Figure 2-11 Wiring diagram

Figure 2-12 Interface terminal diagram

1. Overall wiring

As can be seen from the figure above, the three CTs and AC voltage sampling lines need to be placed between the load and the grid to detect the power of the grid-connected access point in real time. The ShineSEM-XA-R is recommended to be installed near the power distribution cabinet of the grid. The CT and AC voltage sampling lines are placed in the power distribution cabinet.

2. RS485 interface

The ShineSEM-XA-R is used to connect the RS485 interface of the inverter. For the wiring method of multiple inverters, please refer to the following figure. The precautions are as follows:

(1) The RS485 wire is recommended to use twisted-pair shielded wire, and the shielding layer is connected to the GND pin of the RS485 interface of the ShineSEM-XA-R and the inverter.
(2) A maximum of 12 inverters can be connected, that is, n≤12. Refer to the wiring diagram and connect them hand in hand.

(3) The collector and the inverter should be connected in a hand-in-hand manner, and the RS 485 interface of the last inverter should be connected to the grounding terminal of the casing to prevent the 485 communication from being interfered.
(4) Power cables, power cables and communication cables must be placed in different trenches to prevent power cables and other cables from running parallel for long distances and reduce electromagnetic interference caused by instantaneous crossover of output voltages. When running RS485 cables and power cables in parallel, the distance should be greater than 0.5 meters.

3. Current transformer interface

There are P1 and P2 silk screens on both sides of the current transformer to distinguish the direction. Refer to Figure 2-5 for wiring. The P1 side is close to the grid, and the P2 side is close to the inverter and load. The transformer connection method is as follows:

(1) S1 of inverter L1 phase current transformer CT1 is connected to CT1's"+', S2 is connected to CT1's"-".
(2) S1 of inverter L2 phase current transformer CT2 is connected to CT2's"+" , S2 is connected to CT2's"-".
(3) S1 of inverter L3 phase current transformer CT3 is connected to CT3's"+" , S2 is connected to CT3's"-".

Precautions:

(1) Before the transformer is installed, its secondary must be connected to the ShineSEM-XA-R to ensure that the secondary of the transformer is not open.
(2) If the on-site primary busbar is a cable, professional electrical personnel can carry out live installation; if the primary busbar is a copper bar, the live operation requires a relatively high level of proficiency for the operator, and insulation protection measures are required.
(3) When installing the transformer, foreign matter such as impurities and dust must not fall into the cutting surface of the iron core, so as not to affect the performance of the transformer.
(4) If the ShineSEM-XA-R is not equipped with an ammeter, no current transformer needs to be installed.

4. Voltage sampling interface

Connect the voltage sampling line as shown in Figure 2-7. According to the three-phase four-wire wiring method, L1/L2/L3/N must be connected, otherwise the ShineSEM-XA-R will not work properly.

5. Network cable interface

Pull a network cable from a router with a network, and plug it directly into the ring network switch of the communication box of the smart subarray. This interface is used for remote monitoring. For details, please refer to Chapter 5.

6. Ground terminal

To ensure the reliable operation and personal safety of the ShineSEM-XA-R, the ground terminal on the housing must be reliably grounded.

Note: Pay attention to the waterproofing of the ground terminal.

2. Feed-in power: the power allowed to be fed to the grid (only the PV power can be exported to the grid, not the battery power)
3. Fail-safe protection power limit: the power (%) of the PV inverter or storage inverter in case that the power adjustment fails
4. Failure time: time limit within which the communication between the PV inverter, storage inverter and datalogger is disconnected. If the datalogger constantly fails to communication with the PV inverter and storage inverter within this duration, the PV inverter and storage inverter will enter the Failure State.

Note:

• The residential storage inverter carries out load compensation during power adjustment. Whenever the load is consuming power, the datalogger will adjust the storage inverter and the PV inverter to perform load compensation, which is not affected by the pre-set value of power drawn from the grid.
• The WIS Commercial and Industrial Storage Inverter mainly compensates the grid power. It carries out grid compensation when the power imported from the grid exceeds the pre-set value.
• Two types of Failure State:

(1) If the communication between the datalogger and the export limitation meter is abnormal, the datalogger will set the PV inverter and storage inverter into the Failure State and operate at the failure power level. This status can only be cleared by the datalogger.

Figure 3- 32 Time mode settings

Multiple time mode settings. You can select Special Day 1, Special Day 2, Quarter (1, 2, 3 4) or Full year, as shown below:

Figure 3- 33 Time mode settings

Procedure to set the working mode for idle time is illustrate below:

(1) Add a time segment. When the cursor is on the Start Time (00:00) filed, the "x" icon will be displayed, as the following figure shows.

Figure 3- 34 Idle time settings

(2) Click the "x" icon, then you can set the working mode for idle time based on the inverter model and on-site situations.

Figure 3-35 Idle time settings

(2) If the datalogger fails to communicate with the PV inverter and PCS over the failure time, the PV inverter and storage inverter will enter the Failure State and operate at the failure power level. When the communication is re-connected, the PV inverter and storage inverter will exit the Failure State.

3.1.6.2 Meter configuration

Figure 3-30 Meter configuration

1. When the power meter is enabled for power adjustment, the power value of the meter will be read every 100ms.
2. Meter CT: Select the CT configuration of corresponding specifications based on on-site situations (the CT ratio can be customized). If the ShineMaster4G-X is integrated in the SEM-X, the CT has been configured before delivery, therefore configuration of the CT is not required and the default value is "No". This is only for the export limitation meter.
3. Port: The default value is RS485-2 for the export limitation meter. You can select the RS485 route based on the actual wiring situation.
4. Meter type and address: Select the corresponding value based on the actual wiring situation. The default address value is 2 for the Eastron three-phase meter; 4 for the CHINT three-phase meter.

3.1.6.3 Adjustment management

Figure 3-31 Adjustment management

This setting item is to set the power adjustment mode:

• Total Phase Adjustment: read Phase A, B and C power of the meter or the total power. Adjust the power of the PV inverter or storage inverter based on the total-phase power and direction.
• Minimum Phase Adjustment: read Phase A, B and C power of the meter. Adjust the power of the PV inverter or storage inverter based on the minimum phase power and direction.

- Single Phase Adjustment: read Phase A, B and C power of the meter. Adjust the power of the PV inverter or storage inverter based on the power and direction of each phase.

Note:

(1) If set to "Disable", the adjustment mode is "Total Phase Adjustment" by default.

(2) If all inverters installed on site are PV inverters, you cannot select Single Phase Adjustment. The Single Phase Adjustment function is not available for PV inverters and you can only select Total Phase Adjustment or Minimum Phase Adjustment.

3.1.6.4 Time mode settings

Time mode settings is about defining the working mode of the storage inverter during different time segments. The main working modes are described below:

- Load First: prioritizes supplying power to the loads. Both PV power and battery power can be used for supporting the loads. When importing power from the grid to power the loads, the storage inerter will output corresponding power for compensation. When exporting power to the grid, it should not exceed the Feed-in Power.

- Battery First: prioritizes supplying power to the loads. Both PV power and battery power can be used for supporting the loads. When the load power is less than the permitted power drawn from the grid, it will adjust to charge the battery. Charging power range: load power + battery charging power < permitted power drawn from the grid. In case that the power drawn from the grid exceeds the permitted value, it will reduce the battery charging power. If there is any surplus PV power, it can be fed to the grid, which should not exceed the pre-set feed-in power.

- Grid First: prioritizes supplying power to the loads. Both PV power and battery power can be used for supporting the loads. The surplus power will be fed to the grid, which should not exceed the pre-set feed-in power.

- PV-only storage: prioritizes supplying power to the loads and the battery is not allowed to discharge. The PV power can charge the battery, but the grid power cannot charge the battery. The excess PV power can be fed to the grid. Both PV power and the AC grid power can be used to supply power to the loads. In the off-grid mode, the battery will discharge to power the loads. If the battery energy is not available and an SYN (ATS) is installed, the generator can supply power to the loads.

- Battery Idle Mode: the battery does not charge or discharge power. The PV power is used to support the loads, and the surplus PV power can be fed to the grid. It is allowed to draw power from the grid to power the loads. For backup power during power outage, in the off-grid mode, the PV power and battery power are used to power the loads.

- Standby Mode: the storage inverter does not charge or discharge the battery. Configure the 9 time windows. Select the appropriate working mode for each time segment based on actual demands.

Note:

1. During idle time, the working mode is set to Standby Mode by default if not configured. Idle time: all time that has not been configured.
2. Overlapping time segments are not allowed. For instance, if Quarter 1 is selected and the first time segment is set to 8:00 am - 10:00 am, then setting the second time window to 9:00 am - 11:00 am would be invalid. For different time modes, the time segment can be set to the same value. For instance, if one segment is set to 8:00 am - 10:00 am for Special Day 1, setting the time window to 8:00 am - 10:00 am for Special Day 2 would be valid.
3. Priority: Special Day 1 > Special Day 2 > Quarter (1 > 2 > 3 > 4) > Full year.
