1. e f normal communication between the gateway and the AC module is established close all the circuit breakers except for that of the gateway and the AC module Disconnect the gateway from the AC module and re install it indoors e Verify that the connection between the gateway and AC module is maintained after the second installation The correct number of AC modules should now be visible from the app e Turn on one of the circuit breakers and wait 10 to 15 minutes Scan for the AC modules through the app If successful turn on another circuit breaker and scan for the AC modules Repeat until all circuit breakers are back on If you encounter an error while scanning the last circuit breaker is interfering with the communication 17 3 1 7 Connecting the Gateway to a Remote Router If the gateway cannot detect the installed AC modules it is recommended to move the gateway near the distribution panel for more reliable communication To do so the gateway needs to be connected to a remote router via PLC Bridge as illustrated below Power Line Adapter Broadband router PLC Bridge Server Power Line Adapter M 1 Connect the AC adapter from Power Port 12V 1A of the gateway to a dedicated 120VAC outlet 2 Connect the PLC cable from PLC IN Port of the gateway to a dedicated 120VAC outlet 8 Connect one of the power line adapters from the LAN Port of the gateway to a 120VAC outlet 4 C2. e The built in power line communication module is powered through the micro inverter Depending on the level of solar power generation the communication module might not receive sufficient power to communicate normally with the gateway Refresh the app during a different time e Communication errors can arise from the use of certain household devices Please try again after powering off the devices suspected of causing the problem If the error persists please refer to 3 1 1 Factors that Affect Power Line Communication 16 3 1 6 Checking for Interferences to the Power Line Communication e f there is still a problem with the connection between the gateway and the AC module it is necessary to check the factors causing interference e First connect the gateway directly to the AC module This will eliminate any potential interference caused by other devices normal communication should be achieved and the AC modules should be detectable by the smart phone app If the AC modules are still not detected on the app there could be a communication problem between the smart phone tablet and the gateway If you suspect that there is a problem with the gateway please request for a replacement unit It is recommended to install the gateway as illustrated in the figure below to prevent communication interferences PV Rack AC Module Trunk Cable gt Transition Cable AC Junction Box BR Equipment Es SN Grounding E General AC Conductor
