1. OPERATION OF LEONARDO PRO X
1-
The Leonardo PRO X is designed to store energy from existing photovoltaic
plants, connected to the ON-GRID mains (
AC configuration
) or, in configuration
with Western CO. charge regulators, it allows new photovoltaic plants to be set
up with lithium battery storage
(
DC configuration
). The system can be
integrated by Leonardo PRO X Slave which allows to increase the available
power, or the management of three-phase systems.
2-
The Leonardo PRO X, in
AC configuration
, draws energy from the AC input
by storing it in a battery and trying to cancel or minimise the power fed into the
grid. The power available for the loads is the sum of the power of the existing
PV system, the power of the Leonardo PRO X inverter and possibly the power
available from the exchange meter.
In
DC configuration
, on the other hand, the batteries are charged thanks to the
charge regulators and in this case the available power output is equal to that of
the Leonardo PRO X plus the power available from the exchange meter, if
applicable.
3-
If the consumption of the house exceeds the power of the inverter, the
Leonardo PRO X implements the
PEAK SHAVING
function, i.e. the converter
delivers the power required by the loads with the support of the mains;
4-
If the battery is fully charged, the management system can no longer
absorb the energy directly produced by the PV plant. The excess energy will be
directly fed into the grid, in
FEED-IN
mode. For photovoltaic plants in DC
configuration, it is possible to deactivate the grid feed-in
(
ZERO FEED-IN
) and a
potential-free contact is available for
maximum self-consumption
to activate domestic loads (water heater,
heat pump, etc.), increasing its share of self-consumed energy;
5-
At night or when there is no power production from the PV system, the converter uses the energy stored in
the battery with the support of the mains if the demand exceeds the capacity of the device;
6-
In case of
BLACK-OUT
, the privileged utilities connected on the EPS line are powered until the battery runs
out by creating an isolated
OFF-GRID
network. In case of DC configuration, it will be possible to continue to
draw energy from the photovoltaic plant.
