Equalisation charging phase
(only for AGM and liquid electrolyte battery type)
The equalisation charging phase serves to compensate the
cell voltages and can reduce any sulphation.
If the voltage of the battery drops below 11.1 V, it is assumed
that the battery has deep-discharged. The device is switched
to the equalisation charging phase for two hours. At the end
of this period, it changes automatically to the float phase.
– Deep-discharged batteries can be permanently
damaged. Equalisation charging cannot repair
this.
– Liquid electrolyte batteries can create explosive
gases, so ensure there is adequate ventilation.
Check the liquid level at regular intervals. Over-
charging can damage your battery; check the
technical data for your battery.
– Equalisation charging increases the charging volt-
age; this may damage the consumer. Ensure that
all consumers are designed for these voltages.
Parallel mode
If load current is consumed whilst the battery is being
charged, it is served from the available solar charging current.
If the consumed current exceeds the available solar charg-
ing current, the device cannot charge the battery. The device
starts charging automatically once an adequate amount of
solar charging current is available again.

Operation
The display H6 shows different system settings. Press the
key (T) to switch between LED H3, H4 and H5 and display this
in H6. If the key is pressed again, the system starts at LED H3
again.
Battery type
The battery type can only be set for battery 1, battery 2 is as-
sumed to be the same battery type.
Query
– Press (T) until LED H3 illuminates;
the saved value is shown in display H6.

Change
– Press key (T) for 5 seconds until the display H6 flashes.
– Press the key (T) to set the required value.
– If the key is not pressed for 5 seconds, the displayed value
will be saved and flashing stops.
