11.9 METER DTSU SETTING
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 “600
” will appear, press the ”→” key
once to write the number “601”.
2. Press “
SET
” twice to move the cursor left,
highlighting “601”;
3.
Press the “→” key once more to write the number “
701”
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 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 “10”
c.
Press the “→” key repeatedly until the number “
40” 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.
11.10 CHECKING THE CORRECT READING OF THE METER DTSU
1.
The Power Factor values for each phase Fa, Fb and Fc
(phase shift between voltage and current) are between
0.8-1.0. If the value is lower, move the sensor to one of
the other two phases until the value is between 0.8-1.0.
2.
The Pa, Pb and Pc Powers are:
•
Greater than 1 kW.
•
In line with the home consumption.
•
The sign in front of each value is negative (–).
In the case of a positive sign, reverse the direction of the
toroidal winding in question.
In order to verify the correct reading of the
meter on exchange
, make sure that the hybrid inverter and any other PV production sources are switched off.
Switch on loads greater than 1 kW for each of the three phases of the system.
Stand in front of the meter and use the “→” keys to scroll through the items, and “ESC” to go back, checking that:
In the case of a
meter for reading the production of existing photovoltaic systems
, repeat the previous steps :
1.
Check the Power Factor as described in the previous case.
2.
This time the sign of the powers must be positive for Pa, Pb, and Pc
3.
Switch on the Hybrid Inverter, check that the total PV power value (Pt) is in line with the value shown on the inverter's display.
