go into the standby mode.
STANDBY MODE - CONSTANT VOLTAGE
CHARGING
In this stage, the charging voltage at this
mode will be 13.2Vdc. This is only for
maintaining the capacity. The charger will
switch to a new cycle after 5 minutes when
the current is higher than 6A.
NEW CYCLE CHARGE EVERY 21 DAYS
Charger will start a new cycle charging of
bulk to absorption to float every 21 days
in either standby or float mode. This new
cycle of charging will refresh the battery
to prevent separation of the electrolyte &
keep the electrode plates in good condition.
The standby auto new cycle charge per 21
days are designed to keep the battery in
good working condition during long period
of resting of the caravan or back up battery
application.
