Random measures from SUN-12K #3

Closed AndihX closed 10 months ago

Hi,

We've just flashed a ESPHome on a ESP32, and used your configuration. It's initiated as it should, however, it's reporting very random-like numbers on each sensor.

We've followed the wirering diagram, and it's clear that it's OK.

After the ESP32 has been rebooted, we're back to normal numbers for a period of time.

Is this a timing or signal issue? Have you experinced simular problems? (We just tested with 20s interval)

Is is triggered by a specific event on the DEYE, or?

Here's a correct "load" with numbers:

We've tried to move the NodeMCU is moved outside of the "inverter-box", to secure proper WiFi-signal. That didn't help.

If we restart the ESP32 by using the "restart" command in ESPHome, nothing changes:

Restarting the ESP32 by unplugging and replugging the USB-cord, nothing changes:

Replugging the power to the RS485>TTL module board, things works fine again.

This time it worked for appx. 10 minutes, and ended up like this:

Note the "standby" signal. I'm not sure if that just a faulty read, or if it's actually a proper state returned by the MODBUS-interface from the DEYE?

Hereafter it worked just fine for more than 20 minutes, and now we're giving us a break from the DEYE-fight :)

Let us know if you have any inputs.

Ka' du ha det godt så længe ;) :D

The standby is a valid Running Status, when you dont have a battery installed, and the sun is down. Mine does the same: image

keldbroe commented 1 year ago

I've got the same problem. Have you solved it, or do you still have the issue?

AndihX commented 1 year ago

No solution yet, though i am glad that i am not the only one. What i have figured out, is that it is the 12 to 5v board that is some how not stable. My temporarily solution was to use a 12 to 5V usb charger for a Mobile phone. It does not look nice, but it helps for now. I have tested 3 12 to 5v boards so far, without sucess.

Strange thing. I've tried to replace the PSU to a normal 230V-USB adaptor, and it seems to fix the problem. I've noticed that, when I have the problems the TTL/RS-485 board is VERY hot. So hot so I can burn my finger. When it worked the temperature was not noticeable. Could you try that? Or as a minimum try to touch the TTL/RS-485 board briefly.

I have mixed results: Im using a ESP32-Wroom in a D1-mini board, works fine on 3 installations. Now I replaced 1 in the Deye inverter to a ESP32U-Wroom (U for external antenna) this made the TTL board run hot instantly, running on the same internal power and a buck converter to 12->5V. Now I tried an external 230V-5V USB charger, and temperatue is down again.

klatremis commented 10 months ago

I have reports on that there is different models of the TTL/RS-485 boards. Even that they look like the same, they act different. Some people have reportet that the boards from one supplier died after a few days. I think its all about the component quality.

My suggestion is:
