2.5.1 DRED CONNECTION
Anti-Reverse Function Connection
If BT system (connected with grid-tied inverters) requires anti-reverse function, it is operable but
please note:
1. This diagram is only for installation where has exporting power limit function requirement.
2. For anti-reverse function, will also need set on PV Master App
→
Advanced Setting
→
Power Limit.
3. This diagram only be reasonable if grid-tied inverter has anti-reverse function itself. And the power
limitation value shall be set on grid-tied inverter.
4. When using anti-reverse function, it would buy about 150W from the grid.
DRED is used for Australia and New Zealand installation (also used as remote shutdown function in
European countries), in compliance with Australia and New Zealand safety requirements( or European
countries). And DRED device is not provided by GoodWe.
Detailed connection of DRED device is shown below:
[1] This cable is a theoretical connection supporting anti-reverse function, which could be different for
different grid-tied inverters.
•Connection Diagram as below (Figure 2.4.2-8)
1. Put the cable through the plate as shown in Figure
2.5.1-4.
2. Wiring from the No. 5 and 6 holes respectively.
Connect DRED terminal to the right position onto
the inverter. (
Figure 2.5.1-5
)
Step 3-2 For Remote Shutdown
Step 1
Step 2
Step 4
Screw this plate off from inverter. (Figure 2.5.1-1)
Note: DRED device should be connected through
“DRED port” as the figure shows.
1. Plug out the 6-pin terminal and dismantle
the resistor on it (Figure 2.5.1-2).
2. Plug the resistor out, leave the 6-pin
terminal for next step.
Note: The 6-pin terminal in the inverter has
the same function of DRED device.
Please leave it in the inverter if no
external device connected.
1. Put DRED cable through the plate as shown in
Figure 2.5.1-3.
2. Connect DRED cable on the 6-pin terminal.The
function of each connection position
GoodWe BT series inverter complies with IEC 62109-2 13.9. Fault indicator LED on inverter cover will
light up and the system will email the fault information to customer.
