Got a slightly better deal on gas the other day too. Exclusive Octopus 12M Fixed, 2.39p a unit and 17.85p standing charge.

How did you get the lower gas rate?

Just emailed them and requested it.
You can choose any gas tariff they offer and combine it with Go or Agile. You don't need to stick with the standard gas tariff.

I'm aware of that, but where do they offer such a low rate?

Thanks, I guess they are making small variations to gas prices based on location as the best I can see is 2.48p/kWh.

2.16p pkwh gas in the north.

I am currently offshore Egypt so viewing system remotely. Bought a 3rd battery which will allow an increase of discharge rate to 3.6kw. Also allow more variance in how much I charge at night and pre 4-7pm window of pain. Noticing that solar has increased to around 8kwh per day and too much of that is being dumped into hot water tank.

Will change battery charge timings when batt 3 installed next week on my return to base. All good so far and enjoying Agile.
Cheers, p.s retiring after this job, oil industry bothers me now.

Agile prices seem to be increasing again in our area, probably due to less wind power now the storms have past.
It's 34p at 6pm tonight and only been below 5p a couple of nights for a few hours lately so I think I'll stick with Go until next autumn/winter.

It is the standing charge that gets you on GO. However the majority of days “go” gives you cheaper overnight electric than “agile”, with no 4-7 peak to contend with, and you can set-and-forget all of your timers.

I like the idea of “agile” and who wouldn’t want negative pricing. But it doesn’t make sense when you think about it.

The difference is only 4p a day so £14 a year.
Go still works out better for us at the moment. We averaged 5.99p last month.

For the reasons listed in my answer!
  • Most days you get cheaper overnight power on "go"
  • There is no early evening peak on "go"
  • On "go" you can set-and-forget all your timers

It depends.  I was on Go for a bit, but with my Powervault, I could only recharge 2.8kWh back into the battery at the lower rate, which then didn't have a big enough impact on the main day rate, at least in the darker months.  Agile is a bit more flexible (ha ha).    Mind you with Agile I have also had quite a few nights where it's made sense to use the timed boost function on my ImmerSUN to get some very cheap hot water - so that's been useful too.

Maybe Go Faster could work for me, I might try that if I get bored of the more hands-on management that Agile requires with my current hardware.

What is the rate of charge for your Powervault? I'm looking to upgrade from 2x to 5x PylonTech batteries (11kWh usable power) before the winter, I'll be able to charge them from empty to full in c. 3hrs!

I've been on Go now for almost a month and the four hours cheap rate has been sufficient on most days to get my batteries back up to 100% from whatever capacity remaining they were at when it kicks in at 00:30.

If they are discharged to 20% (which is as low as my inverter will let them go), then they'll get back up to 75% by 04:30.

The max charge rate on my Powervault is only 700W - so in 4 hours it can only suck in 2.8kWh.  It'll discharge at 1100W max - not sure why the two are different.
It's their old washing-machine styled Powervault with 4kWh of lead acid batteries, so not an all singing all dancing lithium unit.

I have half wondered if someone on here fancies seeing if it can be bodged to have a few more batteries jammed into the chassis...

Lead-acid has a poor round-trip efficiency. Modern LiFePO4 batteries can get c.95% round-trip efficiency.

You can always add more batteries but your 700W charge rate is the deal-breaker. Modern systems charge/discharge at 3600W typically. The 700W in 1100W out isn’t bad for storing excess solar, or even economy 7 grid power. But for the short periods of cheap power on “go” and even more so on “agile” you really need to be chugging back the power. Some people are sucking in 20kW!
