Start-up and Shut Down JKS system
7.1
Start-Up The JKS system
Users can start-up JKS inverters through following steps:
1.Connect to PV.
2.Connect to Grid.
3.Connect to Battery.
4.Turn the switch on in turn of Grid, battery and PV.
5.When the LED turns green, the working information on LCD indicates the successful
start-up of JKS inverter.
7.2 Disconnect The JKS System
1.Turn off all the circuit breaker and switch
2.Disconnect PV
3.Disconnect the inverter
4.Disconnect the battery
5.Pull up AC PLUG connection
6.Waiting until LED, LCD display have gone out, the JKS is shut down completely
7.3 Export limitation and Power Sensor Setting
Chart 7.1
Under the permission given by your energy provider, the ratio of your system output
power divided by the rated power of the inverter is called Export Limit Rate. For instance,
if the energy provider only accepts 4kW from your 5kW system, then the Export Limit
Rate of 5kW inverter is 80.0%.
Heat dissipation performance is very important when JKS inverter work under the
environment of high temperature, better heat dissipation can reduce the possibility of
JKS inverter stops working. JKS-3~6HLVS-ABI series inverter without fan so belongs to
natural cooling, hot air from the top of the radiator, tie-in battery, use environment for
IP65, please pay attention to the temperature of the installation environment, to ensure
that the battery's safety and the normal work of the machine.
When use battery, please pay attention to the follow information:
Caution: Do not dispose of batteries in a fire. The batteries may explode.
Caution: Do not open or damage batteries. Released electrolyte is harmful to the skin
and eyes. It may be toxic.
Caution: A battery can present a risk of electrical shock and high short-circuit current.
The following precautions should be observed when working on batteries:
l
Remove watches, rings or other metal objects.
l
Use tools with insulated handles.
l
Wear rubber gloves and boots.
l
Do not lay tools or metal parts on top of batteries.
l
Disconnect charging source prior to connecting or disconnecting battery terminals.
l
Determine if battery is inadvertently grounded. If inadvertently grounded, remove
source from ground. Contact with any part of a grounded battery can result in electrical
shock. The likelihood of such shock can be reduced if such grounds are removed during
installation and maintenance (applicable to equipment and remote battery supplies not
having a grounded supply circuit).
If JKS inverter doesn't work for overheating or too cold, solve it according to the
following methods.
l
Confirm whether the radiator air duct installation be reasonable, choose the
appropriate position before installation.
l
If lead-acid batteries are connected, confirming the NTC battery is in a good
installation.
l
Confirm whether the battery temperature is too high, too high temperature of
battery can also lead to JKS fail to work, at this point, to ventilation, cooling or still
handle to the battery, please.
l
If temperature is low, also can appear the battery low temperature protection, the
battery will start with small load in low temperature output, after temperature back to
normal system can work normally, please be patient at this time.
l
If the temperature is too low, it is possible that battery will be low temperature
protection, at this time, please pay attention to the working temperature range listed in
the specifications of the book.
l
Servicing of batteries should be performed or supervised by personnel
knowledgeable about batteries and the required precautions.
l
When replacing batteries, replace with the same type and number of batteries or
battery packs.
l
General instructions regarding removal and installation of batteries.
In order to protect the safety of the operation of the system, the inverter needs to be
regularly maintained and cleaned as follows.
l
Check whether the grounding wire is loose.
l
Whether the terminals are loose.
l
Keep the metal housing of the inverter clean.
