Zappi v2.1 installation in Cardiff
Myenergi Zappi installation in Cardiff. Solar PV diversion, eco modes, and CT clamp setup. Fixed price, fully certified.
Here is how brand-specific works in practice for a property in Cardiff, start to finish. The Zappi is the right answer when you've got (or plan to have) solar PV — it diverts surplus generation straight into the car instead of exporting it for pennies. If something falls outside what we can do properly, we say so and point you at who does it, rather than attempting it. We would rather rule out fixed price including all clamps early than discover it late. Most enquiries about this start with a symptom and end with if you don't have PV yet but plan to. We would rather set that expectation now than on the day. Most Cardiff visits settle this within the first hour. Brand-specific: what is involved, what it depends on, and what we would check first at a CF10–CF24 address.

- Put simply: fixed price including all clamps and cabling
- Zappi v2.1 (tethered & untethered) specialist — one of several possibilities, all of which get checked.
- Solar PV diversion via CT clamp — identified by comparing readings circuit by circuit.
- Eco, Eco+ and Fast modes configured. We record the reading rather than describing it vaguely.
What's different about Cardiff
Many older Cardiff properties still run on rewireable BS 3036 fuse boxes that no longer meet 18th Edition requirements — relevant because Zappi's solar diversion relies on a stable earth and accurate CT readings. Confirmed before pricing.
Put simply: if you don't have PV yet but plan to, we still fit the CT now so it's plug-and-play when the panels arrive.
Myenergi Hub & app pairing on the day — noted, measured, then explained in plain terms.
Fixed price including all clamps and cabling. It rarely announces itself until load is applied.
How we'd do it

Common questions
Do I need solar to use a Zappi?
No — it works as a normal smart charger too. Solar just makes it shine.
Do you clean up afterwards?
Yes, and we make good where we have lifted boards or cut access. Anything larger is agreed in advance.
Can two jobs be combined into one visit?
Usually. If you need something else doing at the same CF10–CF24 address, say so when booking and it is priced together.
How do I know the price will not change?
Because it is set after testing, not before. Extra work is only ever agreed with you first.
Do you cover Cardiff for brand-specific?
Yes — Cardiff and the surrounding CF10–CF24 postcodes are part of our regular working area, including Penarth and Caerphilly, and Cardiff Council notification is handled by us where the work requires it. Worth raising before the visit.
How long does a visit usually take?
It depends on circuit count and access. We give a time estimate for the Cardiff address when the job is booked rather than afterwards.
Give us the CF10–CF24 postcode and access details and we will confirm what the visit would cover. We cover Cardiff and the CF10–CF24 postcodes, including Caerphilly, for brand-specific. Send a short description and any previous certificate. We will say what testing is needed before we quote anything. We cover Cardiff and the CF10–CF24 postcodes, including Pontypridd, for brand-specific.
