WARNING
When using the internal setup button to change the battery type, please make sure that
the PV array is completely disconnected from the solar charger.
To enter the battery type setup mode using the setup button, it must be pressed for at least 8
seconds. After this 8 seconds the battery type LED starts flashing and the setup button can be
released. Each time the setup button is pressed again, the color of the battery type LED will change
according to the table shown in chapter 3.1. Once the desired battery type color has been reached,
the setup button must be pressed for 8 seconds again to save the new setting. This new setting is
also saved automatically when the setup button has not been touched for more than 15 seconds.
The internal setup button can also be used to reset the solar charger completely to factory default
settings. To do this, the setup button needs to be pressed for at least 20 seconds. A successful
factory reset is confirmed once all three LEDs shortly start to flash in red. Then the setup button can
be released.
3.3 Connecting the PV panels
When the battery connection and setup has been completed, it is time connect the PV panels to the
solar charger (see chapter 2.3 for details). Provided that the PV panel array can supply and maintain
a voltage that is at least 2V higher than the battery voltage, the solar charger will start the starting
process. This process can be monitored by the PV array LED indicator (left side LED) which will now
also be lit.
Please see the table below for various states of the PV array indicator LED:
