1. Introduction
The 3000SP storage inverter is an AC-connected bidirectional electrical energy inverter developed for
photovoltaic production systems and domestic storage systems. The inverter can be combined with lithium
and lead batteries of different capacities. The system is also compatible with all existing photovoltaic
inverters and modules and can be integrated into an existing system or installed together with a new
photovoltaic system. The 3000SP storage inverter is able to operate even when disconnected from the grid,
i.e. in the event of a power failure.
The product is equipped with an LCD display and keypad, simple and user-friendly interface that records
data on the energy produced and any errors for quick and easy assistance and support.
The 3000SP storage system is the best solution to optimise the use of energy produced by renewable
sources. The system is able to manage the bidirectional flow of electricity, while controlling the power
produced by the photovoltaic modules, the power stored and taken from the battery, the power exchanged
with the electrical grid and the power supplied to utilities.
The inverter can operate in different ways: automatic, forced charging from the grid and the possibility to
charge / discharge the battery according to the customers’ needs. In automatic mode, the 3000SP inverter is
able to independently optimise the use of the renewable energy and batteries, minimising the purchase of
electricity from the national grid. The second mode forces the energy to be drawn from the grid to charge
the battery, when needed. The third option allows programming the battery discharge hours and modes,
giving the customer complete flexibility.

4. Electrical connections
•Carefully assess the risks deriving from electric shocks and chemical hazards!
•Use a multi-metre to check the DC polarity of the battery and cables before connecting the power supply
between the batteries and inverter.
NOTE: an inverted polarity connection may cause irreparable damage to the inverter and batteries.
•In order to enable safe connection and disconnection of the inverter during installation and maintenance,
a 100A DC disconnecting device must be installed between the 3000SP inverter and battery. This
operation is not necessary if lithium batteries with BMS are used as they have an internal disconnecting
system, such as Pylontech US2000B and US2000PLUS batteries supplied with the Azzurro ZCS storage
inverter.
Note: the Pylontech US2000B and US2000PLUS batteries, as well as the Tawaki Maui 4 kWh and Weco
HeSU 4K4 batteries do not require a disconnecting device for connecting to the storage inverter. The
Cable kit, which includes crimped power cables for connecting the Pylontech batteries to the 3000SP
storage inverter, is supplied separately. It is recommended to ensure that your storage kit is equipped
with this accessory. In the case of Tawaki and Weco batteries, the connection kit is already inside the
package.
•A 25 AC disconnecting device (circuit breaker) must be installed between the 3000SP inverter and the
power grid. It is also recommended to use a differential with a trip threshold of 30 mA between the
3000SP inverter and power grid.
•For safety and proper functioning of the system, it is important to use a cable of the appropriate type and

1) Correctly position the two current sensors (CT):
-the CTa for measuring the energy exchanged with the grid must be positioned at the output of the
exchange meter (utility side) and must include all the phase cables entering or leaving the meter.
The CTa will therefore measure the energy taken from and fed into the grid by the photovoltaic
system.
-The CTpv for measuring the photovoltaic production must be positioned on the phase cable exiting
the photovoltaic inverter (utility side) or from the production counter, and will only measure the
energy generated by the photovoltaic inverter.
2) Extend the cable of the two sensors with a category 5 network cable (8 pole) using the caps supplied.
The cable can be extended by up to 100 metres with a minimum loss of signal
