  • RS485

 Power Supply

  • 85~265V AC or 100~350V

The data transmission is accomplished via the RS485 port using an RJ45 cable with only 2pin wiring.
The energy meter is powered directly from the mains voltage and along with the current measurement, your inverter will know the exact power demand (in watts)

ACR10R Communication Cable Assembly

The RHI-5G Series inverter uses RS485 cable to communicate with the Meter and CAN tocommunicate with the battery's BMS. The image below shows the assembly of the RS485/CANcommunication cables.

Procedure for connecting the CAN cable:

1. Take out the CAN cable (terminal marks 'CAN' on one end and 'to Battery' on the other end).

2. Unscrew the swivel nut from CAN port.

3. Insert the RJ45 terminal with CAN label into the CAN port, then fasten the swivel nut.

4. Connect the other end to the battery.

Procedure for connecting the RS485 cable:

1. Take out the RS485 cable (terminal marks 'RS485'on one end and 'to Meter' on the other end).

2. Unscrew the swivel nut from RS485 port.

3. Insert the Two-pin terminal with RS485 label into the RS485 port, then fasten the swivel nut.

4. Connect the other end to the Meter.


Detailed Cable Connection

The following figure illustrates how to connect the three-phase meter to a Solis High Voltage Inverter.

Setp 1

The ports 5-6, 7-8 and 9-10 are the CT cable connections. Please ensure the CTs are connected with the correct polarity and the corresponding grid phase. Also, please note the small arrow inside the CTs, shall be pointed towards the Grid (5-6 to La, 7-8 to Lb, 9-10 to Lc)

Step 2

1,2,3 and 4 are the voltage detection ports. Please connect the ports with the corresponding grid phases (1 to La, 2 to Lb, 3 to Lc, 4 to N)

Step 3

12 and 13 are the auxiliary power source of the meter, 13 should be connected to the Neutral Wire(N) while the 12 should be connected to line La on the inverter backup output
