3. ECU Network Settings (This step can be skipped)
3.1 For wired connection, use an Ethernet cable to connect the ECU's LAN port to the router's WAN port. No configuration is needed for internet
connection.
3.2 For wireless connection, select the router you want to connect to and enter the router's connection password. Click on "Setting" to complete
the network settings.
4. Inverter Networking
After completing the inverter binding and network settings, wait for the inverters to complete networking. The progress of networking can be
viewed in "Inverter" - "Network". The time required for networking depends on the number of inverters and the installation environment. Once
the networking progress reaches 100%, the ECU initialization is completed. At this point, you can check the system's operational status in the
"ECU" and "Inverter" interfaces.
Step 4: Perform remote or local monitoring.
Remote monitoring: After you log in to your registered account, you can monitor the system remotely.
Local monitoring: Connect to an AP hotspot and tap Local Access to monitor the system locally.
FAQs
Q: If I enter a wrong inverter UID or the inverter needs to be replaced, how do I modify the inverter UID registered on the ECU?
A: Log in to your EMA account, and tap Local Access > Setting > Link Inverters. On the page that appears, you can delete the inverter UID to
be modified and add new UIDs. Tap Binding to complete the binding of the new inverter. If the wrong inverter UID has been registered to a
user account before replacement binding, contact the distributor or APsystems to update the account information.
Q: What do I do if I cannot tap ECU Information or Inverter Information when I register for an account?
A: You need to enter the account information, ECU information, and inverter information in order.
Q: What do I do if the system prompts that the registration fails after I tap Complete Registration?
A: Check whether your phone is switched to a 4G/5G network or connected to a router.
Q: What do I do if the system fails to find a device connection during ECU initialization?
A: Make sure that your phone is connected to the Wi-Fi hotspot of the ECU to be initialized.
Q: How do I check whether Wi-Fi pairing is successful during initialization?
A: You can check whether the network connection is successful on the Network Configuration page.

Step 5: CT (Current Transformer) Installation
The position of the CTs: Clamp the CTs on production lines from PV system and import/export lines from public grid.The direction of CTs: The
arrows on the CT should point from grid to PV system and from grid to distribution box.The wiring of the CTs: White wires connect to "+"
Production CT ports on ECU-C and black wires connect to "-" Grid CT ports on ECU-C.CTs are as optional accessories provided, to ensure the
CTs could match APsystems ECU-C, please purchase CTs from APsystems or APsystems distributors.80A and 200A CTs are available.
