10.3.1 SETTING DTSU METER
To configure the device in read mode on the exchange, enter the settings menu as shown below:
•
Press
SET
and the word
CODE
will appear
•
Press
SET
again
•Enter the number “701”:
1.
From the first screen where the number “60
0
” will appear, press the ”→” key
once to write the number
“60
1
”.
2.
Press “
SET
” twice to move the cursor left,
highlighting
“
6
01”;
3.
Press the “→” key once more to write the number “
7
01”
Note
:
In case of error, press “ESC” and then “SET” again to reset the required code.
•
Confirm by pressing
SET
and to enter the settings menu.
•
Enter into the following menus and set the parameters indicated:
1. CT
:
a. Press
SET
to enter the menu
b.
Write “40”:
a.
From the first screen where the number “
1
” appears, press the ”→” key repeatedly until the number “1
0
” is written.
b. Press
SET
once to move the cursor left, highlighting “
1
0”
c.
Press the “→” key repeatedly until the number “
4
0” is written.
d.
Press “ESC” to confirm and “→” to scroll to the next setting.
Note
: In case of error, press “SET” until the thousand digit is highlighted and then press “→” until only the number “
1
” is displayed;
at this point,
repeat the above procedure.
2.
ADDRESS
:
a. Press
SET
to enter the menu:
b.
Leave “01” for Meter on exchange
c.
Write “02” (by pressing “→” once from screen “01”). With
address 02, the inverter assigns the data sent by the meter as
production power. A maximum of 3 meters can be set for the
production (Addresses 02, 03 and 04)
d.
Press “ESC” to confirm.

Note
: In case of CT sensors other
than those supplied, enter the
correct transformation ratio.
10.3.2 CHECKING CORRECT DTSU METER READING
1.
The Power Factor values for each phase Fa, Fb and Fc
(representing the phase shift between voltage and
current) fall within the range of 0.8 to 1.0. If the value is
lower, move the sensor to one of the other two phases
until the value falls within the specified range.
2.
The Pa, Pb and Pc Powers are:
•
Greater than 1 kW.
•
In line with home consumption.
•
The sign in front of each negative value (
–
).
In the case of a positive sign, reverse the direction of the
toroidal winding in question.
In order to check the correct reading of the
meter on exchange
, turn off the hybrid inverter and any other PV production sources.
Activate loads greater than 1 kW for each of the system's three phases.
Stand in front of the meter and use the “→” keys to scroll through the items, and “ESC” to go back, checking that:
For meters used to read the production of existing photovoltaic systems
, repeat the previous steps as follows:
1.
Check the Power Factor as described in the previous case.
2.
This time, ensure that the sign of the powers (Pa, Pb, and Pc) are positive.
3.
Switch on the Hybrid Inverter, and check that the total PV power value (Pt) matches the value displayed on the inverter's screen.
