The actual "builder" was very positive about filling the roof with panels. The architect is pushing her builder and therefore her M+E crowd. Strange that they wouldn't be more interested (especially when the scaffold is in place!!).
Ah here, this firmware is even worse. Went out for dinner with the Mrs this evening so nobody home. Bare essentials on.
Flat line on import is where there's still a bit of generation, once that stops then it's party time. Going wild importing & exporting! See screenshots. This a mixture of the Solis data and myenergi data.
It's also back to dumping 300W constant out of the battery once it charges. Where do I even go from here?!
Worth asking to be reverted to the fw version I'm on? No issues here.
If issue persists on 3A0029, then might be an issue with your meter or CT?
Not the right home for this maybe but I thought this was interesting and worrying. We're in dire straights climate wise and the lack of info and understanding on the benefits of solar is scary. From the Unearthed mailing list.
"Meanwhile, in England, both Tory leadership contenders have a bizarre answer to the food question. In their pitch to the two hundred thousand people tasked with choosing the next prime minister, they have spoken out against the ‘threat’ of solar panels using up farmland in the middle of a food crisis. A neat Carbon Brief factcheck shows that solar panels only take up 0.1% of land in the UK, even less than golf courses."
I will ask them to roll back the firmware to that one or at least the previous one I was on. The guy seemed a bit dismissive. Comparing to my readings from earlier in the year prior to the install my usage is much the same overnight... and I have a hybrid inverter so it shouldn't be. It's effectively not providing battery power for the house demand aside from big loads, but dumping it out and importing.
I was thinking this evening if it's perhaps an issue with the Acrel meter. If it's giving the wrong info to the Solis then that may be sending it haywire.
The first thing that I would do is look at the CT clamp and it's connection back to the inverter. How far is this cable run ? Focus on joints in this cable, possibly badly made
After that, I think I'd also go with Jonathan's version - a known good working one. You can then compare apples with apples
Cable run is from attic down the back of the house, across kitchen, and into utility in the centre of the house to the consumer unit. It's a bit of an awkward run. There was a cable in place from the prior install which is internal but they just used that for the backup. I'm thinking maybe get Solis to roll back firmware and then get onto the installer. It was done in June.
Could you run a washing line cable to prove the point ? Or re-terminate it yourself ?
Can anyone recommend a plug and play energy monitor? Ideally like to monitor 3 seperate input/output (House,Shed,Solar PV) but at least 2 (House, PV) at minimum.
I'm no electrician so getting messed up with the Fuse board probably wouldn't work well for me but throwing a CT clamp around a wire should be doable.
Any products people would suggest?
Not sure if this is the right thread but, I’m waiting on a few quotes for soar. I already have panels that just give me hot water and I can’t fault them. Get good hot water 9 months of the year. I also have 3 phase power in the house. Would any of this affect what I would need for solar ?
There a solar automation thread, so better to ask in there.
But there are numerous gadgets that could monitor power, temperature and other things, and feed it all into a raspberry pi
I'm not really comfortable messing with the cables on it.
Hi Jonathan. Here are the pics. From the below do you think I have 1 string or 2 strings?
Reminder that the issue whereby it only generates at 1/4 what it used to is only since the fuse replacement in Feb this year.
Quite possible the electrician that replaced fuse enabled Limit by EPM. No I didn't get any explanation of what he was doing at the time.
Do you think I should turn off Limit by EPM?
It's only 1x string. That's the postive and the negative two wires going into the inverter on the far left. By the looks of it, you have the space for a 2nd string (the two unusued sockets next to it)
Yep, limit by emp is the export limiter
Can't remember what the setting is. But it's in the advanced settings.
So as the lads above said, you only have a single string. This means that the string 2 voltage that you could see in your previous screenshot was just random noise, and not a malfunctioning string.
Turn off the Export Power Limit and you should be good to go. I would follow up with the installer though to figure out why they enabled it. See page 46 of attached for details of how to disable.
What's the best way to speed up a ticket in the Solis Service Centre? I've an unassigned ticket now a week.
Opened it via the website.
maybe send them an email: euservice@solisinverters.com
Hi All,
Anyone have a figure on ROI for adding more panels? i.e. large battery in place already, inverter has the capacity, is there a 1w of panel will save you x in electricity over the year type sum?
I'm sure DrPhil has done the Maths already :D
Thanks,
Gary
Plug your existing details into
https://re.jrc.ec.europa.eu/pvg_tools/en/#PVP%20that's%20the%20calculator%20for%20Europe
and then plug in your "expanded" arrary into the system and subtract one from the other. Bear in mind if you are currently exporting some with your existing system, it's not a given that all your extra energy being generated will be available, you may jsut export more.
Before that would have been problematic, but now with a FIT of €0.13-14 or sometimes €0.18-0.19 (Energia etc) it's not as bad as it was previously.
The self use percentage of each additional panel drops for each added. A big battery is great, but you also need to have the requirement for that power.
I now have 20kWh of batteries. Do it need that much - not a chance. But at €1200 delivered to my door, with the vat knocked off at the AliExpress checkout, I grabbed it before they copped on.
I've only the 10 myself with 3.3kw of panels. Adding another 2.4.
Always trying to reduce daytime load, not counting the EV we probably use about 12 to 14 per day.
Very true mate - although it occured to me after my post above that now with FIT....having a high "self-usage" percentage means less than it did 12 months ago. Technically every unit you produce now is "self-used" in some capacity, as even if your exporting to the grid...your getting paid for it.
Sounds like you have a Pylontech stack ???
You'd do well to go the 10kW DIY route and you could sell the Pylontechs and have money left over !!!
I had the 2kwh Pylon, selling that, have the LifePo up and running.
With the nightsaver "estimate" method I'm not really bothered about what I send to the grid, as little as possible hopefully.
Ah sorry, Adding another 2.4 was to the panels, not the battery !!! My bad
€1200 for 20kWh have the prices gone up a lot on AliExpress haven't seen anything like that recently
Brilliant, that worked Jonathan! Thanks so much.
Good idea for a business is a company that services/maintains PV installs done by another. I couldn't get anyone to touch my install with a barge pole as they hadn't installed it themselves. Total sh*tshow. I'm thinking of taking a course in this just so I know how to operate my own equipment.
I think he's referring to an upgrade. He already had 10kWh and added another 10 for €1200
