It will be the best if the outlet has shortest electrical path from the distribution panel where all of AC modules are attached. If the PLC level is zero or one, relocate the EnerBox2 to a location where few home appliances are installed. Refer to ‘5-4 Micro Inverter Detection Issues’ when relocation of EnerBox2 cannot solve problem.
AC Module System Installation Manual 5-4 Micro Inverter Detection Issues Troubleshoot power line communication issues as follows Issue : When the number of detected AC modules is not matched with the number of installed AC modules. ‘Detected AC modules’ is smaller than ‘Installed Number’. Follow below check list.. Rescan AC modules using the app and let the EnerBox2 find all of installed AC modules. Check LED status. or Check LED status Grid connectivity LED Status Grid connection (5 min.
AC Module System Installation Manual • ‘Detected AC modules’ is larger than ‘Installed Number’. • Follow below check list. Make sure that the number of installed AC modules is accurate in the activated system. Go for [Detected AC Module–Edit]. Then the bring the installation map where all of MAC address is attached. Compare it with the list in the app. Find and delete one which is not in the installation map. Then save it for update. Rev. 1.0 Copyright © 2017 LG Electronics. All Rights Reserved.
AC Module System Installation Manual 5-5 Internet Connection Issues Issue: Internet LED is Solid Amber or Off EnerBox2 INTERNET status LED While LG Electronics provide technical support on EnerBox2, LG Electronics has no responsibility on a router which is made by other manufacturer. If connection failure between the EnerBox2 and a router is occurred, check whether your laptop or mobile phone has no problem to use internet access at first. Take a quick measure by doing the steps below. A.
AC Module System Installation Manual Issue: How to set the static IP address. When an EnerBox2 tries to access to internet, it will automatically receive IP address from the router’s DHCP(Dynamic Host Configuration Protocol) server. However, based on circumstances, an EnerBox2 can manually set static IP address. 1. Push AP button for Soft AP mode. Refer to Method B, Notice #7. 2. Go for [Dashboard -> Network]. Then select WLAN or Ethernet. 3.
