The above codes seem no longer valid. I’m interested to evaluate the 100A model.

Kind regards,

February 14, 2022,KG series APP “firmware upgrade” is moved to “after-sale”,
Enter the after-sale code “8610” to enter the firmware upgrade,
Then enter the default firmware upgrade code “000”,
Please exit the firmware upgrade function after seeing the prompt that the firmware upgrade is successful;
Otherwise, the product will not work properly;It can work normally only after a successful firmware upgrade is completed again.

At present, there is no new firmware update for the product,
The firmware is expected to be updated on February 28,
Will increase the conversion between Fahrenheit and Celsius,
Increase full power voltage & extended function of full power current
Add extended function of power loss voltage
Coming soon.

The code doesn’t apply to the 100A meter in the first link

I am trying to remember an old tv commercial which went something like “With a name like something_or_other we have to be good!”. I think that applies here.

Smuckers

Yeah, naming your company JUNCTEK does not inspire confidence.

Reverse Psychology!

I’d like to purchase one of these units. Can you please apply a new discount code please.
Thanks

Regarding the April 10 firmware update:

On April 10, 2022, we upgraded the mobile APP and product firmware, Android and Apple mobile phone systems have been upgraded;

update content:
1、Low -capacity reminder has been added to the mobile APP ;
2、Low temperature protection has been added to the mobile APP (relays are required for this function);
3、The temperature can be switched to display Fahrenheit or Celsius;
4、The accumulated power (kW.h) only calculates the power consumed during charging;
5、Cumulative capacity (Ah) only calculates the capacity released during discharge;
6、The scale range of the voltage and current instrument panel in the mobile phone APP can be set freely, and the scale value of the voltage and current curve also changes accordingly;
7、Four extended functions have been added to the mobile APP:
Full voltage, Empty voltage,Tail current, Charged detection time;
For example, 12V 400Ah lead-acid battery, set the full charge voltage to 14.4V, Set Tail current to 2%, which means that the full charge current is 400*0.02=8A, and the Charged detection time is set to 2 minutes, which means that during the charging process, when the voltage is higher than 14.4V, the Tail current is lower than 8A, and after the duration exceeds 2 minutes, the percentage of remaining capacity will be automatically adjusted to 100%;
Set the Empty voltage to 10.5V , which means that when the voltage is lower than 10.5V and the duration exceeds 2 minutes during the discharge process, the percentage of remaining capacity will be automatically adjusted to 0% (if you feel that the Empty voltage is not very practical, you can set the full voltage, Tail current, and Charged detection time without setting the Empty voltage.)

Update method:
1、First update the mobile APP
1.1 Uninstall the original mobile APP first;
1.2 iPhone Search “KG series” in Apple Store”,
1.3 Android phones can download through this link
(http://68.168.132.244/app/KG.apk), Or use the mobile browser to scan the QR code in the measurement module to get the APP;

2、After opening the mobile APP, See the following demonstration pictures to operate the connection。

3、Find the “Settings” - “After-sales Service” function and enter 8610 to see “Firmware Upgrade”, enter the firmware code 000 and wait for the firmware upgrade to complete before exiting。
Why is the firmware upgrade function not intuitive? This is because some customers have mistakenly operated the firmware upgrade and then exited before the firmware upgrade was completed, which would lead to product failure, so we recommend that you must complete the firmware upgrade before exiting.

Special reminder:
If you place an order before January 1, 2022, you need to power off the product before clicking the firmware upgrade, and then power on the product while short-circuiting the temperature measurement interface, and then follow steps 2 and 2. Step 3 Perform firmware upgrade.

4,After seeing the prompt that the firmware upgrade is successful, exit the mobile APP and then reopen the mobile APP. Follow step 2 to connect successfully and you can use the newly added functions.

Thank you for your reply. We want to make better products!

Kg140f has made a quick installation video to help you quickly and correctly install this device


This week, I received the newly purchased kg140f.
I found that their monitor shell has been painted,
Just like the car paint. It looks metallic,
much better than the previous one.

We have launched a new version
No display required
You can view data only through the mobile app.

As for this product, do you have any ideas for improvement? I contacted their engineers and said that they were designing the second generation KG140F recently

I’ve just bought one of these, the KG110F and like it so far.

Really there is only one thing so far that would improve it for me, and that is being able to set a current threshold for the display standby.

As it is, it will only turn of the display after time set if the current draw is 0A. I have a solar charge controller connected that draws 0.02A in standby which means the display will never turn off even though I don’t really need it.

It would be great if I could set the minimum current draw needed to keep the screen on so I could ignore standby currents for the display but still keep track of them (this is the first meter I’ve had with enough precision to even show the charge controller standby current)

(Oh and a side entry for the displays cable port probably would have been better than the rear one)

I have a five battery system in my boat.

1 house, 1 starter and 3 x 12v for trolling motor. I would love this, but 5 screens and $250 is too much.

If the app could be used for 5 units I would buy the no display version
