3 Description of the device
3.1 Mode of operation
The device ensures the supply of the consumers in the household from three different sources: photovoltaics, energy
storage unit and the public power grid. If there is sufficient solar radiation on the photovoltaic system and thus a certain
minimum voltage is applied to the device, the start process begins. The feed-in process begins once the PV generator has
passed the insulation test and the grid parameters are within the requirements imposed by the grid operator for a
specific monitoring time. The inverter remains in operation as long as it is supplied from the photovoltaic system or
battery storage unit. If the supply voltage is too low, it shuts down until the voltage of the photovoltaic system reaches
the minimum value again.
The power of the photovoltaic system is used to supply consumers and charge the energy storage unit. This means that
the energy generated can be used to supply loads with a time delay. If sufficient power cannot be provided by the
photovoltaic system and the energy storage unit, the missing energy is taken from the public grid.
In the event of a utility grid failure, the device can establish a backup power supply as long as it is supplied from the
photovoltaic system and the battery storage. This function requires the KACO blueplanet hy-switch as a grid
disconnection point.
It is possible to use both integrated energy management and suitable external energy management. The selection is
made in the blueplanet hy-sys software belonging to the device.
3.2

Integrated energy management

The device has integrated energy management. It is designed for mains parallel operation with load compensation. To
use load compensation, the KACO blueplanet hy-switch is required as measuring point. The settings for integrated energy
management are made in the blueplanet hy-sys software.
3.2.1

Operation mode: Self-consumption optimisation with load compensation (Self-Consumption)

If the photovoltaic system supplies energy, priority is given to connected loads. If the photovoltaic system has a surplus of
energy, the energy storage unit is charged with it. When the energy storage unit is fully charged and there is still a surplus
of energy, this energy is fed into the public grid. If the charging capacity of the energy storage unit has a limiting effect, it
can be fed into the public power grid in parallel with the storage unit charging. The feed-in power into the public power
grid can be limited to a freely selectable maximum power during installation. If the power of the photovoltaic system is
not sufficient to supply the load, the energy storage unit is discharged to fully supply the load. If the discharge capacity of
the energy storage unit is not sufficient, energy is taken from the public power grid.
3.2.2

Operation mode: Battery Charging

Priority battery charging is used to maximise the charge level of the energy storage unit. If the photovoltaic system
supplies energy, priority is given to connected loads, provided this is possible by the hardware for load compensation.
The excess energy is used to charge the energy storage unit with the maximum possible power. If there is an energy
surplus, this energy is fed into the public grid. The maximum photovoltaic feed-in power into the public grid can be set by
the installer.
3.2.3

Operation mode: External presetting (External)

In this operating mode, the hybrid inverter is controlled by an external energy management system. In this case,
compliance with the relevant standards must be ensured by the system operating company.
