The 3000SP 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)
When the power produced from the photovoltaic
system is greater than the energy required by the
loads, the 3000SP 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 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
Note: To connect multiple batteries in parallel, use the appropriate cables (power and
connection) contained in the kit.
Note: The DIP switch positions must be set according to the
factory settings
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.
Note: The communication cables are located inside the
kit in the WeCo battery box
Note: Maximum DoD programmable 90%

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 1.5 Volt.
Each battery must be measured individually, therefore make sure the batteries are not connected to each other.
(If the value is higher than 1.5 Volt, contact Technical Support)
Note: Turn off the batteries each time the position of the
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 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. (NOTE: 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.

•High power loads (such as ovens, washing machines, heat pumps) may not be supported by
the inverter in EPS mode, given the maximum power that can be delivered under these
conditions.
•Loads with high inrush currents (such as pumps, compressors or in general devices driven by
electric motors) may not be supported by the inverter in EPS mode, as the inrush current, even
if only for a very short period, is considerably higher than that supplied by the inverter.
•Inductive loads (such as induction plates) may not be supported by the inverter in EPS mode,
due to the waveform of these devices.
Identify the critical or priority domestic loads: it is advisable to identify the domestic loads strictly necessary
during power outages, such as lights, refrigerators or freezers, emergency sockets.
Connect the phase, neutral and ground wires to the LOAD output located on the right side of the bottom of the
inverter.
NOTE: the LOAD output must only be used for connecting the critical load.
The procedure for connecting the power cables to the LOAD output is the same as that for connecting the cables to
the GRID output:

19.2. EPS MODE (OFF GRID) - ACCESSORIES REQUIRED
19.1 EPS MODE (OFF GRID)

CHANGE-OVER SWITCH
In case of maintenance of the components of the photovoltaic system or in case of an inverter that cannot be used,
it is recommended to install a change-over switch so that the loads normally connected to the inverter's load line
can be fed directly from the grid.
DOUBLE SWITCH CONTACTOR
For subsidised systems, a double switch contactor can be installed. This device will ensure that the critical loads
are normally powered by the grid, they will be powered by the EPS LOAD line of the inverter only in the event of a
power failure thanks to the change-over of the contactors
230V
230V
If the alternating voltage supplied by the grid is present (normal operating condition), both the standard loads of
the system and the priority or critical loads are supplied by the grid without the need to use a double switch-over
contactor. This operation is shown in the figure below.
It should also be
noted that the
LOAD output is
always energised,
even when the
mains voltage is
present.
Position 1→ Priority loads connected and
powered by the inverter's LOAD line

•System with one or more WECO batteries: 13 A (3,000 W)
In the event of a blackout, the alternating voltage supplied by the grid will be lost; this condition will cause
the internal contacts of the hybrid inverter to switch over which, once the set activation time has expired, will
continue to supply an alternating voltage of 230V to the LOAD output, supplying power only to the critical
loads according to the availability of the batteries and PV system.
