ksmart027: Thanks for the address, very close to my place. For the bread inverter, do you mean the are noisy? I mean there fan compared to fireman? And do fireman also have 3.5kva? And what is the pv input?? And i saw the bread spec? Does it mean the spec are false. No vex for my too much questions.
this is from the booklet they gave to me. Seems they have different kinds
ksmart027: I thought bread 3.5kva have 4000 pv input?? Please where's there office in ph?
16 Damiete Drive, off Full Gospel Road, By Odili Road, Port harcourt . 3.5kw is 3000w max pv, while 4.2kw is 5000w. Thinking of firman my issue with them is ordering online but has service center in ph, but no walk in store for purchase. Noticed firman is almost noiseless
fuckboys: it’s a new product, bread inverter by hinen. Been 3 months now since I started using so not sure about the reliability yet.
There’s this guy on YouTube named solar God, most of his 12v/24v installations are bread inverters. I trust maybe he’s at peace with them bread inverters.
Have been to bread office here in port harcourt. But am looking at a 3 to 3.5kw that can accommodate my 3700w pv
fuckboys: my inveter never goes off, only time I off it is when I'm traveling and spending days away. Normal daily hustle it's always on till evening when I come back.
Ttalk: Growing economy is beyond container economic reasons and government policy covers so many areas beyond profit making.
Israel developed her agricultural sector not because it has comparative advantage but because it is a security leverage to develop mechannised agriculture in a face of limited land and hostile neighbors.
Many of those items you listed above can well be developed and turned into profitable venture.
Malaysia doesn't have a better comparative advantage in Palm oil production until they develop that crop out seed they got in Nigeria.
Nigeria leaders are bad but it would be worse with the kind of mindset you and your people have.
Years of importation have killed the innovative and entrepreneur talent of Nigeria people, your traders mindset is not same mind you use to build thriving industries, you are used to instant gratification but building industry and a nation requires delay gratification
people prefer buying nigeria wires, was it because govt stopped importation of foreign wires? Govt should support industries with education, power and grants.
The rating of bi-facial is the expected STC rating, just like monofacials.
So if a monofacial panel is rated 615w its bi-facial counterpart is also rated 615w.
Bi-facials then have a ‘potential’ power gain on the rating.
For example, I have 6 x JA 605w bifacial panels, they are rated to give me the 605w each, but I can get extra power of up to 653w each from bi-facial gains.
Here is my experience, I mounted it on a roof (regular angled roof), my max expected power at STC before bi-facial gains should be 6 x 605w =3,630 W. Then I can potentially get higher due to potential gain.
I actually get up to 3897w with them, so 649.5w each for 605w rated. That means I constantly get the bi-facial gain while mounted on roof.
The main thing is that your roof should be refective (etc aluminium) and from a white colour to like a light shade of gray etc, those are the roof colours that’s can reflect sunlight on the back of the panels. Black roofs might not work because black and darker colours absorb light and do not easily reflect.
See the attached picture, the first bar on the chart, notice the Pmax 3897w.
would you advice the bifacial over the mono with your analysis, since they are same price? Many have talked down on the bifacial
BigDickProblems: Yeah that’s correct. One side is positive and the opposite side is negative. I was like you too 😁
Those 24cells are all connected in parallels already, meaning that the positive terminals of each cells are welded and connected all together, and the negative terminals are connected all together as well. That is called 24P. Then each of them will be connected in series to form 3 series. This is why it is called 24P3S. And for this to work, you will need a 3S BMS (I.e a BMS for 3 Series connection)
To help further (I don’t know if it’s necessary though. But I love maths😁)Now let’s do a quick maths: Assuming each cell has a rating of 3.7V and 3.2Ah
The 24 pieces that are all in parallel will give: = 3.2Ah × 24 = 76.8Ah capacity and 3.7V.
Nb: When you connect in parallel, you increase the capacity (I.e the Amps) but the voltage doesn’t change. This means that the 24 cells in parallel has a constant voltage of 3.7V but Ampere of 76.8Ah in total.
Let’s continue. So now that you have 3 units of 24Parallel cells, it means we have 76.8Ah 3.7V in 3 places. He will go on to connect the 3 of them in series. Let’s do the maths.
Remember that connecting in series increases the voltage but keeps the Ampere constant, so let’s add up the 3 voltages: 3.7V + 3.7V + 3.7V = 11.1V Total capacity will then be: 11.1V & 76.8Ah =11.1 × 76.8 = 852.48Wh
But ofcourse, the capacity might not be up to that at the end of the day.
Was a faouni today and it's just 615w panel they have. Both BI facial and MONO facial are same price. Which is preferable? Also a transformer base and non transformer base hybrid which is better?
