Well, the replacement MCB is in, and the cover is back on. It was isolated from the grid by the RCD, but I still wore my wellies and marigolds.

The system is up, and has been running for over an hour so far.

I put a Hager MCB in because I couldn't get a Live one till gone Xmas, and couldn't face ...

Based on what does and doesn't happen when the MCB (and or the RCD) trips, I'm pretty close to certain that diagram shows where the PV MCB and RCD connect in my system.

The only question that I don't think there's evidence to answer, is about the relative positions of the RCD and MCB. If they are ...

I have an older issue of that manual, but I couldn't find any ref to the MCB and where it's connected in. Then it dawned on me to look for the RCD to see if I can infer the MCB's location from that. So the diagrams on page 30/31 in my copy (35/36 in the one you linked to), which I've included ...

Stop resetting it and contact a professional, you have a fault that needs to be traced and fixed.


I'm sure that was intended to be couched as advice, rather than as a direct order. Anyway, I will consider it as such.

I certainly wasn't going to sit here waiting for the installers engineer to ...

Is the current flow through this MCB bidirectional, so if I turn off the RCD, it's still live from the grid?

If that's true, where can I turn off the rid side?

The MCB is now tripping frequently in the day, 3 times already today. It also does not want to reset, takes a couple of goes to latch it, and feels weak when I'm setting it. As I remember, that's like the MCBs I've had fail in the house box before. I wonder if it will feel unusually warm if I catch ...

Is it likely any earth fault would trip the MCB without tripping the RCD? That is what's happened these two times.

If it ends up being down to me, I reckon I'll just swap the MCB and see if that fixes it. I assume, with the RCD off, that's a fairly easy job, same as in the house fusebox.

It went again at about 3:30 am yesterday morning. Looks like it coincided with it stopping charging, with hardly anything running but the fridge. It's cost us a few quid powering the house at day rates for the electricity all yesterday, but we start today with the battery still full.

This is a ...

It's a LIVE CA132b, 32A circuit breaker, which had tripped. That should be good to 7.6kW at 240V, where the system reports itself at drawing and giving upto 5kW. Should I be concerned the headroom is a bit small? I usually go for a factor of 2, e, or Pi, rather than root 2, for mundane systems ...

I've just found I had the same problem. The error log gave this, Tuesday, morning as the time, but looking at history, we've had no function since 19:27 on Sunday 1-12-24.
I've reset it - I'm not sure that it took the first time, so I did it twice, and now we are charging, etc. I hope this is a ...

duplicate?

my installer is still in business but the tech guy refuses to answer or return my calls, I think because he does not know the answers to my queries (eg how do I integrate my system to Agile rates on octopus). There are also a couple of issues with the install. If they refuse to engage with me how ...

Secure boot can be turned off on this laptop - there's a switch for that, in the BIOS that can be accessed, so I assume it will work.

I see it is possible to install HAOS direct onto a 64-bit X86 machine: https://www.home-assistant.io/installation/generic-x86-64/ . So I could swap the 128GB SSD ...

There's a hiccup in the plan to use the HP laptop, in that the advanced bios access is locked by HP, and they want more than it's worth to unlock and make it boot on AC power. But, maybe, boot on LAN will do instead, as we don't see a lot of power cuts. I'll test that today. There are suggestions on ...

Oh, I assumed I could run HA directly over a native Linux OS - I don't know Linux well at all, but I was told by a man who says he knows what he's talking about that there'll be no issues installing it on an HP Pavilion Notebook 15-ab040sa from 2016.

So I was going to install Linux on the new SSD I ...

Well, I changed Time Period 2 to 00:30 to 07:30 with Enable charge from grid on. Now there's no time for the battery SoC to droop before it starts to charge, and it does not look like there's any charge going into or out of the battery after it reaches 100 %.

That helps what I'm trying to see ...

That kit you linked on ebay sadly won't do it, it's basically an emulator that runs the raspberry pi dashboard - not a raspberry itself


I was wondering about installing Linux on that directly and running HA under that.

So, with the x86 machine, I have to run Windows and a VM to run HA ...

With a bit of minor adaption you can create your own dashboard which shows only the key sensors, statistics and graphs you are interested in
You can also define your own sensors if there's calculations you want done that HA doesn't do by default. You can also define "utility meters" to give you ...

Anybody able to explain this:

I have battery charging Time Period 1 set to 00:30 to 07:30 with Enable charge from grid off, Time Period 2 set to 04:30 to 07:30 with Enable charge from grid on, and I start from an SoC of 65%, so the battery charges to 100% by 05:55. From 00:30 to 04:30 I have a ...

So, something like this https://www.ebay.co.uk/itm/256038764507?hash=item3b9d197fdb with an £8ish 120Gb SSD? I assume I can download HA to a USB stick and transfer that way. Cloning the SSD that's in it might be a problem if it's an M.2.

As to exporting the data to the Windows 10 laptop, I really ...

Sorry, I meant virtual machine, i.e. logical partition, not virtual partition.

But if I can install a Linux box near the inverter running HA, and see the data that records from a separate Windows 10 machine, that would do. So what app would be running under Windows 10 to log the data and apply ...

If I was to install and connect a Linux machine running home assistant to the inverter, would I be able to monitor that from and extract data to a Windows machine over the wifi, e.g. via a browser?

Graham

I've thought about the home assistant option, but it looks more involved to implement than I want. I don't mind buying a Pi and SSD, and probably aren't worried by the physical installation and cabling etc. - even running an Ethernet cable into the loft wouldn't phase me. But I don't want to get ...

Thanks, that looks a fairly comprehensive cover of the general rules. I'll need to study it for a while, though.

I take it that the temperature I should be concerned about is the battery temperature as monitored on the app. However, it worries me that, as someone else has noted, I’m seeing higher ...
