Hi,

Up to now, I thought Combi boilers did not use a copper tank. Seems I was wrong, so please ignore that comment. As long as you have a copper tank, you can use an Eddi.

Out of curiosity, does your combi boiler feed your copper tank, or is it separate?

I like to learn stuff!!

@BoxerX Depending on the size of your battery (if you have a battery), you could possibly have boosted the water temperature with the Eddi rather than using the Gas, if the day was likely to fill the battery anyway, and also assuming it has charge remaining.

@fuse I have a Combi, and the very function of a Combi is to instantaneously heat water on demand, off the rising main, sending it straight to the taps.

I have a sort of hybrid system in that I have 30 Kingspan tubes, connected to a 160litre tank (which has an immersion rod in it too). The output of this feeds an Intrsol Combi Mixing Valve, and sends water directly to the taps if over 48°C, or else to the input of the Combi, for heating to 48°C

I believe my setup is very much the exception for Combi's

Thats not great tbh.

A few things, the Huawei gear is good but over priced. Is the Huawei inverter battery ready, you are limited to Huawei batteries with it.

Something like the Solis hybrid inverter is less expensive but a solid unit that accepts various batteries and self build batteries.

Do you need 12 optimizers?

Hard to know without the specifics of make/model of inverter. I can think of some scenarios (around vMax input) on a single string which is 600v and you'd need to have a dual string inverter to go above 13 panels......but I'm speculating a little.

I don't think you are being fleeced though as that 16 panel price is fairly competitive.

Thanks, I've queried the Solis inverter which they can supply so I'll get an updated quote next week.

I've attached a picture of the roof showing the shading at 11:30 in early May. The only shaded area is the lower right hand corner so possibly only 1 optimiser would be required? This roof was still in sun until 7pm on the same day.

Battery not included, looks like my quote is a bit high.

I have about 4-5 quotes so far and none of them are coming in with a great price tbh

Getting my ground mounted system installed next week. Will let you know how it went. I went with a 9.1kw system in the end.

20 Ja Solar 455W instead of the 22 Ja Solar 370kw ones. The 455 W ones are silver edged on the sides, but as I am installing a ground mounted system this isn't an issue.

I am getting a: 9.1kw ground mounted system with a BER rating included, wifi dongle, 6kw Solis inverter all ground works included for a brilliant 7645 euro after the grant

Will keep you posted how it went.

Will be getting an ev in the next year. Huge electric usage as 5 in the household with 3 at home all day WFH.

I hear you championc. It's just that I am getting such a ggod price I can't refuse it. Down the road I can add a battery or perhaps I'll have 2 ev's in the house. Go big with the panels at installation was my thinking.

That's a great price.

I've seen quotes for a third the size for a lot more

Thanks for that DC999. Will let ye know how it all goes next week. All I need now, is for the sun to shine. 😁

Yep, sounds like you are buying the scaffolding with the kit :)

Would love to see the ground mount. I have to go this route myself due to roof shape.

Very similar set up here with work from home, someone is here all day with heavy use. I'm using over 9500 kw a year. Most of that is day time use as we are gone to bed by 9 🤣

Hello,

I am live since last week and can only recommend to every one thinking about it to go ahead.

I have the following:

18 x 400W Trina panels

1x Hybrid inverter Sofar 6KW

3x 2.4KWH Dyness batteries including cabinet

1x Zappi car charger

Cost in total around 13500 Euro before grant. I know there is a shortage with everything and prices are going up (might come down again). EV is on order and even so I am sitting in the wet west, the system is kicking out plenty of juice. I am sure it will be different in winter, but it will make my A2 rated house into A1. And I am helping the planet as well.

Well done @DieterDicht

Nice system and a good price. I presume your EV is going to be home during daylight hours?
