99% of the time my inverter works seamlessly however when I plug in the “Granny Charger” to charge the car the app on my phone shows the inverter not receiving any solar, I haven’t checked the inverter to see what’s showing on the screen but will do that today.
It doesn’t happen with anything else like washing machine or dishwasher so don’t understand why the car charging would be different.

Love a good old calculator myself but here you go.
If its within scope or there about, a couple or so extra rails firmly attached to the rafters should do it.
Batteries getting fitted tomorrow 🤞
Still in talks about fitting my solar panels although, I think 🤔, I will be getting 16panels to replace the existing 16 🤞
I tracked down the electrician from the original/bust contractor and he is coming at the weekend to fit an Eastron meter, move the control box for my air source heat pump and give me a price for a replacement fuse box.
These were all on the list of original work and snagging of the original/ bust contractor but I’m just paying for them to get finished so as I can put this sorry episode behind me.
Decking almost there, I totally underestimated the amount of work/ physical effort, it required. I’ve been falling asleep randomly and for a couple of hours at a time.
I am reusing the existing metal balustrade which are powder coated and over 20 years old. They need rubbed down with sandpaper before applying a special primer and top coat.
Photos to be supplied once completed.
45kwh of solar produced today most of which went to the grid, £6:75 returned to my account via Outgoing Octopus 🐙
I would like to thank you Kezo for all your help and advice it been very much appreciated 👍

Anything i post over three lines long please assume it is an article lol.As you say, the usless installer didn’t get paid in full, so why not use some to get the work rectified, just to see the end of it. However, make sure he carries out necessary insulation tests prior to upgrading, as you don’t want to run into a rewire, which could be costly.
My last link goes someway in explaing additional requirements of solar PV close to roof edge.
Interesting I’m just looking at a small house (Newbigging Dundee), with what could be a granny annexe thats the middle of no where, which would suit my daughter when left school in next year. Ironically it would have put me in travelling distance to you but, wifey say she doesn’t want Scotland 😂
Kezo batteries in. I told them it would need two workers to manhandle the batteries, stacked one on top of the other, down and out of their wooden boxes. Yes, only one guy appeared so I had to give him a hand. 22 stone in each battery.
Took him about an hour and a half to complete. I asked him to sort the schedule so the batteries charge from 12:30 to 5:30 each night at cheap rates. “I’ve no idea how to do that” he said bare in mind they have charged over £3,000 to fit these batteries and I’m left to set it up by myself 🤔
Its complete now and that’s the main thing. I’ll be spending a couple of hours on the Sunsynk app tonight getting it set up.
Tell the wife it’s beautiful up here and she would love it.
Yes I will be getting everything completed on the money he is still due but getting experienced competent electricians up here is not easy.

Anything i post over three lines long please assume it is an article lol.£3000?? and they won’t demobstrate or schedule how to set up to customer needs! One things for sure, they wouldn’t be in business long in England or Wales.
Fogstar come configured with the Can Pylontech protocol, which should be ok for Sunsynk, but not sure what BMS you have on the new battery, I would have to look. Becareful, if in doubt by all means ask me but, fogstar is helpful providing instructions over the phone in real time, whils’t you do it.
It really is the the job of the installer during commisioning mate.
Our installer set up the system well should I say sort of, the system eventually failed due to some incompetent wiring, the battery was only working to about 50%. As regards battery charging schedule that was down to me, demo was I have left you a handbook.
After the failure they sent a more competent electrician he required the set up and set up the system correctly, I was considering an additional battery, but after the repair it works so much better so we have not bothered.
The soar/battery industry is attracting some cowboys, lucky we were covered by HIES
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
Extremely suspiciously his quote for the battery purchase and install was exactly the same as the burst company at £7,500 🤔
I’ve managed to set the battery charging from 00:30 till 05:30 and its working fine. The electrician from the burst company is coming on Sunday to fit the Eastron Meter so I will get him to sort it all out.
This having to use an MCS-approved electrician is a racket and its allowing companies to ask way over the top prices for run-of-the-mill work. There was next no difference in prices between the five or six companies I got to price my job.
The electrician coming on Sunday said he would fit the batteries for two hundred pounds but he’s not MCS-accredited so the Energy Trust wouldn’t agree to me using him.

Anything i post over three lines long please assume it is an article lol.What I need to master next is how to force discharge the battery to sell excess electricity back to the grid.

Anything i post over three lines long please assume it is an article lol.I have never forced discharged our battery to the grid

There is growing number of people DIYing solar/battery installs with or without the help of non MCS approved electricians. This number has drastically increased since the ending of the FIT tariff. Whils’t you can’t export to the grid or get funding, what they do become is self suficient.
As a good guide, a MCS registered installer will charge anywhere between £600 – £1000 per day. What we see all to often in the industry, especially where funding is concerned, is a growing number of installers see or believe some or all of that funding is theirs and can become greedy.
Being MCS registered also requires you to have an insurance backed guarantee of which HEIS is one such insurance. However, unlike say gas safe, MCS certificate is not a legal requirement, unless as outlined above.
@Brydo are you using the Sunsync connect app?Yes Kezo I’m using the app but something isn’t right with the install. The app was showing 19,000kw being sent to my home and my Octopus App was showing I was using energy to run the house when the battery should have been. When I go into the app and choose equipment, then Battery, it says “No Data”.
The electrician says he will fix it on Sunday🤞
Oscarmax force discharging to the grid is something I’m looking to do. With battery capacity of 48kwh during the summer months I can send the bulk of this energy back to the grid @ a profit. Its not a major amount of money but around £400 a year on my current Octopus Go tariff.

Is the wifi dongle connected and setup correctly?
So the electrician came to yesterday and fitted an Eastron meter. The system was playing up with one or two things not right. He was here for about four hours doing electrician stuff and he managed to get some things sorted. The system now sends the solar output straight to the grid, but highlighted the fact that I have two inverters and the the original is not a hybrid so can’t adjust it to send solar straight to the grid 😔.
I was having problems charching the batteries to full during the cheap electricity period from 00:30 – 05:30 hrs. He messed around with the settings and was confident he had sorted this but last night the batteries only took 25% of their capacity.
Another problem is that when a load comes on the battery doesn’t cover the entire load and sometimes doesn’t cover the load at all.
I might be wrong but what I was expecting to see when looking at my Octopus Energy app was heavy use during the cheap times then nothing on the app at all as the battery would be covering ALL the use for the rest of the time but it isn’t doing this, I have random loads on the app on and off all day.
If I had a gun and it worked.…….. at least id have something that worked 😤
So he said he’d be checking the system today to make sure it had worked and if not he would be contacting Sunsynk for help. Unfortunately I haven’t heard from him 😔

Anything i post over three lines long please assume it is an article lol.I’m learning a bit about sunsynk inverters and what I’ve been doing is trying to charge the batteries to 100% charge.
So far I’ve increased the amps on the battery settings to “Charge Amps” 125 and “Grid Amps” to 100. The grid amps change has had the biggest impact as my batteries charged to 50% last night when it was set to 75A so hopefully the 25A increase will we me get closer to 100%.
The charge times need a wee bit of time to understand. I’ve set “Time 1” from 00:30 hrs to 05:30 hours to charge to 100%. I had left Time 2 unchecked but, the result of this is that after 05:30 my batteries would discharge to the grid until 20% charge us reached, the 20% charge was set by default I think. I have now set a Time 2 to discharge to 50% by 09:00 just to see if this works, then I can adjust all the time slots that suit my usage pattern🤞

Anything i post over three lines long please assume it is an article lol.The grid charge current (Amps) relates to the DC current (Amps) going to the battery and not the current (Amps) being pulled from the grid itself, so this setting can be higher than your cutout fuse.
For example if you a total battery capacity of 16kW and your grid power setring is 100A
Battery power 51v (from memory) x 100Amps DC =5100w
Grid current 5100w / 230v = 22Amps AC
Thanks for that kezo.

Anything i post over three lines long please assume it is an article lol.Yes Kezo it’s going crazy with this great weather. I’m looking to fill to 100% and empty to 0% each day but I’ve only managed 100% once, no idea why, and I’m not sure about taking it to empty, although I think it can go to empty without doing any damage, so staying at 20% minimum just now until I grow some 🥎 🥎.
The replacement FIT panels are being fitted next Wednesday and that will take me to 14kwp.
Over 50kw produced from solar alone on a number of days so far. This weather is exceptional so I’m not getting carried away.

Anything i post over three lines long please assume it is an article lol.Not a bad looking install at all mate and not too industrialised.
For longetivity Iwould stick with 20% DOD.
Are batteries balanced now?
2 of the batteries are within a Kw of each other the other one is typically 3/4 kw less. I’ve been told the best way to balance them is to fully charge them to 100% and that will do the trick. Unfortunately getting to 100% full on Octopus Go, 5 hours of cheap overnight charging, is proving difficult so looking to move to Eon until I get an EV and charger as Eon gives more hours overnight.

Anything i post over three lines long please assume it is an article lol.I’m not to worried about how long they last as battery technology will have improved massively in five or six years and I fancy a sodium battery/ batteries.
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.Did you increase the charge rate based on calculation I gave, so not to overload main cutout? However, I find EON nextdrive a better tariff overall, as the peak day rate is discounted in the deal and not at the price cap Octopus charge!
Maybe hold off/part discharging a couple of days, to get them float to 100% over the a couple of nights, it’ll be better in the longrun.
I can’t see Sodium batteries ever having the WhKg density of LFP and their size will be much greater to achieve the same density.
