Thanks Muhammad really appreciate your wonderful comment and by the way I am the camera man and the editor.

Thanks Austin really appreciate it

Thank you so much bro really appreciate the positive energy

@@DNC2.0 Im studying solar now and this video really inspires me! Thanks bro

@@wnderjuan2344 you're welcome bro

Thanks mate always happy to help

Thanks sowe really appreciate it and maybe it's all because of the calculations we did in class 😂

Thanks bro really appreciate it but we're located in the Gambia 🇬🇲

You're welcome bro

Thanks mate really appreciate the possitive comment 👍

Thanks really appreciate it but which country are you located

Felicidades jóvenes buen trabajo

18KPV can only be used in the United States and Canada or countries with 120v/240v and 60hz split phase. If you live in Nigeria, that inverter isn't for you. You need a 230v single phase inverter with 50hz. You need an inverter with L1 and Neutral. Not one with L1 and L2. Understand what you are doing before buying something you won't be able to use without a transformer.

Thanks mate

Thanks! 😄

Thanks mate

Thanks man

Thanks, will do!

Thank you too, and you're welcome

The bricks are custom made cement bricks with a length of 40cm, width of 16cm and a height of 19cm. To make the bricks you should make a custom made frame using these measurements then then mix the cement with sand and pour it in the frame you made then you take two bolts and put the heads in the wet cement, and measure the distance between the two bolts for consistency on the other bricks. After you made the bricks you measure the point of the two bolts on the bricks and drill the same measurements on the metal bars so that you can easily slide it in then tightening it with a nut securely. Alright i guess that answers your question and thanks for the positive comment by the way. Peace out✌️

Thank you for your reply @@DNC2.0

Its a 4 post power distribution busbar. You can search it on Google for more information, and thanks for the comments

Thanks bro really appreciate it. The concrete bricks aren't fixed to the roof floor but instead we just placed it because the weight of all the concrete bricks combined is enough to securely hold the panels.

Thanks

Yes, of course Oh alright thats pretty cool the dimensions of the frame are as follow. The Base angle bar is 1m 76cm, the long vertical angle bar is 80cm, the shorter angle bar is 40cm, and the top sloping angle bar is 1m 76cm. Keep in mind that the panels we use are 1m 96cm × 1m6cm alright i hope that helps

Thanks

Thanks bro

Thank you! Cheers!

@@DNC2.0 you are welcome to Pakistan 🇵🇰

The dimensions of the solar panels are 1960×1060×35mm or 196×106×3.5cm

Thanks mate, I don't think it can

I didn't use any software for the wiring diagram. I draw it myself

They were custom made bricks with bolts sticking out to easily tighten the metal frames on the bricks

The RCD is installed in the main distribution box which unfortunately wasn't shown on camera

@@DNC2.0 Even at that , the inverter should have its own RCD and this is important to show in your installation videos so viewers are convinced you know what you are doing and that you take safety importantly...there should be an RCD , a Type B or Type F , after the inverter before the Distribution Board

Naija una too the find error abeg

@@Opsolar it is from the errors and feedback, improvement and better delivery of service is generated... Errors and feedbacks are beautiful things

Thanks for the comment mate. The panels are not directly connected to the inverters but instead they're connected to a Surge Protective Device first before reaching the inverters

@@DNC2.0 i see. thats what im talking about there is only protective device between the two. kudos

Thanks bro for the positive energy. Yeah the first DC breaker serves as a fuse to protect the inverters from over voltage ⚡️ from the panels incase of surge,and the second one just serves the purpose of an isolator

Which calculations are you refering to

No the the inverters were connected in parallel to increase the overall output power and the batteries as well were connected in parallel to increase the overall capacity. They are all collectively controlling one big load

@DNC2.0 oh I see. Thank you

We wire the batteries in parallel to increase the overall capacity. Each battery is powerful enough to power a small house

Oh alright thats pretty cool the dimensions of the frame are as follow. The Base angle bar is 1m 76cm, the long vertical angle bar is 80cm, the shorter angle bar is 40cm, and the top sloping angle bar is 1m 76cm. Keep in mind that the panels we use are 1m 96cm × 1m6cm alright and no need for you to pay bro am here to help anytime you need me

It's a 5000W, 48V, 119A Felicity inverter

Thanks mate

Yeah all the inverters are connected in parallel then to the distribution board

So all 3 inverter give single phase 220v , what about if i connected each inverter to its single phase so i get use in 3phase house . Is it possible ?

Gambia 🇬🇲

We are located in the Gambia but if you need our service we can come and install for you. The batteries are each costing about $1810 you can check it on alibaba for more information

I don't understand the que3

Thanks

We use it for added protection

You should have used double SPD instead, if you are actually keen on Added protection. Peace!!!

No you can't get up to 5000W in a 5KW inverter because you have to take into consideration the power factor which most inverters have 80 percent of or 0.8

They aren't 100% efficient, just FYI. Most of them are around 90-94%, efficient, which is good.

They also have continous and surge ratings. Inverters lose efficiency because of heat, conversions, and how much power they take to run. A 5kva inverter can never give you 5kva. The highest it can produce at its best is 4.5 - 4.8kva. Except the manufacturer is accounting for those inefficiencies.

Knowing Felicity, I can tell you their claims are mostly BS. So their inverters will be less than 90% efficient. They aren't honest.

Any appliance rated in KVA is just a marketing strategy to make the appliance look bigger than what it actually is, after all, your TV eg is not rated in " KVA but WATT... Most KVA rated inverters have a power factor of 0.8 so, for example , an inverter rated at 5KVA PEAK WILL PROBABLY BE A 4KW or 4000Watts .... So when buying inverters , look out for the ones in Watts not KVA. Most inverters made in Europe or for European Markets are rated in WATTS and they also come at huge prices

Yeah we carefully studied the movement of the sun to efficiently install the panels to harvest maximum sun rays

We bought 24 panels of 450W. 3 inverters of 5KW to be later connected in parallel to increase the overall output power to 15KW. 3 batteries of 15KWH 51.2V each to be also connected in parallel

You can get it by ordering it on the interet or getting it from an electrical shop

In the Gambia 🇬🇲

Thanks mate 👍

The Batteries are 15KWH 51.2V lithium ion batteries

So how many solar panels are needed to charge one batterie in this setup?

We're located in the Gambia 🇬🇲

Am in a country called Gambia 🇬🇲

I don't really know the answer to that because the home owner ordered the materials from china

No we are located in the Gambia

Not a mistake This is Ivem that means it can work without batteries External breakers are recommended by the manufacturer

Thanks mate

You can even use only the panels without batteries with these inverters. The Batteries are just there to store energy which is to be used later on.

Thanks am proud of you too✌️💯

Am from the Gambia 🇬🇲

Soldering was not needed but crimping was done behind the scenes

How

Thanks bro

Yes it should

And they made relatively safe distance from each other

No 1 inverter isn't enough, the building has a lot of loads and getting an higher inverter will require 96v

@Opsolar what on earth will he use more than 22 amp and continues 5kw in home residence

Thanks mate
