Make sure that the solar
panels are exposed to
sufficient sunlight. Check if
the solar panel array is sized
correctly in terms of power.
When the charger is too hot,
the charge current will be
reduced automatically.
Please check the charger's
mounting location and make
sure of sufficient cooling.
If you wish to fully charge
the battery, please reduce
the DC loads connected to
the battery.
Check if the Charge Voltage
(bulk/absorption) is not set
too low for the used
battery.
Install larger DC cables. See
the DC cable size table in
chapter 2.3 of the
installation manual.
Make sure that the solar
panels are exposed to
sufficient sunlight. Check if
the solar panel array is sized
correctly in terms of power.
Check if the Nominal Battery
Voltage corresponds to the
actual used battery.
Please if all battery charge
voltages are set correctly
(Charge Voltage as well as
Float voltage if applicable)
Please check if the
connected battery is
suitable for the equalization
stage. In general, only
Flooded (open lead)
batteries are allowed to be
equalized periodically.
Replace battery
Please check if at least one
LED is lit on the charger
