Note all lead acid batteries must bow to the C/10 rule, though some premium models claim C/20.

What this means in simple terms is that you shudnt charge or discharge at above 10% of battery capacity.so your 150ah bank .this is 15amps max, you could have even get away with C/15 to C/20 if its not done too often.

Charging leadacid battery above their specification causes them to heat up and the
internal lead plates buckle & deteriorate.

4 x 300 watts is ok, as due to inefficiencies and other reasons..you would likely be getting about 600watts to 900 watts on the average. You may set your cc to cap current @ 40amps..if it has that functionality....
The slight drawback would be some energy might be wasting on super sunny days when you are running heavy loads and your panel may want to push 50amps to the for the load and battery charging to share...

You dont need an external charger, your inverter charging shud be adequate.

What you need more is a means to manually send 15.5volts or 31v since urs is 24v bank to the battery pack every month for 4 to 6hrs for a process called equalization&desulphation.....what this does in essence is to boil the flooded battery so the electrolyte mixes thoroughly and deposites on the lead plates inside the battery are dissollved/knocked off.

Note: only flooded battery need this periodic boiling

Q1: Since I will be using (2) * 150ah, on C10 tubular capacity at 24v setup, which of the below example LOAD should I follow per hour?

Formular used:
Battery Amp / C Rating * No of Battery * Volt

Example 1:
150ah / 10c * 2batteries * 12v = 360W

Example 2:
150ah / 10c * 2batteries * 24v = 720W

Please which of the load per hour should I use at Max?



Q2: Luminous Optimus 1600VA/24V has max (18amp), will this be sufficient to charge (2) * 150ah @ 50% DOD?

Oshomo12:
Take very good note of this, abeg, buy good solar panels o. or else all those writeups will turn to stories!

Like which products is good?

My brother I am very grateful for these explanations.

Can this -> PowMr 60a MPPT Solar Charge Controller do the equalization&desulphation by sending in 31v ?

Since it's 24v setup, by 15amps do you mean 15amp * 24v = 360W. So I shouldn't use more than 360W per hour?

Please enlighten me more.

Thanks bro, words are not enough to for this deep explanation.

[quote author=NiyiOmoIyunade post=115473623]Why do you think 1,200watts of panels are too much for your 2units 12v 150Ah batteries?

Now I am enlightened that 300W is good for my setup, I will certainly go for it rather than 250W.


If you get very good panels and decent MPPT CC, your 4x300w panels can generate up to 4,800Wh on a good day, your 2x12vx150Ah batteries can store about 3,600Wh of energy of which you can expect to drain like 2,000Wh daily at about 50% DoD

Please recommend moderately price 60amp MPPT CC that can carry my setup without issue. Also, since it's 24v setup I was calculating 2*24*150 = 7200Wh (50% DOD = 3600), please correct me if I a wrong.


Above leaves you about 2,500Wh of free solar energy to use to run day time loads - your fridge alone can easily consume over 1,000Wh between 8am and 6pm - you can easily answer this question by attaching a watt meter (people here sell them) to the fridge for a week.

I bought this -> Binatone AC Cool Guard Voltage Protector-ACG 1500 to get Starting Watts (650 - 750) & Running Watts (165 - 220), do I still need the watt meter?


With your flooded batteries, you do not really need a desulphator - a good equalization charge every 30 days should put you in a good place.

Can this -> PowMr 60a MPPT Solar Charge Controller do the equalization?

earthrealm:
THEN 4 units of 200ah 12 volts mecuryflooded battery. 8units 250 watts solar panel, 60amps ep solar mppt cc,
though this has no bearing on if the inverter would carry the fridge or not

Thanks for the enlightenment, this is the best info I have gotten regarding my intended setup.

I was thinking (4) * 300 Watts Panel will be too much on (2) * 150ah Luminous Tubular or should I go with (4) * 250 Watts Panel?

Secondly what about I get battery charger so I can charge it faster on raining days with NEPA or Generator, if yes how many Amps battery charger should I go for?

Lastly do I need battery desulphator?

earthrealm:
It should, though no call police for me if it doesnt ,

My 1.5kva 24v luminous powers a 350Liter double door haierthermocool fridge. 125w running watts...then was kazeem3d , turned to 190 running watts. Inverter still carried it ok

Thanks bro, I won't call police for you

What's the Battery Amp & Panel config did you use for it?

dollarnaira:
It depends on the make of the inverter.
If it is a true 1600A psw, then half of it should power it. What make is your inverter?

I am yet to purchase it.

But this is what I intend to buy Luminous Optimus 1600VA/24V

saint2ace:
Yes, it can....

Thanks

teemac01:
i believe someone asked a very important question here but every other person is just after selling their nonsense...i was made to understand that you can share you inverter experience here no sell junks here...can we get a reasonable answer to this please thank you

The bolded got my attention.

I asked reasonable questions on the main solar thread Solar Energy, A Complement To FTA, but my major questions was ignored after many pages, reasons I believe was because I didn't contact those who posted advert for me to call.

It took me one week to read from page 1 of this thread to last page, and saw where users refer others to main solar thread to get their questions answered but only fee answered some of my questions, and I stopped asking when the questions are deliberately ignored.

They forget even if you don't call them you can equally refer others to them.

Buhari is not the majoy problem of Nigeria, but Nigerians are problem to Nigeria!

TechGeek777:
Thanks a million for your direct answers I greatly appreciate it.

I still have some questions itemized below:

1. Will 60A charge controller be suitable with this system that can charge Tubular battery?

2. Which budget (50k - Max 80k) quality MPPT CC would you recommend & Amp?

3. Do I still need battery charger since am using MPPT, if yes how many Amp?

4. With the above devices, do I still need Battery Desulphator/Desulfator Rejuvenator?

5. Which budget (50k - Max 80k) quality 300W 24v Panel would you recommend?

NB: Please I know the questions are much, but it's good I know what am going into to avoid regret!

@earthrealm please am still waiting for these, others can also contribute to it

Jefferyzz:
Techfine mppt

Please drop link for this.

How effective is PowMr 60a MPPT cc?

mctfopt:
Where can you get PowMr MPPT for 50k? Drop link. Thanks

URL: https://www./powmr-60a-mppt-solar-charge-controller-12243648v-92563941.html

It's actually 56k plus some fraction if you add shipping fee as the fraction is based on your location.

Jefferyzz:
If u're looking for 60a mppt cc. I'll recommend this type. I got it 85k last week. It readings are accurate with figure on my BMS. If u're looking at Budget 60a for 50k. u can go for powmr cc. But the max u'll get from it is 50a. Powmr cc is on jumia, konga n AliExpress.

What's the name of the CC you bought?

Jefferyzz:
Breakers are circuit breakers. SPDs mean surger protective devices. SPDs work with breakers.. which means u connect it very close to ur breakers. Or better still just get fast acting fuse with appropriate rating. U'll just b ready to buy multiple fuse Incase dey blow out

Thanks, this is clear now

earthrealm:
Me too, am looking for....if you see , come and tell me too ...

Though any serious inverter would have it. Magnum and victron inverters, but they cost an arm and a leg, far above the purchasing power of the average 1.5kva inverter user

Thanks for your input, I think I will have to stick with Luminous inverter.

1. Can I attach solar panel to non hybrid Inverter e.g. Luminous Optimus or Luminous Eco Volt ?

2. Assuming I need 900Watts panel to charge (150Ah * 2), what combination of Mono panel will be better; is it (225W * 4) or (300W * 3)?

3. Since it will be 24v system, can I use panels of 12v, or must it be 24v panels each?

Please answer accordingly, other input are also welcome

zeestone99:
You will have to buy Ac and DC SPD's

I sell them you can call/chat - 08117398294 to order

Is it the same thing as DC Breaker?

olopan:
Vmpower has editable options but I will find through the manual and revert back to you soon

It is an hybrid
30A PWM controller and also transformerless

Okay, is transformerless better than transformer inverter?

Penuelseun:
Tbb has voltage editable features, but you will have to go to their office for that, or buy the external console to do that

It's noted, thanks

zeestone99:
1 - yes. I assume the 5000w is powering the whole house.

2 - no. The tv guides are basically a kind of avr. Since you don't have solar. You can buy ac SPD

1. Yes it's powering the whole house.

2. I intend using solar, hence am asking these questions. Which SPD should I buy?

earthrealm:
most luminous inverter are designed by luminous intheir wisdom..to output max 14.4 volts and dont hv desulphation setting. flooded batteries are happiest charging at 14.8 v olts and desulphating at 15.5 volts for 4hrs every few months.
those inverters you listed there dont have those capabilities............

it will work o....but the battery will not be very happy...and may likely dont serve at its optimum rating

with editable battery voltage charge setting...you can set the charge voltage to what u want and also use it to desulphate even if your inverter doesnt hv a dedicated desulphation button...

other than that, luminous is a strong inverter, hv used the luminoius ion in a setup for over 10yrs, only issue was stuff cooling fanfrom dust...which was replaced. however that design flaw isnt serious if using normal smf battery,,apart from quanta/flooded battery....quanta likes to be charged at 13,8 volts

Thanks for the enlightenment, which 1.5kva inverters have the feature bolded?

earthrealm:
Best you go for an inv erter with editable charge voltage settings,
Luminous doesnt have that setting, so a deal breaker for me.

If its normal sealed leadacid you intend to use..you cud be fine, but if its flooded battery...then its important you get an inverter with the functionality i explained above

What is the advantage of inverter with editable charge voltage settings?

I intend to use it with two "LUMINOUS NRGT TUBULAR BATTERY 150AH/12V" because of 24v requirement

Please explain better

mctfopt:
They'll all good. I have a Luminous 1.5kva 24v iON model that been in operation since 2017. It's almost working 24/7 and no issue till date. So go for any model, you are good.

Edit:

Okay thanks, but which among the three models listed can I use Generator, Nepa & Solar Panels to charge?

Still waiting for response to this

zeestone99:
Just install protective devices. Avr's and spd's

1. By Avr's, do you mean stabilizer?

Because the main source from NEPA is connected to 5000VA Century stabilizer I bought last year.

2. By spd's do you mean Surge Protecting Device?

All outlet except electric stove are connected with D-Marc TV Guide

Please answer yes or no according to the two questions above

@earthrealm,
@ZeeStone99,
@olopan,
@mctfopt,
@Kiekie1,
Others


Please which of these inverters should I go for, considering I want to be able to charge the battery with NEPA, Gen & Solar?

Luminous 1.5KVA/24v Solar Hybrid Inverter
ECOVOLT 1500VA/24V
Luminous Optimus 1600VA/24V

Note: I need the one that will stand the test of time.

olopan:
Go for simba, their service center can cover you under period of warranty plus even after warranty. Not saying others won't just ensuring you get the good side of the deal.

Thanks I appreciate this

Please lets move on sir . Zee lets move on ooooo ,

Seconded

I have followed the thread from page 1197 after reading the first two pages.

Please guys let's keep it cool with each other as this WON'T help other newbies solar enthusiastic like me.

Exumal:
1. It has an inscription yaofeng as well as cst
2. They don't shade it like others, thus it's in carton well sealed.
3. It's heavier than others with the same size
4. When you look at the stainless plate covering the coil below you will notice it's a bit longer.
5. It's comes with the model No: SV6800. The SV6800e is the electric starter type with rollable wheels.
6. The price is 145k. I've tried asking all over Ibadan, though never went to Ogunpa. The best price is #145k, some will even want to sell higher than that. Even at Ijebu Ode, it's #150k

This is informative thanks. Do you mind sharing pictures of yours capturing the inscriptions?
