Software updates - Master and ARM now the most recent versions after a previous posting, and assistance from folks here

Slave however is at 1.02

"If you have been using the Fox Agile integration" - I have not. Just the App recharge timer and Mode Scheduler setup that hadnt been changed in any way ...

My solar system has degenerated into a complete farce - six or more breaker trips a day, unreliable export which stops for no apparent reason and virtually zero alarms on the system. I am slowly concluding that either last software updates to the latest build are a complete POS, or I have major ...

It appears to be 2.004 ( Version_BMS) ?

EDIT - the system has been stable and woking for six months so while it could be software, it generally only becomes a software issue is something changes, and nothing has changed since installation ?

Software updates - Master and ARM now the most recent versions after (another)reboot.

Slave however is at 1.02 and battery is again offline !

I know its 'not there' as the animated graphic on the web portal has zero activity whereas usually it shows at least some power in or out, even if 0.001 kW

I cant help you with a solution, but I had it happen recently - in fact only a few days ago.

Battery over voltage
2025-04-26 08:52:59 BST+0100

Like you, a battery reset (I did the whole system) solved it. I am hoping to get the system software updated next week.

Thank you.

Two restarts and its now working.

I realised that on the first restart, I had not held the little silver button on the batteries long enough to kick the batteries back to life. As soon as I did that, the system started charging.

I will still progress with Fox getting the software ...

Thank you for the link to the video - the system was rebooted this morning and came back up, web portal showing usage but sadly, batteries still not being used.

I guess I will have to wait until Monday for Fox to do their thing

This is the error log due to the reboot.

Battery over voltage ...

Thank you

Minsoc is set at 10% and has been unaltered for months.

Charge period from the gris is 0200 to 0317 - no other time. Unaltered for months

You are correct - nothing has changed for a month or more.

Inverter is H1-5.0-E-G2. Its set up with 16 Fox ESS Panels and two 4.2kWh Fox batteries ...

I noticed on my App, and confirmed on the web portal that the batteries didnt charge overnight on the cheap Octopus tariff (I usually charge only between 0200 and 0315).

Looking at the usage today, I also noticed that this mornings usage is not being taken from the batteries - just direct from the ...

Our installer set up the forced export for us earlier in the month, but it seemed to result in us also importing far more than usual, so we turned it off again!

That suggests that you are exporting so much of your battery capacity, that there isnt enough left to run your household. Also, if you ...

I'm currenlty working with the installers to find out why they spec'd an inverter only capable of handling 72% of the PV panel max output.


My personal perspective is that where I live in the UK, the chances of getting the solar panels running at near 100% capacity for any length of time, is ...

Thank you - it returned to normal this morning.

My recharge time on Octopus is 0200 for an hour.

My discharge time is from 1600 until the battery hits its force discharge minimum.

The App confirms this - nothing has changed there.

The front panel of the inverter shows the time as 0807 so that appears to have changed

But I noticed this ...

I always see trickle grid usage even when batteries are full. I put it down to a combination of the accuracy of the systems not being 100% and that the smart meter itself runs off the grid and cannot pull from the battery.

Another question if I may - I have looked down all the graphical options you directed me to above, in the hope of finding the equivalent of the 'solar' button on the App, showing the PV generation curve but cant find it.

The portal shows the 'Todays Yield kw-h' number and the App shows the 'PV ...

Awesome - your knowledge is so very helpful to all of us !

Thank you - but not on my web page unfortunately

At the bottom of the page I have graphs of the the usual lines of Output Power, feed In Power, Load Power, Grid/Consumption Power, Charge Power and Discharge Power.

Theres no drop down menu anywhere on the page

I dont believe the batteries are 'on ...

Hi,

Is it possible to get the battery SoC state graph available on the web version of the portal ?

All I have is a an icon with its percentage state b ut not how it alters through time - which the App does quite well, but is too small to see the detail.

Mine died off this morning around 11.30, came back 45 minutes ago and has gone again - all zero'd out, on both App and web interface.

I checked on my phone and theres an App update awaiting so I set that going. No change after update so I guess its their back end thats the issue.

Okay, I am changed over to Octopus and had confirmation that I am on the Flux Import tariff and today they asked for the startup meter reading on the Export side which has duly been provided.

I've been online and confirmed that they now have me able to export and all their checks have passed.

The ...

Thank you again. I found the manual for the electric showers and they are indeed 9kW showers, which explains all.

i played around with some numbers and even doubling the battery storage wouldnt get to the 9kW and the constraunt appears to be the 40A inverter figure. I also looked at the data sheets ...

Thank you - a very concise answer - much appreciated.

So would it be your belief that the batteries are being used in the first instance and its the balance thats coming from the grid and showing up - or that unless you can get close to 100% from the battery/inverter, the grid will come first ?

I ...

Hi,

System installed a month ago and I have recently changed over the Octopus Pulse, so cheap rate charging is from 0200 to 0500.

Scheduler is set and the batteries are charging to full capacity at the end of the charging period.

I have;

16 panels producing 7kWp
