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.
