Then its worthless, if you have a house fire the insurance will do its best not to pay out.Didn't get a certificate i payed 40.00 for an inspection.
Just a warning is all.

I disagree. A "new circuit" connected to the CU is notifiable under Building Regs Part-P.OP is working on their own install thats totally fine in the Uk and doesn't go against any regs or part-p as far as I'm aware
The wooden box does not meet BS7671.Wondering why doesn't answer what's wrong with a wooden boxes,
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.I disagree. A "new circuit" connected to the CU is notifiable under Building Regs Part-P.
Hi correct it was open circuit reading, but why the big jump between different arrays when setting the panels up ie only 3000 watts when combined in series and parallel and then 4400 watts when combined in series only
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![]()

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.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.

Currently there all wired up in series under load there now producing 3400 watts, on an open circuit there producing 4400 watts,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.
I'll take that one, it's easy.
You don't need a circuit breaker.
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![]()

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 soilPeople say this all the time. Do you have any evidence to back this statement up?
Open circuit they will produce nothing....there is no load hence no consumption.all wired up in series under load there now producing 3400 watts, on an open circuit there producing 4400 watts,
Building regulations are there for safety and it is government legislation, nothing specifically to do with the DNO.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.

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.
I suppose you've never used YouTube in you life, right yeah because your the expect installer who sits around a do it yourself forums waiting like a predator to pounce on people, with your expert knowledge, yeah right since when do fully qualified solar panel installers hang about in a do it yourself forum spouting there gobs of to people with lesser knowledge,
I can't think of any genuine tradesman, who would join a do it yourself forum in his or her profession just to insult people,
Go and get a life. And shove your attitude with it.
I find it very odd to get mad about a conversation on safety.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.
that would be good thanksI 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.
hi I'm going for the sunsynk 3.6kw, did you wire yours up yourselfI would go with a grid tied hybrid. Deye is not sold in the UK, just Sunsynk which works the same.
IMHO, I would go with a “buy once, cry once” approved solution.
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.What’s your power needs? 3.6kw is very limited. How will you integrate it into your house distribution box?
No probsYes, 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.
I'm just grid tying it to the mains only for now3.6kW 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.
