Оptimises self-consumption and records the household‘s load curve on system with batteries
The Energy Meter can be used as a:
-
Grid meter, and used as control input for an
ESS System.
-
Measure the output of a PV Inverter.
-
Measure the output of a AC Genset.
For all above usages, the meter is connected to the GX device. For a full overview of all available & GX-compatible Energy Meters, read the Energy Meters Start page and Energy Meter Product page.
This chapter concerns the EM24 models using an RS485 data connection.
For wiring RS485, there are two options:
-
Direct connection, either using the RS485 to USB interface with 1.8m cable length, or the 5.0m cable.
-
Wireless connection via Zigbee
Multiple Energy Meters in one system
There are 3 options to connect multiple Energy Meters:
-
Each wired to a separate RS485-USB converter. Which are then each plugged into a separate USB socket on the GX device.
-
2 meters wired on to one RS485-USB converter. In this case the modbus address of the additional meter needs to be changed, so each is unique. See chapter 6.
-
Wireless connection: the additional meter is connected to an additional Zigbee to RS485 converters. There is then no second Zigbee to USB interface required. It is necessary to change of the modbus address of one of the AC sensors, see chapter 6.
Besides adding an extra sensor, it is also possible, in a single phase installation, to use the, unused, second phase to measure the output of the PV Inverter. See see the AC Wiring chapter in this manual.
This is a 65A three-phased meter has the following product details
