XSTORAGE HOME POWER METERS MANUAL

   MN700001EN   March 2019   www.eaton.com/xstorage

Figure 26 shows how to wire the power meter to the RS-485 

port of the communication card located on the lateral surface 

of the hybrid inverter. This enables the Modbus functionality. 

There are two power meters: power meter 1 (EM1) measures 

the AC power injected from the grid to power up the non-

critical loads and power meter 2 (EM2) measures the AC 

power generated from the existing PV system. The energy 

meter is connected to the terminal RS485 of the xStorage 

Home system with a 1 mm

2

 cable.

• 

EM2: Please wire the terminal (10) of the EM2 to the 

terminal (3) of the RS-485 port. Please wire the terminal (9) 

of the EM2 to the terminal (4) of the RS-485 port.

• 

EM1: Please wire the terminal (10) of the EM1 to the 

terminal (1) of the RS-485 port. Please wire the terminal 

(9) of the EM1 to the terminal (2) of the RS-485 port. EM1 

should be wired after the configuration is finalized.

the RS-485 port of xStorage Home

To finalize the set-up of the power meter it is important that 

the appropriate meter is selected from the user interface. The 

procedure starts with EM2 and then needs to be repeated 

for EM1. Please refer to the xStorage Home user interface 

onboarding process manual to setup the meter in the user 

interface.
Please hold the button for three seconds, the meter will get 

into set-up mode as it is displayed in the picture below.

Figure 27: Set-up mode of the power meter

Once the meter is on SET mode as described, please be sure 

that from the user interface the right power meter is selected. 

The addressing between the power meter and xStorage Home 

is automatically made and the auto configuration is finished. 

Please refer to the user interface onboarding process manual 

to setup the meter in the user interface.
It is possible to verify that the process is successfully finalized 

also from the energy power meter display.
For the second power meter EM1 repeat all the steps 

previously made for the power meter EM2. Please note that 

it is only possible to setup EM1 after finalizing the installation 

of EM2. This means that the Eastron power meters are in SET 

status one at a time. If both meters are in SET mode during 

the installation, then addressing issues will occur. Follow 

the onboarding process of the user interface to finalize the 

installation of the power meters.
