If you haven't done your installation, i will strongly suggest going for only 9 panel for those to be used in series.

If case 10 is to be used, say 5 panels in series and then have them parallel; these arrangements could likely damage the inbuilt MPPT if the Isc is more than that of the inverter's MPPT.

The best you should do is watch out! BTW, if you need a quote and installation with every bell and whistle that's going to keep your investment safe, be sure to reach out to me via contact in bio.

You’re 100% correct! Thanks for the advice. I used 8 out of 10 590w panels and intend to use the 2 in the village.

People with Ferrari are not many

Where do you place SRNE and Deye then? They are almost the same price with Victron

Ferdiwar:
This is something that comes up once in a seriously long while, so don't expect a fast response.

You can check online platforms like jiji for a used listing or a local shop within you location for a possible buy.

No wahala. Thanks for the feedback

Please, I've noticed something about battery prices in the abroad vs Nigeria.
Abroad the price of Gel and Tubular is about half that of lithium, but in Nigeria, it's almost the same price. In fact, there seem to be no advantages of buying lead acid in Nigeria. Can anyone explain this discrepancy?
Daalu in advance

Thank you so much boss. My budget is 1.5m

CuteMaro:
You can start with stating your budget. I am sure with that people can advise you properly. Goodluck!

Thank you boss. I chose tubular battery because of my budget.

Techsinnovative:
First mistake is the @ bolded. Forget Tubular/lead acid batteries. Think in terms of Lithium batteries. They provide way more storage density at the same cost, and will also outlast both Tubular & lead acid batteries

It used it be like that here too until lithium batteries with harvested cells (Grade B) started flooding the market.

Lithium batteries with grade A are still dang expensive, albeit a little more affordable now.

Grade B batteries will serve you almost as good as Grade A, since it's for home energy storage. They don't need to deliver humongous current as they did with heavy machineries in companies where they were previously used, resulting in better internal resistance as the grade b cells are only handling current for light appliances such as TVs, fans, etc,

Ok, the experts will give you more insight, but going with Tubular batteries is a no no.

You should get a hybrid inverter, no need for Charge controller. I will recommend Haisic 24v 4.2kva, got mine for 340k. Most 3.5kva hybrids comes at similar price range. Haisic is super quiet and can take up to 5kw power from panels.

As for batteries. To get a cheaper deal you should contact Mrreed or Valto for at least a 24v 5kwh hour battery. Or you can go for Haisic 24v 8kwh at 800k.

I'll leave the rest for the experts in the end you may have to step up ur budget by a little bit to get the best bang for your bucks. Good luck!

ask4bk:
What wire size did u use from battery to inverter?
Since you using 24v system it'll be cool you use 2awg size coz of high amps if you one day use a high inductive device on your system like pump or AC or iron. You could draw 80-120a. But if you don't use any of these then 16-25mm 3-4awg that you seem to be using could go.

Good observation Chief. The wire in use is a 16mm. The highest I have pulled is about 45amps from using a 1.5hp A.C, my pumping machine is 0.5hp. I set my charging speed to 40amps max.

I don't plan to use my AC with this set up anyways. Just for lights, Tv and Freezer and other light loads.

Are Deye lithium batteries Grade A?

Updated Haisic 8kwh.

okay thank you. your opinion is acknowledged

Yes they are grade A cells.

Tubular batteries are not in any way cheaper. They are way more expensive once you understand what you are looking at.

Your battery is basically an energy storage device, you store energy in them via charging, you use the stored energy in them via discharges. A battery has 2 major metrics you want to watch out for:

Storage Capacity Wh - multiply the ampereHour (AH) rating by the battery Voltage (V)

Usable energy available - recommended Depth of Discharge (DOD), the level the manufacturer recommends you can safely discharge the battery to before compromising its lifespan and ending up with a brick

Now lets take a general look at the figures:

2 tubular batteries 12v 220AH
Average (Cost of medium grade) - #600,000
Storage capacity(i doubt its real ) - 24v x 220 = 5280Wh
Recommended DOD to get 4 - 5 years lifespan is 50%, hence actuall useable energy really = 50% x 5280 = 2640Wh!!!
Longetivity - 5 years

4Kw Lithium battery
Average cost - #600,000
Storage capacity - 4000Wh
Recommended DOD to get 6000 cycles (>15 years lifespan ) is 80- 90%, hence actuall useable energy really = 90% x 4000 = 3600Wh!!!
Longetivity - =>15 years


i hope this helps clarify a bit. Cheers!

In fact the 4kwh is around 500k or less. But cells only is less than 400k.

Oh wow! thank you so much for this eye opener. God bless you.

I would appreciate your professional guidance on the best components and whether my budget is realistic for this setup.

My Budget and Requirements

Budget: ₦1.5 million

Power Requirements for my store:

10 lighting points
1 × 24-inch TV
2 × standing fans
1 × 1.5HP inverter AC (for afternoon use during peak sun hours while fans are off)

I'm considering a 3.5kVA 24V hybrid inverter to handle my load, especially the AC during sunny afternoons. However, I'm unsure if my budget can accommodate all my needs.

I need advice on:

Hybrid Inverter: What brand and specifications would you recommend?
Battery System: Which lithium battery brand and capacity should I choose?
Solar Panels: What type and wattage would be most suitable?
Charge Controller: What specifications should I look for?

My main concern: Can my ₦1.5 million budget cover a complete system that meets these requirements?

@ Dam5reey1 and other Gurus in the house, please i seek advice.

i need to replace my quanta batteries on a 4kw/24v hybrid inverter, am looking of getting a Lithium battery pack. However i have a strained budget of #600k. i need a minimum of 3.5kwh, would have wished for a 5kwh. I also need wifi capability for the battery as i plan on integrating it to Home Assistant.

- Can you please suggest what i can get in this budget range?
- Would i be able to achieve 5kwh if i assemble it myself (am comfortable with electronics), even if i have to add a little bit more to achieve?

Thank you for the tremendous knowledge you share

Can u tell me any 4kw lithium battery going for 600k . I mean solid heavy duty lithium battery 24v 200ah. Someone of u just type here without backing up what they say with prove

Shey b na 4kwh?
Weda 1v or 100v so far it is 4kwh abi?
E dey!!! Instead of you to ask politely to furnish you with such info, you had rather typed the above. There are different types of users here. Enjoy your day.

Are you "mavor"?

I have never insulted anyone here neither did i use derogatory remarks for anyone, so i wont take such from anybody simply because i pointed out the marketing was getting more than the advice i sought.

No one is feeding anyone here, and if some people don't answer questions, definitely someone else will respond.

To the few people that answered my questions, thank you very much, but for others trying to play mini god, omo i ready o and always strapped, but not on NL here, please simply inbox me so i can drop my details so we meet physically and do this, and not hiding behind the keypad on NL and type shii and bs to anyone because you feel its a faceless forum. I am done.

Happy Sunday Bosses

Please I want to ask. The normal house earthing rod and the lightning arrestor rod MUST they be connected together inside the ground? Or just leave it separately at distance apart. Abeg I need PRACTICAL APPLICABLE way that has been proven and working so far. Thanks everyone

I think folks need to remember the purpose of this thread, namely:

collective community information & Knowledge shared

We all need to remember nobody is being paid to share knowledge, information or technical skills/experience. This wonderful thread thrives on the sincere desire of good people willing to share in the hope of assisting others overcome this challenging Nigerian perplexity of erratic power supply.

i have benefited a lot by just reading the thread silently, only recently seeking advice. The response i got was clear and very helpful, with a member even linking me up with a direct line for Haisic batteries when i couldnt find it online!

Rather than allow this great thread to be derailed or gather negative energy; i choose to use the block button

i would suggest you tally up your power consumption first (check the label on each appliances for the power rating in watts, if not present in watts just multiply the voltage by the current shown). This gives you a good idea of your power requirements. If that your AC unit is not a recent modern one you may want to consider a 5kva inverter rather than 3.5kva

The gentleman in the post quoted below gave good summation already. Although i think Mr reeds battery should be under 600k

Good evening house

Please I observe my 12v 4kwh Haisic battery charges rather fast from 11v to about 13.5 but takes ages to charge up to 14.6v. This happens both with solar charging and grid charge
