Thanks for the response. If it's the company I think you mean, i did get a quote from them but they actually quoted SAJ and Anker systems but I didn't think the price was overly competitive so didn't actually get a sigenergy quote. The sig quote above came from a Tipperary company. On the gateway they said they could start to install almost imminently.

Anyone here concerned with the heat of inverters/batteries inside the house.

I've mine in the shed & on full production there is some heat off the inverter.

One of the reasons I went outside with it...I had the option to do so so nothing extra to me

I am trying to decide whether to add a battery and an EDDI to a solar design. My question is - will adding an EDDI improve the BER figures? Will adding a battery affect the BER figures? Will adding a larger battery be even better for the BER? I need to get to B3 form C3 and every little bit helps!

No, eddi or battery won't effect the Ber at all

Aren’t they banned from installing batteries in attics in the UK?

Hello,
could i get some feedback on this quote please its on the higher side but 20kw of battery storage:

Battery System (Alpha)
10.12kWp of modules kitted to an Alpha ESS Smile 5 Inverter and 2 x 10.1kWh Batteries

22 x REC Premium 460W Monocrystalline Pure-RX modules (all black modules)
Fire Safety Switching
AC Switchgear
Alpha ESS Smile 5 Inverter
2 x Alpha ESS 10.1kWh Batteries (20.2kWh of Battery Storage)

Costing
€16,200

PV changeover switch is an extra 700 euro so all coming close to 17k in total and no grant.

Thanks.

ignoring all the sundries and standard equipment you are getting a 10 panel system and eddi for 6.5k after the grant

I posted earlier that I’m getting a 14 panel system for less than 4k. Rey the company I listed earlier.

Hi Folks,

Have two quotes for a ground mount system. BER and grant included.

Quote 1: 9.68kW Solar system with 10kWh battery storage

Inverter - Solis S5-EH1P5K-L

Panels - 16x Jinko Solar Tiger Neo (605W)

Battery - Dyness DL5.0C

€11,700

Quote2 : 9.84kW Solar system with 10kWh battery storage

Inverter - ANKER Anker SOLIX X1

Panels - 16x DAS Solar Bifacial Double Glass Module (615w)

Battery - ANKER X1-B5-H

€14,750

What are your thoughts on quotes overall. David Hunt is good on both but better on the first one naturally.

I'm getting it hard to justify the Anker premium. Solis at this game a while I think this is Anker's first one - it a nice looking unit in fairness. It has some future proof features (auto changeover - when available , Virtual Power Plant support - when available, Dynamic tariffs)

Green&Red · 17-06-2025 11:23AM

Anyone with experience of Planet Blue?

€14k quote for 9.79kW solar & 10kW battery install on new build.

Buffman · 24-06-2025 11:14PM

I was chatting a lad the other day who was charged an extra €400 by an installer for the removal of their pre-existing 4x250W micro-inverter solar PV system as part of a new installation.

From what I saw of the leftovers all they did was cut the main AC cable in the attic and plonked everything else in a pile in the garden. Nice money for a few minutes work!

Lord Spence · 25-06-2025 11:11AM

Hi All,

Got my first quote any thoughts?

20/22panels ground mount . Anchor or screw mount . If you could put your thoughts . Tempted to go cheap and replace later when technology is better . Other option is buy better now and hope they last 10 plus years or more.

The only concern is the large deposit in advance, 75% of the full cost, paid by bank transfer. Grant is also up to you, they'll provide the paperwork, you've to get BER. Still very competitive, I might go with them.

ted1 · 02-07-2025 05:18PM

https://www.boards.ie/discussion/comment/123599310#Comment_123599310

I’d recommend them. Up and running for just a week now. No issues with the deposit. They are around long enough as opposed to all the newer companies

Sponsorgate · 10-07-2025 07:34PM

Hi All,

Been shopping around and this is the most competitive quote. This is a good quote yeah?

9.79kw size system with 20kwh batteries

22 X TW 445kw panels (BDB)
1 X 5 kwh SIGENERGY Inverter
2 X 10kwh SIGENERGY Batteries (New size)
BER Assesement included
ALL other materials, testing, commissioning, paperwork for grant included

14600 - 1800 =12,800

Thanks

That seems really good from what I've seen. The batteries alone are nearly 3k each, my current favored quote can't compete.

Who was that with? I think I need to get a quote from them.

farmerval · 11-07-2025 10:01PM

Hi Folks,

I find this stuff quite daunting. Had one supplier give me a quote, it was high, but the bigger issue is some of tehstuff he said;

a. battery is on the DC side of the invertor, and can only discharge at 3.5KW per hour.

b. That the invertor can only deal with 5 KW /hr regardless of how much your panels are generating.

c. If you are charging an EV the rate of charge is regulated by the invertor, so a large EV say 70KW would take two days to charge?

Is this stuff right? I would be ideally looking at 14 panels, 10KW battery and any excess possibly to a future ev

con747 · 11-07-2025 10:10PM

https://www.boards.ie/discussion/comment/123625985#Comment_123625985

No, get another quote off someone who know's what they are talking about. The tech lads here can explain why he's full of BS.

deezell · 12-07-2025 06:58AM

https://www.boards.ie/discussion/comment/123625985#Comment_123625985

a. Possibly true, depends on the inverter, and advised discharge rate from the battery. Nonetheless, the inverter should still be capable of sending at a rate of 5kw to the grid if the panels are also generating.

b. True, though it may be capable of sending to the battery simultaneously. With 14 panels, nominal 450w say, your max is 6.3 kw, but only on the sunniest days around midday.

c. No. Your EV charger is just connected to your house main. It will consume grid and inverter power together to its maximum. If the charger is rated 11kw, and your car is rated to take this,it will, but from the 220v mains generally 7kw is the limit. Over ten hours to fill a fully depleted 70kwh ev battery, though they're never allowed to bottom out, and the last 10 kwh of charge is at a much slower rate. You'd need a commercial mains connection for a fast charger, and that's an expensive prospect. 22kw charging rate would require a 100A connection from single phase domestic connection, and that's with no other load on the system. Your domestic load is generally 63 amps max.

Best ev chaging scenario is night rate aided by a filled solar battery, but most really cheap ev rates are only for a few hours afaik. The problem with cheap smart night rates is the punitive day rate. You might have to charge you car fully on day rate mostly from time to time and on dull winter low solar days, or at a charging station, which can cost as much or more to run as petrol, but thats the reality, there's no such thing as a free lunch.

B)

Sorta, only 5kW can leave the inverter, but there is an edge case most inverters can output 5kW to AC and then also charge the battery, but the battery in this case needs to have room in it for the extra power.

Aquos76 · 14-07-2025 09:56AM

I've had a couple of quotes for a PV system over the last few weeks, the dearest by far was from a company with"8" in its name who kept going on about how good their panels were compared to everyone else and how their software is AI based now when it comes to charging the batteries, I honestly don't know enough about these to know if what they were welling me is true or not.

Anyway, I am close to going with another company, I am based in Waterford City and its an East/West system I will be installing, this is the system they have quoted me for, its a 7.120kW system, Would someone mind throwing their eyes over the components and telling me if they are decent or could I do slightly better?

Solid enough quote that - nothing really wrong with it. I'd probably drop the Eddi though possibly and save yourself €600.

With todays tariffs, it's hard to see it paying for itself (even in 5-10 years). That said, I do have one myself which was purchased before the feed-in-tariffs were a thing and I'd buy one again as I like the fact that I consume as much as my own power as I produce, but as for a return on investment it's not a good buy. You can achieve 90% of the same functionality as an Eddi with €50 from Amazon.

conf101 · 15-07-2025 02:57PM

Had a survey today with a guy who essentially advised against a battery. They have an offer at the moment that includes a free 5Kw battery with 12 or more panels (which I'll be getting). He said there's definitely no need for any more battery space and if it wasn't free with the panels, he'd be advising me against getting a battery at all.

For context, my annual usage is approx. 3,500 Kw per year and I'm looking at getting 13 panels, so ~5.7kw system.

His advice is contrary to everything else I've read or been told. Does he have a point?

graememk · 15-07-2025 05:12PM

https://www.boards.ie/discussion/comment/123638197#Comment_123638197

Nothing is "free" Its built into the price. Get more quotes, and what is the quote that your getting?

But with export rates at what they are, The payback for batteries isnt from solar, its from load shifting power use from day rate to night rate.

conf101 · 15-07-2025 05:34PM

https://www.boards.ie/discussion/comment/123638687#Comment_123638687

Oh for sure. I'm getting a whole bunch of quotes. This one was €7217 (after grant) for 12 panels, Solis inverter, and 5kw battery (that's included "for free").
