In the fulk stage,
the charging
converter (battery
DC input) does not
deliver its full
charging current
In the bulk stage,
the charge
controller (Solar
input) does not
deliver its full
charge current
Charging process
is completed, but
the battery is not
full
A battery is
connected to the
input or output,
but the charging
converter does not
detect it.
Battery no longer absorbs
current.
Charger converter is very
hot. Charging current
reduced.
Alternator cannot supply
enough current.
Solar panels produce too
little energy to provide the
full charging current.
Battery sulphated.
No/poor contact between
battery and converter.
With LiFePO4 battery:
the BMS has disconnected
the battery
Internal fuse defective
Battery is almost full.
Battery sulphated.
Charging current is
restored when internal
temperature has dropped
sufficiently.
Other large consumers are
on and/or the alternator is
too light for the
application.
The charge controller
depends on the panel yield.
This will always fluctuate.
Check the battery.
Check all connections and
fuses.
Activate the BMS by
external charger.
Return the converter to
your supplier or
manufacturer.
