Reclaim Your Solar Power. Cut Your Costs.
If you have already made the leap into solar, you are on the right track. But here is the snag: without a diversion system, a good chunk of that energy is being sent straight back to the grid for pennies. Meanwhile, you are still paying to heat your water or run your heat pump during peak-rate hours.
Myenergi Eddi solar diverter changes the game. It quietly picks up on any surplus solar energy and sends it where it is needed - typically your immersion heater or underfloor heating. No buttons to press. No schedules to remember. Just lower bills, less reliance on the grid and a home that feels smarter - and warmer.
At GreenR Renewables, we install these systems with care and engineering know-how. We are not a national chain or sales-first operation - just a Cornish team that takes real pride in helping you get the best from your home energy setup.
What You Get With Our Renewable Energy Diversion Setup
We offer a full service, not just a box and a bill. We start with your home, your goals, and your existing system. Then we design a solution that makes sense for all three.
Your install typically includes:
A Myenergi Eddi solar diverter unit
Professionally installed, cleanly wired, and built to integrate smoothly with your existing solar PV
Tariff-aware water diverters
Programmable to heat water when grid prices dip
A system review
We’ll check your setup, advise on best placement, and flag any wiring tweaks you might need
Smart app setup
So you can see what’s happening in real time, whether you're checking your energy use or just want the satisfaction of watching free hot water tick up
Load control
Fits your home - immersion heater, towel rails, or even your underfloor loop if needed
Installation by local engineers
Who’ve seen the inside of more Cornish plant rooms than we can count
Optional extras? Absolutely - if they make sense for your setup:
- EV charging that uses spare solar
- Annual performance check-ups
- Solar panel cleaning, if yours are hard to access
- System designs that leave room for batteries later
We’ve fitted systems in homes across Bude, Padstow, Wadebridge, Bodmin and plenty of villages in between. If your place has solar and space for a cylinder, we’ll help you make the most of it.
Here's how the process goes:
We have a quick chat.
It could be a site visit or just a friendly phone call. We learn what you're running and what you’d like to achieve.
We check your system.
A few checks, a bit of planning, and a clear quote.
Installation day.
Most are done in less than a day.
You start using more of your own power.
That simple. You will see it happening, especially on sunny days.
Energy Diversion Testimonials
"Cai and Richard, at GreenR Renewables are amazing! I had a heat pump and solar panels installed with an EDDI. They talked through everything, so that even I could understand the technology and its every day usage. The savings I'm making through the solar instalation is great and how they set it up for the solar to help with the running of the heat pump saves so much money to! It was really nice to work and support a small local company, where you really felt part of the project."

Energy Diversion & Eddi Servicing
If your Eddi or solar diverter isn’t working as expected, it could be wasting valuable solar energy.
We offer targeted Eddi diverter troubleshooting and general energy diversion system checks to get things flowing correctly again. From tuning settings to software updates, we help optimise how surplus energy is directed - whether it is to your hot water tank, EV charger, or battery. A well-maintained diverter means lower bills, and a smarter, more efficient home.
- What People Often Ask
-
Is this better than getting a battery?
Different tools, different jobs. A diverter is cheaper, simpler, and brilliant for hot water. If you’re heating a tank daily, it’ll pay for itself quickly.
Can I still export to the grid?
Yes. It only diverts what's left over after the rest of your house has taken its share.
Does it need an app?
Not at all. But if you’re the curious type, the app gives you a great window into what’s going on.
Will it work with my existing PV?
Almost certainly - we’ll double-check in our initial assessment, but Eddi works with most modern setups.
Can I use it for more than hot water?
Absolutely. We can set it to feed towel rails, underfloor heating, or other resistive loads - it’s all about how your home is wired.
Will it work with my heat pump setup?
Almost certainly – especially if you’ve got a hot water cylinder or buffer tank. We’ll assess it as part of the quote.
Can I programme it to use off-peak electricity too?
Yes – especially with tariff-aware diverters, which we can configure for Agile-style or Economy 7 pricing.
