The REACT2 system is designed to optimise self-consumption in
residential environments and consists of:
photovoltaic generator (FV) into an alternating current (AC) which can
be fed into the public distribution grid.
In addition, the REACT2-UNO inverter receives data from the ABB
energy meter and performs smart management of energy storage in the
REACT2-BATT battery unit in order to maximise self-consumption for
domestic utilities.
by the built-in Wi-Fi/Ethernet logger which enables the sending of the
system data to a Wi-Fi/Ethernet router which, in turn, sends the data to
the Aurora Vision portal and can be consulted online or through an APP
for smartphones/tablets.
from the photovoltaic generator. The energy stored will subsequently be
used whenever the demand for energy is greater than that produced by
the generator.
It measures the energy at the connection point to
the grid and communicates with REACT2 in order to manage the storage
system.
Based on of domestic consumption and the level of charge of the
batteries it is possible that the maximum limit on active power fed into
the grid, set by the operator, may be exceeded; in this case the REACT2
system can automatically limit the feeding of active power into the grid
(zero injection).
Decisions on how to structure a photovoltaic system depend on a series
of factors and considerations, such as the type of panels, the available
space, the future location of the system, energy production goals over
the long term, etc.
