Update for today;

1. Yesterday after remove CCs from GRID-TIE mode everything work fine

2. today I put back the CC3 in GRID-TIE mode and immediately the CC3 go sleep, now I not sure that t the issue temperature , the time is 9:20 AM, below temp:

Inv1:

Transformer Temperature 122 F
Capacitor Temperature 107.6 F
Output FET Temperature 123.8 F

Inv2:

Transformer Temperature 131 F
Capacitor Temperature 113 F
Output FET Temperature 127.4 F


May be other issue.

Can I take a capture of the messages? like networking

CCS status are attached and the inverter in Port 7 that selling (wrong)

Hello Greg;
have we any way to capture the messages in the system?
Just to see what is the trigger for issue. like wireshark for Networking, where you can capture the packet and analyze.

Hi Orlando,
Relevant event messages are captured in the Event History tab. There is also a version of them messages in the MATE3s by pressing the "Events" button.


As for the viewing of packets, you can probably use wireshark. I seldom use it, so I can't offer insights on what you will see.

Just connect my laptop to Hub?

Or you have a procedure?

I would like to do that.

What do you thing abaout issue, witout Hight Temperature?

YIKES! DO NOT connect a laptop to the hub via Ethernet. While both networks use RJ45 ports, the Hub is not Ethernet protocol and is electrically incompatible.

Wireshark is not the tool you're looking for.

There is a no longer supported, but potentially useful application: WATTPLOT, that may be helpful. You might want to check out Wattplot.com.

Try this one ----> Re-enable Grid-Tied mode in the CCs, but DISABLE Auto Grid-Tie Control in the Global Charge tab of MATE3s.

Hello Greag and community;
Just an update.

1. I Have the same issue (CCs go to silent when is in GRID-TIE)

2. Greg, I do the change that recommend, (Re-enable Grid-Tied mode in the CCs, but DISABLE Auto Grid-Tie Control in the Global Charge tab of MATE3s., but the same behavior.

3. Yesterday I change the software for inverter from 001.006.067 (Puerto Rico only) to 001.006.063, just for validate if not a software issue.

4. Also the Inverter #2 (Port 7), continues erratically behavior, some time is showing Status: Buying, but or Charging, this time Buying, but we have solar production. also the inverter charger is turn off

5. In order to validate that the temperature is not the problem, I do some change in the system, below details:
a. FlexNet: Charged Voltage from 29.4 to 28.8
b.

7. I change the "Sell Current limit" for 15A to 28A, but I notice that when I do that the Inverter #2 (port 7) lost phase, I don't now why. but happen multiple times.

6. I try to use the WATTPLOT with cross cable direct to my PC, but Two issues:
a. The configuration in Mates3 for Data Stream (UDP/IP) can not be saved, if you reboot the the mate go back to default configuration, the procedure say that reboot the mate.
b. The connection to my PC is not happen, I use the same subnet: Mate3s 192.168.0.64/24 , PC 192.168.0.23/24

Mate3s Configuration:

Serial Data Stream Disabled
Serial Baud Rate 19200
Network Data Stream Enabled
Destination IP 192.168.000.023
Destination Port 57027

WATTPLOT:
Destination IP 192.168.000.064

I remark, that my system is working fine from 2017. just in March was adde the CC3.
For me is important have the exactly message that come to CCs, but WATTPLOT is not working a least for UDP/IP

Thanks

You might want to try Wattplot using the MODBUS interface.

I also try to Modbus/TCP, but not working

Greg, is it possible that OutBack review my system complete?

Just taking a stab at this after reading thread.
As I understand it, your charge controllers go silent with available PV and you are in grid tied sell mode. Batteries are charged.
As I reviewed the thread, everywhere I see 120 volt connection to grid and output from inverters.
I have not seen any photos showing the SOC of the batteries and their measured voltages for a string and each battery at it's terminals along with the load being supplied when the charge controllers are in silent mode. This helps to determine what is happening with the system. I have not seen any photos or comments on if the system is selling back to the grid. Does it sell or does it not sell to the grid? The grid interface protection menu may need to be set up to allow selling back to the grid. If selling back to the grid is blocked and the batteries are full and the load being supplied, the charge controllers have no place to send any PV. They sleep or go silent. You could also set the auto restart of the charge controllers to the 90 minute mode and see if that changes performance. Just some free thoughts that cost nothing and may be worth nothing.

Yes, the CCs are going to sleep when I have a lot power in PV. anyway the PV capacity around 6K, the house consumption is around 300whr. when is normar I selling all the day.

Battery are charged attached photo

The AC connection to GRID look ok

Attached photo of Inv1 Selling

I will set the " auto restart", I will let you know . thanks

Too bad Wattplot wouldn't configure. It's a useful tool but not one to spend a lot of time trying to get working.

One more random observation to throw onto the pile.

Are the inverters series-stacked to deliver 7kW @ 120V? If so, for testing purposes, can the slave be disabled for 24 hours to see how the system behaves without it?

Guys;
At the end, I just do a factory reset to both inverter, now the CCs look ok (GT mode), let see tomorrow how continue.

Hello Community;
I'm glad to inform, that after the factory reset to both inverter. the issue with the CCs was fixed.
Thanks a lot for all contribution.
That's great news!

Hello every one;
Again we have the issue. I have continued the review. I found a technical note from Outback:

fm_gt_mode_app_note: http://www.outbackpower.com/downloads/d ... p_note.pdf

I notice that my system have the two conditions described :

GT Number
While the primary function of GT mode is to keep the charge controller in Absorb operation, it can also maintain some control of the system to ensure that the system keeps selling. Two conditions that could prevent the inverter/s from selling are:


1. Rising inverter temperature due to high ambient temperature
2. Rising AC voltage due to high grid impedance.

as you can see in the attached picture:

My observation today. today no AC input high voltage, but high temperature:

I observed that the CCs start the countdown for GT number from 74 to 0 (I think that is received from Inverter), when is 0 the CCs go to sleep.

* I don't know what is exactly issue, hera my questions:

1. Inverter High temperature only for hot climate?
2. Inverter High temperature for quantity of energy sent to GRID (Sell)? i have around 6K in the PV array
3. Inverter High temperature for combination of 1 & 2?
4. High AC Input voltage?, today I don't see. or other parameter that is not see in the log as harmonic, can affect?

* I taked two actions:
1. I put a pedestal fan close to Inverters, trying to reduce the temperature
2. Reduce the "Maximum Sell Current" from 28 to 15 Amp, trying to avoid the hot temperature.

But do not work, at the end I put the CCs on GRID-TIE "Disable" for continue as normal

A least now is clear that Inverters are instructing to CCs that go to sleep.

The thing is how to avoid that:

I was thinking install a "The Turbo Kit Fan"
https://www.manualsdir.com/manuals/2068 ... ml?page=17

But in the documentation I see that is not for VFX inverter: "Do not use the Turbo with a vented VFX, It will actually reduce the output power of the VFX"

please give me the feedback. thanks

I have an off-grid system so do not have direct experience with grid tie, however, while the Inverter internal temperatures are high enough to cause derating (1% for every 1°C above 25°C,

the temperatures are not high enough to trigger equipment warnings.

Grid tie warnings merit some further investigation.

Folks, pedestal fans will not cool your system. You can try blowing air into and out of a cooler filled with ice (construct this using 4" dryer vent ducts with powered duct fans outputting from the cooler (low power consumption) into the intake vents of an inverter, you can try building a Peltier plate based cooling system, but the parts usually fail pretty quickly and lastly a small AC unit on the order of 4,000 BTU. This will do the job nicely, but the cost will be about 4 amps x 120 volts in USA.

Thanks PSS.

What about turbokit, Fan:

What do you think?
