  • Page 3: Important Product Information

    Disconnect the LGate 120 from the power source (both the breaker to the LGate and the AC disconnect) when servicing the product. The LGate is not intended for use in life-support applications.

  • Page 5: Revenue-Grade Monitoring

    This type of monitoring works with single-phase inverters and power sources up to 200A. IMPORTANT: The LGate 120 does not ship with a meter socket included. For proper installation, the LGate 120 meter must be mounted in an installer-supplied meter socket that meets the following specifications: ...
  • Page 6 2. Connecting to the Internet The LGate 120 requires a network connection to communicate. The cell modem is the primary method of communication; if there is no cellular reception or using the cell modem is not an option, then use the secondary method, installing an Ethernet cable.

    2. Blinking slowly: The last data packet was not sent successfully and the cellular signal strength (if applicable) is weak. No phone icon: The LGate 120 is not connected to the network. For an Ethernet cable connection, double-check the pin-out on the Ethernet cable (see the FAQ section on page 31 for more information).
  • Page 8 5. Reading Verification Check that the energy (kWh), power (kW), and current (A) readings that cycle on the LED screen match the inverter output. If power readings are negative, the meter socket was installed backward. Verify that the inverter wires running through the meter socket go from line side to load side (top to bottom).

    The ability to log into the LGate with a laptop to view configuration settings. Logging into the LGate 1. Reset the LGate 120 by turning off the AC disconnect and breaker to the LGate for 30 seconds, then back on again.
  • Page 10 (see below) Enabling the Ethernet Connection The LGate 120 comes preconfigured for a cellular connection. If the cellular option is not possible, enable the Ethernet Connection by selecting false in the Cell Mode drop-down menu and the Save Configuration button.
  • Page 11 The LGate can be configured for either a dynamic (DHCP) or static IP address (on a LAN connection only).  A dynamic IP address allows the router to assign the LGate 120 an IP address automatically. If using the cell modem, the LGate can only use a dynamic IP address. ...

  • Page 12: Inverter Direct Monitoring

    Inverter Direct Monitoring Inverter direct monitoring is a monitoring feature that some companies purchase in addition to the core monitoring package. This feature should only be installed if it has been ordered for this particular project. If you are unsure if inverter direct monitoring has been purchased for this project, contact your company, lease provider, or program administrator.
