More batteries needed but am not a leccy so concerned I might kill myself going DIY, which is clearly the best option financially!

What, killing yourself? Well insured? :lol:
I found that EV, storage heaters and a solar hot water diverter can utilise all the power we generate. The solar diverter will store at least 12kWh in the HWT, the storage heaters will do North of 80kWh but not great in full Summer. EV can store 70kWh. If I tried to convert all that to home battery I'd be bankrupt (and dead).

Well worth a walk through your own place to see what other forms of battery work for you? Or indeed the A2A HP's that are used for air con and heat?

Last couple/few of days have been rain,cloud and also snow. Yet even with those unoptimistic condition the two PV systems have kept us going. At 16.30 today we are light grey skies in all directions and still pulling 1.1kW through it.

Combine that with the WBS and I have absolutely no complaints. Still not enough to be powering the EV in any meaningful way on an overcast day but HWT is getting a light charge most days and whole house is doing well.

Are the prices changing much? 🤔 I ask as although I don't track battery prices I thought I saw a fall back in the last E flyers in the inbox?

The Sunsynk battery has come down by around £200 at ITS in the last couple of weeks - I haven't noticed a similar change in Pylontech

That's good, I hope it continues to fall. I think I would have bee a 3 month gap or so looking at Pylontechs so that's likely why I thought there had been quite a drop.

We have a beautiful clear day up here. There is the very slightest of chances that PV up here combined with WT down there could give us our first 100kWh RE day. I spoke about this last year when we moved the second array around and could see it might align. Fingers 🤞 & inordinately excited.
