Thanks.

Is there anyone with recent biometrics experience at Ogun State command-CID or I should just go to Alagnon straight?

Say you want to build a smallish system and your household can get by on like 500w of day time loads and 300w ish of night loads - you may have to run the 1.5hp pump off grid or gen primarily.

If you go the lead acid route, every 12v 200Ah battery can support about 120w of loads (the C20 rating) so you would need 4pcs of 12v 200Ah to run your 300w of night loads from 6pm to 8am every day - 4 pcs of 12v 200Ah also fits your existing 48v Luminous inverter perfectly.

The solar panel wattage needed to support 500w of loads from 8am to 6pm and 300w of loads from 6pm to 8am will be any where from 3000w to 4000w of solar panels - at this point in tech and time, I would say choose the larger panel sizes so at least 450w - 9 pieces of quality 450w panels will get you to 4000w mark nicely and put you on the energy independence side of the curve. 6 pieces of quality 450w panels will give you enough energy most days.

All these above assume you are fully offgrid, if you get some hours of PHCN or Gen then you can size your panels leaner, if you are able to reduce your loads too then all the better.

You will see that the bill of materials for this 'small' offgrid system runs into a few millions at today's prices. If budget constrained, the more you can prune down your loads, the more you can make your system lean.

The idea is that this will be your system for 2 to 3 years and then you can upgrade to better tech - the panels and your inverter can likely be retained through all your upgrades but you will most likely need new batteries.

If your budget supports it, you can get 51.2v 135Ah LFP battery pack instead of 48v 200Ah lead acid pack (4pcs of 12v 200Ah lead acid) - with Lithium you just need to get your charge profile right and set a suitable LVD and you can worry less about whether you are overloading the batteries or whether there was enough solar charge for that day. With Lithium also, you can expect from 6 years and above of use vs say 18 months - 4 years with lead acid. The level of positive assurance is higher with Lithium i.e a well designed pack with decent cells will likely give you 8 years or more of service. If you cross 1 year with your lead acid, you will celebrate, 2 years you got something good and 3 years and above you got it right.

If your budget does not cover enough for 9pcs of 450w panels + 4pcs of 12v lead acid batteries at least then you are going very lean, if you already made the decision to go solar any ways then I would say just get 4pcs of 450w panels + 2pcs of 12v 200Ah + compatible inverter (you will need to jettison the 48v Luminous) and use this system to learn what is possible - later with your learnings and more cash available and faith in renewable energy you can build a system more in line with your needs.

One viable way to proceed as a newbie is to get a quote from an installer and bring it here for people to help you critique the materials used and costs. If you are more DIY inclined you can purchase an energy meter within 10k and use it to determine what your appliances consume - this will put you in a very good place with respect to sizing your system properly.

NiyiOmoIyunade:
I would say do not be discouraged by any negative feedback on your quest for knowledge and to build a system.

If all you need is electricity to run your pump once in a while a suitable sized Gen may be your cheapest bet.

If you are looking to solar to solve your day to day energy needs plus run your pump then it is doable but you need some knowledge and a plan.

Yes the LFP chemistry is probably the best deal out there today but you can get by on basic lead acid for starters.

So work out your energy needs first and come back to the house for suggestions - if the only equipment you have is the 3.5kVa Luminous then all good as it gives you some leeway to to get better equipment around it.

I second the idea that if you have solar + 24v 200Ah of lead acid, you should be able to pump water during sunlight hours, your solar panels would do most of the heavy lifting and not stress your battery unduly - you will need to match battery nominal voltage to inverter of course.

So come back with your final goals for power and the good people here will certainly give you ideas, product suggestions and designs.

@cedarfarms
You need basic understanding when is comes to sth of this nature. Now, you mentioned 2 batteries for 48v which shows u still need to learn a lot. Truth is you will get enough information online.

samnaija:
If your inverter currently, is 48v, you will need 4 batteries. Increase your panels to 300 watts 8 pieces.
The truth about renewable energy ,use the resources when there is sun.
Your pumping machine comes on during miday , you are ok.
Or do you currently have batteries?.

earthrealm:
for battery, if solar is your primary charging source, you can consider getting a minimum a 7kwh to 10kwh lithium bank. trying it with 4 units flooded battery and an oversized solar panel array eg 8units x 300w is a bit risky, as the sun cud go down while your panels are carrying the load...and this will result in the load being transferred to the poor flooded battery, who are not designed to carry such load.

lithium is the best for loads like this, the only challenge is that the luminous inverter charging algorithm isnt suitable for lithium cells, so you need to dance tru hoops if grid is your primary charging source, but if its solar, you would be ok

lastly, its a 50/50 hit if the luminous would be able to power the sumo, check the surge rating of the inverter..if its upto 6000watts, then it should,

samnaija:
My brother get a very good, 3kva inverter the luminous might work. Even with 2 tubular batteries you are good to go. The only thing get enough panels. No be to pump water. So far you have a enough panels you are okay.
300 watts panels 6 is ok.
Dont let anyone deceive you , tubular is okay, for what you want use it for.

I use my tubular for my pumping machine and water heater and air conditioner and no problem.

Lithium is of high chemistry, but of course more expensive .

NiyiOmoIyunade:
I am not sure that a Luminous 3.5kva would start up a 1.5hp pump successfully - it is not that 3.5kva is not large enough but rather that the Indian inverters (Sukam, Luminous etc) generally have poor surge handling ability. They tend to go into overload when a large inductive load tries to start up.

But do test it and see how things go and then can begin to move from there.

Any fish farming thread like this?
Pls share link.

prophetfire:
Which message. He is a hypocrite. Do you know the fetish practice and idols he paid homage to before his coronation? Even the ones they carried him across the sea in a canoe to go and venerate and sacrifice? Christians of our day, you guys are so gullible and lack discernment. Anyone that shouts Jesus is Lord is acceptable to you. He is deceiving people.

Kill that idea of the Sentra and take the civic instead.
That’s the top choice for me amongst the 3

Lol...That installer does not know anything. Look for a professional electrician to do a 3-phase looped into a single phase for your cutout fuse. That way, once your neighbours have light and you don't, simply remove the cutout and fix it any of the other two cutout phases that have light!
