The 3000SP will remain in Standby until:
•the difference between the photovoltaic
production and the power required by the load is
less than 100W
•the battery is fully charged and the photovoltaic
production is higher than the consumption (with
tolerance of 100W)
•the battery is flat and the photovoltaic production
is lower than the consumption (with tolerance of
100W)
When the power produced from the photovoltaic
system is greater than the energy required by the
loads, the 3000SP system 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 once
again less than the power required by the loads, the
system will use the energy stored in the battery to
power 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 missing
energy will be taken from the grid.

3.1 Battery connection
3.3 Grid Connections
In case of a single battery, two power cables (positive and negative) and a communication cable will be connected.
This connection is shown in the figures below:
Note: The DIP switch positions must be set according to the factory settings (if
modified accidentally, contact technical support)
CONNECTING THE POWER CABLES:
1) Unscrew the 4 screws (A) with a screwdriver.
2) Remove the cover (B), loosen the cable gland (C),
and then remove the stopper (G).
3) Feed the battery cables (F) through the cable gland,
then connect them to the positive and negative
terminals of the inverter (E).
4) Replace the cover on the inverter and secure it with
the four screws; then tighten the cable glands.
CONNECTING THE COMMUNICATION CABLES:
1) Unscrew the 4 screws (A) with a screwdriver.
2) Remove the cover (B), loosen the cable gland (C),
and then remove the stopper (G).
3) Feed the communication cable (inverter side)
through the cable gland on the left side of the
cover, then insert the connector into the CAN port
on the inverter's communication board.
4) Replace the cover on the inverter and secure it with
the four screws; then tighten the cable glands.
Note: The communication cable is located inside the
kit in the inverter box.

When connecting multiple batteries in parallel, connect the communication cable previously connected to the
inverter's CAN port to the CAN port of one of the batteries. This will be referred to as the MASTER battery.
A communication cable will go from the port 1 link of the MASTER battery to the second battery called SLAVE 1,
entering the port 0 link.
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.
The batteries must be connected in a “loop” as shown in the side
photo, and explained below:
The power cable connected to the inverter’s negative pole must be
connected to the MASTER battery, while the cable connected to
the inverter’s positive pole must be connected to the last “SLAVE

8.3 SINGLE WECO BATTERY
8.2 PYLONTECH BATTERIES IN PARALLEL
Note: The DIP switch positions must be set according to the factory settings (if
modified accidentally, contact technical support)

In case of multiple batteries connected in parallel or when adding new batteries to a system with batteries already
installed and working, make sure that the difference between the voltages of all the batteries is less than 1 Volt.
Each battery must be measured individually, therefore make sure the batteries are not connected to each other.
(If the value is higher than 1 Volt, contact Technical Support)
Note: Turn off the batteries each time the position of the
DIP switches is changed.
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 defining the correct positioning of the DIP Switches:
The MASTER battery must be connected to the communication cable inside the battery box starting from the RS485-B
port and arriving at the RS485-A communication port of the Slave 1 battery. (Attention: do not connect the RS485-A
port to the Master battery).
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 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
terminal.
8.4 WECO BATTERIES IN PARALLEL
In case of a SINGLE BATTERY:
1. Connect the BMS-CAN input
2. Set the DIP switches as shown
in the photo
3. The power connections must
be made by attaching the
appropriate B+ and B-
connectors to the corresponding
input (as shown in the figure).

Correctly position the current sensors (CT):
Note: The direction of the CTpv is independent of the
installation.
•CTpv (measures the photovoltaic production).
Must be positioned on the phase cable coming out from
the photovoltaic inverter (AC side) on the same phase
where the storage was installed.
Unscrew the 4 screws (A) with a screwdriver.
Remove the cover (B), loosen the cable gland (C), and then remove
the stopper (G).
Route the CT cables through the cable glands on the right side of the
cover, connect the positive and negative cables to the counterpart
contained in the inverter kit, then insert the counterpart into the
corresponding ports on the inverter board.
For the extension cable, it is recommended to use a category five 8-pole mains
cable, or a 2x0.5 mm² cable. In the first case, four conductors will be connected to
one pole of the sensor and the other four will be connected to the other pole.
To prevent the conductor wires from breaking, it is recommended to use a cable
with flexible and non-rigid conductors.
•CTa (measures the current exchanged with the grid).
Position the CTa sensor on the phase where the storage system is
installed, at the output of the import/export meter so that all the power
flows entering and leaving the meter can be read.
Replace the cover and secure it with the four screws; then
tighten the cable glands.

14.3 INITIAL SET-UP PROCEDURE OF THE 3000SP - CTpv SETTINGS AND PHOTOVOLTAIC START UP

To carry out the check, it is necessary to:
1) Switch off the photovoltaic system.
2) Lower the switch of the circuit breaker, the 3000SP system will remain on but will go into error due to
no AC power supply
(or in EPS mode, if previously enabled).
4) Power up the 3000SP by flicking the AC switch up.
6) Check that the PV generation value shown on the
screen is equal to zero.
5) Check that the display shows a withdrawn power value equal to the absorbed power value which can be
measured by placing a current clamp under the import/export meter.

Check that the value of the consumption remains constant*
as the power supplied by the battery increases during

8) The power taken from the
grid should decrease by an
amount equal to the power
supplied by the battery.
The photovoltaic system
remains at zero.
9) Once the photovoltaic system has been activated, check that:
The value of consumption remains constant as the photovoltaic
power increases.
Depending on the photovoltaic production, the
system will work according to the
modes described in Chapter 6.
Note: if the four conditions above are not met,
check the positioning of the CTs
7) Once the countdown is over, the batteries will start to
deliver power according to the availability towards the utility,
trying to reset the consumption from the grid.
*Check that the power of the loads in use does not change:
•Heat pump or pump → load variable over time
•Light or Hairdryer → load constant over time
10) Compare the value of the photovoltaic power shown on the storage inverter's display with that indicated
by the photovoltaic inverter, making sure that they are almost equal.
