6 1 Safety Note and comply with the safety guidelines of this manual while handling AC modules. Failure to comply may result in severe damage to the equipment and/or fatal injuries. Safety symbols are used to minimize loss and injury during handling and operation of the equipment specified in this manual.
7 WARNING • EnerBox warranty void if cover removed. No serviceable parts inside. Refer servicing to qualified personnel. • To avoid communication interference, do not connect the product to power strips, surge protectors, or surge protector-embedded power strips.
8 Ex) App Messages Scr een Ex) W eb Array View Scr een 1 Date 2 AC module ID 3 Message type 1 2 3 The app shows real time status of the AC modules under AC Module Status and System Status, as well as Array View and Events through the monitoring web server.
9 1 Current Issues : Provides the current conditions of the system. 2 Event History : Provides the event records for aspecified period. 3 Click the device in the query results to check the “Issue Details”.
10 • Check the wirings to see if the connection is ok. The conductors in the cables may have been damaged or cut. • Check if the connector connection is ok. The connector may be broken or connected improperly. • Check that there is not discrepancy between the real grid voltage and the voltage setting in the installation app.
11 Notice #3 AC Frequency Changing T oo Fast • Occurs if system voltage is lower or higher than the operational threshold. It is usually caused by a problem with the energy company. It may be a temporary problem, and is automatically corrected by the energy company.
12 Error #1 DC V oltage High Error #2 DC Current High • Occurs if the AC module DC input voltage is higher than 50V. • Occurs if the AC module input current is higher than the limit. DC Voltage Operation Range 20 to 45 VDC Max. Input Operating DC current 12 ADC • Check for possible damages in the module and microinverter.
13 Error #3 AC Current High • Occurs if the AC module output current exceeds the operational threshold. Ex) AC Curr ent High Screen Nominal Voltage 240 Volt AC Nominal Voltage 208 Volt AC Max. Output AC current 1.27A AC Max. Output AC current 1.44A AC Error #4 Inverter Failur e • Occurs if AC module malfunctions.
14 Error #5 T emperatur e Protection • Occurs if the internal temperature of the inverter is outside of the operation range; operation will automatically be stopped. Ex) T emperatur e Prot ection Screen • Check that the operational ambient temperature is within the operational range.
15 3 Gateway and Communication Issues • Power strips or surge protectors in the same circuit. • UPS (Uninterruptible Power Supply) or Battery backup units in the same circuit. • Lamp dimming switches. • Power line communication-based home networks or home automation devices.
16 • 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.
17 • If there is still a problem with the connection between the gateway and the AC module, it is necessary to check the factors causing interference.
18 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.
19 If you hit the Registration button before listing all AC modules, or you need to add the unlisted AC module, follow steps below. 1 Enter LGElectronics (initial password) on the blank box in figure and press EnerBoxGroupchage button toreturn the gateway to the initial condition.
20 3-1-1 1 Registering a Replacement AC Module to the Gateway If you need toexchange an AC module, follow the steps below. 1 Enter LGElectronics (initial password) on the blank box in the figure and press the EnerBox Group chage button to return the gateway to the initial condition.
21 4 Gateway and Communication Issues 4-1 Network Configuration Troubleshooting Web Server Communication Errors • Check the LAN cable connection to the wired LAN port. If necessary, reconnect. • Check the hub or router settings. • Check the smart phone app settings.
