As an electrician based in Newcastle, I'm always on the lookout for products that can help my clients save on their energy bills while being environmentally conscious. I've recently come across the MyEnergi Eddi, and I have to say, I'm thoroughly impressed. Here's my detailed review of this innovative product.



For those who aren't familiar with the MyEnergi Eddi, it's a clever device that allows you to make the most of your excess ☀️ solar energy, rather than exporting it back to the grid. It works by diverting this energy to heat water in your home, which means you can use it later rather than relying on grid-supplied energy. This not only saves you money on your energy bills, but it also reduces your carbon footprint by utilising clean, renewable energy.


One of the things I appreciate most about the MyEnergi Eddi is its user-friendly design. It's easy to install, and its intuitive controls allow you to customise it to suit your energy usage patterns. This means you can optimise your energy usage and savings over time to reduce your bills.


But what sets the MyEnergi Eddi apart from other solar energy devices is its advanced algorithm that constantly monitors your energy usage and adjusts accordingly. This means that you're always using your renewable energy in the most efficient way possible, reducing your reliance on grid energy and increasing your energy savings.



I also like the MyEnergi app, which allows you to monitor your energy usage and savings from anywhere. The app provides real-time data on your solar production, energy usage, and savings, making it easy to track your progress and adjust your settings as necessary.


What is the MyEnergi Eddi?


The MyEnergi Eddi is a smart energy management system designed to help homeowners make the most of their excess solar energy. Acting as a solar power diverter, it connects between your fuse board and an immersion heater, controlling the amount of electricity flowing to your water tank. This clever device is particularly beneficial for homes with variable electricity generation from solar or wind power. By monitoring the energy flowing in and out of your home, the Eddi ensures that any excess electricity is used to heat water, thereby reducing your reliance on gas boilers and grid energy. This not only helps in cutting down your energy bills but also promotes the use of clean, renewable energy sources.


Key Features and Technical Details


The MyEnergi Eddi boasts several key features that make it an effective energy management system. It can divert surplus self-generated energy to a designated heating appliance, such as an immersion heater, storage heaters, underfloor heating, or space-saving electric heaters. Impressively, the Eddi can be configured to send energy to up to two heating appliances sequentially, giving you control over where your self-generated energy is utilized in your home. Compatible with solar or wind power and energy storage units like battery walls, the Eddi is versatile and adaptable. Its backlit LCD display, simple controls, and LED indicators make it easy to monitor and manage your energy usage, ensuring you get the most out of your renewable energy.


How the MyEnergi Eddi Works


The MyEnergi Eddi operates by detecting surplus energy generated by your solar panels or wind power and diverting it to a designated heating appliance. Utilising a sophisticated algorithm, it constantly monitors your energy usage and adjusts accordingly, ensuring that excess energy is used efficiently. The Eddi can be controlled and monitored through the MyEnergi app, which provides real-time data on solar production, energy usage, and savings. This allows you to set schedules and adjust settings to suit your energy usage patterns, making it easy to optimise your energy consumption and reduce your energy bills. With the Eddi, you can rest assured that your renewable energy is being used in the most efficient way possible.


Prioritise your solar panels consumption! ⚡️


One of the most impressive features of the Eddi is its ability to work in tandem with the other Myenergi products via integrated software. This makes controlling your surplus energy usage a breeze, as you can easily prioritise which devices are consuming the extra electricity. For example, with the Zappi set to priority mode, the surplus energy will be directed towards charging your electric vehicle before it even begins heating water in your household via the Eddi. Once the EV has reached its desired charge, the Eddi will then automatically kick in, ensuring that no surplus energy goes to waste.


As an added bonus, if you already have a Zappi installed, the Eddi’s CT clamps won’t even be necessary as the Zappi will provide all the energy monitoring information wirelessly. This means that the installation process for the Eddi is both easy and straightforward, reducing the time and cost of the process.


So, how much money can it save me on energy bills?!! 🤑


The MyEnergi Eddi works by diverting excess solar energy into your hot water tank, which means that you’re using free energy to heat your water instead of relying on your gas or electric boiler. By using the MyEnergi Eddi to manage your energy consumption, you can potentially save hundreds of pounds per year on your energy bills. This reduction in reliance on a gas boiler not only saves money but also minimises your carbon footprint by utilising renewable energy sources.



One of the key benefits of the MyEnergi Eddi is its ability to maximise the use of your excess solar energy. If you have a solar panel system installed on your home, you’re likely to generate more energy than you use during the daytime. This excess energy is usually exported back to the grid, and you receive a small payment for it under the UK export electric tariff. However, this payment is typically only a few pence per kilowatt-hour, which means that you’re not getting the full value of your excess energy.


By using the MyEnergi Eddi to divert your excess energy into your hot water tank, you can potentially save much more money than you would by exporting it back to the grid. According to MyEnergi, you can save up to 50% on your hot water heating costs by using the Eddi to manage your energy consumption.


To put this into perspective, let’s say that you have a 3kW solar panel system installed on your home, and you generate 10kWh of excess energy per day. If you export this energy back to the grid, you’ll receive a payment of around £0.05 per kWh, which works out to be a daily payment of £0.50. However, if you use the MyEnergi Eddi to divert this energy into your hot water tank, you can potentially save up to £2.50 per day on your energy bills, which works out to be a saving of around £900 per year.


Of course, the actual savings that you can make with the MyEnergi Eddi will depend on a range of factors, such as the size of your solar panel system, your hot water usage, and the cost of your energy tariffs. However, based on the figures provided by MyEnergi, it’s clear that the potential savings are significant.
