INTERNAL SCHEME
Pic.3 Internal Scheme
1.
Isolated bidirectional inverter
: it is the AC / DC conversion system and it charges and discharges the battery in accordance
with the management profile, receives the charge and discharge power set-point from the energy manager, the nominal
power in discharge it is 2.4kW the nominal power in charge is 2.1kW;
2.
Input
Relè
: it takes care of connecting the inverter in parallel with the On-Grid grid, it is responsible for disconnecting the
grid in the event of out-of-specification parameters (voltage and frequency);
3.
Battery:
it is the 48V electrochemical storage system with its management profile. Leonardo PRO X 3000/48 Li has a
communication cable with CAN BUS, with a direct RJ10 type connection, to the internal LG CHEM battery management
system;
4.
Energy Manager
: determines the set-point for charging and discharging power based on the production of the existing PV
system and the consumption of the domestic system;
5.
P1 control meter:
it is a direct insertion meter, which can be installed in any switchboard or switchboard with an impulsive
communication interface;
6.
Datalogger:
it is the integrated data acquisition system for remote monitoring and setting, it is connected to Internet;
7.
Existing PV inverter
: it is the inverter dedicated to photovoltaics for the production of incentivized energy, it is declared to
the GSE in the incentive practice;
8.
Existing PV system
: this is the existing photovoltaic field, it is declared to the GSE in the incentive procedure.
9.
Output switch
: in case of blackout it switches the privileged loads to the EPS output of the inverter in order to guarantee
their power supply without perceptible discontinuity.
10.
TA current sensor
: measures the current on the AC-IN line to be supplied to the energy manager for energy management
