Solar charging
Only applicable if a solar panel (max 600 Watt) is connected to the ' solar
input'.
If the charging converter is switched off because the D+ ( ignition ) is absent,
the battery will be charged via the internal solar charge controller. The
maximum charging current via solar is equal to the set charging current (max.
40Amp). A connection between the solar symbol and battery appears at the
bottom of the display as an indication that the charging process is in progress.
The corresponding values can also be read. See chapter 'display'.
Charging process
The charging process consists of 3 phases: bulk, absorption and float
charging. In the main charge stage (bulk), the converter delivers its maximum
(available) charging current. The battery will become fuller and the output
voltage will increase until the set charging voltage is reached. After this, the
converter switches to absorption. The set charging voltage remains constant
and the charging current will decrease as the battery becomes full. When the
minimum current limit is reached, the converter will switch to float charging.
The battery is full and is maintained with the set floating charge voltage. The
charging phase the converter is in can be read in the display. See chapter
'display'. When changing between charging converter and solar, a new
charging process will be started.
Charging LiFePO4 batteries
Prevent the LiFePO4 battery from shutting down due to intervention by the
BMS. If necessary, install a battery protector (SBP series). If the LiFePO4
battery has shut down, the BMS will first have to be reactivated.

All relevant information regarding the charging process is shown on the display.
By briefly pressing the 'Mode' button, the background lighting of the display
switches on briefly (1min).
The display on the display can be scrolled through with the and buttons.
In this way, the various charge values can be called up.
Last called info remains displayed.
