Since we are assuming here

I will first suggest that getting an inverter that can help you prioritize the charging current is very important.

For your battery bank, you need 80A max. To charge without stressing the cells

So that will require 5.5Kw - 4.6Kw of PC array to charge within 2-4 hours max. (Ideally)

For your loads you will require minimum of 12.6Kw based on efficiency list and all plus irradiance variations.

This being trashed.
With a programmable inverter. ...say Hybrid ..you can set max. Charge to battery and direct the rest to the loads.

And in low sun shine days .. your battery can help you out.

Stay safe and enjoy the weekend.

HI,
Good day Monopolistic,

i noticed you are having difficulties making decisions on your solar system to be powered due to financial constraints, the good news is that we have exclusive partnership with quite a numbers of international Renewable energy experts.
we will like to be part of your decision making, please kindly message us or call us 08088148034

monopolistic:
I get your point.you mention 12v 200ah battery and each alone cost 150k naira both cost 300k naira..you see why am confused.

Which of this inverter you think is better and will preserve battery life.

Can you kindly list all what i might need so i can buy them on jumia.
Thanks

Good day Cypha,
We are a renewable energy company and we will like to provide our services to you.

How can we be of help to you.

cypha:
Good day , please I would like to have an estimate of how much an installer will charge to add solar panels to an already existing inverter system, the inverter system comprises the following
3.5kva felicity inverter
2 FLA 220ah batteries

I have bought 4 280 watts mono panels, and a 60 amp mppt CC,
I am yet to buy the mount,cables and breakers because I Would prefer the installer buys or advices which to buy ,

In Ibadan Oyo state. south west region.
and Yes about the pollution, i cant help to notice the tainted clay they have all over their bodies, looks like its polluted with crude oil. my POV

lastclaire4:
Which region please? Do you know what pollution has done to their land? In some places you wont even find fish because the land has been polluted.

I was expecting bigger fish, I have caught something close enough to the biggest displayed here.

I can help you get it and waybill it to you, as we have distributor right with Amaron battery in Lagos.

Please i need a good 200Ah battery in Ibadan. i used Sukam battery since 2016. 4 years now. but it has gone weak. someone recommended the Amaron quanta battery. is it also good? if yes. i would need one for immediate purchase in Ibadan..... Thank you

Good day guys,

Please am in need of an installer in Ilorin for an energy audit at a golf club.

Please its very urgent.

Am out of town to get things done and clients needs immediate coordination.

Contact on signature.

How can i upload files above 4mb most of my pictures are of high quality and size

Still learning ... But this were some abstract pictures i took at an event earlier today.
No editing app.

Thanks Bro...

kadorzy:
Bros... Stay clear except you don't mind their sudden death usually in 6month or less.
I've used in 6 installations with various performance and feedbacks. In my opinion they're over priced El cheapo (in Niyi's words).

Lol I typed that with frustration ni, just too tired before

eleojo23:
...or forever remain silent?...

Please i need some honest review on "Britelite Batteries" anyone who has used or bought it for client or personal use, please do state so now.

Thank You Sent A Email Already

Runx:
Send your request to my email

Good Day Everyone,
Trust we all doing fine?
Please i want to know of the version of victron connect that can allow me relay info from fanpusun to my phone.
I was working on some diy project on my phone earlier but it was stolen so i need someone to please enlighten me.
So that i can get the info of harvest and all that without briking it due to victron update etc.

thanks

Hi Olopan,
Please, what software or app did you use to draw this....? Thanks

@simydan thumbs up to the well detailed explanation.
&
@princeCEE please do look out for this attached document.

Fill it up and send to me.

Good Day PrinceCEE
I'd Like To Commend You on taking this bold step, but i will suggest that you carefully look within those appliances you have listed and choose those you think are critical.
If you were to be estimated based on your request, am afraid the cost will make you scared. For me airconditioner is not a critical appliance and also the home theatre too those gadgets consume medium to high power.
You can as well take advantage of our companies free consultation as to determine your power needs.

PrinceCEE:
Hello!

Please I need candid advice on the best choice and also the the budget from the inverter to the installation cost.

I need a setup that'd last me for the whole day, given the power consumptions.

1. 4 laptops
2. One 32inch led tv
3. Three ceiling fans.
4. 5 energy saving bulbs
5. Home theatre
6. AC
7. Mid size refrigerator

I would want both the inverter and solar together. So what's gonna be the likely configuration and budget?

care to please give more info?

I was in a bank the other day to market these high-calibre ESS.
The guy in charge said that they already have back-up generator and each computer station has its own UPS.
As he was saying this, PHCN/NEPA took light.
The banking hall went dark, in mid day, while the sun was shining hot outside.
For a few minutes, everybody stood still, while the UPS stations stated screwing that annoying alarm sound.
Then a mighty roar as the back up generator started up. And died, A second roar as a bigger back-up for the first backup kicked into life.
Consuming litres of diesel, and belching thick toxic fumes into the surroundings.
Within a half-hour, PHCN/NEPA was back.

All the noisy beep, beep, beeeeeeeeeeeeeeeeeeeeeep, nuisance smells, poisonous fumes, embarrassment of stop-work, danger of inflammable fossil fuels in close proximity to confined premises, lost profits due to maintenance and repair costs of over-large generators, all that, could be better managed at lower costs, with a LiFePO4 ESS.
Get in touch for an energy audit.

okay!
with the 6mm cable, you will loss some power along that long stretch of length.

so here lies the Dilemma, 2s2p or 2s3p for the future is the best and most sweet spot you should opt for, but with the cable not being so large coupled with long distance.
BUT
because your cable is 6mm i will suggest a 3s2p so you will not loss much power.

One other thing i notice is that, you will most likely oversize your array by 15% or 115% which is great but with a down size of overcharging your 200Ah battery. .... you don't want your sweet battery to start releasing Hydrogen gas...... No.

if need be that you will really use the PV upgrade, then the 3s2p option will be best advice for reason stated above,
* As it will not allow the current to overshoot too quickly to overcharge your battery.

These are my own POV.

Topmost11:
4×150watts panels(two more to be added by feb ending) in parallel
25meters×6mm cable
12v 900vac inverter
60a mppt CC
200ah battery

Yes, but went to Lagos to get a few items for a site maintenance.

oliyeniun:
Thank you sir. Are u in Ilorin?

Hello Oliyeniun

I'd love to work on your system for you while you gain knowledge too.

I guess you have everything needed for the installation on ground?

I will get the electrical schematics to you later on in the day.

Yes the connection is different as you will have Eliminated some components and set up will come out different.
And I will recommend a minimum of 10mm or 6-8 AWG cable from PV to Inverter (since hybrid)

oliyeniun:
Hello house,

Please i am trying to install a solar panel system for my parents, can you recommend a good solar installer in Ilorin?

Secondly, I want to ask if anyone can help with the schematic drawing for hybrid inverter connection. I am not an expert but I try to read up, and from my readings, it seems that the connection of solar hybrid inverter is different from the normal solar-inverter connection.

Thirdly, I assume I don't need a charge controller if I am using a hybrid inverter...please help clarify.

Lastly, what is the recommended cable size and type for connection from the panels to the inverter....this is so that if I don't get a recommended installer, I can at least monitor the one I can manage to get to ensure a good connection.

Thanks house.

What's your operating voltage 24V or 48V?

If it's 24V 2s 2p ..then all good but if it's 2s 1p then you Sir, fried the AGM Tech.

Reason being that you over shot above the max. Capacity of current to be used to charge the battery.

In other simpler terms
Say I have 200Ah battery / 5 ... i.e 40A max. Charging capacity i.e. Et. Cetera.

Now with your setup you have 2200Wp of PV array @ bulk voltage of 28.8Vdc
2200/28.8 = 76.4A of charging current which most have resulted to the bloated attributes.

Hope have made this clear enough.

iykmon:
I need some clarification on why my batteries i have used for two years now are expanding and releasing Hydrogen gas.. i have two Solar charge controller to the batteries. Reason for the two charge controller was limitation to the rating on the charge controller. 40A and i had no fund to buy higher rating then.
Battery = 4 batteries
Charge controller= 40A each.
8 panels (4 {250w} and 4 {300w} )

Is the CC a PWM? Or MPPT
And where are you based at in the country?

Topmost11:
I'm thinking of 2s2p configuration for my panels from the present parallel setup. The CC is 12v/24v and battery 12v. Any comments/suggestions/comments?

This is one of the reasons I'm not too keen on roof work; if I had subscribed to roof work, it means I will look for ladder and maybe an expert o do this 'simple" task.

Good day folks,
We at Rendezvous Solar wishes everyone a splendid and peaceful year ahead.

That's why we thought to give back to the society by offering our consultation's services 101% FREE i.e. FoC.

To people with an inverter displaying or behaving erratically,

Battery that drains too fast and quick,

Or a solar panels that doesn't charge your battery effectively.

Call us on 08057732901

Thanks for the kind words.
Have a splendid night's rest.
And have solar

tonididdy:
You are so nice bro with your responses. If this is 90% then I do get 13.5v (as I type now, my gen is on and the CC displays 13.5v)

This is so sad, may God protect us this season o harmattan.
