Thank you for reaching out to us. I understand your disappointment regarding the confusion with your switch. I apologise for any inconvenience caused.
I want to assure you that we value you as a customer and we want to resolve this issue for you. I have taken note of your dissatisfaction and closed it as feedback log. Please be advised that messages you received were automated because of account attempting to switch without success.
The previous statement that you will be updated when migration happens is correct. After you switch I have left note on complaint that we would need to book engineer to visit you and install smart meters.
In the meantime, if you have any other questions or concerns, please don’t hesitate to let me know.
Kind regards,
Sanjin

I am very disappointed that my application to switch over our supply has gone wrong. You Said –
“We’ve been notified by another supplier that you’ll be switching to them from 18th January 2024. We’re sad to hear you’re leaving us, but of course the choice is yours.”
How did I choose to leave you?
But you never got on with the transfer, saying that the migration from Shell Energy was going to be automatic and completed in late December.
Where do we go from here? All I wanted was a smart meter that worked properly and a flexible tariff.
The system I had put in was 5.8 kw Solar panels Givenergy Hybrid 5.0 (gen 2) hybrid inverter (for AC and MPPT solar) with a Givenergy battery of 10.4kWh made up of two of their 5.2kWh units all in my loft. Then a Myenergi (Zappi) EV car charger and Myeddi hot water excess solar diverter. BTW because I was having more than 4kw installed I had to get permission from the Grid DNO (SP Energy for us) via a G99 form (the installer did the submission) and took 6 months to get an affirmative response.

We changed from Flexible Octopus to Octopus Go early January and started using off peak forced charging on the 8th Jan.
Our daytime rate is 25.57p/kWh (1.4p per unit dearer than 24.15p/kWh on flexible), but nearly all our consumption is now covered by the battery with a tiny bit of help from the Solar panels. The off peak charge costs 8.5 p per unit, so if we add on inverter losses, you could say it costs us 10p per unit.
This is a graph for yesterday (rubbish sunshine!) so we ended up using power from the grid again after about 7pm, unfortunately:
This from yesterday was not very conclusive, I shall try again and next time take a normal photo of the boards from the same angle. Also I shall take the infra red thermometer to read the temp of the chips. The problem is, there are two layers of circuit board and its hard to get a clear picture of the back one whilst it is running. I shall also try and position the cross hairs of you camera on a warm chip to see what that comes up with. I think I am going to have to get a fresh unit in the end, but at least I’m not wasting solar power this week!

Having failed to get this invertor talking to my Darfon BMS https://camelot-forum.co.uk/phpBB3/view … 480#p49480, I had 3,480 kWp solar fitted on a big shed (435W each x 8) last week and connected them in two strings 1 West and 1 East facing for comparison before potentially increasing the number of panels on the most effective side.
I have not yet got the remote monitoring sorted, but have got a LAN cable from my router connected to it in readiness. Not impressed with the SolaxCloud so far though.
The inverter display panel shows the voltages from the panels soon after booting up, but after a while the display freezes and is not responsive to button presses. I wonder if the thing is economically repairable or is it time to think about a replacement? Or is it just “finger trouble” on my part?
It seems to be fairly consistent, When the DC, the panels and lastly the mains are all connected, there are a few relay clicks from within, then the display buttons work and the setting can be changed after entering the Pass key and solar powers are shown on screen for half an hour or so, then it freezes up, often with the screen below:
I asked the question of the BMS repairer: “I wonder why this growatt battery says 57.4volts, yet the Solax inverter manual says it should stop charging at 53.5 and start again at a minimum 47v ? ” David
He replied: So, this is one of the reasons that these batteries are not compatible with other brands of inverter.Thery work at a slightly higher voltage than other brand batteries.The only way you will get this system working is to add a Growatt SP2000 to charge the battery or replace the battery with one that is compatible with your Solax inverter.Kind regardsChris
no voltage on the BMS output. The battery is showing 55.3 volts before the BMS

All of the packs should be within 0.2 volts of each other but ideally the closer the better. The BMS locks out if any of the packs is more than 0.2 volts higher or lower than the rest.
Also, if your SP settings are incorrect this can over time damage the battery. Some installers change the settings to maximise the yield from the battery but this discharges the battery too low. The settings should also allow the battery to be recharged to a minimum of 10% as soon as the PV is next active after a complete discharge regardless of home load

charging bad cell pack at 4.2v constant voltage
We have partially stripped down the old Solax battery and I am starting to get a feel for the job ahead. Last night we took the one flat cell pack out and started charging it via its neighbour using a 12v lamp at 5pm.
PIR floods usually help but are not essential and dependent upon the position in relation to the camera can cause reflection and in some cases a 1 or 2 second distortion of the image as the camera switches from Night to day mode. I’d install the cctv and cameras first and see how it works both day and night before adding any additional lighting.
