-Solis Hybrid inverter 5kw to future proof extra panels later date and wifi dongle for inverter app
-4.8KW battery
-14 panels JA solar 330w on a west facing roof
-Eddi water heater for immersion
-Zappi 2 car charger untethered and myenergie hub
Fair bit of shading due to trees so hope to lash more panels on east roof and maybe ground mount south facing later .
7000e after grant - cost to me.
That is just amazing!
What were/are your electricity bills - please include your bill frequency if possible. We're paying about 154 per month with the heavily discounted energia plan. We have no ev at the moment, but will definitely want to go down the road of an Eddi
How has the Eddi been? I will be getting a 300l cylinder in soon, replacing my old tiny cylinder. I am hoping the Eddi will sort out most of my dhw needs. 2-3 showers per day (long shower lovers in this house)0 -

Payback/Savings have been discussed in the monthly stats thread, but going on bills alone can be misleading (due to a better knowledge of energy use, heavily discounted energia rates, etc)
eg, from my system in feburary (Remember, just coming out of dark winter) I "saved" €19 from the solar power used directly, and battery (capturing excess) saved €9. Only have 2 months under my belt yet so Looking forward to the summer.
As for the eddi, if there is a battery in the system, this time of year very little if any will be going into it.
My dad's system doesnt have any (5.6kwp) and in march so far, 34kwh has went into the hot water tank, which would heat 600l of water up by 50C.
some days nothing goes into it, good days (end of feb), 5-7kw went in.
I assume you have another way of heating your DHW? oil/gas?
as your getting a new tank in, will you be able to have that independently control your oil/gas and only heat hot water when needed (ie the heat for the rest of the house doesn't need to be on to heat your hot water)0 -

I had a Grant vortex installed just two years ago. At the same time, I got the whole system zoned, and everything is now controlled by an app called Alarm.com via a company based in Cork. Excellent system, and amazing benefits all round. I now spend much less per year in terms of oil fills, but have greater comfort.
I would be delighted to make the savings in the summer more so than the winter. I would like to think that I would save something on my oil through the year

My bills vary from ~200euro bi-monthly in winter (Nov-Feb) to 80euro or less in summer. Vast majority of that 80 euro is the service charges.
Very happy with my Eddi. In winter I have the boiler on going through 300l twin coil tank anyway so don't need it. In the last week it's just started getting enough extra power (Monday for instance I got 21kw total, >8kw went to the Eddi and brought the water up to ~65C) to start using = just as the boiler starts to be used less.
Come summer, boiler won't need to be used at all for the hot water tank - bar the odd sequence of days that we could have consistent dark clouds.
Other good use I get from the Eddi is I have the relay board fitted and two RTD's so at any time I can check the tank upper and lower temps and decide if it needs a wee boost. Can be boosted then from the mobile phone. (Handy on the mornings I don't want to get out of the bed until there's water for the shower ) .
I would say 2-3long showers a day might be pushing it for the solar depending on size of battery and base load of house, even a full 300l tank will struggle with that if they are all at the same time or directly one after another. TBH, I tend to have them in the evening and herself in the morning so not sure exactly how it would work.
PM me if you need any extra detail.0 -

Thank you for the info
When I said long showers, I meant about 5 mins most days before work - and an odd day when I'd be closer to 10 mins. If the shower is being used one after the other, we're either off out somewhere or in a hurry to do something - so that would be the shorter showers.0 -

Me and you have differing definition of long showers My after cycle showers are 20mins - sore muscles appreciate a good soak in a serious power shower!
5 mins x 3 would be no issue with a full 300l tank. One thing to note though is it's amazing how much water stratifies in a tank. I often see top temp at 58C and the bottom at 20C. Without being able to see that i would say you could easily end up with the third shower being a bit cool 0 -

As others have said the EDDI will do very little Nov-Feb, if you get a good day outside that then it can easily put a lot to hot water but this totally depends on your house load, battery levels, your potential generation and hot water usage.
I can see my Eddi taking 1-3 kW a day here and there but this can be made up of streaks of 100-200w etc which in reality can’t be heating the water to a great extent.
I’d say you’d need a good 1.5kW+ to truly heat water in a meaningful manner.
EDDI is quite straightforward so a self install if you want to keep costs down.My stuff on Adverts, mostly Tesla Pre Highland Model 3

If you have a South facing shadeless roof then just fill her up, I don't know why you need an engineer though, just a solar installer.
If you are not at home then there will be less electricity in use but this depends on your usage pattern, we currently have four at home but our base load is currently 400-500w and that's two PCs and two laptops as well as lights, fridge, freezer etc.
If you are at home then the only real impact will be anything with an element e.g. oven/shower/dryer/washing machine etc and the majority of these should be on during night rate.
The weather has a huge part also, yesterday was gloomy from the word go so our generation was 2.8kWh with nothing to hot water, on March 1st I put 9kWh into the water as it was a great day...
some companies use the term "engineer" for a pre-install inspection.
I remember eir used it to describe their installers. No more an engineer than I am, and I work in the tech sector
