Thank you for having us FullyCharged Team, always great to work with you.

I am looking at getting one of these but I can’t see how they can lead to any savings? My off-peak go tariff is 7.5p kWh. My gas is 7p kWh. So if I was to heat my hot water cylinder up at 00:30-04:30 it would cost me extra to do so. Likewise, if I divert my excess solar to an Eddi, I will save 7p kWh gas but as I am on the a SEG tariff I will not be getting the 4p kWh for exporting the excess solar. So I am really only saving 3p kWh. At £500 supplied and fitted that is a lot of 3p’s to see a return. It might have worked great with FIT payments but not now, Or am I missing something?

Just had one of these installed. I have 2 x Solar systems. A legacy solar system (came with the house, 16 panels), and a spanking new one (38 panels). The Eddi can handle both (2 x harvi sensors), and manage hot water based on a surplus of power measured against the combined output of both (separate) solar systems.. rather impressed.! I also have a 19kwh battery - Eddi allows battery to be prioritised before taking power to heat water - another excellent feature... really good product.

I've got an Eddi and use it as described to heat water from my solar PV from spring to autumn, allowing me to turn my gas boiler off for half of the year. I'm intending to invest in a home battery and will also be getting an EV next year. So my hope is that on sunny days I'll be able to charge my car; heat my water and use whatever energy is left to charge my home battery.
I reckon this will minimise both the amount of energy I draw from the grid and the amount I send back, reducing my energy costs and my carbon footprint. A win-win!

[johntisbury]

Love the myenergi products, we have them all! The support and backup is excellent too. An example of a great UK company.

[abrahamgalvez]

ABSOLUTELY love the work by the FullyCharged team. Please keep up the fantastic content!

[grahamt]

I had an Immersun installed around 5 years ago, and every summer I switch of my boiler and get all of our hot water heated by the surplus electricity from the solar panels. This sounds like a next generation of one of those. It was a great investment.

[smikedenney]

Can I use it to solely use it to charge an Anker power station?
Thanks

I love the products for the home that I am seeing here. I would like those featured to be asked if and when their products will be made available outside of the UK. I live in the USA and I am sure many others in the EU would be interested as well. Thanks and great show!

[rugbygirlsdadg]

What we need is something which understands not just your car's state of charge and the temperature of your hot water, but the state of your household battery and your tou tariff and can use off peak electricity as well as excess solar.

[JustfishNascar]

I'd be really interested to see this in the US. I spoke to Jordan at Fully Charged USA about this product. I hope it will be available soon.

[nicwesthuizen]

Where I stay grid export is not allowed. I want to use an Eddi to warm my immersion water heater but can not see how the Eddi CT clamp will not interfere with the export limiter CT clamp. I use a Solis Grid tie inverter with CT clamp for zero export thus wasting large amounts of power daily. Is there any inverter with a integrated hot water power diverter? How does the Eddi work on a off grid inverter?

[Dvearncombe]

I love the concept, although the business case doesn’t appear to stack up. It looks like I get 3x the cost of Gas if I export my excess solar power (15p/kWh). So I’d be better off selling my excess solar as export and then buy gas to heat my water. Or have I got this wrong?

[nc]

Great but it should take into account the price your paying and earning. To decide whats best use for the surplus electric

[philipbroggio]

Eddi takes up the solar less than 1.2 kW and Zappi on ECO+ takes the surplus above up to my peak of 3.5 kW. Works perfectly to get self usage up to Max .

[tonykelpie]

We have an EDDI and 6.3kW solar panels. Has eliminated use of gas for water and house heating over last 12 months. One small negative- the unit is high on a wall and difficult to read as the screen is small and grey. A larger screen would help

[TonyMontana-osri]

Is it working with tap hot water only or can be used for heating radiators too?

[frejaresund]

I have been enjoyed, so thank you for delivering.

[robertsmuggles]

Can I use this to store *all* the energy my pv generates? My idea is to install a small solar panel on the wall - just to provide a modest amount of free hot water during the summer when my gas boiler is off. Or am I being unrealistic ? thanks (single person household).

[stevieg]

If you have your central heating circulating pump separate to your boiler would you still be able to use your heating despite the boiler being switched off through the spring to autumn period. Meaning the Eddie would be doing the heating of the water as opposed to the boiler and the central heating pump circulates the hot water via the three port valve through your radiators?
