Any personal experience on firman inverters?

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 industries with education, power and grants.

Hi,

The rating of bi-facial is the expected STC rating, just like monofacials.

So if a monofacial 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 s, 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 s. 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

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.

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.

I hope this helps.
God bless you for this detailed explanation

Was a faouni today and it's just 615w 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?

This is not totally true.

If your pv is sufficient to run your load, it works as per design.

let's say one has 4000w and load of 600w.

[quote author=HeavenlyBang post=135534458][/quote]can this work without battery?

Dam5reey1:


Shege promax.. my inverter is still with Sygnite.
I can't shout jare. i am guessing they have a batch with some defects.

Deye would rather not work than to work and blow up.
as a pro, can you grade like 5 inverters from high to low?

As a junior I recommend Haisic
my issue is am in port harcourt and most of them don't have distributors here.
Machiny: 4:48pm On May 23
Seniors please we have too many brand of Hybrid inverters in the market. Btw Haisic, Bread, firman which is more reliable?

What's the difference btw a transformerless and transformer base hybrid inverter?

fuckboys:
it's close to 3 weeks now of active usage and I've never drained the battery no matter how hard I try.

A Fridge and a 43" smart TV with 2 ceiling fans all night has refused to drain the battery. It's very good.
size of the setup?

You are a silly man if you are telling people their pets should have basically a carbohydrate and protein diet, dogs need vitamin and minerals too VEGETABLES they are bloody omnivores similar to us

You are extremely lucky your dog didn't just become diabetic feeding it that much carbohydrates and salt they're not like us mate they convert carbs to sugar faster you are going to gets dogs killed telling innocent people to feed the dogs that crap
Did you see where I mentioned multivitamins

Mate im white and living in Nigeria and have been keeping dogs since I was 5 years old all of my dogs have made it to 17 years old minimum and you are a silly man if you think walking a dog is adequate exercise for a dog

The average human walks 2mph but the average dog is walking 4mph

You can walk a dog 2mph all day long and that is basically no exercise to it

How you treat dog here is cruel and unusual torture and animal cruelty, you want your dog to live longer

1) get it running off the lead for a few hours a day

2) feed it human grade grain free meat and fresh vegetables not rice or pasta and kibble is useless

3) if male dont castrate it

Its that simple
you been white makes you know better? Answers is no. Me been silly thanks.

Just 72 cells
10p7s = 70 cells.
should give same power as the 12v I guess? because from your 12v pack there is total of 72cells,

Fenrir:


What the hell is wrong with you?

Why on earth are feeding dogs that crap?

For 1 the sodium levels are way too high in it even for humans

and 2 it lacks any kind of nutritional value a dog needs, all it will do is fatten the dog up and cause health complications later

But what do you expect from a nationality that will eat dogs if times are hard or you are just hungry
sodium is in the spice not the noodles itself, and we don't use the spice. 2. We always advice pple to get protein source as to balance the meal. Walk your dog regularly and use multivitamins and your dog is good to go. 3. We supply veterinary shops handled by doctors and should know better.4 The dog you see there is 14yrs old, what more can one ask of?
Machiny: 4:44pm On Apr 25

Testing at the moment
why didn't you go for 24v since you have enough cells?
