Charge Controlles Go to Silent

Post by omarbur » Sun May 10, 2020 2:08 pm

Hello expert;
I have a strange situation in my system, below description of system:

My system is GRID-TIE:

Kyocera:
- 9 solar panel 265W Model KU265-6MCA (2,385 watts hr)

Solarworld:
- 6 Solar panel 300W Model SWA 300 MONO (1,800 watts hr)

Solarworld:
- 9 Solar panel 285W Model SWA 285 MONO (2,565 watts hr)


Midnite:
- 1 Combiner Box MNPV12

Outback:
- 3 Charge Controller FLEXmax 80
- 2 grid-tied Inverter VFXR3524A for 120 VAC
- 1 flexware 500
- 1 Mate3s
- 1 Hub10.3
- 1 FNDC
- 1 RTS
- OpticsRE

Rolls:
- 4 6V Battery 6CS 25P x 820AH


The issue is the following:
At any time during the day the charge controllers (FM-80) go to the silent state.
If the communication cable are remove from charge controller the system work fine (Bulk).

This issue is happen from 5 days ago, and no change in parameter.

Please Colleagues give me your feedback. Thanks

Starting with a side note: The three PV arrays feed each of the three FM80s independently, correct?

What is the combine box doing? Servicing one array/charge controller?

Do all three charge controllers go silent at the same time?

What is the charge controllers' displayed status when they stop charging?

One speculation is an external charge termination command. The Mate is capable of issuing such a command if configured to do so. It would get its cue from the Charged Parameters Met setting on the FNDC.

Another possibility is the grid is providing charging power via the Inverter chargers and the settings are such that those chargers have priority over the charge controllers.

Neither case would be reset by removing the charge controllers' communication cable, AFIK.

Is there anything in the event log that gives a hint?

Thanks in advance for your time.
Below my answer:

Starting with a side note: The three PV arrays feed each of the three FM80s independently, correct?
Yes, is independently

What is the combine box doing? Servicing one array/charge controller?

** Each CC have a separate Bar bus (Positive) in the combiner BOX

Do all three charge controllers go silent at the same time?

** Yes, at the same time

What is the charge controllers' displayed status when they stop charging?

** First the status can be Bulk or GT, the all of then go to silent

One speculation is an external charge termination command. The Mate is capable of issuing such a command if configured to do so. It would get its cue from the Charged Parameters Met setting on the FNDC.

** No external charge is in place.

Another possibility is the grid is providing charging power via the Inverter chargers and the settings are such that those chargers have priority over the charge controllers.

** The changer is turn off in both inverters, only the CCs can charge the system, it is rare that I see a charging status in the the second inverter (That is Charger turn off)

Neither case would be reset by removing the charge controllers' communication cable, AFIK.

** I do multiple time, also upgrade the mate3, but the same.

Is there anything in the event log that gives a hint?

** No, no log related to the issue

I have an off-grid system, so may be mistaken, but the Inverter screen shown from the Mate appears to be drawing (a small amount of power) from the grid, and the upper left corner indicates "Charging".

Two things to check - either on the Mate or in Optics RE:

• Mode of the inverter charger - it should be "Off"
Screenshot_20200510-140417_Chrome.jpg
• That the Absorb and Float set points for all three FM80s are the same, and that the Absorb and Float set points for the Inverter chargers are 0.2V lower than those on the FM80s.

Yes; is in that way.

1. Both Inverter charger are off (Confirmed), attached

Inverters:

Absorb Voltage = 29.4v
Float = 26.8V

CC:

Absorb Voltage = 29.6v
Float = 27.2V

Man, I don;t know what is happen. I reviewed all.

Yes, it is very strange.

It was mentoned that unplugging the charge controllers from the Hub caused them to restart charging, is that correct?

If that's the case, perhaps let them run for a day disconnected from the Hub. The FM80s are perfectly capable of running autonomously. The FNDC will still track the charging current (though won't attribute it to the disconnected charge controllers). OpticsRE won't show the FM80s but will still show an undefined charging source.

At any rate the idea is to see if the FM80s complete a full charge cycle without going silent before sundown, and in that way, eliminate them as the source of the problem.

I did that; today after 9:00 I disconnect the 3 CCs, they charge normal. for me that prove that the issue is not CCs

Perhaps the next test would be to charge the batteries to about 80% using the FM80s, (disconnecting them from the hub if necessary), then connect the charge controllers to the hub, and disconnect the inverters from the grid. With CCs connected to the Hub and Inverters disconnected from the grid, see if the charge cycle completes normally.

So you have 1 inverter in Port 1, another inverter in Port 7?. Not sure if this has an effect. Why not Ports 1 & 2?
Please list what components are in which ports

I have observed this behavior if my batteries are charged, there is load being supplied such that battery voltage is below that of sell voltage and also grid voltage out of range like 250 volts. I think you can try setting charge controllers to also restart timers. I also would try increasing absorb timers to like 4 hours if you are selling.

David, Omarbur - From firsthand experience, I know that this will not affect proper operation. My FX's are in ports 1 & 7 also. They were originally in ports 1 & 2 but there was some problem with port 2, not sure if it was the cabling or the Hub, but in any case the problem went away when I moved the slave inverter hub connection to port 7 with a different cable. Operation this way has been normal.

I wondered about port assignments as well. Here's some snippets from the VFXR manual:

The arrangement if stacking the inverters for two 120V legs - 180° out of phase:
Screenshot_20200511-061809_Drive.jpg
The arrangement if stacking the inverters for 120V master/slave
Screenshot_20200511-061809_Drive.jpg
The first configuration requires master in port 1 and sub-phase master in port 7.

The second configuration requires Master in port 1 and slave in any port 2 and above.

Both configurations can be assigned ports 1 and 7.

Thanks, guys, you were busy as I slept.
Hadn’t seen that diagram Ray, a bit different than the Hub manual itself. Guessing this is a FXR thing? Mine have been all inverters before the CC, but that was FXs

Re: Charge Controlles Go to Silent

Guys;
I have in that way Master (Port 1) & Slave (Port 7)

Today I received a recommendation from Outback:

"Try taking the charge controllers out of Grid-Tie mode. The setting in the FM80s, not the inverter. In OpticsRE go each to FM80 Device Map in the Misc tab, Grid-Tie Mode and change to Disable. If this fixes the problem it's probably because the inverter is getting too hot and is asking the FM80s to scale back their output, which in turn should cause the inverter to cool down because it is selling back less power. However, in some cases it causes the FM80s to shut down too much. If the inverter starts to overheat, and may even shut down, you may have to find a cooler location for the inverter or switch back to Grid-Tie Mode enable"

I do that and now is working (selling). I don't know if really is the issue, below the curren temperature value

Inv1:

Transformer Temperature: 186.8 F
Capacitor Temperature: 145.4 F
Output FET Temperature: 161.6 F

Inv2:

Transformer Temperature 197.6 F
Capacitor Temperature 143.6 F
Output FET Temperature 149 F

Or this values are normal?
The Inverter have enable: Cool Fan on

I'm in the caribbean, so is very hot, but never happen. I have my system from 2017
I don't know.

Thanks, guys, you were busy as I slept.
Hadn’t seen that diagram Ray, a bit different than the Hub manual itself. Guessing this is a FXR thing? Mine have been all inverters before the CC, but that was FXs
I'm just a country bumpkin with a single FX3048T off-grid, so all this grid-tie, stacking, split-phase stuff is way over my head. I'm forced to RTFM to stay in the conversation. The pages I posted were from the FM for the FXR inverters.

Guys;
I have in that way Master (Port 1) & Slave (Port 7)

Today I received a recommendation from Outback:

"Try taking the charge controllers out of Grid-Tie mode. The setting in the FM80s, not the inverter. In OpticsRE go each to FM80 Device Map in the Misc tab, Grid-Tie Mode and change to Disable. If this fixes the problem it's probably because the inverter is getting too hot and is asking the FM80s to scale back their output, which in turn should cause the inverter to cool down because it is selling back less power. However, in some cases it causes the FM80s to shut down too much. If the inverter starts to overheat, and may even shut down, you may have to find a cooler location for the inverter or switch back to Grid-Tie Mode enable"

I do that and now is working (selling). I don't know if really is the issue, below the curren temperature value

Inv1:

Transformer Temperature: 186.8 F
Capacitor Temperature: 145.4 F
Output FET Temperature: 161.6 F

Inv2:

Transformer Temperature 197.6 F
Capacitor Temperature 143.6 F
Output FET Temperature 149 F

Or this values are normal?
The Inverter have enable: Cool Fan on

I'm in the caribbean, so is very hot, but never happen. I have my system from 2017
I don't know.

I don't see a temperature derating curve for the VFXR series inverters, but the (sealed) FXR series creates up to 140°F, and is not rated for operation above that temperature. I'm guessing the vented units could go 25% higher, but that's only a guess on my part. In any event, the elevated temperatures are not improving performance in any way.

Perhaps Outback can provide temperature specs for the VFXR series.

Is the equipment room ventilated? Maybe a large fan yo blow entrained heat away from the equipment would be helpful.

LOL, yea I try to avoid looking stupid by getting involved with grid tied, some times I fail.
Not having FXR’s I just looked at the HUB manual.
Time to crawl back into my covid hole :lol:

The high temp posting sounds sounds plausible. Good luck.

Thanks you guys;
Yes I have window, but still a Littler hot. is the Caribbean.
I will continue monitoring and try to do a workaround, may be an additional fan.

Thanks Omar. Just letting you know that even our software VP David Lebow will ask you for your system name to be included in your profile. Even if it is up there, unless you give them a Read access, the general Forum community can't see your system in Optics. I can see your system, but there is no way that I have the power to change your settings. I don't want that access.

Now, to your system, I am not sure why the inverter in port 7 was charging even if the charger was set to off. And it is night time there now, so the CC's are normally silent. What you can do to totally prevent charging is set the charging current to 0 A, in addition to charger off.
Or turn off the inverter on port 7, and observe. See what happens.
