The sensor updates every 10-15 seconds normally but home assistant only shows the updated when the value changes.
Mixed version systems can do odd things but ultimately, 300 watt hours is not enough to really worry about. Remember your existing stack might have wear so the total kWh will be less ...

Can you upload a picture of the lights and I can compare the lights with the error codes in the manual.

Do you have an export setting set to 0? that would disable export

Too many variables to give you a good answer. Could you explain more about what is happening and what you are expecting and I’ll have a crack at clarifying for you.

make sure you put it into airplane mode, then only enable wifi. Phones are too clever nowadays and will try to bridge wifi with mobile networks when it can't access the internet causing the browser to stall. Airplane mode solves this.

I would delete your schulde completely and then try again from scratch. Sounds like it's got itself in knots.

It's very sensitive and unintruitive currently.

My advice would be to make sure with your installer that your firmware is up to date as there have been improvements since initial release.

Then you have to set it and not touch or make any changes or you maybe accidently disabling it.

You can use either, the pro is the newer for powerful model. details here https://pk.fox-ess.com/download/upfiles ... 241125.pdf

If the battery is not force charged to full regually the bms can get out of calibration. When did you last do a from grid force charge to 100%?

The fact that there is 0 current and assuming it's daytime might be a issue with the pv wiring.
If that voltage and current is correct then I would first upgrade the firmware to latest and then make sure the pv wiring is correct as per the fox manual. You can't parallel panels. Fox only support ...

Those are push connectors on the new gen2 plug. You simply need to push the orange tab in, insert the wire and release and it should have a good strong connection. Check the guide to confirm the pins but I believe it's pins 3 & 4 https://github.com/nathanmarlor/foxess_modbus/wiki/Modbus-Wiring-Guide

in the meantime while you're waiting for your mcb to be upgraded to a larger one you can set the inverter limit to 70% so it's stays within the 32amp limit.

depending on firmware version of the inverter the modbus addresses changed in recent firmware.

I don't know if it will help you but all the working addresses are used in this project

good luck, post photos when all installed.

Short answer, no. You should keep each string to a single loop for a string per mppt. Combining or using mixed panels is not supported and will cause issues,

When you look at the real time data flow graph do you see the battery providing any power?

Fox are aware of the issue and working to resolve. https://monitor.foxesscommunity.com/

Exciting news! we have a group discount from Eco ESS on auto changeover switches which really solve the lack of a fox gateway.

Oh yes, you will need to enable it on the inverter.

My answers in bold.

Should that information be available from the inverter that has been fitted or is it only available from a more sophisticated inverter? Without a CT clamp you will only see solar generation in the app. No grid data or house load data
Is that information only available for ...

Hi and welcome to the forum, can you confirm exactly which battery model you have and how you're monitoring the discharge/charge kWh. Any screenshots would help.

Correct, discharge to 50%, isolate battery stack and inverter and turn it all off.
Remove data and earth from BMS. Unplug the HV leads from the first battery, lift off the bms and place to the side.
Carefully add the batteries, make sure you don't accidently short circuit the batteries. Always make ...

No, you have to have 4 of the same. So 4x EP5 (non-heated), or alternatively you could ebay the EP5 and then get up to 4x EP11-H or 4x EP5-H.

If you were to add an EP5-H alongside your existing EP5, you would not be able to use the heating functionality because it is only enabled when all the ...

In addition to Dave's correct and accurate advice I wanted to give a fresh idea.

As you only have 2 x HV2600 and they're rare and easy to sell, why not sell them and install a brand new stack of ECS cubes? Keep the same inverter and all the wiring, just replace the batteries.
ECS cubes start at ...
