11 Operation

The device is operating automatically without any user interactions required.
Operation with engine running
During the trip, when the alternator is operating, the device establishes a direct power supply line between the in-
verter and the starting battery. This allows the use of the air conditioner of the living side, the coffee machine and all
the other appliances without stressing the vehicle charging system. This also keeps the batteries safe from deep dis-
charges. When the engine is idling, or the vehicle accessories are operating, the voltage supplied by the alternator
drops and the device activates the economy mode. In this mode the compressor of the air conditioner is switched off
via a relay on the control connector. When the power supply from the alternator is restored, the device reactivates
the compressor. If even in this condition the alternator fails to meet all energy requirements, the power supply from
the house battery is directed to the inverter. When the alternator voltage returns back to optimal voltage range, the
power supply is switched back to the starting battery and the air conditioning compressor is reactivated, turning off
the economy function.
