3-1-2 Cautions during Gateway Installation
• Power strips, surge protectors and outlet adapters can interfere with power line communication. Be sure to plug
the gateway directly to a power outlet.
• A lamp or light switch can contribute unwanted noise to the communication. Be sure to dedicate a power outlet for
the sole use of the gateway.
• Existing home appliances and other electronics can interfere with the gateway's power line communication.
3-1-3 Problems Checking AC Module through the Smartphone App
• If AC modules registered to a gateway cannot be accessed through the smart phone app, there is a
communication problem between the gateway and AC module.
• This could be a problem with the current outlet. Try to connect the gateway to a different outlet.
• Though the maximum communication distance range is 328 yds. (under optimal conditions), it is recommended to
install the gateway within 109 yds. (100m) of the AC modules.
• It is strongly recommended to have a dedicated outlet between the gateway and AC module. Appliances and
devices using the same outlet will disrupt communication.
3-1-4 Discrepancy of Installed AC Module Quantity on Smart phone App
• If the number of AC module on the app does not correctly reflect the number of installed modules, it is a possibility
that the AC modules are not fully operational due to insufficient power supply for communication. After checking
that energy is being generated in the modules, try scanning for the missing modules on the app.
• Scan for the AC modules during the day when they are generating energy.
• If the error continues, there is a problem with the communication connection. Please refer to 3-1-1 Factors that
Affect Power Line Communication.
3-1-5 Number of Registered AC Modules Fluctuating on Smart phone App
• The number of registered AC modules can change on the app for two reasons.
• 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.
• 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.
