Commissioning
6.1 Commissioning of JKS
Electrify JKS after all installation of Part5 be finished, here are the steps:
1.Connect PV
2.Connect AC
3.Connect battery
4.Turn on AC first
5.Then turn on battery
6.Last turn on PV
The first installation will prompt you to select areas A,B,C
.
And the power quality
response mode is changed by PQRM setting.You can refer to part 6.5.5 on page 51.
If PV Grid and battery are available, system would work on the “normal” mode. When
JKS works normally, the screen displays "normal" and the LED is green. If JKS not enter
normal mode successful, especially the LCD is red, you need to check below:
1.Make sure all the connection is correct.
2.All the external switches are on.
3.Inverter built -in switch is on.
4.Make sure the lithium battery is on.
5.Refer to Part 9.1 for correction.
You can refer to Part 6.3.4 for work mode setting, then configure monitor, finish
commissioning lastly.
6.2
Operation Modes
6.2.1
Normal Mode
Normal mode is working state which including online mode and backup mode.
Online mode
User can set an appropriate priority mode according to request when JKS working on the
online mode. If customer uses the LCD and key settings, you can only set one period, but
if you use website settings, you can set up to three periods of the priority mode.
(refer to 6.3.4)
1. Load first: Load first is the default mode, when it's working in this mode, PV energy
would offer to load and battery prior; when PV is Insufficient, battery would discharge;
when PV is sufficient for load, the excess energy would feed to battery. If there is no
battery or battery is full, the excess energy would feed to Grid (If the export limit
function is enabled, the excess PV energy will not be sent to the power grid).
2. Battery first: When JKS working in this mode, battery would be charged first, it's
suitable working on the period when the electric charge is low. user need to set the mode
ON and OFF time, and the end time of battery SOC. Users can set power rate which less
than the battery maximum output power. If the customer doesn't enable the AC CHG
(AC grid charging functions). Inverter will charge battery by PV power as large as it can
do. If the customer enables the AC CHG (AC grid charging functions). Inverter will
charge battery by PV power and AC power from grid as large as it can do.
3. Grid first: When JKS working in Grid-first mode, the PV energy would feed to Grid
first. User can choose the period when electric charge is high. User need to set the mode
ON and OFF time, and the end time of battery SOC. User can set power rate which less
than the battery maximum output power.
Backup mode
If Grid is lost, system would switch to backup mode (user can disable this function, refer
to 6.3.4) and AC output is supplied via the EPS LOAD port using energy from PV and
battery. If the PV is also lost, then only the battery discharges.
Note: JKS EPS LOAD maximum output power is 4000W so loads connected to the EPS
LOAD port should not exceed 4000W.
Notice:
1.Users only can set one period for battery first and Grid first on the LCD, if users need
set more pleases login shineserver.
2.If users need Grid charge battery, users need input password on the SC surface and set
the AC CHG to enable.
6.2.2 Fault Mode
The JKS's intelligent control system could monitor and adjustment system's status
continuously, when JKS inverter monitoring anything unexpected happen, such as
system fault or machine fault ,the LCD will display the fault information, in fault mode,
the LED light will be lighten.
Notice:
1.The detail's fault information please refer to 9.1
2.Some fault information is in order to remind users that might have some faults
occurred in inverter side.
6.2.3 Programming Mode
Programming mode indicates the JKS is updating, don't cut out power when it's
updating until the processing is finish, JKS inverter would log out automatically when the
updating finish and turn to other mode.
6.2.4 Checking Mode
Before JKS work in normal mode, it will go to self-check mode. If all are ok, system will go
to normal mode, otherwise, it will go to fault mode.
6.2.5 Standby Mode
If the system hasn't faults while the condition is not qualified, JKS would stay at standby
mode.
6.2.6 Shutdown Mode
If customer need JKS inverter stop working, customer must disconnect all the energy
source, then JKS inverter will turn into shutdown mode automatically.
The following is the shutdown procedure:
1.Shutdown the PV side
2.Turn off battery switch.
3.Shut down AC power of JKS. Then you can see the both LED and LCD of SP are off.
Notice:
After all the actions are done, you still have to wait for more than 5 minutes.
