Grid & EPS
4.3.1 Grid terminals (Grid)
The Terminal Blocks labelled as “Grid” connects the SunRise directly to
the Grid in the MSB. (Also review wiring diagram included in Appendix A)
To connect the cables to the system, pass them through one of the outlets
in the rear of the SunRise (use the glands provided which are designed to
seal around 25mm conduit) secure the exposed end of the cable into the
correct terminal block, observing the 3-phase rotation warning label.
Tighten with a flat-head screwdriver to 0.5N•m.
4.3.2 Emergency Power Supply terminals (EPS)
The Terminal Blocks labelled as “EPS” identifies the connection point that
remains live during a Black-out. In the MSB you will connect loads to this
output that are to continue operating during a black-out. Do not overload
the EPS circuit in the MSB with not-essential loads
As the output is floating, the neutral cable of GRID side and EPS side must
be connected together according to the wiring rules AS/NZS_3000.
Otherwise, EPS function will not work. See Appendix A: Single Line
Diagram – Main Switchboard.
4.3.3 MSB - Main switch board setup
After the installation of the three-phase SunRise, the Main Switchboard
of the property should look something like the diagram below. The three
key components related to your SunRise system are identified below:
1.
SunRise Meter (CHINT or Sungrow version): This measures the
amount of power imported from, or exported to the grid (see section
4.4 for details)
2.
“MAIN SWITCH ESSENTIAL CIRCUIT SUPPLY”: Disconnects the non-
essential loads of the SunRise
3.
“MAIN SWITCH BESS SUPPLY”: Disconnects the essential load output
of the SunRise. This is where the loads are connected that you want
operational during a blackout.
Note that the two MAIN SWITCHs identified above are there for use during maintenance on the SunRise
System or the main switch board itself.
