What battery config do you have and what does the battery voltage read after that event? Are all batteries seen by the Solis?

Hi all,

I've just replaced my Harvi and I'm unable to connect it to my Zappi.

It's a V1 Zappi and I've removed the old Harvi from the Connected Devices list.

I've cycled through the channels on both the Harvi and the Zappi to no avail.

I've also reset the radio comms on the Zappi. Still nothing.

Has anyone had this issue before? If so, is there a solution?

Thanks in advance.

Thanks jk,

I've emailed myenergi this week so I'll hopefully hear back from them soon.

If they are slow to get back to me I'll post on the forum above.

Thanks again!!

I assume you mean turn off the isolator switch for the Zappi. Leave it off for a half minute. Then turn it on again. Not disconnecting it from the fuseboard.

I powered it off before and had to restart it twice before if picked up our home wifi properly. Don't need to change anything on the Zappi after the restart. It holds it's setting from what I recall. Maybe check the charging mode is set as you expect. Like eco++

Got an email from my supplier (SSE) today informing me thatSmart meters will be required for FIT from 11th Sept and this change is applicable to all suppliers. Anyone else receive similar e-mails? DrPhilG are we likely to be able to get Day/Night rate compatible smart meters fitted in that time period or can we demand retention of our existing day night tarrif when we switch over to smart meters?

so SSE are saying that you won't get deemed CEG if you have a non-smart Day\Night MC002 meter from Sept on? I'd ask them on what legal basis they are basing that on. has the CRU mandated this?

and the installation of a smart meter by ESBN has zero bearing on your tariff, that is between you and your supplier.

FWIW I spoke to a lovely cheerful and most helpful girl in SSE who rather peevishly detailed the smart meter tarrifs and was even incredilious and a bit embarrased/amused herself when she told me the day, off peak and peak rates and all were higher than my current day/night rate. She said "I guess that's the price they expect people to pay for not reading their meters"

Anyway, I related what idc had posted and she said that there was a special code she had to input for these day/night rate compatible smart meters and she would specify that in their communication to ESBN, so that they don't come out and install a meter for me next week which isn't compatible and have to come back and install a new compatible one in Sept.

We'll see what happens next. She said I can expect some communication from ESBN

I have heard from a source in ESBN that a lot of the smart meters installed are being replaced already with different units due to corrosion particularly in coastal areas....where does it all end!

Maybe thats why the general cutoff - someones decided its winter and no one would be exporting anyway that time of year 🤣 irrespective of how many panels you have!

So, I have to apologise to everyone. I got solar installed this month and broke the weather we were having for all of June before that. 🙂

On a more technical note, however, I know that July has pretty much been a bust for Solar PV (at least in North Dublin). I got a 2.1 kWp system (5x420W panels, Growatt SH5000 inverter), south facing, and for the three weeks that it's been installed even with patches of sun, the highest peak PV generation we've seen is between 1.2-1.4 kW.

Is this something I should be worried about, or is it the bad / cloudy / wet weather is preventing it from getting closer to expected levels?

Should I wait and see what August brings weather wise before following it up with the installer?

Thanks in advance for advice.

Definitely something wrong there. I have two inverters one 1kW with 1.33kWp (SE) and 5kW with 4.65kWp (SE/SW) split and today north dublin 12.55 had a peak of 1.12kW and 4.7kW. So with a south facing array you should definitely be seeing higher. Also going back the last 3-4 days have all had similar peaks even with the current bad weather

The growatt reporting system is poor and exporting data is not very handy (I sense Home Assistant / Grott in my future) - sorry for the graph screenshots

Thanks @10-10-20 and @idc - I had a max peak today of 1.16kW (two times) and generally fluctuating around 800W-1kW from 11:00-14:30

• I'm not sure of the pitch of the roof, it's a standard mid-terrace (c. 2003 build) - eyeballing it, I reckon between 35 to 40-odd degrees.
• The panels are around the top of a dormer window, so there is some expected shading on one panel on either side of the window in the early morning and the late evening.
• The best day was on 8 July (mostly sunny with patchy clouds) - between 9am and 11am it averaged about 1kW+

8 July - best overall day with 7+kW generated

16 July - best day for 12:00-13:00 generation (average above 1.0kW)

Since going live on 8 July, it's produced 78kW - I know that July has been grim, but I feel it's particularly low.

Thanks again for advice.

@Fingleberries, 8th of July for me was 8.9kWh, and I have shading issues on my panels (hence the ratios for each colour differ over the course of the day)!

That's from Home Assistant. So yeah, I think you're seeing some under-performance. Can you be sure that you received 420w panels?

Oh, and I'm in South Dublin.

I got nothing from EI either.
