Still better than I was doing and if you think installer is most likely getting it better than 6.5k then that's 6k-ish for a day's work.
Maybe things might actually be better value when the grant goes!

So even after paying roofer & spark & profit cut, 12k (pre-grant )seems a bit on the high side to me but I think we're in the worst situation now.
Everyone rushing to install PV before grant goes out, installers are busy AF can turn down jobs if you don't like their high quotes
Can't see a lot of 12k installs once the grants are out.

I also have a brick flat roof shed that I wonder could take panels. But it’s about 20 feet away from the house so would need cables running.

Could be a great option. No reason why it cannot take them. You could put the inverter in the shed and just run an armoured electric cable to your board.

I have run DC cables from my house roof out the my inverters located in the shed, so there's no issue running AC or DC cables a decent distance

That's mad money if it's before the grant and probably still high if it's after it.
Why do you want 2 batteries with FIT coming in.? You would do better if you got rid of the diverter and put up more panels with the saving.
Sending you a pm.

That was the initial quote before even a survey/phone call, just on the email I sent.

It's before the grant.

I currently can only heat water from the oil boiler and have to fire that up just to get some hot water. Also have constant queue for showers (parents training each night and 2 active kids). Is it still advisable to shy away from the diverter?

rx8 · 07-04-2021 1:26pm

That seems like a lot of hot water there. The diverter will only start working when there is excess energy generated. So the 1st thing to charge will be batteries and then the diverter will kick in. Maybe don't bother with the batteries at all, the difference in the grant is only small. Your excess will then all go into the water heating and to the FIT, once it comes in.

When you use the oil to heat hot water, can you only heat the tank?

You'll not save money with a diverter, but there could be a convenience factor. Also depends on how deep/position of the immersion is, how much of the tank it will heat.

If you go into this knowing that it's hard for the diverter to pay for itself, and your getting it for convenience, it's up to you to judge if it's worth it.

Eg my parents. Have a hot water diverter, got it for the summer, so they don't have to keep a fire ticking over for them to have hot water.

Theoretically we should be able to heat just the water tank, in reality, it heats the rads on the way to the tank too.
2 bedrooms, bathroom, and walk-in

That then could skew things a bit in your favour, in summer.

I'd look into getting a smart heating control with smart TRVs too

slave1 · 07-04-2021 2:19pm

Family of 4 here, myself, wife and two teenage daughters with long hair so high hot water demand with minimum 5 showers a day.
So far in April I've let a lot of PV go to the water i.e. 78kWh and as it's all done automatically, there's no flapping around with switches etc.
Also it is better to consume your PV before letting it go to battery/grid etc.

Hot Water Diverter is probably financially flat over it's lifetime (as depends on install cost and how long it lasts) but it is very convenient and a lot better that burning fossil fuel.

All week we've had plenty of hot water, all from the sun

A quick FYI on this point. The SEAI now has an online application where the homeowner just has to submit MPRN, house location and select their solar installer from the drop-down list of SEAI approved installers. The confirmation comes straight away and then you have 8 months to get the installation completed and BER cert.

So best to get that done as soon as you've picked your installer.

The site to register your solar grant claim is here: https://mgen.seai.ie/

slave1 · 07-04-2021 5:08pm

I actually thought it was 6 months, 8 months much nicer.

Solar installers are busy because this is the season for it, lead time much less Oct-Feb

DrPhilG · 07-04-2021 6:05pm

I confirmed my order in early July. Installer had me live before the end of the month.

Not bad but the inverter is too small, reprice with a 6kw Solis invertor. The price difference is very small.Better to be looking at it than looking for it.

Not bad, you have a Harvi included, see is it possible to run some Ethernet cable instead, hard wired will always be preferable and is also permanent.
The cables need to run from PV and Grid feeds back to wherever your are putting your EDDI hot water diverter.

Thanks for that, I'll mention that to the installer. I have ethernet pulled into most rooms and empty ducting so no hassle in using them over wireless

It's not actually ethernet(tcp/up) that's run over the cables, the cables are just used for simple signals, from the Cat's so an ethernet over power isn't suitable.

An Eddi does NOT need to see the PV generation. It only looks at the grid and ensures that the grid figure stays at Zero.

So if the Harvi was for sending the PV generation, then that's pointless. Only the Zappi needs to read the PV generation

Why does the zappi need to see the PV generation any more than the eddi? Mine seems to work fine without being able to see it.

Interesting that - and what you say makes sense really. I don't know - I always thought that PV output was needed to be known for Zappi's, but clearly not.

Because to operate in Eco or Eco+ mode it needs to differenciate PV generated power.
If it is not CT'ing the PV generation then how else will the Zappi know to either supplement with Grid power or even if Eco+ (100% PV power only) possible?

Don't know why we are debating the inclusion of one extra CT Clamp in an overall outlay typically €5k+.

Agreed on battery, it also makes sense to get an EDDI IMHO and you can run CT clamps to that if easier than the Zappi2 to get full functionality out of the MyEnegri gear you have.

Both quotes are too high, I know it's a pain but I highly suggest you read both the 2018 and 2020 (this thread) Quotes in full to see this yourself.
As an example, I put in a 7.4kWp panel system with 5kW hybrid inverter and 2.4kW PylonTech battery, all the safety gear etc etc for €5.6k after grant.
DrPhil and others got good pricing too.
You'll have to PM for recommendations as public naming of installers currently against forum charter.
Shop around, put as many panels up as possible (ignore planning restrictions) and get as big an inverter as possible, there is little difference in inverter prices the higher you go...

Thanks for the feedback! Yes the Eddi is included in both quotes as thats what I requested, along with a Harvi.

I think the first quote is using solartricity as their supplier as when I run the same config through it comes back similar with same part numbers etc., less cost but the are running a business so I would expect some markup.

However quote 2 looks VERY expensive and looks like the inverter is not as good as the one in quote 1, certainly a lot cheaper yet their price is much more. Very disappointed here with their obvious price gouging. I looked back over the thread, but the prices are certainly different to the ones we are getting these days.

I just want an honest quote at an honest price, seems to be too much to ask for now which is really frustrating!

SD_DRACULA · 08-04-2021 5:18pm

Having priced all the parts myself, seems like a lot of the companies are asking for 4k to install/profit just because they're busy and because they can.

4k easily...I'd say some are trying their luck at 6k plus if we assume they are getting the material at significantly less than we could.
Ultimately if you want to go green/lean towards off grid (at the moment) then don't expect to break even, ever I think. The products will need replacing before they are paid off at today's quotes.

I wasn't debating having one, I was querying why championcc thought the zappi required a ct on pv generation for it to work properly but the eddi didnt (neither of them do).

The zappi doesn't need a ct on pv generation to utilise Eco or eco+ mode correctly at all, it just needs one on the grid feed so it can detect when you are exporting. The one on pv generation is just a nice to have for logging purposes.

slave1 · 08-04-2021 6:29pm

I never realised that, still, for such a series of costs I would insist on a second CT to gain the functionality and I assume future proofing for when MyEnergi can handle battery charge/discharge

Agreed but not all setups are the same, my setup is a bungalow. so no scaffolding and very straight forward one day installation.

Some are over multiple aspects, multiple roofs and at height.

Can't ever see them supporting a DC / Hybrid battery. My hope would be that they will be able to have an AC connected battery have a prioritization between a Zappi and Eddi. At present, it's either before both or after both.

I no longer use the MyEnergi app as I now use a Node Red Dashboard, being fed by a data stream from the inverters' RS485 port.

garo · 08-04-2021 8:49pm

Agreed. A second CT will not help the Zappi distinguish between solar PV and battery output. I agree with Mickeroo that the PV CT is completely unnecessary.

I think the zappi has the option of charging on solar not just solar excess (ignoring the house useage, that's just imported)

garo · 08-04-2021 10:45pm

Ah ok. But I really don't see the point of that. Electricity is fungible. Just set the min green setting accordingly.

It doesn't though. It operates perfectly fine with just a grid CT, it bases all it's decisions on the amount of electricity being exported to the grid (even if there's a CT on the PV).

In Eco mode it tells the car that it can draw either 1.3kW or the amount being exported to the grid, whichever is greater. It continually adjusts the amount going to the car to prevent export to the grid, but it never tells the car to draw less than 1.3kW, even if that 1.3kW is taken fully from the grid.

In Eco+ mode, it's the same except it won't send the minimum 1.3kW to the car, it will only send whatever would be exported. So, if you're only exporting <1.3kW, it'll stop the charging until export reaches that minimum level (although there are menu options to allow a lower percentage of green electricity to be used).

Don't know why we are debating the inclusion of one extra CT Clamp in an overall outlay typically €5k+.

True enough

It's also required for the App/online account to provide PV generation data

It's only required for the Zappi display/App/online account to provide accurate PV generation data.

It can make a good guess at PV generation in certain cases even without PV CT, e.g. if there's any export, it marks that as being PV generated, or if you're charging the car and sending 3kW to the car, but it detects 0 grid import, it marks the 3kW as being PV generation, since it knows it must be PV generated since it's not coming from the grid.

Northumberland · 09-04-2021 7:51am

How high can you actually go with a hybrid inverter? I see various mentions of Solis having a single phase 6kW hybrid inverter, but I can not find it on any of the major Irish or UK websites - midsummer etc, the largest is the 5kW - (which I have). On the Solis site, and others, I see a 6kW, but it is 3 phase and does not have the nice big screen showing all the power flows etc etc.

Caspero · 09-04-2021 9:47am

The Zappi manual from page 30 shows what the additional CTs are used for: https://myenergi.com/wp-content/uploads/2019/04/zappi-manual-v2.0_english.pdf

Not sure this will format well and the image is missing but here's a copy and paste:

CT Sensor Installation
Current Transformers (CTs) are used to measure current at various places of the installation. For example, the Grid connection
point, the solar/wind inverter or a static battery system.
Installation of a CT to monitor the Grid connection point is required. Other CTs are optional and can be purchased separately.
The number and location of CTs used within an installation will vary according to devices installed and the user requirements.
CTs can be wired to any myenergi device with CT inputs (e.g. eddi, zappi or harvi). This enables very flexible installation as the
CT can be wired to the nearest device. Note: The harvi device can be used if it is not practical to connect any CT to the eddi or
zappi.
Once installed the CTs need to be configured, see CT Config (p22) for details of how to configure the CTs.
Grid CT
The Grid CT sensor (supplied) needs to be clipped around either the Live or Neutral meter tail of the electricity supply meter. If
using the Neutral conductor, reverse the direction of the sensor (so the arrow is reversed).
The positioning of the Grid CT sensor is crucial, take note of the following when deciding where best to install the sensor:
✔ Can be connected to any myenergi device with a
CT input e.g. the eddi or zappi (wired sensor) or
harvi (wireless sensor).
✔ ALL of the import and exported power must be
'seen' by the sensor – be sure to install it
upstream of ANY junction box or 'Henley Block'
(the CT can be fitted inside the consumer unit).
✔ There must be only one Grid CT per-phase for
the whole installation. (There can be other CTs
but only one at the grid connection point, also
note CTs for third-party devices do not matter).
✔ The CT should be on the Live or Neutral cable.
✔ The arrow on the bottom of the CT sensor must
be pointing towards the consumer unit (in the
direction of grid import) if on the Live cable, or
reversed if on the Neutral cable.
✔ Ensure the CT is fully closed and clicks shut.
✔ Be sure to wire the CT the correct way round;
black [–], red [+] otherwise import and export
readings will be swapped.
Additional CTs
There is an option to add other CT sensors (available separately) for monitoring the generation or other appliances such as
battery systems or general loads. Installing a CT for the generator (PV system) will allow the main screen to show the generated
power and the total power consumption of the all the other appliances in the property.
CTs can also be used to limit the power drawn form the supply. See Load Balancing / Current Limiting p32.
✔ Additional CTs Can be connected to any myenergi device with a CT input that is linked to the network (see Linking Devices
p24).
✔ The arrow on the bottom of the sensor must be pointing in the direction of normal power flow (e.g. away from the PV
inverter) if on the Live cable or reversed if on the Neutral cable.
✔ Ensure the sensor is fully closed and clicks shut.
✔ Be sure to wire the CT the correct way round; black [–], red [+].

Extending the sensor cable
If there is a need to extend the sensor cable, twisted-pair cable like CAT5 or telephone cable must be used. DO NOT use mains
cable, bell wire or speaker cable. It is important to use only twisted-pair cable to maintain signal integrity. The cable can be
extended up to 100m.
Wireless CT Sensor (optional accessory)
In some cases it can be difficult or impractical to install a wired sensor. For example it may be
the case that the zappi unit needs to be connected to a sub-board, rather than main
consumer unit and two consumer units are in different buildings.
The solution to is to install harvi – a clever little device that enables the zappi and eddi
products to be installed without using wired CT sensors for measuring the grid and or
generation power; instead the CT sensor is connected to harvi.
The harvi does not need batteries or a power supply – the energy from the sensor is
harvested and used to transmit the measurement signal to the zappi or eddi. This means
batteries or electrical wiring are eliminated!
Up to 3 CT sensors may be used with harvi and it also supports 3-phase systems if three sensors are connected.
Refer to the harvi installation guide for details on installing and configuring harvi for your system.
CT Golden Rules
Grid CT
• Only ONE Grid CT per phase (check for only one ~ symbol in Linked Devices Info).
• Located to ‘see’ ALL import and ALL export current (i.e. always upstream of any junction box).
• Arrow pointing in direction of import (e.g. towards consumer unit if on Live cable).
• Must be on the same phase as the Master myenergi device.
All other CTs
• Arrow should point towards the consumer unit.
3-Phase harvi CTs
• When using harvi in 3-phase mode, the CT inputs correspond to the phase number (e.g. CT1 = Phase 1).
CT can dos
✔ Can be wired to ANY myenergi device in the network.
✔ harvi can be used to make ANY CT wireless.
✔ Cable can be extended up to 100m (must use twisted-pair cable e.g. one pair of CAT5).
✔ Cable can be shortened.
✔ Can be clipped around two or more conductors feeding appliances of the same type (e.g. two Live cables from two
inverters that are on the same phase).
✔ Can be in close proximity to other CTs.
✔ Wires can be swapped around in device to reverse the direction of the readings (e.g. change import to export).
✔ Can be grouped with other CTs of the same type so that the power reading is summed (e.g. east and west solar
Generation).
✔ Can be used on the Neutral conductor (direction of arrow or wires must be reversed).
✔ Can be set to None if you want to exclude the reading.

Hi all,

I'm undertaking a house restoration project this year and would really appreciate some help on this subject! 3-phase supply to the house and looking to have a substantial PV array (22-28 panels) as there's an ideal south facing unobstructed roof which would work well. I'm looking for a company just to do the roof work as I am an electrician and can do the wiring. If anyone can PM me a company name that might be worth getting a price, it would be much appreciated!

Thanks for the feedback! Yes the Eddi is included in both quotes as thats what I requested, along with a Harvi.

I think the first quote is using solartricity as their supplier as when I run the same config through it comes back similar with same part numbers etc., less cost but they are running a business so I would expect some markup.

However quote 2 looks VERY expensive and looks like the inverter is not as good as the one in quote 1, certainly a lot cheaper yet their price is much more. Very disappointed here with their obvious price gouging. I looked back over the thread, but the prices are certainly different to the ones we are getting these days.

I just want an honest quote at an honest price, seems to be too much to ask for now which is really frustrating!

UPDATE

I have now finally a quotation from a well-documented and used company here on the boards...

Here are their quotes BEFORE the grant, remember they handle the grant application so take the grant directly & require a 25% deposit which I think is fair. The grant for the 10 panel with a battery option has a possible value of €3000 according to the grant application:

10 PANELS 340 WATT JA SOLAR 25 YEARS GUARANTEE.

2.4 PYLON TEC BATTERY
3.6 SOLIS INVERTER.
EDDIE WATER DIVERTER
WIFI DONGLE.

PRICE 7900 EUROS INC.VAT.

MINUS BATTERY 6900 EUROS INC VAT.

**********************************

8 PANELS 340 WATT JA SOLAR
2.4 PYLON TEC BATTERY
3.6 SOLIS INVERTER.
EDDIE WATER DIVERTER
WIFI DONGLE

PRICE 7400 EUROS INC, VAT.

MINUS BATTERY 6400 EUROS INC.VAT.

PM me for details if you want the companies details.

:cool:

Can someone cast an eye over this for me, as I'm honestly going quote blind
Before grant but would be at a lower rate, yeah?
