LGate - Model 120 - Single-phase Electronic Watt-hour Meter
The LGate 120 is a single-phase electronic watt-hour meter for the remote monitoring of solar photovoltaic systems. It features a smart communications module to automatically transmit meter data over cellular or Ethernet networks, allowing system owners and operators to easily manage distributed solar assets.
Product Overview
The LGate 120 combines a revenue-grade, solid-state power meter with an advanced communications gateway. These components work in conjunction to remotely monitor the performance of residential solar energy installations regardless of panel or inverter type. The LGate 120 is a one-piece meter completely encased in a NEMA 3R-rated housing, which installs easily using a standard socket base. Performance data is uploaded in near-real-time to the Locus Energy SolarNOC™ monitoring platform, which provides a suite of tools and analytics for asset managers.
Data Collection:
AC energy data is collected by the meter and passed to the communications module. Additional system performance data can be collected directly from meteorological sensors and supported inverters via available RS-485 or Zigbee interfaces. All data is stored in non-volatile memory and then automatically uploaded to the SolarNOC platform.
Network Connectivity:
The communications gateway inside the LGate 120 supports plug-and-play connectivity through a cellular or available Ethernet network connection. Once the unit is installed and powered on, it will immediately begin transmitting data via the cellular network without any configuration. The communications gateway can be alternatively configured to bypass the cellular mode so that it automatically routes uploads using wired connections.
