The crappy Solis Cloud is only a snapshot in time every 5 minutes. Look at the inverter screen or MyEnergi for Live figures
Updates to the MyEnergi and SolisCloud apps this morning and I'm not sure if there's an issue with one or other of them.
Wife has the washing machine on and SolisCloud showing a heavy enough load but MyEnergi has continued to show the home as being idle or much less than what SolisCloud is reporting. Even at that it takes a while to update the app to show usage across the home, Zappi and grid (was even showing grid drawdown at one point when there was none).
Activity then just drops off the app and it shows nothing happening at all across anything.
I recently put a poll on FB asking about issues left by installers regarding badly installed CT clamps. Shockingly, it was worse than one in 10 installs had CT clamp issues
Ffs, this just shows no dc testing was done. At least you're sorted now.
Finally up and running now. Reverse polarity in the cables. This obviously should have been picked up by the electrician bringing the cable from projoy to the inverter in the first place.
2 minute fix that took weeks. In fairness to the supplier, they gave me a discount on the final payment which I didn't ask for. It more than covers the lost generation while waiting.
The 9 panel string kicks in at 5am & the 4 at 7am. 8/5 or 7/6 split would be better but the lose is insignificant. Will keep an eye on it over the winter months though.
You might need to check that the supply cable out to the shed it suitable for the load from the panels. May have been just a basic one suitable for lights and a couple of sockets
The price of those batteries is scandalous. I've seen way cheaper posted recently. Keep shopping round and getting feedback
You will get more feedback in the solar quotes thread.
Maybe update post to include or exclude grant. 2100 can make or break a quote.
anyone got any feedback on this
Just received 2 x quotes
Option 1
18 x Jinko 435 Bifacal
Solis 5KW Hybrid Invertor
Solis quote 2 x WECO Batteries 10.6KW €11000
Option 2
Huawei 5KW Hybrid Invertor
Huawei Quote 2 x 5KW Batteries with BMS €12500
Adding additonal Battery costs Weco = €1800 Huawei = €2400
Eddi Option €650
what if any is the advantage of going with Huawei over Solis ??
Higher output panels are generally just bigger in size. Steel roofs are generally easier to install on (using micro rails). Which could be useful for you. Roughly "standard"panels are 1.1* 1.7 m, you may be able to squeeze 10 onto each roof, maybe.
Mine is SW/NE low slope does suffer in the winter but it starts early in the morning and goes late in the evening on the good days
Oh nice, that's good to know. There is lots of room in the shed.
The shed roof is directly east / west. Same as the roof. In fact the ridge of the roof and shed run in a line. So all the east facing panels would be facing the same way. Same with the west.
I see Energia are advertising they have 550w panels. 10-12 of those would be a decent level of production. Not sure how they are cost wise for the install.
Thats exactly where mine are, Portal frame shed, my inverter is in the barn though, but the inverters can go outside, so inside a farm shed is no issue at all. What aspect is the shed? can you put it on both sides of the roof.
Thanks for the reply.
I'm getting a quote later this week. So I guess the advice is load up on as many panels as will fit, skip the battery, and add the Eddi…..if the emersion is working 😂
Edit: The emersion is working 😄. So that's a plus. I switched it on for an hour and watched the temp. Slowly but surely it went up. Only by about 5 degrees after an hour. I had a look and it's not actually a top down insert but rather a side insert about 3/4 of the way down a 300-liter tank. So has a lot of work to do. And likely limescale is not helping as we are in a very hard water area with our own well.
I had posted in the quotes thread but prob not the right place. This thread maybe feels better as I'm after some tips. I have a few questions that others may have already covered in their own systems that would be good to get some insight into.
Yes 2 inverters is compliant once the total is less/equal 25 amp for single phase. I got a second inverter a month or two before the limit came in, so have a 5kW + 1 kW inverter. When I upgraded to 12kVA connection the connection agreement confirmed that I have a 6 kVA export.
I don't think energia can limit your export? Or have you evidence of this (eg pulling up the ESBN graph and the energia graph)
2 inverters is fine on the nc6 as long as your under the now 25 amps... I don't think you need to do anything.
On the NC6, is having 2 inverters compliant? As in can you have more than one once it’s below the NC6 kW limit?
I’ve to ask the installer to resubmit the NC6 from 2 years ago to reflect the 2 inverters they installed at the time. What they submitted was a 4kW inverter but they actually installed 2 x 3kW inverters (long story of messing during the install!). There was a 6kW limit on NC6 then so I'm compliant assuming they accept the correction from the install date.
Now Energia limit my export to the (incorrect) NC6 limit, which means it’s basically ‘clipping’ on a sunny day. And leaves me no headroom to expand.
Yes
Solis?
Same. When the house load is below 100W, the value falls to 0W.
Perfect, thanks guys, if I set it up on Home Assistant and took the data locally from the logger would I not see it or would it still look same?
That is normal for Solis inverters.
Of course, the graph is scaled to 4kW, so it could be a rounding thing for the graph, but not necessarily that the inverter is not supplying the load, or that zero is being consumed.
Guys, question for you.
Below is plot of consumption, it looks like at certain times of the day (mainly when the house load is very low say 100- 200watts) that the time period either side actually shows zero load which can't be true.
Now if I look back across the last few days since install on some days that period of "flat line" has lasted for upto 1 hour.
I called it out to the installers and they opened a TT with Solis who investigated and said that is normal because load is very low.
Not sure that this is 100% correct as I have some other Tuya switches that can measure as small as a couple of watts consumption?
Just wondered if anyone else has seen this behaviour, or could it be a dodgy ct or even the position of ct?
If I look at the ESBN HDF file on that too I see zero load at times but that would be related to the sensitivity of the Smart meter I guess?
Thanks
It's an optical illusion, the width of those two panels together is 2.25 meters. I think my fence is about 1.9m.
You might be able to affix directly to the concrete posts, they do have rebar in them though.
Swap them out for composite ones and never have to worry about it again 😉
Doh - yes of course.
