Technical description

If a mains voltage and voltage generated by the inverter (RV house battery) are both connected to
the device, the use of the mains voltage has priority (fig. 1, page 3). If only voltage generated by
the inverter is available, the power supply from the battery is used (fig. 2, page 4). This ensures
that the limited power of the battery is only used when necessary.
