3.5kva detailed installation with explanation loading....

saxwizard:
why did you choose a 96v inverter..


i believe there are other 5kva inverter with maybe lesser or higher voltage..



you should also do a break down of loads on the inverter.. and average run time






nice jobs sir...

explanatory and detailed more jobs to come...

i will explain soon... the explanation to this question is very lengthy..

1. The higher your volt the quick it takes to get to 220v, you will agree with me that it will be much quick and less stressful for a 96v to attain 220v than a 48v inverter..

2. The higher the volt the more battery the inverter can take and it result to more energy stored..

3. I will add this point later, it's the most important point, it about amps.. keep following sir

More 8 batteries would be added to the previous 8, making it 16...

The other 8 batteries would be connected in series...

When the client provide more funds for the other 8 i will update this thread...

OgogoroFreak:
What's the total cost if setting up this system?

i really don't wanna talk about money on the thread not to discourage people from installing..
Chat me up for the price...
Hope you nor dey vex?

dragnet:
your wiring doesn't look tidy.
how did you combine the solar panels? did you use a combiner box? what wire size/rating did you use to connect from solar panel to charge controller ?

Pardon my late reply... the election matter tire person jare..

Thanks for spotting the wiring, i was hoping no one would asked but since you've asked.

Electrician is working there too, trying to segment the house load to 3 more AVR, the power there is really bad.
The Generator set would still be mattered close to the solar installation.
Work is still on going...

For the solar panel connection a combined box was not used.
Please revert to the hand drawn schematic i uploaded early.

A positive wire ran through all positive panels terminals, same as the negative wire too, down to the charge controller.

6mm wire was used for connection of the solar panel to charge controller.

10mm wire was then used from the charge controller to the batteries.

@dragnet the sizing wire is 6mm not 4m, sorry about that.

We had to used an AVR (Automatic Voltage Regulator)

AVR>>> Is to balance the voltage from nepa before it goes through the inverter. The rating of the Avr is 140volts to 240volts, so if the power that phcn is providing is 140volt the Avr will boost it to 220volt.

That's the black box below.

The area the client was staying has power issues, the power is not always steady, it goes so high and very low..

The AVR had to be used for effective charging of the batteries from the main (Phcn/Nepa)

Note: Both Solar panels and Main (Phcn, Nepa) can charge the batteries too, including Generator...

Feel free to ask any questions
Abeg i nor be island oh, i don't know everything, am still learning every day on every project

Other Expert can add to this thread.

Thanks

Check the batteries below..

The first picture shows when the inverter was been tested to ascertain the state of the inverter before installation.

The battery were connected in series to get the required volt for power up the inverter

That last picture was after the installation at the client house..

The battery used are jell batteries, they can last for 2-8 years depends on usage..

If a battery is used flat frequently the life span of the battery are always reduce...

Check the inverter below

The inverter used was a 5kva 96volts sine wave
It's a digital inverter but does not have a backlit to see the readings at night.

It was a bit stressful carrying the inverter on the battery rack..

For this inverter to be powered on we need to connect 8pcs of 12volt battery in series

8*12v=96volts

The voltage of an inverter will determine the number of battery you need..

saxwizard:
you should not skip the calculation part.,.its important i guess...


between nice work so far


also kindly state brand of charge controller solar panel inverter etc used

Sure i will do that...

I'm leaving most things to let others ask or make their own choice though

saxwizard:
kindly state the kind of connection for the panel

series or parallel

thanks

Thanks for the question..
I intentionally skip the connection process not to scare people who don't know about solar away.

It's a series parallel connection.
I made mistakes in the ratings initially, the panels are 200w 9amps 30v rating...

We connected 4 panels in series 32/4=8 and linked them in parrel, thereby increasing the panel volt to 120volt and 72amps(we had to increase the charge controller to 80amps to accommodate increased in amps that normally cause by high intensity of the sun)

Series Connection Linking positive and negative together thereby increases the Volt while amps remain constant.

Parallel Connection Linking poistive and positive or negative and negative together thereby increases the amps and volts remain constant

Check my hand drawn schematic diagram below (That's the connection we did for that installation)

That's the charge Controller below
This is the first time we used a Power Wave controller and it has proven to be working well.

The purpose of charge controller is to maintain a steady charging of the battery so it won't over charge or discharge thereby protecting the battery from failing(spoiling) quick... The battery temperature and percentage can be monitored from the charge controller..

The Charge controller is 80amps(current) 96v(volt)

Installing the Controller was pretty easy, just screw the for edges.

This Power wave Controller got just Panel input(wires coming from panels) and battery out(wire leaving charge controller to battery)

Note: Your battery determine the charge controller Voltage, while the solar panel determine the Amps(Ampere)
I can explain in details if you want..

Installation Done in Delta State Capital GRA

5KVA installation Process
same as 5000 watts installation.


32 panels installed
Each panel has 200watts, 30volts and 9amps capacity
Installing 32 panels, means it will generate 6,400watt
Watt means power
32*200watt=6,400

Please i don't wanna bore my readers with lot of calculations.

I will be showing the charger controller used, inverter and batteries

Welcome to a informative thread for prospective solar installers and those that already got it.
I'm Terry a Solar Expert and i will be updating most of my completed solar projects here.

This thread is to share my experience on the installation process i pass through while installing Solar.

Please take note that everything would be broken down to enable others from various field to assimilate quickly/easily.

The things that you will be seeing often are
1. Panels
2. Charge controller
3. Inverter
4. Battery

madman. You go dey refresh am every one min

dharmhie:
good evening house. pls I need help on getting the battery and solar panel sizing for a 10kwh loadings.

I have two 250ah Mono panels
I wanna know how many 200ah batteries would be needed, and how many panels to join to the ones I have and rating of the charge controller.. thanks

The amount of your battery bank depends on the voltage of the 10kva inverter you wanna buy or have....
When the voltage is known, then the charge controller can come in before panels...

Holla me on WhatsApp later jare. Battery is low.

Thanks oh

nkhay:
No mind the yabaleft patient. He's been contacting me with different numbers to buy his cashapp funds he scammed from Innocent Americans, whenever I demand for proof of earnings, he'd say some nasty things and take off. So I stopped replying him.

He contacted me some days back and I didn't respond so, he resorted to slandering my name to make sure I lose clients. But he's late to the party as most legit nairaland traders are already grouped on WhatsApp because of scammers like him - Thank God some traders envisaged that lunatics like him would surface in the future, forcing people to partake in their cursed lifestyle.

They're now so confident that if you don't buy from them, they'll resort to threats and slander.

I still don't get why he hasn't been banned.

You i know! Him we don't
Go into the world Nkhay and sell/buy more funds..

Nkhay borrow me $25 from my $50 na
