Standard three-phase installation measuring power coming from a power utility (grid) and from a single-phase solar-system inverter. The color coding shows 120/208V, but applies to 277/480V as well. This diagram is for a Wye system with a neutral. Refer to delt...

Basic installation measuring power coming from a power utility (grid) and from a single-phase solar-system inverter   Registers: Notes: With a single-phase inverter, the current flowing at any given instant on leg L2 is the negative of the current fl...

Same as Standard Split-Phase installation, except that the inverter feeds directly into the power utility’s grid. That is, the Solar CT is closer to the utility than the Grid CTs. This situation often arises when solar power is delivered via a line-side tap. ...

Three-phase high-leg delta installation measuring power coming from a power utility (grid). Registers: Notes:  Wiring and configuration is identical to a standard three-phase site. The only difference is in the voltages measured on L1, L2, and L3: – L...

Three-phase delta installation measuring power coming from a power utility (grid). The color diagram below shows a 208V delta, but this also applies to a 120V delta or 240V delta. Registers: Notes:  CAUTION: Since there is no neutral and none of the p...

This example illustrates how to measure subpanels. Registers: Notes: It does not matter which subpanel the meter obtains voltage from, but care must be taken to identify correct phasing. It is possible for phases to be reversed or inconsistent between...

This example illustrates how to configure 120Vac (single pole) and 240Vac (two pole) appliances. Registers: Notes: Registers defined for appliances do not appear in the totaling rules. Just defining the registers will make them appear in the appropria...

You'll need either a Wi-Fi enabled laptop computer or cell phone/tablet to complete this process.  Make sure your computer is not using any other network connection such as Ethernet before beginning. Connecting the EG42xx meter to a Wifi Network After poweri...

 Visit the online store page (EG4215 or EG4230) Model: EG42xx The EG42xx meter series contain embedded WiFi. Normally, the meter connects to a WiFi network to provide network and internet access. However, the meter can also temporarily act as an access point...

Firmware versions and relase notes may be found at egauge.net/revs Minimum firmware version The eGauge JSON-based WebAPI was introduced in meter firmware v4.2. However, it is recommended to use the most recent meter firmware as there have been multiple b...

What is a proxy server? A proxy server provides remote access to an eGauge meter which may be connected behind a firewalled network. The proxy connection is initiated outbound, which in most cases allows for remote access without the trouble of configuring fir...

EG4xxx meters have full TLS 1.2 support. Proxy-server HTTPS support Legacy meters do not support encryption between the meter and proxy server. However, encryption may be supported between the proxy server and the client requesting data. HTTPS Support and ...

What is Unix time? Unix time is simply a numerical value of the number of seconds that have elapsed since January 1, 1970, midnight, UTC. This date is called Unix epoch. Unix epoch is not to be confused with the eGauge or meter epoch, which is configured in Se...

eGauge meters in the EG4xxx line feature an integrated LCD display which can be used to view data and makechanges to the device configuration. Navigation is handled through the small control toggle located to the leftof the CT ports. The control toggle has thr...

When connecting to an EG42xx meter with some Samsung mobile devices the 'Manage router' option is not immediately visible in the WiFi network settings. This has to do with how the Samsung software handles captive portal login. To force it to show, try these s...

The Export function is used to export register data in .csv file format. This function is available in Firmware v.4.6 and later and is available as a standalone menu item and as a Dashlet. Access the Export function from the Main Menu by choosing Export d...

Introduced in Firmware v4.6, the Dashboard Manager is used to view the list of existing dashboards on an eGauge meter.  From this page you can also create a new dashboard, make a copy of an existing dashboard for editing and delete Dashboard views that are no ...
