Overview It's common to find sites with large stepdown transformers (e.g. to convert a 277/480V service to 120/208V for lighting or receptacle loads). To measure any AC load, the eGauge requires a combination of voltage references (Lx voltage terminals) and a...

Overview The 347/600Vac wye service (347V phase to neutral, 600V phase to phase) is rarely seen in the USA, although it's quite common in Canada. As the eGauge is only rated for 277Vac from phase to neutral (480V phase to phase), it traditionally could not be...

Overview The EG4xxx meter features a low voltage terminal (Ldc) which can be used to measure 9-60Vdc (12-60Vdc is required to power the meter from the Ldc terminal). However, there are many monitoring applications where DC voltage exceeds 60Vdc. String-based ...

Overview The IMT Weather Station model Si-RS485TC-2T-v-MB (referred to as the IMT sensor for the remainder of this article) is a high accuracy irradiance and cell temperature sensor. Optional attachments can be connected to monitor windspeed and ambient tempe...

Starting in firmware v4.2 a custom HTTPS certificate may be uploaded to the meter and used for local HTTPS webserver access. This does not affect the proxy-server access (e.g., https://eGauge9999.d.egauge.net , https://eGauge9999.egaug.es or https://egauge9999...

Overview All eGauge meters use NTP (Network Time Protocol) to obtain the current date and time. The exact process used depends on the meter hardware version (eGauge2, EG30xx, EG4xxx). Access to an NTP server isn't required, but it is highly recommended to ens...
