I have been a very silent reader on this thread but felt the need to comment

On Amazon before u buy a product u click on the reviews and read user experience with the product and after sales services which helps u make up ur mind on buying or not.

So we should all be encouraged to air our costumer experience so others can make up their mind before contacting any seller.

Thanks.

Please I want to make several inquiries.

I have a colleague who wants to mount 20 pieces of solar panels on the roof but the Architect is cautioning against it on the premise that the roof was designed to carry its own load and not to carry other superimposed load.

Each solar panel weighs about 18.5kg according to the name plate so 20 panels is about 370kg total dead load excluding added load on a windy day.

Pls for the gurus in the house who have carried out several installations is there an specific design of the roof member trusses before mounting the solar panels on them?

And

How safe are they mounting that amount of panels over the years (10years time)

Thank you all.
Re: Solar Energy, A Complement To FTA by makavele: 5:47pm On Nov 04, 2018
Pretty small unless the roof was built with
substandard materials. 5 average men of 80kg weight is 400kg. Are you saying 5 men standing on the roof will damage it? They can stand for eternity. A man standing on the roof puts more pressure than an equally weighted panel. Force over area = pressure .

TLDR: Take your mind off it .

Ask the architect how long 6 full grown adult can be on the roof without it coming down.

Modified: just noticed that your post had already been properly responded to above.

I am a DIY solar installation enthusiast, I have been a able to successfully executed over 8 projects, but having come close to install 20 panels of 325watts 30v to a luminous 10kva 180v. How are the solar panels connected to achieve 180v output.?

I've been Kiekie's client twice and as recently as this evening , I received my panels way billed from him to me. (Not minding he wasn't impressed at the price he had to let it go). grin
Past delivery of Panel roof rails, clips , remote display and breakers had all been done in the past without even as much as a physical handshake with him. I still remember his "throw in" gift of a temperature sensor which wasn't part of our bargain then.

Well I'm always of the opinion that the customer is always right... as much as I may not complain about he's sincerity, other clients may be displeased if they find any weakness in his dealings.
That being said,
Same ads posted here is what got my attention to get these panels purchased from him. But if the forum agrees that its a problem then it provides an avenue for more ideas doesn't it?...lets have a weekly black Friday for ads...whats wrong with a little innovation grin

For me...honesty and mutual respect comes first...other emotions that may lead to bad mouthing someones business gets relegated to the background or sorted directly with the person in question to get it off my chest. Many gurus here do refer newbies to reliable sellers without referral bonuses wink
I'm sure there will be more past and present customers like me that will say he's been a reliable supplier /retailer... and personally the complaints might just be isolated events that will eventually be given a well soothing explanation.

“You can please some of the people all of the time, you can please all of the people some of the time, but you can't please all of the people all of the time”.....thanks kiekie.

Thanks for the patronage Sir !

I am a DIY solar installation enthusiast, I have been a able to successfully executed over 8 projects, but having come close to install 20 panels of 325watts 30v to a luminous 10kva 180v. How are the solar panels connected to achieve 180v output.?

This question is seriously flawed. A lot of things are confusing about it.
You have 20x 325 W; 30V on the roof trying to achieve 180V ouput to an 10kv inverter.
What happened to our lovely brother, int the middle, the charge controller
The last time I checked, the panels on the roof are arranged in specs with the charge controller; and not the battery or inverter.
The "amount" of panels (emphasis on the word, amount) is chosen in accordance with how large the battery bank is.
The inverter does not run off the panels. Except in the microinverter world. Another league of its own.
Hell yeah, if each panel has a VOC of 30v (which i doubt); You could as well, string 6 panels in series and get 180V yeah; then parallel another 6 twice, to make a 6 by 3 config, with 2 panels being redundant.
Try this and blow up the charge controller . . Except it is rated to handle 180V of VOC.
You wanna use multiple charge controllers, then you gotta split the array too . .

Well, what do I know? Too much Netflix these days have gotten me quite solar-rusty.

So you should perhaps rephrase your question again or wait for the other gurus to come help both of us out.

Nobody has the patience to go through this kind of adverts line by line.

How do you think this thread will be if every marketer resort to this strategy.

You can copy my line below:

I remember quite early this year. I raised a very strong objection towards spamming the thread with adverts and the rest of the "solar' caucus turned a blind eye to my posts {complaints}. I was so pissed, I had to copy another marketer's ads (zeestone) and was posting it in quick succession, spamming the thread rather rapidly.
And Kiekie (who I had the complaint against) would continue to post, and I would not relent either, I wasn't marketing for zeestone99; I just wanted to show that if we continued, there would be practically nothing to read except ads. This isnt Craigslist or eBay.
I gave up after a while.

The inverter is not a hybrid rated at 10kva 180v, but want to configure in solar array 18unit assumed to be 24v, the battery bank is 15units of 12v 200AH battery ring in series to achieve 180v. Hence I am looking at a maximum number of panels 18 units, and a fangpusun 100amp 180v rated solar controller. My question how to ring the 18panels to arrive at 180v output from the panels to the charge controller, I am assuming ring 6 sets in series by 3 and connect all 3 positive together and 3 negative like wise. What is your opinion?

What is the VOC Rating on your CC to start with..?

Note you can't charge 12V battery with 12V VOC panel

Hence you can't be calculating towards 180V..

If VOC is 250V or higher Simply do 9S2P

9 panels in series connected in two strings

It would be too much effort to quote all deserving posts (literally every post made) on this 180VDC VoC thingy.

I'm not really contributing. Just wanna point out a few things.

- 325W panels having a VoC of 30V are rather uncommon. Be sure you're not quoting the ImP.
- Victron and Midnite make 250V MPPT charge controllers. MorningStar has one doing 600V. Most others do 150V or less.180V CC are not so common. Think forward to future maintenance and support if you're using a product uncommon neither here nor elsewhere.
- off-grid hybrid inverters are likewise either 150V and below or much higher (typically 320V and above). Smaller ones exist with your VoC.
- in anything you do, safety comes before economic viability and ease of use. Unless tangled in cables or otherwise firmly grasping a live wire/device, 180VAC is unlikely to kill an adult. 180VDC almost certainly will. Have you considered the cost of the necessary accessories for grounding and fault protection?

Unless your panels are really far from your CC, there really isn't a justifiable reason (asides personal desire) to exceed 150VDC. That's the sweet spot for transmission losses and safety of cable handling.

This is very false. Electricity be it, AC or DC above a certain voltage will kill you. While it is the current that kills and not voltage, but after a certain voltage there is enough propensity to deliver the current.
A 12V battery practically does no harm when you short-circuit the terminals with your bare hands, because 12V is too small too push the current.
But touching a 240V outlet will zap you, because there is now enough potential difference( 240 live and 0v groun) to push the current.
120VAC will do more harm than 120VDC. They will both dissipate the same amount of power in a resistive circuit, however, in an AC circuit, 120VAC is not the peak voltage. Due to RMS, the peak of 120VAC is somewhere around 170VAC and the peak of 240VAC is somewhere around 365VAC. So you see for the same amount of power, the AC has the propensity to deliver far more instantaneous current due to RMS peaking.
Also, the human body can resist DC much better than AC. The human body has both capacitance and resistance. As current oscillates, a capacitor (now the human body) is less inclined to slow it down. DC doesn't oscillate at all, thus more inclination to slow down the current, This leads to high Impedance.
AC on the other hand oscillates rapidly, so the Impedance is very low, which means lower resistance, and more current can travel through you. This is why even 80VAC will zap you, whereas 80VDC, might sting you.
Finally, VAC causes heart fibrillation. Since we know that AC is always oscillating, when it reaches the hearts, it f*cks with the muscles, making them move out of rhythm. This is called fibrillation. DC doesn't oscillate, so it if unluckily reaches the heart, it just stops the heart.
And a fibrillated heart poses great danger than a stopped heart.
The most important thing is that both will kill you if the voltage is high enough to drive current through your body and depending on the point of entry (contact). But the AC has more potential to kill, pound for pound.
And this was the argument point for Mr Edison in his fight against Nikola Tesla and yes he was right . . .

Boss,

Please confirm the following;

1) You have a 10kva inverter with 180vdc nominal voltage - Yes or No?

2) You have 15 pieces of 12v batteries connected in series to make 180vdc nominal and you are using these batteries with the 10kva inverter. Yes or No?

If the above are true and you wish to keep your battery and inverter setup, then at a minimum you will need a charge controller with higher than 180v operating voltage - at least 210v to 230volts operating voltage rating to maintain your batteries properly.

Since you mentioned a PWM CC you will be needing to have your panels setup in series to make up at least 260v (PV Panels must provide at least 17.5vdc output at the panel for each 12vdc nominal of battery) for you to have any hope of getting enough voltage to your batteries.

BE SURE THAT YOUR CC CAN HANDLE THIS KIND OF VOLTAGE BEFORE YOU PROCEED!!!

I have a running joke that it requires a person with solid technical skills to make PWM work efficiently in a large system whereas any average Joe can string together a reasonably functional MPPT system - in your case it may be worthwhile for you to look at an MPPT CC - BUT since the sweet spot for these systems is 48v you may need to jettison the 10kva 180vdc inverter and get a 6kw or bigger 48v inverter

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 11:38am On Nov 05, 2018
I suggest that you do a load assessment for this client/location to determine what their equipment loads and power needs are - with this information, you will know what size of inverter will be right for the job.

Most people tend to use systems that are oversized for their needs and this is both wasteful and inefficient.

Finally, you should definitely look at an MPPT based design for this project - I am getting a bit old in this business and I have yet to see a worthwhile PWM CC that excels in the kind of high voltage scenario you have described - the marketers will offer you many seemingly attractive PWM choices - it is doubtful if you will actually find one that delivers as promised - the more likely end result is dead batteried and dissappointed clients who now believe that solar does not work.

If you are using sukam or similar Indian CC then the CC is rated at 415 VoC so you can safely put 9 325 watt panels in series.

However, I would advise using the linemates gloves while working and Schindler 250 V DC surge arrestor before the DC breakers/fuses to avoid both life-threatening issues and serious fie incidences in future

or better ask somebody who has working experince of HV volatges like ex NEPA electritian

The 80 - 270 is nice...
If "NEPA" isn't delivering 220-240; then rest assured they are delivering 80V
