I did read that you could switch at will but that had been changed to 30 days but the way I read this I cannot switch to Agile directly from Go or am I misreading this

Your fine to switch from Go to Agile but the 30 day rule still applies.
So if you just went onto Go recently, you'll need to wait until you've been on it 30 days before you can switch to Agile.
So like I say, it's a bit of a gamble as your stuck on Agile for a month if the pricing goes high.
I'm sticking with Go for now as Agile prices are pretty hefty at the moment. 
That might change if we get high winds coupled with another full lockdown like in the spring.

I’m sticking with go at least until spring when the sun starts to shine again ... the way I read it was cannot move from one to the other directly ...
thanks for the clarification

My first night on Go and batteries only up to 80 % during the 4 hours looks like the temperature is too low to get a full charge. 

Initially 44.4 A then 66.6

EVandPV

The charge rate always starts to taper off when it gets to about 80% Mick. Same with an electric car.
I see you have 10.5kwh of batts so it's probably the case that 4 hours isn't quite enough to charge them to 100% at 66amps.

Hi Thanks

I think we have been here before re temperature, they only charge at 44 for a while then 66.6.  In n the last 30  mins according to the SOC% chart charged % does not increase.  My son has the same battery power and he manges to charge his to 99% in the same time period with the same settings (I set them up so they are identical to mine) his batteries are inside his house over 4 hours charge they charge at 44.4, 66.6 and finish at 111 A

No worries though "Go" should still save me a £ or two over winter

EVandPV

Just checked mine (7.2kwh) and the charge rate starts to taper off from 75amps (100% charge rate) at 88% SOC.
The last 12% of the charge takes about half an hour .
You might find the charge completes if you set the charge rate to 100% (you mentioned before that you set it to 80%).

Will try at 100%... if that works I will taper it down until it just manages it.. my batteries will almost certainly be down at 10% by the time the charge kicks in.  A bit of sun today and I will be able to top them up, overall I'm pleased with the battery addition but like everyone on here agree that they are not a cost effective option but we all like the "idea"

Yeah I guess time will tell.
Solarchaser and myself have nearly had the batts for a year and both our calculations put the ROI somewhere between 11 and 13 years.
I guess, if nothing else, we're doing our bit in a small way to take some pressure off the grid.

If they last that long I will be delighted.... My ROI will probably be longer I dont have a EV and am a relatively low user 

I am almost afraid to say this but any year now we will see a thread on Inverter replacement... life expectancy was about 10 years.. mine will be getting there next year .. Im touching wood

Solarchaser

Mine charge at 70% which is about 2.4kw.
I have 4 x 2.4kwh batteries which gets to 9.6kwh, around 1 kwh less than your 3 x 3.5 =10.5kwh Micky.

At the 70% they go from 10% to 98% in the 4 hours, so at 80% you should definitely get there. 
So yeah it must be the cold.
Perhaps worth insulating them.
At full charge or discharge I've never felt the batteries get hot to the touch, and mine are not airgapped.

The cables are rated at 70a, so if you were really seeing 111a I'd be quite concerned. 
If my inverters are running full power the cables are hot to the touch, and thats probably about 65-70a.

I had my inverter replaced last year, it was 5 years old.

On the roi point, if you fill it and empty it each day, roi should be similar,  if you cant empty it each day, then roi will be much longer imo.

I dont generally use the batts to charge the EV
