HELP: code: 41811 user permissions do not allow this operation

[shmzhu]

Hi guys,
I am currently using the up-to-date FoxCloud 2.0 app. Up until this morning, when I tried to change the Quick Settings under "Export Limit" & "Import Limit:, I suddenly encountered the below error message:
code: 41811 user permissions do not allow this operation

Given that error my system's current battery export is capped at 5kwh... even the value in the scheduler is above this figure.

I always use the same account to login and nothing has change but suddenly lost ability to manage my devices... I have submitted a support ticket through Fox's official website. In the meanwhile, has anyone got a solution to this?

Fox ESS has been making lots of server changes + forcing firmware upgrades on inverters/batteries.

Thank you, I have received firmware update for the data dongle today and not sure if that's correlated. Since v2.2.0+ the features are very unstable and prone to errors.

The problem is the app doesn't check to see if it can do something until you try to save and then you get opaque error messages that just leave people confused.

So it's more about usability issues than actual bugs in the typical sense.

I noticed the similar issue since morning! have also created a support ticket.

I managed to find a workaround by using a third party app called Energy Stats and regained the access to all previous settings from there. Hope it helps!

It is good you found a work around via 3rd party app.

For anyone else following, End User access accounts are blocked from making changes to certain values, hence the message seen.

But why "Quick Settings" => Import & Export Limits, that was very much needed functionality. That was so handy and now I am stuck the way I used to use was set a scheduler to max values and limit it quickly from Quick Settings so no messy thing. But now I am stuck cos previously I set my Import Limit to ZERO now, when I even do the force charging with Allowing Grid Import it is not importing anything from Grid cos my Import Value in Quick setting was ZERO.

Why this was important in another situation as well is, because my retailer charges negative FIT during some hours, and I have my self-mode ON, but then when my battery gets fully charged it start sending it to grid which or I want to limit my export during a schedule I used to use that for quick change rather than going into scheduler.

Why would you stop that??? That's an important feature for an end user.

That's due to schedules being set, not end users not allowed to do something.

Yes this is a problem... i only want to export 10,000w over two hours, i set my discharge to 10000w per hour for two hours, with the limit at 5000w export in quick settings. This way my house doesnt eat into my 5000w export.

now the feature is disabled... what if i wanted to export more, i cant be asking support every time i need to do it when that functionality was available before.

Do you have at least 1 schedule set, even if it's disabled?

Funnily enough, all my schedules were removed when I woke up this morning and I was in self use mode instead of advanced schedule, I had to re create them all.

In that case you can only set limits in the schedules themselves. Otherwise you get the above errors.

Not sure we are on the same page.
The force discharge schedule only allows 3 configurations.

Time start/end
Discharge Soc cutoff
Force discharge power.

Force discharge power is the maximum output I can send out of the battery, if I intend to do 5000w per hour and the house takes 3000,it will eat into my export if I only set it at 5000w.

This is why export limit is used.

The problem is at the moment when minSoC (Discharge Soc) is hit in a schedule at the moment the battery doesn't switch to self use and the house will start importing power at the wrong time.

In schedules the global min/max SoC settings are ignored.

There is a couple of ways around that, the first is to estimate how long it will take to hit minSoC and set the start/end time accordingly.

Others say the Energy Stats app can handle this limitation for you.

It's hard to estimate, the export is between 6pm-8pm. Dinner time could have an oven on, EV could be charging.. whatever the case. The original function worked fine. .

Would you be on Globird by any chance?

If so I've been working on a python script to guesstimate usage, download forecasts and so on and then spit out what it thinks would be worth importing between 11am and 2pm and what the excess might be for between 6pm and 9pm, as we still get 6c between 4pm and 9pm.

The script is also able to upload the schedule it thinks would be most optimal too.

As we only have a 5kW inverter, we can't do more than about 8kWhrs between 6pm and 8pm anyway, but I did code it to handle that for those that can.

If you export more energy than the grid can support, then you break the sub-stations.

So these limits are input into your Inverter to stop this from happening, and the End User level accounts never should have been able to change these values, only the installers.

There seems to be some confusion about the Export limit and how this affects your output.
Strictly speaking you are asking your Inverter to convert enough DC to make xxxx Watts of power.

Example, if you ask for 5000W, it will use say 5200W of DC power as energy is lost in conversion and the Inverter itself uses power.


Now if you read my post above regarding why export limit are needed, then you understand hopefully that we cannot as End Users input what we like, you will eventually fry a Sub-station if not careful.


As for your export limit, if this is 5000W and coded into the Inverter, you could set a schedule for discharge at 10000W (if you Inverter goes this high) and it will export 5000W, and make upto 5000W if the house needs it.

Example, you set 10000W, you have 5000W going to the grid via your export value, leaving 5000W. If you house needs 1000W, then the system will make 6000W in total, no more.

Fry a substation... I'm not a huge power plant, if you think homes are generating and exporting MW's of power each then that could be a possibility. Even then there is a cap based on your inverter capacity and the app itself restricts to 60kW.

My inverter is 15kWh with 42kW of battery storage.

I am not confused about how these settings work.
What if I want to set 10kW export, 15kW export?

If I set my inverter to 15kWh discharge, I am still export limited by 5kWh based on the locked limitation no matter what discharge schedule I set. There are windows for wholesale energy suppliers who will buy feed in during grid instability and they are short windows that can net almost $20 per kWh exported within 5 minutes.

Before this app update I could update it as I required.

I will bow out of this thread, I guess the grid limits don't apply in Australia

It depends. I've only looked into my own distributor and the current limit is 5kW for single phase, it used to be 10kW.

The current limit was introduced to try and limit solar exports during the day because the various government rebates were too successful in driving adoption.

This is so much of a problem all states have, or are in the process of legislating a backstop mechanism in the very dire event that all else has failed to keep the grid balanced so they'll be able to broadcast a signal to stop exports from inverters.

The hard limit throws a spanner in the works with battery systems because the same limit also applies in the evenings when the grid could do with more power being exported from distributed systems.

So come July along side the backstop mechanism they're also going to introduce dynamic export limits for internet connected inverters if there is spare capacity in the grid.

Unfortunately the PDF is very light on details.

The problem isn't the frying, they've all been upgraded as far as I know, the problem is when too many people export too much all on the same phase and it leads to grid imbalances between phases.

https://www.theelectricalguy.in/power_s ... ase-loads/

Not sure where you are but the local grid here is only rated at 100A or ~24,000W per phase.

I am still export limited by 5kWh based on the locked limitation no matter what discharge schedule I set.

They aren't as locked down as you assume them to be, pretty sure that's what the comment was about.
