Then its worthless, if you have a house fire the insurance will do its best not to pay out.
Just a warning is all.
Am i buying a decent hybrid and is it legitimate advice needed,

I disagree. A "new circuit" connected to the CU is notifiable under Building Regs Part-P.
The wooden box does not meet BS7671.
More importantly, you have just put a DIN-rail mounted breaker in a random enclosure with bare mains connection screws exposed. You or someone else could easily touch those connectors.
It would be bad enough to kill yourself, but if you have children visiting you are beyond crazy.
A new circuit or a complete rewire the homeowner can undertake the work qualified or not the legal term used to be "competent person" but note I said the work has to have an inspection and testing certificate.
Part-p used to be a joke when I stopped working 8 or so years ago there were far more cowboys undertaking work with part-p than legitimate electricians the best standard was always an niceic contractor one with a commercial ticket was even better, this often superceded part-p atleast back then.

How are the panels wired, all in series?
How did you measure current?
I'll assume you used an ammeter to short out the array, measuring Isc.
I'll assume all panels are wired in series.
Voc of the series string will be the sum of all Voc.
Isc of the series string will be Isc of the highest current panel.
Key here is that when series string is shorted, current forced through lower current panels goes through their bypass diodes.
Similarly, a panel with half-cut panels is internally wired something like 2p17s + 2p 17s + 2p 17s
If one half-cell gets shaded, taking out production of one 17s, it will be 2p17s + 2p17s + 1p17s
Voc would be 51s
Isc would be 2p
For a more extreme case, if you took 19 panels and wired 10p, the others 9s, and connected 10p in series with 9s,
Voc would be 10s
Isc would be 10p
Power would NOT be 100x the wattage of one panel. It would not be 19x one panel. It would be 10 panels.
Anyone know what size circuit breaker I need for my solar panel array, and if you could include a link for Amazon thanks
I have 8 X 415 watt solar panels connected in series, ive include a picture of the solar panel specs
I'll take that one, it's easy.
You don't need a circuit breaker.
Yes, notifiable under part-P, so can self install, but will need building inspection or part P sparky to sign off (not just for insurance purposes) - which they won't with the state of that switch for starters.It is kinda only for liability and insurance purposes otherwise why notify them at all, the electricity board will likely not care and just presume it's all got certification.
Though I'm surprised that your claiming part-p is such a big deal now, back 10 years ago every kitchen/bathroom fitter and their grandma's had part-p certification it was pretty much worthless then. Do you know highly qualified people in the electrical industry that you can ask about their take on part-p? Or any UK EE people reading this is it really any more valuable now than the toilet paper it used to be?
No worries

People say this all the time. Do you have any evidence to back this statement up?
Currently there all wired up in series under load there now producing 3400 watts, on an open circuit there producing 4400 watts,
I've spoke with a couple of solar installers and they both said they would never wire 8 X 415 watt solar panels up in series, they would normally split them, into two groups, but they never went into detail why, ?.
6 panels are the same 2 panels have a slightly higher amperage output by 3 Amps but slight lower voltage output by 3 volts.
Where I was thinking about putting a circuit breaker was between the hybrid inverter and the solar panels.

Side note if your local energy supplier or guy comes to read the meter you will likely get in some trouble with the wooden box if they need to check isolators, best bet is to get a proper enclosure of some kind tlc direct was a good online wholesale outlet if you don't have a local one. Atleast then spending a few quid on a box you might not get noticed and end up having to pay 100s or even 1000s.No worries
I'll get a metal case soon thanks
Not necessarily the fire aspect but I worked on a job with a kerosene stove that someone installed a main line that was soldered. The kerosene ate through the solder joint and went on to empty 1000liters or more into the ground. Because the install wasn't signed off by a certified oftec engineer the insurance didn't cover the £300,000 bill to remove the polluted soil

Open circuit they will produce nothing....there is no load hence no consumption.
I give you 10/10 for effort and 0/10 for comprehension.
Apparently another of those youtuber type who are satisfied with "hey it lights up and works, job done"
AND SERIOUSLY, WOOD BURNS, DON'T PLAY DUMB.
Building regulations are there for safety and it is government legislation, nothing specifically to do with the DNO.
The requirements are there to prevent deaths and serious injuries. Recently a pub owner was sent to prison for the electrocution of an innocent 7 year boy. See..

Seven-year-old Harvey Tyrrell was found unresponsive by a friend outside the King Harold pub in 2018.

I am not trying to be awkward about the OP's postings for no reason - I genuinely believe the OP does not have the skills or knowledge to be creating a safe environment for herself, family or anyone visiting the property.

Apparently some people can't accept that they are wrong or doing something dangerous and start lashing about like this when they are not hearing what they want to hear. Hey not my property, not my life, not my problem, over and out.

I find it very odd to get mad about a conversation on safety.
Sure, OP may not care that a shed burns down in the middle of nowhere, but doesnt understand why we cant just smile and nod in agreement.
i find it very odd that I've been insulted several times for no good reason, anyhow im not happy with the edecoa inverter, its a piece of crap I've sent it back, i noticed the specs are not was advertised so im of to pick up a
Sunsynk SUN-3.6K-SG01LP1 very shortly hopefully.
that would be good thanks
hi I'm going for the sunsynk 3.6kw, did you wire yours up yourself

Yes, I did, but had help from an electric engineer and studied the electrical code from Brazil to do it.
So far so good.
What’s your power needs? 3.6kw is very limited. How will you integrate it into your house distribution box?
I’m saying that because there are some ports that have bypass current limits; the AC passthrough current limit is 35A from the GRID port to the LOAD port. And you will have 16A available while off grid.

3.6kW has its advantages in the UK. Under code G98 you don't need to apply for permission to connect it to the grid, you only need to notify the network company within 14 days of commissioning. Over 3.6kW comes under code G99 and you need to get permission in advance.
Of course you still have to make sure all the relevant electrical codes are followed.
No probs
thanks for the reply, It's coming tomorrow I'm getting it less than half price, 450.00 should be about a thousand new, it's of a roofer I know, he's decided not to go ahead with installing solar panels at his house now so he's letting me have it for 450 brand new. I could do with a few tips, can I give you a buzz tomorrow I'm holding out for a couple of months a friend is bringing me one of these back from Holland brand new for 600.00

I'm just grid tying it to the mains only for now
. until my super duper battery comes, I'm not risking connecting lead acid batteries to the inverter, so for now it will just be grid tied for 3 months at most, no batteries
