HEy Everyone,

Does anyone know any installers that are doing Deye or Sunsynk invertors ? Looking for a 12 panel system with one of them if possible, cant seem to find anyone that does them though.

Thanks

This Sigenstore inverter is a combined BMS and Inverter, with capacity for a main and back up circuit, to give you cover for power outages. See if this configuration is included in your quote, as it would require a certain amount of circuit splitting in your consumer unit, e.g, lights, bed/reception room socket ring, other sockets up to the backup capacity. It would be remiss not to have this on such a large system.

You need to purchase Sigenergy gateway for this?

https://www.boards.ie/discussion/comment/123227896#Comment_123227896

Perhaps, or possibly needs two seperate inverter units, if you study the diagram. There are different devices under the B key. Installers best to answer this, no doubt a big €€ extra. This Sungrow Inverter can do 5Kw to grid, 2 to backup circuit and 2 to batteries iirc, giving a very useful essentials power cut cover, lights, tvs, Internet, fridge, boiler motors etc.

Main inverter or double inverter options

One of my quotes was for the Sigenergy Gateway, but then I was told there was a hold on the gateway as safe electric and others havent approved this for use in Ireland. Anyone hear this?

I'd seen this Oz video on them, something to do with batteries and approval

the sales rep said they were allowed to install the gateway etc and then after a few months were told to stop. Said was concerns about the gateway correctly cutting the ESB connection during power outages to avoid back feeding the main lines. (even though its used elsewhere in EU)

Now this is the words from a sales rep so im trying to find more info.

helimachoptor

hi folks, I had another provided out to quote.

He says next year the regs will change and all batteries must be stored outside, is this correct?
I'd assume most batteries currently are stored inside?

Quote today was for Denim Glass-on-Glass panels, with SolarEdge, what are folks view of the european Vs Asian equipment?

Here's a section from PAS 63100:2024, published March 2024. We tend to follow the British.

TLDR: the British regs say batteries SHOULD be outside, but not MUST be outside. 6.55 has a list of places they MUST not be. Lofts and roof spaces would cover a good amount of people with inverters

6.5 Protection against fire

6.5.1 Where practicable, storage batteries shall be installed outdoors.

Where it is not practicable to install storage batteries outdoors, batteries shall only be installed indoors at a location:

a) not precluded by 6.5.5;

b) with ventilation according to 6.5.4; and

c) with fire resisting separation where required by 6.5.3.

NOTE Outdoors can be an out building not intended for habitation that is detached or separated bymain wall with a minimum fire performance of REI 120 to BS EN 13501.

6.5.2

Where a battery energy storage system (BESS) is installed on the external wall of the building it shall not compromise the fire performance of the external wall. Service penetrations shall be adequately fire stopped and internal combustible substrates shall not become exposed by the installation.

Where wall cavities exist, cavity barriers shall be provided for services passing through the wall.

NOTE In certain cases, equipment mounted on an external wall could require planning consent,and/or be notifiable in accordance with local authority building control procedures.

6.5.3 Any indoor location in which storage batteries or storage battery enclosures are installed shall have fire-resisting separation from indoor locations identified in 6.5.5 by walls, ceilings and floors with a fire performance of at least REI 30 to BS EN 13501 series (30 min to BS 476 series for loadbearing capacity, integrity and insulation).

NOTE 1 As per Building Regulations Approved Documents in England and Wales, and Scottish BuildingTechnical Handbooks, all services passing through the fire resisting enclosure where a storage battery or storage battery enclosure are installed should be adequately fire stopped to maintain the fire resisting separation. See also Regulation 527.2 of BS 7671.

NOTE 2 Fire compartmentation requirements might need to be assessed in future editions of this standard, as there are currently gaps in the knowledge of how fire compartmentation resists lithium battery fires.

6.5.4 All indoor locations which contain storage batteries shall have fresh-air ventilation to outdoors.Ventilation systems for the location shall not compromise the fire resistance of the enclosure. The edges of outdoor port for such ventilation shall be at least 1 m from the edges of:a) doors;b) windows; orc) ventilation ports for other locations.

NOTE 1 Guidance on and further requirements for ventilation are provided in BS EN IEC 62485 series.

NOTE 2 Air tightness requirements for dwellings might preclude batteries being installed in habitableparts off a dwelling.

6.5.5 Batteries shall not be installed in any of the following locations:

a) rooms in which persons are intended to sleep;

b) routes used as a means of escape that are not defined as protected escape routes, including, staircases and corridors;

c) corridors, shafts, stairs or lobbies of protected escape routes;

d) firefighting lobbies, shafts or staircases;

e) storage cupboards, enclosures or spaces opening into rooms in which persons are intended to sleep;

f) outdoors (ground-mounted or wall-mounted in a suitable enclosure) within 1 m of:

1) escape routes;

2) doors;

3) windows; or

4) ventilation ports.

g) voids, roof spaces or lofts;

h) within 2 m of stored flammable materials and fuel storage tanks or cylinders; and

i) cellars or basements that have no access to the outside of the building.

Hi all,

My system is

System size: 6 kW Total Solar Power

4452 kWh per year

12 Panels x 500 watts

BER

Sigen energy controller single phase 5kW of inverter power

Net price 6640

Grant 2100 as I applied in December

Seems decent?

Any opinions appreciated.

4200 per annum use, house busy during daytime.

Gas heating and electric showers.

No EV

I decided against the battery in the meantime due to cost.

New to the solar game. Have been getting in quotes for a system on a roof with multiple aspects

Option 1:

16 Jinko 440W panels + 16 optimisers + 5KW Huawei inverter +14 KW (2x7KW) Huawei Batteries +SEAI

€14,550 after grant

Option 2:

16 JA Solar 445W + 10 optimisers + 5KW Solis inverter + 15KW Dyness (3 X powerdepot H5B)

SEAI Not included

€11,300 after grant

Huawei batteries come with 15yrs (12,000 cycle) warranty and 100% depth of discharge as opposed to the 10yr (6000 cycle) warranty and 90% depth of discharge

Not sure that warrants a €2,950 difference (If you allow €300 for SEAI)

Would appreciate others thoughts

Hi all,

We have got a couple of quotes that all look great using davidhunt.ie/solar quote advisor (which I'm not sure is still the benchmark based on the last time I looked).

It seems to be all down to the equipment provided, so I could do with some advice from this group if that's OK?

Option 1: 9.79KW system, 22 Aiko Neostar 445w Solid Black Panels – 5 kw Solis Inverter – 10kw of Dyness Battery - €12,500

Option 2: 9.79KW system, 22 Aiko Neostar 445w Solid Black Panels – 5 kw Anker Solix Inverter – 10kw of Anker Solix Battery - €14,500

Option 3: 10.44KW system, 24 Jinko Solar Panels 435W - 5kW Hybrid Inverter H System - Huawei Luna 2000 10kWh Battery - €14,300

So Dyness seems like the budget option, and then it's down to Anker vs Huawei if that's not recommended (and different providers for both those options).

Can anyone advise? Thanks!!

deezell

Panel prices have dropped substantially, batteries too, and solar installers are not out the door with work anymore according to a recent installer TV interview on an RTE show, so maybe labour charges have to be more realistic. This will be reflected in quotes, but not in the simplistic calculator unless someone updates the handful of price constants used in its calculation. It's not that many years ago that a bog standard installation of 8 panels and a basic inverter would run to €8000 after grant, such was the gouging going on. Let's see what the shocks of the Trump tariff slump produces, most likely more big cuts in materials.

ahshots

Yeah definitely feels like if all the quotes are coming in as massively discounted compared to the calculator, that becomes a calculator problem 😅

Great point on the tariffs too.

Of those three brands of technologies, do you see any real red flags? Should we be going for the cheapest in Dyness or are big brand names alone accounting for the price difference?

What big band names? They are all Chinese, I've never seen any one say to avoid one brand or another. 9 times out of 10 the best quote is the cheapest quote.

kavanaa1

Would appreciate any steer if this is good , bad or middling.

Also any suggestions for inverter, battery location - no space in utility and attic difficult to access.

https://www.boards.ie/discussion/comment/123319680#Comment_123319680

@helimachoptor's quote on 3rd March post at €7.5k is only 6 panels shy of yours, albeit different inverter and battery. I can't see 6 extra panels adding a €3000 difference, and the SAJ inverter quoted at 6kw should have the head room to take the extra. You need to know if your inverter clips at 5kw, can divert most of the extra over the grid limit to the batteries if uncharged. Only an issue on full 8.8kw output. I'll leave it to others to compare Solis to SAJ inverter and Wako to SAJ battery. Would be nice to know where he got that quote, but we're not allowed ask. Meantime, you can check out SAJ gear from this materials supplier Solarboss.

https://solarboss.ie/collections/premium-solar-panels-collection.

A 440W panel is €70, getting on for half what they were costing a few years ago.

Hi all, got my 1st quote today, (no site visit)

20 x Jinko Panels

Solax X A3 Hybrid Invertor

SolaX T-BAT-SYS-HV-5.8

5.22 kWh of Usable Capacity 10 year warranty on battery, no mention of warranty on anything else. No mention of Ber or paperwork either.

10k total cost looking for payment of 8.2k so i' presuming they claim grant back instead of me? Any advice / opinions welcome

Can you tell me where you got quote 3 from. I'd be looking for something similar

Gulliver

Hi all

I got the quote below and had a look at the David Hunt calculator and it says this is at the upper end. Not too sure about Solax as I have read that I can't add any battery other than Solax brand to it later (e.g. can't add the Seplos 15 kWh kit).

Any thoughts?

13 x Luxor 435w panels

Solax X1 Hybrid 5.0 inverter

After grant cost €6995

Optional:

Eddi: €595

6 kWh Solax Battery €2600

Changeover Switch €795

Can you tell me the companies who quoted you this price and where you are located. I'm getting prices of 11K for option 1 but with a 8Kw battery.
