3 Receipt 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 5 User’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.
4 Operating
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 6 ATA 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 7 User’s manual
5 Other 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

7 Electrical 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.

ATA Energy Storage System MM 15 User’s manual
We advise you to follow the steps below explained:
1. Connect the ATA Input line to the AC mains line (see figure 4). It is mandatory to ground the AC mains line
according to the Safety Standards. Carefully check the grounding of AC mains line. For safety we recommend to
install an external circuit breaker (RCCB type, with leakage current < 300 mA) between AC mains line and ATA
Input line (see figure 4).
2. Connect the line of the PhotoVoltaic panels to the ATA units (see Figure 4). Pay attention to connect the panels
in such a way as to meet the specifications (see the chapter "Technical Specifications").
2.1 Each series of panels shall not exceed the maximum open circuit voltage of 145 Voc.
2.2 The peak power supplied by PhotoVoltaic panels is 3750 Wp.
2.3 Therefore, we assume the use of 250 Wp panels with a rated voltage of 37.7 Vdc, it will be possible to build
a system like the following:
2.3.1 Using PhotoVoltaic panels with a nominal voltage of 37.7 Vdc, it will be able to achieve a serie of panels
(named string) with up to 3 panels because:
3 x 37,7 = 113,1Vdc, that is less than the maximum open circuit voltage of 145 VOC.
2.3.2 Using PhotoVoltaic panels with a power of 250 Wp, it will be able to achieve up to 5 strings of panels
connected in parallel because:
The peak power of each string = 3 x 250 = 750 Wp (number of panels in a string multiplied by the peak
power of each panel).
The peak power of the system = 5 x 750 = 3750 Wp (number of strings multiplied by the peak power of
each string).
2.4 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
3. Connect the devices to be supplied to the ATA outputs. Be sure all the devices have the main switch in OFF
position. For safety we recommend to install an external circuit breaker (RCCB type, with leakage current < 30
mA) between ATA Output line and the loads (see figure 4).
4. Connect ATA to the external Battery Box:
We suggest to use ONLY Battery Box supplied by TECNOWARE. TECNOWARE declines
any responsibilities if this rule is not followed.
Before starting whichever operation be sure that the Battery circuit breaker of Battery
Box is in “OFF” position.
4.1 The ATA unit is designed to operate with a nominal voltage from batteries equal to 48 Vdc (4 x 12Vdc).
4.2 After connecting the battery (follow the instructions of battery box user manual), check the right polarity
and the total voltage of the battery pack.
4.3 Connect the box battery to the ATA, via the cables supplied with the battery box.
ENGLISH
User’s manual 16 ATA Energy Storage System MM
It is compulsory to ground the ATA according to the Safety Standards.
The case of the ATA is internally connected to the ground terminal (GND) of the
IN/OUT terminals, in order to guarantee safety to the user. To guarantee safety it is
necessary to be sure that the local electric plant is supplied with GROUND (in
compliance with the Safety Standards), and that a valid connection is guaranteed
between the GROUND of the UPS and the GROUND of the local electric plant.
Any interruption of the GROUND conductor is absolutely prohibited.
Risk of electric shock at the Output lines if the ATA is ON, even when the ATA is not
connected to AC utility line.
Risk of electric shock at the Output lines while the unit is connected to the AC utility
line.
Risk of electric shock: do not remove the cover. The ATA contains internal parts which
are at a high Voltage and are potentially dangerous, capable of causing injury or death
by electric shock.
There are no internal parts in the ATA which are user serviceable. Any repair or
maintenance work must be performed exclusively by qualified technical personnel
authorized by TECNOWARE. TECNOWARE declines any responsibility if this warning is
disregarded.
Disregard for these warnings may lead to a risk of electric shock to operators.
8 First Start Up
Turning the ATA is very easy. Nevertheless we recommend that, on First Start Up, the following procedure is
observed for greater safety.
1. Be sure the circuit breaker of ATA outputs is in “OFF” position.
2. Place the circuit breaker of external batteries in “ON” position.
3. Place the circuit breakers of PV panels in “ON” position.
4. Place the AC Input line circuit breaker of ATA in “ON” position.
5. As a consequence of point 4, the ATA turns on the graphic display and goes in Stand-by mode: the ATA doesn’t
supply Output power and recharges only the batteries in accordance with SBU mode.
6. Place the On/Off switch of the ATA in “ON” position: the ATA emits a brief acoustic signal and performs a
functioning SELF-TEST. After some seconds the ATA starts to work in SBU mode and the graphic LCD panel will
show the path of energy.
7. Place the circuit breaker of ATA outputs is in “ON” position. Then turn ON the devices (one by one) to be supplied
by ATA, checking the ATA doesn’t report Overload information on the graphic LCD panel and all the devices are
working regularly.

by mode.
Place the AC Input line circuit breaker of ATA in “OFF” position.
Place the circuit breaker of external batteries in “OFF” position.
Place the circuit breakers of PV panels in “OFF” position.
The graphic LCD panel and the leds on the front panel are OFF only when the UPS is
completely OFF.
The ATA can be turned on even in the absence of production from PV panels and in the absence of AC mains.
9.2 Low Battery and Automatic Restart
The ATA reaches the Low Battery condition whenever the batteries reach a charge level allowing the connected
devices to operate for few minutes (about 10% of max charge), following its use without other sources of energy (AC
mains is not available, and the production from PV panels is off).
The UPS warns operators of Low Battery by lighting of the LOW BATT. icon on the graphic LCD.
If the AC mains (or the production from the PV panels) is not restored within a few minutes, the UPS shuts-down
automatically thus preventing the batteries from discharging excessively; the ATA stops supplying Output power,
deactivates control panel indication and goes to a waiting state. Once AC mains (or the production from the PV panels)
is comes back on, the ATA restarts automatically and after some seconds it goes back to work in SBU mode.
The battery charging takes place only when the voltage from the PV panels is present and sufficient.

9.3 Load Testing
The UPS indicates the Output Load level by graphic LCD (as described in the chapter 5).
When the Output load is higher then nominal value the ATA warns of Overload condition by graphic LCD and by
acoustic alarm as described in the “Warning Table” and in the “Troubleshooting” chapter.
The UPS has the capability to accept an Overload less than 110% for 10 minutes.
An Overload between 110% and 150% is accepted for about 10 seconds and after ATA switches automatically to the
Bypass mode.
An Overload between 150% and 200% is accepted for about 5 seconds and after ATA switches automatically to the
Bypass mode..
Once the requested power is back within range, the ATA switches automatically to the SBU mode.
Make sure that the ATA never indicates Overload condition.
Do not connect a load greater than rated value to the ATA (see POWER specifications
in the chapter “Technical Characteristics”), as this may damage the unit. In this case
the warranty is void.
9.4 Operation in Warning Status
During a warning condition the buzzer beeps, it means that there are some problems for ATA operation. Users can get
the Fault code from graphic LCD panel. Please check the “Troubleshooting” chapter for details.
Below you can see the “Warning Table”, with the correspondence between each warning and the relative signals

10 Communication Interfaces
The ATA unit is factory-equipped with RJ45/RS232 and USB Communication Interfaces, usable as communication ports
with a Personal Computer.
Only one of the RS232/USB communications can be activated at one time. To activate RJ45/RS232 communication it
is sufficient to connect the RJ45/RS232 cable only; to activate USB communication it is sufficient to connect the USB
cable only.
The RJ45/RS232 and USB interface signals are isolated through photo-couplers.
Connecting to the Web site www.tecnoware.com it is possible to download free of charge the updated Management
Software for ATA, named WatchPower, compatible with the most popular Operating Systems.
It is possible to add an Interface RS485 (optional).
10.1 WatchPower
The management software WatchPower allows to monitor the operation of the system, to monitor the electrical
variables (current from PV panels, current from batteries, battery capacity, power output, working frequency and
other variables), to set the ATA functioning parameters, to record the data generated by the system, to see the
graphical representation of recorded data in function of time, and to extrapolate these data to an Excel file. You can
also set the alert by mail of any anomalies detected by the system.
