BATTERY CHARGING
The MiniBoostPRO features a multi-stage charging profile to charge your
house battery. These stages are boost/blending/boost charge and solar/
bypass/ blending bypass. This enables the charge to deliver the maximum
current, until the terminal voltage has risen to the battery’s pre-set level.
Bulk
Bulk is the MiniBoostPRO's primary charging stage where approximately
80% of charging occurs. This enables the charger to deliver the maximum
current, until the terminal voltage has risen to the battery’s pre-set level.
Absorption
Absorption ensures that the MiniBoostPRO's battery’s voltage is kept at its
pre-set level. During this stage, the current is gradually reduced to less than
2A for 2 minutes. This allows the battery to absorb more power.
Float
Float is the final stage of the battery charging profile. This keeps the
MiniBoostPRO's battery at optimum charge, without overcharging or
damaging the battery and allowing the battery to remain continuously
connected to the charger.
The MiniBoostPRO returns from Float to Bulk/Absorption depending on the
modes. This includes if the output current is more than 10A for more than 2
minutes or if the secondary battery voltage is below 13.1V - this normally
applies when a load is detected on the secondary battery.
The charging stage is indicated by the LED flash sequence of the charging
LEDs on the MiniBoostPRO (Table 4).
When charging from auxiliary, the green aux LED illuminates. When charging
from solar, the blue solar LED illuminates. If both the auxiliary and solar
are providing the charging current, both the blue and green LED illuminate
simultaneously. The green auxiliary LED will only flash every 5 seconds, if
the battery is good and no sources are available for charging.
The MiniBoostPRO may get warm while the battery is being charged.
