Frequently asked questions

How far can an electric car go on a single charge?
Vehicle range is the estimated distance that your vehicle can travel on a single charge. In terms of electric vehicles, this refers to the amount of charge left in the vehicle battery at any given time. This is often displayed on a vehicle dashboard as either a percentage or miles/KM remaining. A vehicle’s actual range depends on many fluctuating factors, such as the environment and your personal driving and charging habits. See how far your EV can go in our handy guide >>
How long does an electric car take to charge?
This depends on the size of the vehicle battery in kW and the rate of the charge in kWh. Based on an average 54kWh battery, a 50kWh public charger would take around 64 minutes to achieve a full 100% charge, whereas a typical 7kWh home charger would take around 7hrs 42 minutes.

What electric cars are capability with zappi?
Our zappi is for sale with two different connectors: Type 1 and Type 2. This means that almost every EV is compatible and can be loaded with zappi. Explore the ever-growing EV compatible list >>
How can I get a car charger installed at home?
There are two main types of EV charging station: fast charging for homes, and rapid charging for public chargers. Most home electric car chargers use AC charging: however when rapid charging is required – for instance, at motorway service stations – DC charging is typically used as it is quicker. We are seeing a rapid increase in the number of charging stations at UK & Irish workplaces – particularly from companies that have electric fleets. Charging at work is becoming an increasingly popular facility – and many businesses are utilising the government’s Workplace Charging Scheme (WCS), which is a voucher-based option that provides financial incentives for installing EV chargers.

How much does it cost to charge an electric car at home?
Based on 54kWh, the average cost to fully charge an electric car from empty to full is around €9.10 whilst the average monthly cost to keep an EV charged would be around €36.00. This data is based on fully charging your EV once per week at home. Another advantage is that EV’s are also exempt from paying Road Tax and are significantly cheaper to maintain.

What is a type 1 electric car charger?
Type 1 electric car charging is a 5-pin design that comes with a tether to prevent it from being pulled out of the charging port. This type of charging point is the dominant variation in Asian, Japanese and American markets. It is less commonly seen in Ireland, UK and mainland Europe. Type 1 chargers only adds about 4 miles of Range Per Hour (RPH), depending on the car’s make and model. So it often referred to as slow or emergency charging in Ireland. A Type 1 charger is commonly misdescribed as the standard 3-pin sockets we have everywhere in Ireland, this is a 3-Pin charger, not a Type 1 electric car charger.
What is a type 2 electric car charger?
The Type 2 car charger is typical of most chargers found in Ireland, UK and mainland Europe. Type 2 models are known as such for their 7-pin design don’t have these latches. Instead to hold them securely to the vehicles, they utilise a locking pin that locates and secures the plug in place. This type of charger will provide your EV with about 25 miles of Range Per Hour (RPH), but can also offer different charging speeds for example eco or fast.
Why won’t my car charge/eddi heat despite having plenty of surplus energy?
Check that your grid CT is fitted and configured in your zappi/eddi (please see CT golden rules)
Which zappi do I need if my EV uses a type 1 connection?
If your EV uses the ‘Type 1’ connection, then you will need to purchase an ‘Untethered’ zappi which can be used with all Type 1 & 2 compatible vehicles using your own charge lead.
What does a red zappi, eddi or harvi light on the hub indicate?
This indicates a loss of communication between the hub and whatever device is displaying the red LED.
Can the CT cable be extended? Is there a max length?
Yes! You can extend them up to a maximum of 100m but you MUST use a twisted pair cable (cat5) for it to work and maintain correct polarity throughout.
Do I have to have a CT fitted to the solar PV feed or not?
Providing the ‘Grid’ CT is fitted then zappi/eddi will work perfectly. The solar PV CT isn’t compulsory, but it does give you your solar PV information on the zappi/eddi screen and also on the app giving you one place to view everything.
There are no histories showing in the app, though real time data is fine
Please check the Time/Date settings are correct on every myenergi device. On the Time/Date menu, check • The Timezone is correct • Auto DST is turned ON • Update from Cloud is turned ON (if paired with a hub)
Do I need a harvi?
Only if you can’t hardwire any, or all of your CT’s back to zappi or eddi units. Harvi will transmit CT data this wirelessly (subject to distance and certain obstructions)
Does the zappi require any RCD protection?
No! The zappi 2 has an A-Type RCD with 6mA DC leakage protection built in meaning no requirement to fit an RCD elsewhere
What distance can the wireless comms on the harvi or hub reach?
We usually recommend no more than around 20-25m although in a lot of cases this can be much further. Each site needs to be assessed on an individual basis for anything that could obstruct or disturb radio communications.
What does a red server LED on the hub indicate?
A red server light means that the hub is not receiving any data from the server. Check that the hub has an Ethernet cable to your router and that this cable is working OK by plugging in another device such as a computer. (You should also try rebooting your router and the hub)
What does a red zappi, eddi or harvi light on the hub indicate?
This indicates a loss of communication between the hub and whatever device is displaying the red LED.
