My installer provided a Harvi free of charge as it was easier/quicker than trying to pull the CT cable. You might be able to return the items you bought if they aren't used.
Our installers just turned up on the day and after a brief chart about what was involved they went about there business, wouldn't have known they were there other than a load of panels on the roof and having to pick up a few cable ties afterwards.
I understand where you're coming from!
In less than three weeks I too have the installers in to fit a solar PV system. The lack of communication is worrying me too.
I've thought the system through with the help from people on here and already purchased a Harvi and an extra CT clamp as there is no easy route through from the Hot Press where the immersion and Eddi will be, and the Consumer Unit. Even if the installer knows of a way, it has to be easier for him to use a Harvi to send the signal....and the extra CT clamp will add the import figure onto the Eddi display.
I've never known installers of anything to tidy up after themselves! When I finished this house (I bought it at first fix) the electrician, plumber, plasterers and carpet fitters all left a mess behind. The plumber pulled up my block paving outside to run an oil pipe and didn't re-lay it. I was 4 years on the sites in the UK and I left anywhere I went at least as tidy as I found it, seems things have changed.
Sorry I couldn't be more help, but you are not alone in your panic, for what its worth.
Hi, My installer is coming next month to install panels. I am just wondering how this typically works.
Do they send someone out to inspect, and plan the install with me beforehand, or do they just turn up on the day and start installing?
Do the installers typically toidy up after themselvses e.g if they need to drill holes in walls do they re-plaster around the area or do I have to do that?
I have a small wind turbine that I can install and it crosses my mind that I should hook it up to the inverter also. Is this possible?
I am beginning to panic a little as the date approaches. Anything I should be doing to plan for this?
Yes, PM me
By any chance does anyone have a spare zappi CT clamp? The price for postage of them from myenergi is just wrecking my head.
Slight correction - the solar / grid / battery will be used when solar drops below 1.4kW, to bring charging up to 1.4kW
But when solar excess exceeds 1.4kW, only solar is used.
So ECO can drain your battery if you don't have some automation controlling it (or keep an eye on it)
If zappi is set to eco it will draw from solar/grid ( it doesn't care where it gets energy from) @ 1.4kw, however if for example the batteries are full and your Pv is producing 4kw , well then your zappi will take that full amount and put into car.
Just got a zappi. Have been using granny cable last few weeks which has been great as it only uses 2.2 kW meant during middle of day I could be charging car and still charging battery (just much slower!). Is there a setting on Zappi i can do something similar? ie set it to charge the car at minimum of 1.4kW while the house batteries are still also charging but if batteries hit 100% the zappi will then use the 1.4 or higher?
Good to know. Thanks for sharing.
No plans at the moment to install a Zappi as I don't have an EV and it will be several years before we do.
I think the best option is a Harvi.
Thanks!
Have you any plans to install a Zappi ? Cat's can be connected to a Zappi and the Zappi and Eddi share the info internally over their radio / hub network
Eddi needs a CT, doesn't have to be a Harvi if the installer can run cable to the consumer unit (which they'll be doing from your inverter anyway).
My meter is far from the consumer unit, that would have been fine but my consumer unit is technically a secondary unit as I have the car charger installed between it and the meter. Installer had to run cables to the far side of the car unit rather than the normal consumer unit as planned.
1. My solis is in a lean too I built recently. The internal temp was 59.2 degrees then other day, at the moment its 50.3. They can get up to 75
"void over heating ambient air temperature must be considered when choosing the inverter installation location. Ginlong recommends using a sun shade minimizing direct sunlight when the ambient air temperature around the unit exceeds 104°F/40°C."
I hope its okay to post a series of questions here. As I've got a deposit down on a fit happening in three weeks time, there are a few little things I'm just wanting to confirm and as I've clearly bored the pants off the installer, I thought I'd ask here.
1 - I have a Solis Inverter being installed. The installer said it's likely to be mounted in the loft. My loft gets incredibly hot; in excess of 37 degrees one day last week. I know the Solis has a maximum of 60 degrees ambient temperature but how hot do these things get? I ask as if the product itself adds to the current ambient heat, we could be getting close to maximum. Or am I overthinking this?
2 - I'm having an Eddi fitted. Can the Eddi work without a CT clamp? I ask as the immersion is dual element and to use the two outputs from the Eddi, the device needs to be mounted in the Hot Press which is away from the Consumer Unit. If the answer is 'no', can I safely assume I will need a Harvi?
3 - Is access needed to the (outside) meter cupboard for any connections? Mine is inaccessible from inside the house and the Consumer Unit is remote to the meter box. Again, I ask as any connections needed will have to be surface run, not something I am enormously happy about!
Thanks in advance for any answers, or remove if not allowed for any reason (new to this forum)
I got €200 credit with SSE, plus €675 credit from VW.
Still nearly €700 in credit currently.
When I looked at the Solis app a few times recently it appears my battery is discharging when it gets to 100%, despite there being plenty of excess to power the house etc.
E.g.,
-4Kw of power from solar
-200W coming from the battery. Battery is at 100%.
3. 2kW to house
1kW to grid.
So, it looks like theres power coming from the battery when not needed? Anyone seen this? Is my battery overcharging?
I'm sure I've seen this question asked before here, but the search is brutal since they changed the site.
I got €210 credit when I signed up with EI last July. This has been the cheapest year for electricity.
And when I signed up with EI in Jan on their EV plan, I got a €300 credit. So added to the €200, I have only used about €180 in total since Jan. I could easily see myself getting all the way to October on credits !!!
Ah don't kill my buzz 😃. I don't mind i still have €121 credit left from the government money
I'd say a lot more than that in reality, the solis import value is way off
Seems to always use a tiny bit when the cooker/oven are on (even though usage is under 5kwh) quite annoying actually.
Solis reports 0kwh import for most days this month but that is fake news in reality 😥
This is what we have become 🤣🤣🤣
I'm at 1.3kwh imported this month and that pissed me off
That extra 100w draw from battery is mixture of AC/DC losses and the fact the inverter is DC powered using slight power
I have noticed my Solis inverter draws from the grid for a minute or so just as the batteries hit 99-100%, today the inverter showed 800 watts being imported even though the batteries were full and there was 3.5kw being generated, I checked my old meter which goes both directions and it was going forwards for that time. Luckily where my system is I can check it as it's only in the lobby beside me where the meter is. I also noticed a few other discrepancies like the base load is 150 watts but battery shows draw of nearly 100+ watts more on the inverter screen.
I also can see the fluctuations when you turn medium or heavy loads on, it's as if everything is trying to figure out what's happening and draw and push power until figured out to each other from a few seconds to maybe 20+ seconds and then settle down.
Moved from the quotes thread, since its not about quotes. 😉
Since things have gone quiet I'll ask a question. Does anyone ever see an occasional rogue kWh be imported from the grid. Every day I export 5 to 15kwh and an odd day I'll see imported 1kwh which bugs me. I have a battery and I thought it might be when I use my oven but tried it today and seems not to be the case. Happened during daylight hours so and there's no real over loading of the system. Curious to see if anyone sees similar :)
Yeah, nothing off the shelf as it needs to have something that can monitor the grid.
Last year I got some energj smart plugs and flashed tasmota onto them. The ones I have can also monitor the power used by the plug. That's something to take into account when designing the system.

No need for any JTAG headers. Two possible solutions;
1) Get the Eddi relay board. Use the relays as your smart switch.
2) Use something like HA or Node Red to monitor the grid import/export and toggle a smart switch accordingly.
Does anyone know if there's such a thing as a smart diverter socket? As in a socket that only activates when you're exporting above a certain threshold?
Basically an Eddi but that you can plug anything into
I'm sure I could make some solution from a smart plug and some home automation, but I'm too lazy to dig out the JTAG debugger and figure it out 😁
