Locus Energy LGate 320 Revenue Meter w/ 5 Year Monitoring Service LGate320-5YR

The LGate 320 is a three-phase electronic watt-hour meter for 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.

The LGate 320 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 installation regardless of panel or inverter type. The LGate 320 is a one-piece completely under glass meter which installs easily using a standard socket base. Performance data is uploaded in near real-time to the Locus Energy SolarOS 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 RS-485 or Zigbee connections. All data is stored in non-volatile memory and then automatically uploaded to the SolarOS and SolarNOC platforms.

Network Connectivity

The communications gateway inside the LGate 320 supports plug and play connectivity through a cellular or Ethernet network connection. Once the unit is installed and powered on, it will immediately begin transmitting data without any configuration. For maximum reliability, the communications gateway will automatically route uploads between the wireless and wired connections if either of the networks are unavailable.
