The Inverter will remain in Standby until:
•the difference between the PV production and the
power required by the loads is less than 100W
•the battery is fully charged and the PV production
is higher than the consumption (with tolerance of
100W)
•the battery is flat and the PV production is lower
than the consumption (with tolerance of 100W)

6. OPERATING STATES IN SELF USE
5. QUICK INFO ON SYSTEM STATUS
When the power produced from the photovoltaic
system is greater than the power required by the
loads, the Inverter inverter will charge the battery
with the excess energy.
When the battery is fully charged, or when the
charging power is limited (to preserve the integrity of
the battery), the excess energy will be exported to
the grid.
Charge
When the power of the photovoltaic system is less
than the power required by the loads, the system will
use the energy stored in the battery to supply the
domestic utilities.
Discharge
When the sum of the power produced by the
photovoltaic system and supplied by the battery is
less than that required by the loads, the extra
energy will be taken from the grid.

3.1 Connessione Batteria
If the system has to be switched off, make sure to disconnect the AC voltage first by
opening the dedicated switch.
NEVER turn off the batteries before disconnecting the AC voltage, therefore with the

In case of a single battery, two power cables (positive and negative) and a communication cable shall be connected.
This connection is shown in the figures below:
Note: The communication cable is located inside the
kit in the inverter box.
Note: The DIP switch positions must be set according to the
factory settings
The communication
cable shall be
connected to the
battery's CAN port

When connecting multiple batteries in parallel, connect the communication cable between the inverter's CAN port
and the CAN port of one of the batteries. This battery will be referred to as the MASTER.
A communication cable will go from the link port 1 of the MASTER battery to the Link port 0 of the second battery
called SLAVE 1.
In case of additional batteries, the communication cable will be connected as indicated above for the connection of
the MASTER battery to SLAVE 1.
The last battery will only
have the port 0 link connected.

DIP switches changes.
To access the battery connection, remove the cover by unscrewing the crosshead screws.
In the event of MULTIPLE BATTERIES, connect the communication cable from the CAN port of the inverter to the
CAN-BMS port of the MASTER battery after correctly setting the DIP Switches:
The RS485-B port of the MASTER battery must be connected to the RS485-A port of the Slave 1 battery using the
cable provided inside the battery box . (NOTE: the RS485-A port of the Master battery will remain not connected).
In case of additional batteries, the communication cable will be connected between the RS485-B port of the previus
battery to the RS485-A port of the following battery.
The last battery will only have the RS485-A port connected.
As for the power connections, all the batteries must be connected in parallel using the power cables supplied,
making sure that the cable does not exceed a length of 2.5 m.
The “NEGATIVE” power cable coming out from the inverter must be connected to the MASTER battery on the
NEGATIVE terminal, while the “POSITIVE” cable must be connected to the last SLAVE N battery on the POSITIVE
