RJ45 terminal connection sequence and definition as shown in table 4-37.
4.4.3 Communication between inverter and battery
The communication between meter and inverter is an RJ45 interface cable. A 3M length
battery communication cable is already attached to the inverter when you received it, and you
just need to insert it to the BMS interface of the inverter and battery.
4.4.4 Multiple inverters parallel connection/EMS/Relay output dry contact
Multiple inverters parallel connection, EMS and relay output dry contact interfaces use the
6pin terminal on the right side, and you can use the matching 6pin terminal in the accessory
box to make the connection, as shown in Figure 4-38.

1) The EMS communication between inverter and battery should be connected through the
RJ45 cable that is attached to the inverter when you need to control the work of the hybrid
inverter.
Figure 4-39 EMS communication wiring diagram
2) Sunways STH 4~12kW series hybrid inverter integrated a set of relay output dry contacts
with the contact capacity 230Vac/1A or 30Vdc/1A that are very useful in some special
circumstances, such as in the purely off-grid system, it can be used to trigger the backup
generator. Please contact your installer or Sunways service team to learn more detailed
operation steps.
4.4.5 DRED Connection
DRED interface is special reserved for Australia and New Zealand according to their safety
regulation, and Sunways doesn’t provide the DRED device for the customer.
DRED connection uses the 6pin terminal on the left side, and you can use the matching 6pin
terminal in the accessory box to make the connection, as shown in Figure 4-40.
