Component description
4.1.
Mode of operation
The
blueplanet hy-switch is a complementary component to the blueplanet
hybrid inverter series. It is not functional without the blueplanet hybrid inverter.
The
blueplanet hy-switch serves as a measuring point and all-pole disconnection
point for the local network. It is connected to the three phases, the neutral
conductor and the earth (PE).
The measuring point is required to record and compensate the consumption of the
local installation in connection with the blueplanet hybrid inverter. This includes all
loads installed behind the blueplanet hy-switch. Therefore, the installation location
depends on the structure of the subnetwork to be compensated; in single-family
houses, it is typically located at the grid connection point.
In addition, the measuring point enables no electricity from the batteries connected
to the blueplanet hybrid to be exported to the public grid (flow direction sensor).
The all-pole disconnection point offers the possibility of disconnecting the local
installation from the public power supply. This makes it possible to temporarily set
up a stand-alone grid with the blueplanet hybrid inverter, e.g., if the public power
supply is disrupted. This function must be enabled on the inverter. Activation is
subject to a fee.

Available accessories
External current sensors are offered as accessories. These enable the measurement
of higher powers, as well as a separation of measuring and switching point. The
current sensors are designed with jack plugs, which are connected to the side of
the component.
