Looking at some of the prices on Fogstar for their EVE based packaged batteries it's not worth the effort to fully DIY it, that said, I really did enjoy my little project. If you do decided to go the DIY route, if you want any laser cut frame parts just give me a yell, material and post cost for...

What ever makes you comfortable is good. I do download all of my data to analyse the performance etc of my solar and battery systems. It makes for interesting reading (sad I know but I'm retired now :)).

I have been an Octopus customer for well over 6 years now, not once have they deleted data and they have always been helpful when I've requested longer data dumps than I could get online. They are far from being a 'shady' operator.

The lottery is a scam, don’t do it 😝😝😝😝

You know what it’s like when good things happen, the feeling of elation, stand up straight, head in the clouds etc. I have a great feeling for 2024, look at this for a great start to the new year. 520,000 euros, that’s not a bad start 🤪

Problem is the Nanny State here and no common sense. I absolutely agree with you that a complete unit replacement is ridiculous, compliant but ridiculous.

With some of the Octopus tariffs available this all becomes a no brainer. Export any excess you have at 15p kWh, import off peak as low as 7.5p kWh. I can't honestly see the logic in running the system how you are.

Do you have a tariff that gives you off peak energy at a lower cost eg Octopus GO? If so I would adjust the charging schedule to charge your battery to 90% for the full duration of the off peak time (for GO that would be 00:30 to 04:30). The house loads would all be supplied at the off peak...

This is changing in February 24 and batteries can be purchased later with VAT at 0% https://www.gov.uk/government/consultations/vat-energy-saving-materials-relief-improving-energy-efficiency-and-reducing-carbon-emissions/outcome/summary-of-responses

I personally would turn it around the other way, look at your daily consumption figures and get enough battery storage to cover that plus a backup margin. Look at your peak consumption and use that to size the inverter. That creates a battery system that can run the house all day at off peak...

380w on the HC version ? This would put me off though: "Enphase University certification is required to commission IQ8 Microinverters in systems with backup (Sunlight Backup, Home Essentials Backup, and Full Energy Independence)."

He must have a wonderful life if the guarantee on light switches is high on his worry list. Thread now closed

We managed with just 2 kWh of import with batteries and solar feeding the 29 kWh of consumption. Really happy with it all. Not running the heatpump at the minute due to low price of gas.

I understand, just from my experience with Growatt this phenomenon happens just after sunrise and just before sunset type levels of light. It's bloody annoying and I have struggled when one of the saving sessions was announced to get my Growatt battery charged before the session, in the end I...

Down to <15% of the normal charge rate the Growatt spec giving operation temperature of -10 to +50 degC ?

Hi Bob, Sounds like you've achieved your goal after many hours of frustration, well done. It will be interesting to hear how it performs over time, please do keep us updated. J

And the waiting time for it it boil every time more pounds.

Not really 😎

or use gas, but that's not the point as you know 😜 We dont have a kettle as such, we have a hot tap anyway.

I was in a similar situation 2 years ago and finally settled on a quote from a company which seemed to make most sense. The planning and installation was done with a prompt and efficient workforce and the system worked well. I did however find some shortcomings. The inverter (Growatt SPH6000)...
