Operating Stages Of The System - ABB REACT 2 Series Product Manual

O
perating stages of the system
The REACT2 system enables the storage of unused energy and makes
it available during evening hours or times of maximum absorption,
enabling self-consumption to be maximised. The main operating stages
of the system are:
1. The energy from the PV generator is converted
by the inverter (REACT2-UNO) and powers the
utilities in order to maximise self-consumption. The
unused energy produced is stored in the batteries
(REACT2-BATT).
kWh
2. Once the batteries are fully charged the system
powers the utilities and unused energy is fed into
the grid.
During this stage it is possible that the maximum
limit on active power fed into the grid that was set
by the operator may be exceeded; in this case
the REACT2 system can automatically limit the
feeding of active power to the grid.
kWh
3. When the energy supplied by the PV generator
supplies the energy stored in the batteries thus
kWh
4. When the battery is completely discharged,
the system will draw energy from the grid
