1.3 The SEC1000: current transformers
Connecting the current
transformers.
•Current Transformers (CTs) are not included in the SEC1000
•CTs must be appropriate to the electrical installationwhere they will be installed
•They must be installed in an ideal location to record the import/export flow
•For your selection,special attention should be paid to:
•Installation in bars vs wiring
•Primary (X/5 A): suitable for the maximum current of the entire installation(not just PV)
•Secondary (X/5 A): 5 amps
•Recommended open-core CT for easy installation
Example of open core current
transformers.

Step 1:
•Check the connection status with the equipment
•Connection Succeeds: correct
•Connection fails: failed
•Close and open Promate
•Repeat the "Reset" step, if necessary
•Check the correct upgarde of the FW
•FW ≥ V1.09: correct
•FW < V1.09: incorrect
•Repeat the upgrade
Confirm version FW

Step 2:
•Activate the corresponding COM port
•Indicate the number of connected inverters (RS485) on the
activated port
•Confirm
Step 3:
•Refresh the list of inverters
•Check that all inverters connected via RS485 are displayed
•If an inverter is missing, you must check that it is correctly
installed and connected to the RS485

Step 4a:
•Click on the "Export Enab" box
Step 4b:
•Indicate the power of the PV system in the "Total Capacity" field
•Indicate the export power to the grid in the "Power Limit" field
•Without grid export: "0 kW"
•With export to grid: P Limit > P Total Capacity
•Confirm “Set”
Step 4c:
•Indicate the ratio of the current transformer installed
•Confirm “Set”
•Confirm “Get Data”
Step 4b (cont.):
•Select the corresponding analysis option
•Scan each phase: by phase
•Scan total of three phases: for the total number
of phases (suggested)
•Confirm “Ok”
Step 4c (cont.):
•Check the values
•Power (+): export of energy to the grid
•Power (-): import of energy from the grid
•If there is any inconsistency, check the installation of the CTs

Static IP
•Watch the LED
Step 6:
•Disconnect the computer from the SEC1000
•Connect the router cable to the ethernet port of the EzLoggerPro
Step 5A: Static IP
•Indicate the IP of the router
•Indicate the Subnet Mask, if necessary
•Indicate the DNS, if necessary
•Confirm “Set”
5A
Step 5B: Dynamic IP
•Check the "DHCP Enable" box
•With dynamic IP, the IP and mask are automatically
assigned by the router
•Confirm “Set”
5B
Dynamic IP
•Press the Reset button (pr > 5 sec.)
•LED sequence from left to right
•Watch the LED “Server”
LED “Server”:
•On: connecting and communicating correctly
•Flashing: communication failed, check assigned IP
•Off: connection failed, check the connection to the router

•In order to be able to display the consumption and meter curves, the firmware (FW)
of the EzLoggerPro must be upgraded, using a USB memory stick.
•If necessary, you must update the SEC1000 using a USB stick.
You need:
•USB Memory Stick
•GoodWe Firmware File*
Steps:
1. The USB stick must be empty
2. Save the FW file to the root of the USB
•No folders or other documents should be on the USB
3. Turn off the AC switch
4. Insert the USB stick into the USB port of the EzLoggerPro
5. Turn on the AC switch
•The LEDs remain lit during the upgrade
6. Wait until the LEDs flash (approx. 2 mins.)
7. Retract USB stick
8. The upgrade has been completed

3.1 How to upgrade the Firmware
Data may change without prior notice

•The SEC1000 must be added to the FV plant in SEMS next to the inverter(s).
•The correct display in the SEMS Portal must be checked.
Steps:
1. Confirm that the SEC1000 has been added to the plant correctly
•SEMS > Settings > Plant setup > Device management
2. Status SEC1000:
a) Online: correct
b) Offline: check for proper communication:
i. SEC1000 - router
ii. Router - server
3. Check the curves shown at the PV plant
a) If the load curve is shown overlapping the PV generation curve and/or the meter curve is
shown flat (image 2), you must check the correct installation of the CTs (polarity)
b) If the curves are shown independent but inconsistent, you must check the correct
installation of the CTs (location) and/or the indicated CT ratio (step 4c)
c) If the curves are shown independently and coherently (image 3), the installation and
display is correct
4. The check has been completed
Image 1: status SEC1000.
Image 2: Incorrect PV system curves.
Image 3: Correct PV system curves.
4.1 Check the SEMS Portal

4.2 Check the CT
•The correct setting, location and direction of the current transformers (CT) should be checked
•CTs must be installed near the meter.
Checking the displayed real time data:
1. Turn OFF the PV system
•The energy consumed is supplied by the grid (import)
2. Refresh “Get Data” in Promate
• “RealTime Data” window will be displayed
3. Check the power values shown
•Power (+): energy-to-grid export impossible scenario (system OFF)
•Check the installation (direction) of CTs
•Power (-): importing power from the grid correct
4. Check the consistency of the displayed values*
•Check the “CT ratio” of the installed transformer (observe 4c)
•Check the correlation between the measured phase (voltage) and its CT
4c
* Ref.: Pi x Ii x Vi x Cos φ (± % measurement accuracy) under balanced conditions
