That's definitely the way to go when the solar isn't performing, I'd be doing the same If my smart meter could get a communication connection!

 I don't know if Agile or Go tariff is best. Also do not have a DNO yet, do I need it to start feeding power ?
 I now have my PV installation in and working, Octopus have me on the priority list for a Smart meter so I can start getting paid for any excess (not much this time of year)

If you want to get paid for the excess, I presume you mean through Octopus "Outgoing", then you cannot be on Octopus "Go", but you can be on the "Agile" tariff.

You also need an MCS certificate and DNO notification/response.

Yes that is exactly what I mean, sorry for the mistake, so its either Agile or Fixed

In order to utilise the Octopus Go tariff in conjunction with the Smart meter as much as possible I have been increasing my import whilst monitoring the temp of the cables to find the limit of what I can import during those cheap 4 hours.

I have a 100A main fuse on my single phase domestic supply, main isolator and CU are 100A rated, meter tails are 16mm2.

I hit a continuous import of over 19kW which was a little over 80A last night. This is the highest I have imported and think I have reached the limit. The incoming supply cable was very warm, main fuse and meter tails felt hot, I measured about 60 degrees with an IR thermometer. So internally they may have reached the max cabling operating temp of 70 degrees.

Main imports
Home battery charger - 7kW
Electric vehicle charger - 7kW
Storage heater - 2.5kW
Heatpump - 2kW

So far, with the help of my home battery I have kept my daytime import to less than 1% of the cheap period and I am seriously making a dent into my gas import by running the heatpump as much as I can.

Hi

meter tails are 16mm2.

Should be 25mm now(on new installs), 20 minute job to change if you competent, have a clear conscience and some side cutters!!

And a valid Part P certificate in your name.

As for 16mm2 being feed from a 100A capable supply when I looked into it for my own upgrade work I came across a statement that 16mm2 was 'OK' if the sustained load can't exceed 87A, but there were also caveats about there needed to be very low impedance at the terminals.

Unfortunately I got this from Octopus last week which os a bit of a dissapointment.

You will need to be on the Octopus Go tariff to make use of this. Unfortunately, this requires connection to a smart meter and working half-hourly reads that your meter is not currently sending to us due to wider issues with the smart meter portal.
Once the meter is properly connected we will be able to put you onto this tariff
.

Suppose will just have wait !

That's a bit disappointing as I thought the SMETS2 used a radio network signal (Arquiva) rather than mobile phone network, which gives it a better coverage (or so they say!)

Wales, and Southern & Central England have O2/Telefonica doing the comms, and it has largely been successful, with a few odd exceptions. North England and Scotland have Arqiva, and have had huge problems.

My installer mentioned mine would be O2, I am on the South coast. He also mentioned something called MESH, he said that if you could not get a connection but someone else nearby (don't know how near though) with a SMETS2 could, then it could be set up to communicate with another nearby SMETS2 meter, and then piggy back onto it. Of course this is only going to work, once there are other SMETS2 meters actually installed nearby.

Of course this is only going to work, once there are other SMETS2 meters actually installed nearby.

It gets even more complicated as a number of different network standards are on the list which back in 2013 included - 2G/3G cellular, wifi, power line IP, and Bluetooth. So nearby connected meters may or may not be able to form a meshed connection based on what standards the meters support. This may get even more complicated as newer meters start to support newer standards such as SIGFOX (a Low-power Wide-area network LPWAN provider) rather than the older options.

I tried get a smart meter installed at my late fathers (the E7 timer was bust) the EDF guy said he could do it, but on the day they had problems with them being 'commissioned' onto the network. If it didn't commision they would have to take it out again Huh. The whole procedure could take 3+ hours facepalm

In the end he just changed the timer. Roll Eyes

During this winter period I am finding that a little more battery charging capacity would be handy in order to put more energy into my batteries during the bonkers Octopus Go 4 hour cheap period. I have been using my heatpump more and its significantly decreasing the amount of gas I am consuming and therefore reducing my Co2 emissions even further. But using the 6kW charger in my Sunny Island is not quite enough in the short 4 hour cheap window and this is limiting my heatpump usage.

I started to think that I could have used my Sofar Solar MS3000SP which I sold because it became surplus when I installed my Sunny Island. facepalm
 
So I have now bought another one and this time I have not fitted the CT clamps and I am just using it as a timed battery charger which gives me another 3kW of charging capacity so I now have 9kW of charging power for my home battery. Been running it for a couple of days now and I now get a total battery charge current of 166 Amps, up from 107 Amps, so it works. extrahappy

We had a SMETS2 fitted last week and we got the confirmation email yesterday that we're now on Go. I charged our EV and home batteries last night during the 4 hour 5p period but the wireless display is showing our useage at the full peak rate price.
Are these displays not capable of calculating the 5p rate or do we have a problem with ours ?
Also, our gas meter doesn't appear to be talking with Octopus yet as there's no consumption figures showing on our account online, just the leccy.
Do the gas meters take longer to 'sync' with Octopus or should it now be working like the leccy meter.
