Hi Dave, how are you doing? The warranty was 3 years. The recon unit would be of the latest version, but I have similar concerns, hence my second question. I've spoken to the installer, who says he's come across this issue before and, in his experience, it's not something that can be easily (or economically) fixed. Online searches suggest it can sometimes be caused by a loose terminal or broken contactor, or a faulty relay, but I wouldn't have a clue what to look for, and even if I did I wouldn't have confidence in being able to safely dismantle and fix it.

Hi all, long time no post, but I still loiter. As the subject says, our Myenergi Zappi has failed (output failure error), irritatingly just 16 days out of warranty. They're offering to supply a recon unit "as a goodwill gesture" at a cost of £349 + VAT, but I'd have to arrange fitting myself. As those who remember me will know, electrics is a black art to me, so my questions are.... 1) how easy would it be to swap out the old for new, ie does it need to be a specialist fitter or could any competent sparky do it? 2) should I be considering an alternative solution? Thanks in advance for any advice 👍🏻

Whilst I can't prove it, I suspect they are busily adding qualifying text where it previously wasn't provided. My guess is that it was there for previous variants, but was left off of documents covering the 2026 model year updates. Whether that is because they had intended to improve the charging rates, but then didn't, or because someone dropped a clanger - who knows.

In theory, yes, but that's not the point. Here's the document that appears if you put my model details or reg no into Volvo support, or pull it up in the vehicle itself. https://www.volvocars.com/uk/support/car/xc60-plug-in-hybrid/article/0ed816eed33d98cac0a8cc377bc12bc7-83c0c849d91ad5fac0a8cc3751bbe62b-8664b2fa77a7e089c0a8296870d1a409/ No mention of needing 2-phase.

19kWh, so 5 hours as opposed to 3.

No diagram, and nothing more than the statement above. I made a formal complaint to Volvo and they referred me to a document, dated November 2023, for the 2024 model and said it was the applicable document, not the one embedded in the online manual for my 2026 model and dated April 2025. They have refused my complaint and I have now complained to the Motor Ombudsman (though not holding my breathe), so am gathering evidence for that and for a potential legal action. I really don't like being taken for a fool.

Thanks @-rick- @Nickfromwales . In the manual it simply states that the max charging rate on a home charger is 6.4kW, but in a pdf buried on their web site it states that the car has a "2 phase on board charger" and that home-charging on a single phase supply is "limited to 3.7kW"

Thanks for that, Rick, but what I'm trying to establish is just how rare 2-phase is in the UK? My contention is that, if it's as rare as I believe, quoting charging rates based on 2-phase is both misleading and disingenuous.

Long story short, I bought a new Volvo PHEV and it doesn't charge at the expected rate on our Zappi home charger. Volvo contend that to achieve the higher rate (6.4kW) you need a 2-phase 16amp supply. My contention is not merely that the technical manual does not state this, but that single phase is the standard domestic supply in the UK so why would they quote a charge rate based on a supply type that is (at best) rare. What I am struggling to identify is just how rare? Any wisdom on the matter would be greatly appreciated 👍🏻.

Sounds to me like you're making the right decision. There'll be other opportunities, you just have to wait for the right one, or at least the one that gives you a better feeling about achieving your goals.

Okay, that sounds like a possibility, thank you. I'll speak to the dealer when I collect it tomorrow 👍🏻

Not via the Octopus app, no. They say the app cannot recognise more than one vehicle, and the only way to charge the second one us to do so manually, which (to benefit from the 7p rate) presumably means plugging it in after 11.30pm.

As per the title, is anyone doing this? My new PHEV arrives tomorrow and Octopus tell me I can't charge it as well as my wife's EV via Intelligent Go (not simultaneously of course).

7.5 years in, total net energy cost is -£730. However, last RHI payment was received a couple of months ago, so I may now look again at whether it's worth us adding a battery.

We never open windows. In fact, but for the requirement to have openers for means of escape, we could have saved a bundle by having all fixed panes. After 7.5 years living with MVHR, I can't imagine ever going back to living without it.
