3Receipt and site selection
Carefully remove the ATA from its packaging, and carry out a meticulous inspection. We recommend keeping the
original packaging in a secure place, in case you need to send the ATA for maintenance purposes. In case of transport
damage, notify the carrier and dealer immediately.
We recommend paying attention to the below points in order to choose a correct placement for your ATA:
The electrical installation has to be done by qualified personnel.
ATTENTION: be careful to place the ATA on a surface that is able to withstand the
mechanical characteristics (size and weight) specified in the chapter "Technical
Specifications".
ATTENTION: be careful in using a fixing system suitable to the mounting surface and to
the weight of ATA.
TECNOWARE declines any responsibility if these warnings are disregarded.
1. The ATA is designed to operate in a protected environment. We therefore recommend installing it in a place
with very little or no humidity, dust or smoke.
2. When the ATA is brought from a cold place to a warmer place, humidity in the air may cause condensation in
the ATA. In this case, allow ATA to stand for two hours in the warmer place before beginning with the
installation.
3. In all circumstances, see the “Technical Characteristics”chapter for environmental specifications and check
that the selected area meets these criteria.
4. During normal operation the ATA discharges a minimal amount of heat. So it is necessary to leave at least 20
cm of unobstructed space on the side and 50 cm up and down of ATA in order to keep it properly ventilated.

ENGLISH
ATA Energy Storage System MM 5User’s manual
5. Fix ATA on the choice surface, through the use of screws and dowels. See the image below for the fixing point
on the ATA.
6. Do not obstruct ventilation holes.
7. Do not insert objects or pour liquids in the ventilation holes.
8. Do not rest any object on top of the ATA.
9. Do not keep liquids, flammable gases or corrosive substances near the unit.
4Operating
The typical mode of operation is the SBU mode: the acronym SBU indicates the order of priority of the power supply
used by ATA. The first source is S = SOLAR, i.e. solar panels; the second source is B = BATTERY, i.e. batteries; the third
source is U = UTILITY, i.e. the AC Utility Line.
4.1 Functioning with active PV panels
The equipment is powered by the ATA system by using the energy from the PhotoVoltaic (PV) panels. During this
phase, the ATA simultaneously charges the batteries and works independently without any need to use the mains. ATA
is equipped with a MMPT system (Maximum Power Point Tracker) that allows to find the best workable point to
maximize the power of solar panels, depending to the solar irradiation that they are exposed.

ENGLISH
User’s manual 6ATA Energy Storage System MM
4.2 Functioning with inactive PV panels
The equipment is powered by the ATA system by using the energy stored in the batteries until the photovoltaic panels
are once again active. The stored energy can be used up to a minimum threshold of 30/40% (settable in settings).
Only in the case of this energy not being sufficient will the equipment be powered automatically from the mains.
Should a blackout occur during this phase, the ATA uses the 30/40% of energy remaining in the batteries (UPS function)
to power the equipment.
Once the residual energy has been used up, the system turns off. When the mains or the photovoltaic panels are
reactivated, the ATA Energy Storage System automatically starts up again.
When the battery charger level reaches the threshold value set, ATA Energy Storage System automatically switches to
active panels mode (see section 4.1).

ENGLISH
ATA Energy Storage System MM 7User’s manual
5Other Operating Modes
5.1 Only with PV panels
ATA system use the PhotoVoltaic (PV) Panels energy to power the equipment; simultaneously charges the batteries. In
the case the photovoltaic panels energy is not sufficient ATA use the batteries energy.
To active this modality you need to set correctly the parameters 01 and 16 in the ATA settings. See the chapter
“Settings”.
5.2 Only with the main (UPS)
ATA system use the mains to power the equipment; simultaneously charges the batteries. In the case the mains is not
available ATA use the batteries energy.
To active this modality you need to set correctly the parameters 01 and 16 in the ATA settings. See the chapter
“Settings”.

7Electrical Installation
The electrical installation has to be done by qualified personnel. Follow all the Safety
Standards (CEI Standards in Italy or IEEE elsewhere) for the Input/Output connections
and for the right selection of Input/Output cables.
For safety we recommend using external circuit breaker between AC Mains line and
ATA Input line: the circuit breaker should be qualified as RCCB (Residual Current
Circuit Breaker RCCB) with leakage current protective function (leakage current < 300
mA).
For safety we recommend using external circuit breakers between ATA Output line
and the loads: the circuit breakers should be qualified as RCCB (Residual Current
Circuit Breaker RCCB) with leakage current protective function (leakage current < 30
mA).
It is also advisable to install a PV protection system between the PV panels line and the
PV panels Input of ATA, dimensioned according to the installed PV panels.
ATTENTION: for safety and efficiency it is recommended to use always cables with the
cross section equal or thicker than the specified one into the following table.
TECNOWARE declines any responsibility if these warnings are disregarded.
The ATA models have inside the case only the electronic parts: the batteries are installed externally.
Before starting the installation procedure, be sure that:
1. The AC Utility Line for the ATA has been removed, the PhotoVoltaic (PV) panels
and the batteries pack are disabled.
2. The ATA is completely OFF (only if graphic LCD panel is OFF).
Is necessary to apply a label, as the following one, into the AC input and output
distribution box.
