Yeah, WiFi dongle is in the scope of work.
So what I'm hearing is that MyEnergi will show everything with hub (my zappi isnt the new one) and an extra CT on the solar output just in front of the consumer unit.
BUT myenergi doesn't distinguish between solar and battery, it just sees the inverter basically and everything beyond is a black box? Sort of makes sense given how CTs work, but seems a shame the inverter can't talk to the hub.
So then need the solis app to monitor the battery/solar array setup.
I've been hoping that with the new zappi out, myenergi will start flogging the hub but alas not yet!
Get an inverter monitoring wifi dongle. Essential imo. Every installer should be able to supply one. They might even chuck it in for free if they are decent.
Short answer is no , not all on one app. Depending on what version of a Zappi you have you will need a Hub and another CT. The Myenergi app will show the Solar Generation After Battery if you have a CT clamp on the Solar output before your consumer unit (Set to Generation) , your CT clamp on the grid (Set to Grid) shows the import / export to grid which allows the Zappi to modify what its takes. The Myenergi app will also allow you to adjust how much excess you have before your Zappi starts charging ..100% , 90% etc . The Solis app is quite good ..you need the Wifi Stick for it tho. The Solis app shows the Battery charge / discharge and status .. the Myenergi app won't as you can't clamp on a DC feed.. only an AC battery.
I was looking for these as well a while back, 8mm size if I recall but they were too expensive and do it right you also need a special crimper, also crazy money for that.
Went with pylon cable kit and snipped one of the ends.
Thanks connesha, an option at least. Have cables with the battery so need to change one of the connectors only.
I had originally tried sourcing these too, but gave up and got the pylontech cables made-up instead from this guy.
If they suit you, ignore the "out of stock" notice on the website. Just phone him, he most likely has them... the website is always out of date.
Does anyone know what size the Amphenol Surlock connector in on the Solis inverter?
Is the clip into the invertor a standard size and then it is based on wire gauge into the clip?
Is there anywhere locally that would stock these, electrical wholesaler e.g.
I got solis to adjust my import bias down to 50W. That seems to have sorted the problem. I'm only seeing a small amount of export overnight where it was draining the battery before morning.
With the adjustment between 7pm & 7am it was 0.5kWh export and 0.9kWh import. I'm talking about tiny numbers so I think I'll just leave it alone now. Perfect is the enemy of good or something like that...
Have install lined up for January, and just taking the time in between to make sure I have exactly what I want configured in the install...and have a question re interface/apps etc.
So am getting 4.5kW on E/W, with Dyness battery and Solis Hybrid Inverter. Not getting an eddi.
Currently have Zappi charger, with Harvi tucked away in my meter cabinet.
Will I be able to see all the things I need in one interface (preferably an App)? Things I need/want being solar generation/battery status/household load/grid import/export/Car charging or not etc? I'm assuming Ill be clicking through inverter menus to change more hardcore requirements but for day to day monitoring (and even CSV downloads?), I'm curious what I can get by default, and then if any upgrades (e.g. MyEnergi Hub?) would make for a better experience?
If you are going to increase the number of panels in the future then that time is now, getting roofers back and putting up (likely) different looking panels with different voltage is something that will turn out to be a total headache both financially and potentially visually.
I'd be looking for at least a 5kw inverter even with your current panels..
Unless there's some reason to be restricting down to 3.6
Hi,
Thanks so much for all the advise and wisdom. New to all this and very grateful for yer tips. Have panels fitted and waiting on electrics to be hooked up.
This is my package. 5.32kW (14 x 380W Solar PV panels), 3.6K Solis Hybrid Inverter, 2 x 2.4K Battery Storage, eddi Power (Hot Water) Diverter.
Should I ask for a bigger inverter if I increase panels/battery in the future.
Thanks again
I'm wondering if disabling charging from grid will sort my problems out. It seems logical but solis seems anything but...
On the voltage issues, I'm up the road in Balbriggan which is fed from Loughshinny & Glasmore. Highest I've seen is 245. No issues so far.
General import settings, only place I've seen them is under the inverter advanced settings
Now that's a bit cheeky! seems the 100W import bias was a bit too much but it gives a good place to start. I'll get my smart meter import data after the weekend and see what the offset would need to be. I'm thinking more like 15-20W but will see.
You can see the import below. It ended up that the battery was only covering the peaks. Base load is like a square wave due to the fridge-freezer.
Do you mean the offset? I don't think there's any front end for it and it's only on one specific version so far, not general release.
Are all those Solid settings only available on the inverter or can they be got at via the app/ Portal?
👍️ To be fair, the local ESBN guy did phone me directly later in the day to see if all was Ok then. They had gotten a few reports from other people too that morning (Andy?), but unfortunately they didn't know what it was at that time. It lasted 3 hours in total. For the first 2 hours it was over 260V, and the last hour was over 253V.
I guess the problem is that the supply standards is 230v +/- 10%, but if your inverter is upping the voltage beyond that.....while it might not break the inverter, you potentially could be altering the supply spec for your next door neighbour. The local sub station should be able to handle the backflow without tripping, but I guess it's hard to say that everything on your street can.
I don't know enough about the technical merits of it to be fair, but my suspicions that if your inverter is outputting more than 254v, then bad-mojo could happen.
An offset adjustment would be great. I requested similar previously on the Solis portal but rather than just not respond, they went one better, and deleted my ticket. 🤷♂️
For everyone else's benefit, 269V and 281V(!!) is referenced in this ESBN document;
Conditions Governing the Connection and Operation of Micro-Generation (Section 2.2 Interface Protection Settings)
Solis have translated these settings into Solis parameter names here:
I'm not sure if anything else is configurable unfortunately.
Supply spec is 230±10%, but as per above the ESBN requirements for inverters are approx 230±17%. I presume this is to avoid solar PV inverters exacerbating issues around the fringes of supply spec.
Next time it happens follow the yellow ESBN vans up to Loughshinny 38kV station and see if any of them will let you in on what the cause is. 😉 Probably a ground fault on one of the other phases. If it is any help, my local 38kV station is also fed from Glasmore and I saw no issues this morning.
I believe this is something that they can set only. It's not a standard firmware but one made for a specific issue. I opened a ticket by email/portal but follow up by phone. It was a few weeks since my last reply though. It took about 40 mins to get through so you need to be patient. I think there's just one manning the phones for end users at a time.
The service desk is https://solis-service.solisinverters.com/support/home
Yea, being able to set a margin would be very useful. Can you control the amount of.bias yourself? Or they set it?
And how are your contacting Solis? My request has gone unanswered for over a week now...
I was onto Solis earlier again about my import and export issues overnight. They've now put me back to A10032 firmware. The guy I spoke with actually wrote that one and said it has a few features and tweaks that the main one doesn't. He said he's trying to get HQ to adopt some of them into the general release. One of the features is an offset adjustment. They can set it on an import or export bias to balance it. In my case it was exporting a lot so he put an adjustment in place. I'll see how that goes and may get them to change it slightly.
Interesting thing I noticed this morning during the 'over voltage'.. When I went to spark the gas hob, I noticed that the spark rate was much much faster than normal, and since the voltage returned to normal, the spark is back to its usual rate!!
I can't comment on where 269V came from. Jonathan is usually very clued in, but it's out of spec for ESB. It's been 230v +/- 10% for decades.
Voltage Issues (esbnetworks.ie)
I understand that the inverter will go there to 269V, and it will solve your alarm issue and get your system working......but it's very much outside normal operations. I don't say this to give out or anything, actually only to potentially save you some grief if you blow a telly or something. I'd be Jonny-on-the-spot with getting onto ESB about that.
(To be fair it's unlikely that you'd cause damage, but if your pushing voltages in the high 260's things aren't expecting that....and you could run afoul)
Well if it doesnt work I simply wont be paying the remainder (12k owing) until it does. They havent actually delivered me a working system yet.
Thanks, yea, exactly. The 269V is the Alarm voltage, set in the IE settings in Solis. What I'm trying to see if anyone knows, is if there is any other setting that can be set...
I don't think an installer is going to do anything for this issue. I'd expect their line to be that they set the IE regs setting. If anything goes outside that then that's your/ESB problem (but not them)
Yea, that's understood. There was a post a while back, by @Jonathan IIRC, pointing to an ESBN doc that said the grid could go to 269V. Hence the 269V value to Alarm at
I'm contacting the ESB separately (That is a different angle; this post is a query about inverter settings.)
I'd suggest that there's another setting downstream in the inverter you need to change in conjunction. What you've done there is allow higher voltage in, but I don't see anywhere that you've changed the output voltage configuration. My inverter (before we had to turn it off) was preset to the IE regs so I guess the output voltage is preset and to operate at a different incoming voltage you'd need to also change some settings in the regulations settings.
I've decided simply to not play with it yet - although it's tempting - as I've already got the installer coming back on wednesday and that's what I'm paying him to do
