Key Features
Introduction
MyEnergi ’s Zappi rouse point is a smart EV charger for dwelling house and businesses . It ’s usable in four versions , each of which comes in lily-white or black . Tethered Zappis have a eccentric - two charge cable attached , while untethered fashion model have a socket – you ’ll need to use the type - two cable that came with your car .
All Zappis can be used as place upright - alone chargers in buildings without any renewable generation , and they have a decent bent of feature of speech for this . However , they ’re also design to be aware of any generation , such as from solar venire or a wind turbine . This make them a honest choice for balancing load and coevals , help oneself you get the best return from your dark-green ability generator . The Zappi come up with a three - year warranty , which you could promote to five years .
Design and installation
The Zappi is n’t the small EV charger out there , but it ’s nonplus a sensible and reasonably goodly conception . When it ’s not in use you could wrap the tethered interlingual rendition ’s thick cable altogether around it , and stow its character - two connector in a neat socket on the front panel . With five meter of cable , the Zappi will just about get through the far end of most eV , which is handy if you ’ve parked the incorrect manner around . All the same , it ’s best to take some measurements to verify you ’re putting it in the most reasonable place .
The Zappi has a backlit mono display that ’s navigated with four clicky buttons . Once set up , you ’ll belike only utilize these to change the cathexis program , or enter a lock computer code if you need to set one up to prevent someone ‘ stealing ’ a barren charge .
The display itself record whether the Zappi is charge , how much superpower it ’s supply , how much it ’s supplied in total and – in more complex installation – information on how much energy your household ’s generating or using .
While I ’m usually happy to install canonic electric equipment , EV courser are strictly a job for the professionals . A individual - form charger can draw a flow up to 32A and provision 7kW – tantamount to about three kettles being moil at once . You need a qualified lineman to put it on a consecrate circuit , and check that the resulting installing encounter all the necessary guard standards .
Unlike many EV battery charger , the Zappi does n’t require a separate residuary current machine ( RCD ) or earthing point , which could reduce the price or complexity of having it install . It does take an internet connection , though , which can be either cable or wireless .
The single - phase Zappi comes with a CT ( current transformer ) clamp , which in a aboveboard installation could be used as a storage-battery grid sensor to supervise how much mightiness the whole theater is take out from the grid . In many cases the Zappi will be near enough to your meter cabinet or fuse box that using this will be straightforward , but you’re able to bribe the optional Harvi wireless sensor if the cable television is Laputan .
If you have solar panels , a stamp battery , or other generation equipment , it ’s potential to fit extra sensors to make the Zappi aware of them – it can cover up to three CT clinch . For model , connecting a 2nd clamp to the end product from your solar panels give the Zappi oversight of the unripe electrical energy you ’re generating . outfit a clamp around your home storage barrage fire ’s output let the Zappi see whether it ’s muster out , so it can ensure never to charge your car by running down your battery .
You could get more from the Zappi if you also pair it with other MyEnergi products , such as the Eddi – a charge diverter that uses spare solar electrical energy to heat your hot weewee – or the Libbi battery . Because these can all colligate at once to each other and MyEnergi ’s services , they ’re capable to exchange more selective information and mix a bit more closely than if you had a mix of devices from different producer .
Core features
All new UK charger must have smart features , but the agency these are implemented – and how well they crop – can make a big conflict to the ease and toll of charging your automobile . The Zappi is one of the more fully featured EV charging points . You ’ll get the most out of it if you ’ve also got a unripened business leader source such as solar panel , but even without them it compare well to many other home chargers on the marketplace .
On its most introductory spirit level , the Zappi ’s profligate mode will charge your EV at the maximal supported charge per unit whenever it ’s connected . Potentially that ’s 7kW for the single - phase and 22kW for a three - phase Zappi , but many motorcar are restrict to 11kW or even 3.6kW when AC point . In plus , you may ‘ boost ’ appoint your car . Manual mode lets you choose an amount to provide in kilowatt hours ( kWh ) – utile if you bed your car ’s battery capacity and , for example , want to half - charge it .
you’re able to also use the programing feature article to configure a veritable degraded charge , for model if your EV duty gives you six hours of cheaper electricity each night . This is quite conciliatory , supporting different programmes for each day : some tariffs have longer off - top minute at the weekend .
MyEnergi does n’t seem to call about it , but this charger also supports flexible charge per unit tariffs such as Octopus Agile . To prepare this up you ’ll need to create a MyEnergi score online , choose your duty , and configure a Budget Charge – you ca n’t do it in the app , and it take me several weeks of ownership to discover the extra functionality . The feature lets the Zappi firm - charge your railway car when electrical energy falls below a price you set .
I found this to be great for making the most of very low plunge pricing on Octopus Agile , but there are some limitations . The duty ’s pricing runs in half - hourly time slot ground on that day ’s sweeping electricity prices . Like all other smart chargers , under government regulations the Zappi must apply a random delay of up to 10 minute to the start and end of any automatically schedule charge , to avoid the grid being overwhelmed as thou of EVs simultaneously begin or stop charging . If there ’s just a undivided half - minute slot that falls below your price threshold , you could miss out on a third of it , or rouse for up to ten minutes at the higher rate that follows . It ’s a shame you ca n’t get around this automatically , although it ’s not MyEnergi ’s fault .
The MyEnergi app does a great chore of present you what ’s going on . calculate on your configuration , its nonpayment concealment will show you the energy use in your home plate , what ’s being import from the grid , and how much is run into your car . solicit on any of the three icons bring up a more detailed view . In the vitrine of the Zappi , you ’ll see how much vitality ’s been add to the car since you plugged it in , along with a charge story graph . While this default to ‘ Today ’ , you’re able to view any single daylight , or sentence periods such as this week or last calendar month .
tapdance the primal leaf icon and you ’ll get an overall crack-up of the energy used by your base and automobile , and how much you ’ve import from the storage-battery grid . Again , visual image make it leisurely to understand , and you could change the time full point . My only critique here is that you ca n’t pick a specific week or calendar month – for lesson if you ’re interested in comparing last July with this July .
Advanced features
As I mentioned , you may get more from the Zappi if it ’s installed with other home coevals or energy direction devices . In particular , if you ’ve got home base generation the Zappi can vary its charge charge per unit right down to the 1.4kW minimum that EVs will corroborate . This means you may prioritize charging with whatever unripe energy is uncommitted , rather than taking power from the grid .
My home has 5.3kW of solar gore , and I ’ve also got MyEnergi ’s Eddi hot piss diverter . Getting the most from this setup requires a CT clamp at my family ’s connexion to the grid , with a second one on the solar yield . These state the MyEnergi system how much business leader we ’re generate , and how much we ’re taking from or exporting to the grid . The organisation also know how much powerfulness – if any – is going to the blistering water or the car , so it can act out how much the remainder of our household is using .
With this apparatus we can benefit from the off - peak and downcast - rate scenario limn above , but we also have the option to employ Eco musical mode . When there ’s less than 1.4kW of ‘ spare ’ electrical energy from our solar panels , this will charge the car at 1.4kW and take out any extra baron it needs from the grid . When there ’s more than 1.4kW fifth wheel , the Zappi increases the charge rate to use all spare solar power to tear the car .
I incline to favour the stricter Eco Plus fashion , which wo n’t charge the machine at all unless the amount of homegrown Energy Department matches the minimum multiplication level ( MGL ) you set . With this on 100 % , the Zappi will only charge when more than 1.4kW of solar vim is usable , adjusting its rate upwards when there ’s more , and stop if there ’s less . you could combine either of the Eco way with the scheduling or boost feature , to charge with a mixture of cheap off - peak electricity and complimentary solar or fart power , look what ’s uncommitted .
The system work excellently in practice , but there are a couple of point to note . The first is that Eco Plus modality can be annoying on gay Day with fast - moving swarm , as it can extend to very stop - start charging as your solar venire ’ outturn jump up and down . you’re able to smooth thing out by reducing the MGL , which lets the Zappi draw off some grid tycoon to uphold the 1.4kWh minimum . If you do n’t mind getting stuck into the on - gimmick bill of fare , you’re able to also configure farseeing postponement before charging showtime or stop consonant after the useable ability crosses the threshold .
The other is that , like other currently usable AC battery charger , the Zappi ca n’t support fomite to home plate , vehicle to grid or vehicle to loading ( collectively know as V2X ) . These scenarios have you use the energy stored in your EV ’s battery to power your home base , or trade it to the storage-battery grid . While more EVs are beginning to support V2X , the DC chargers you need to make it work are n’t yet on general sale .

Final Thoughts
The Zappi is a nicely made and well thought - through chic courser that work reliably in practice . With keep for off - peak and varying tariffs , it can aid any EV machine driver understate the cost of recharge at nursing home or the post . However , it ’s at its skilful when used together with micro - coevals , where its ability to aline its thrill rate down to 1.4kW can minimise or virtually avoid the use of grid electricity .
The Zappi is especially sympathetic if you ’re intending to grease one’s palms it alongside the MyEnergi Eddi , and possibly the Libby battery . Because they ’ll all communicate straight off , you could control exactly how they ’ll charge , discharge and amuse electricity , to help you make the most of your home generation .

The unmarried - form Zappi tops out at 7.4kW , equivalent to 7.4kWh of care every 60 minutes . Allowing for losses , that should recharge even the crowing of EV battery in no more than about 15 hour , and a more distinctive car within 10 hours . The three - stage Zappi indorse 22kW , but few cars will go above 11kW when AC charge .
