One last precisation: Timing of the operation of the island mode isolator and N-E bond relay should comply with Regulations 431.3 and 537.1.5 of BS 7671. This requires: The N-E bond relay to be interlocked, or mechanically linked , with the island mode isolator , [...] This means that the potential...

I think you have summarised the failure modes very well (what do you do for a living, are you HAZOP trained by chance ?), and there are methods for you to alert yourself to floating neutral/earth, interlocks or to detect the earth fault and force a bond directly to the earth rod, but with complexity...

You can't appreciate how thankful I am for your answer. I just spent some time looking into what you just explained and I have so many questions now 😂 - Why shouldn't I permanently connect the EPS Neutral to ground at all times? It’s illegal (in the UK) to connect an off-grid system to any of the i...

Ambient temperature is the internal temperature of the inverter, InvTemperation is the temperature measured on the rear cooling fins. One follows the other, the InvTemperation (fins) increases when the inverter is working hard, i.e. lots of solar generation, battery charging or heavy discharging - w...

Interesting little project, assuming the timer will operate in a delayed on mode I can see nothing wrong with the functionality. You have an earth rod fitted which is correct, the one omission is significant and can be dangerous - you *must* create a Neutral to Earth bond when the grid is disconnect...

Hello everyone! This morning I decided I was going to simulate a power cut to test out the automatic switch over of my EPS system, and I'm glad to say it worked great. I wanted to leave it do its things for a few hours to explore this "EPS Mode" a little before turning the grid on again, ...

I doubt CT over LoRA would work, but the hard wired connection should have, personally i'd have got that working if at all possible - less things to go wrong. If they are talking about a meter then they will replace the CT clamp with an RS485 meter that measures the power instead (such as Chint or E...

The hybrid inverter won't operate without a CT clamp as it cannot measure and balance the loads. The CT clamp that comes with it is connected by a 10 metre cable, the CT clamp itself clips round the live tail of your smart meter, and the other end is wired into the CT/Meter connector of the inverter...

Which app are you using, V1, the latest V2 or Energy Stats ? V2 and Energy Stats (by Al Priest) show the most information, so i'd recommend if you're not using them to try them. Also just to mention you can log into the foxesscloud.com and see your system there, that shows more information about you...

Hi, It's not supported as such (other than by cloud which you could use the foxess cloud integration for https://github.com/macxq/foxess-ha [which is relatively easy to do] ) But have a read of this thread (https://foxesscommunity.com/viewtopic.php?t=740) if you are electronically minded and fancy a...

Is your work mode set to 'Self Use' ? I can see you are using the V1 of the app - are you able to switch to the newer V2 app, that is much easier to use and you will be able to see the work mode at a glance. The thing to mention is that the screen you are looking at is not real time, it's a snap sho...

The F6000 inverter as you say is a solar only inverter, as standard it simply outputs the solar generated to the grid at the maximum possible power. If you have 3 * F6000's then unless there is an export limit set for your installation then all will output at maximum power. If you have an export lim...

I’ve never heard that before, but a couple of things to check - Try logging in on the Foxesscloud.com website with the same credentials - that really should work, if it doesn’t it would appear the user account has been created correctly. If it does work, that prove their credentials are ok, so next ...

I'm not sure what you mean about the Force Charge and Force Discharge running together, so i'll set out what I know and hopefully that'll help. Before the schedules were introduced you would have used the old 2 charge periods, these work fine and will continue to work fine *unless* you set up a sche...

Your grid voltage is too high for the limit set in the 10 minute alarm setting - if you are in the UK you should be able to call your DNO and they will measure it and address it if necessary. You can adjust the alarm limit, look at the max grid voltage your inverter is reporting and set this limit t...

As a general rule, the master will power up with no slaves connected as long as the dip switches are set correctly - even if they are not you would expect it to flash an error code. You should be cabled to the inverter as per the manual DC+/- and canbus connected - and at a minimum you need to have ...

That sounds about right,

To do some quick maths if you assume 45% at midnight and 20% at 6am, then 25% of (2*2.38) = 1.19kWh for 6 hours or 198 watts per hour so you obviously have quite a low house base load (fridges, clocks, chargers etc..)

It's perfectly normal to do that, the inverter and batteries takes some power to stay operational and ready. This is taken from the DC side rather than use the grid (DC = batteries or solar during the day). The amount of power it uses depends on the inverter and the number of batteries you have but ...

Great, glad you have sorted it

So a couple of things, firstly is the range of the new router as good as the old one - i've heard the BT routers range is lower than some, but I can't confirm that myself. If you stand next to the inverter with your phone is the signal strength still good ?. Secondly most modern routers transmit on ...

Interesting thread thanks. I'm considering buying 2 K series inverters - KH7. I'd like to store up and export too. However is regular force discharging to grid wise ( assuming its now possible)? Won't it eat into your cycles limit? The batteries will only do 6000 cycles? What is the definition of a...

Thanks for that Dave, really helpful to have it all in one place. No, I don't have agent access, and given there's just been a firmware update (hasn't there?) then I'll contact FoxESS to update them all. Are the dip switches just an old idea that's no longer needed? And, does turning off the AC to ...

I was delighted to find that my KH10.5 inverter (installed 2/4/24) had the firmware to allow forced charge and forced discharge of my batteries. The only issue I have is that whilst the forced charge runs at 10kw, the app (Android version) only allows a forced discharge of up to 6kw. This seems par...

Your app suggests that you have very limited draw from the grid as you say - so something is wrong somewhere. Is the app displaying the other power variables such as the house load, any feed in etc.. correctly - could you post some of the graphs you see for those as well please. As you say something...

That is unusual, as if you have an export limit set on the H3.

If you can access the menu on the inverter panel for the H3, go into Setting and On-Grid, Export Control - this should be set to 60,000 (sixty thousand) anything less and it will limit the export power to that value.
