A genuine 6.5KWh LiFePO4 battery is just under 3million. Never mind the 15KWh they write on the body of some batteries. This is not true.

One will need about a genuine 15KWh to have any descent power supply and we will be into the 6million range for batteries alone.

For me, this is where everything breaks down value for money wise. A 20M off grid solar set up for a residential home is not good value for money from my perspective.

Stop misleading people.. 3M will get you 14.4KWH real capacity now...

Lithium Price has fallen in china drastically.. making it affordable for home storage, China has mass produce them its soo affordable, just stay informed.

Below is a Lithium set up under 1.3M

Just assume the inverter is your generator set. Do you think 3.5 kva generator can power a pumping machine or electric iron conveniently.
You may need to increase the solar panel and inverter capacity to do so.
Your 1200 watt panels won't charge 4 batteries efficiently. It would still be at the same level of the 2 batteries or 3 batteries distributed in 4 batteries. I use similar set up as yours but 2080 watts panels. It's really the panels that supply the main power and the higher the capacity, the more the capacity of the inverter at the appropriate kva.

He couldn't Pump not because inverter could not handle it, But his Battery technology cannot.
I have a 3.5KW inverter and can Pump flawless with 24V 200AH lithium ion phosphate batteries, equivalent to his 2 tubular batteries, But has more energy Density and higher Current Deliver up to 1C..

Lithium batteries have changed the game in renewable energy.. a small 12V 200AH can power Iron because the batteries can deliver up to 1200w continuous without stress.

Also I have been using mine for 3 years plus with little degration.

Thank you for your response, but how many kwh will the lithium bat3 be?
i.e if am to buy 48v what kwh?

1000WH = 1.000KWH or 1KWH

So 5120WH in my response is equal to 5.12KWH or 5KWH for short.

abbeymighty:
Good day all,

please what is the Lithium battery equivalent to 48v tubular battery?

Tubular 48V 200AH 9600WH = LFP 51.2V 100AH 5120WH
@50 DOD for Tubular Useable capacity is 4800WH
@90 DOD for LFP useable capacity is 4608WH

So in terms of pricing, they are very close.
Tubular 48V 200AH is around 1.2M
LFP 51.2V 100AH (5.12KWH) is around 1.3M

So LFP pack of 5KWH 51.2V is equallent to 4 Tubular 12V 200ah batteries.

Dear All,

Got a quotation from another installer, just for comparison sake.
Is the second quotation not an overkill. I thought I'd be making some savings from a partial DIY then the second installer came with this?
Experts in the house, what do you think about this?

Accessories and mounting are not cheap, If you are in Lagos, I can help you lower the cost.

kindlyheart:
Is the multimeter still available

Yes, available.

Good morning all,my friend that went to china he sent picture of this battery,if he s should buy it

Buying for resale or personal use?

Nutridelfarms:
Thank you for your comments. You're right about the installer taking the warranty up in case anything happens but that doesn't justify unnecessary mark up in the price. Increase in the price, fair enough but let it be reasonable. Honestly, money is not easy to come by these days. It's hard to cough out this much and I'm sure you understand. I want to optimize where I can and where possible and feasible with sacrificing quality. I am open to a win-win option that works fine for myself and the installer but he doesn't want to bulge on the prices, hence, the need to procure the materials myself.

Alright, just as posted earlier today you can go for the setup below:
Almost Double the Panel Size for the same amount: 5KW Inverter, 5KWH Batteries and 3,330W Panels

LFP batteries at least 5KWH 48V for a start, 1.2M Marstek you already source.
Hybrid inverter SAKO/WELION 5KW 48V with MPPT at 500K max.
Solar Panels 6 units of Jinko 555watts, 960K
Accessories and installation about 440k
To make 3.1M total

Nutridelfarms:
Good day people, I intend to install a 5/6kva hybrid inverter. I have attached the quotation received from my installer. Just wanted to get remark about the adequacy and reasonableness of this quotation from knowledgeable folks and experts in the house. I welcome any advice, suggestions, comments.
Is it advisable to combine a particular brand of inverter (eg GOspower) with a totally different brand of lithium battery (MARSTEK)? While my installer quoted 1.7M for the battery, I did some research and found the contact of the main dealer of the battery in Nigeria. I could get it for 1.2M directly from their office in Ogba. However, the hybrid inverter of the same brand (MARSTEK) cost 1.2M and they're not willing to reduce the price. They advise buying their inverter and battery together but completely optional with a caveat though - that combining my battery with a different brand of the inverter voids my warranty (10 years), as they cannot vouch for the performance of the inverter I would use if it's not from them or one of brands they've tested. They sent me a list of other brands that their battery is compatible with, however, the prices are ridiculously high compared to theirs.

Is it worth taking the risk to go ahead with the quotation given to me by my installer? I don't just think I want to buy an inverter of over 1.2M. It's a lot mehn.

Your installer is on point, he is taking full responsibility for sourcing and warranty claims, that is not an easy task.. do it yourself to gain experience anyway!

Since you are a Semi DIY, Buy the inverter and batteries from them, but you are on your own you will have to liaise with Marstek if anything goes wrong.

And let the installer do his installation job if he is still willing to.

You can combine inverters and batteries of any brand with no issue, A batteries Manufacturer should not use that as an excuse to void the warranty, it is a bad sign. You should be fine if you maintain their recommended charge and Discharge profile.

they should have gone ahead to tell you that your load also may void your warranty

adewasco2k:
Please i need recommendation for a solar hydrid inverter (48v 5 to 8kva) for about 800K
1. Sako
2. Growatt
3. Welion
4. Deye (this might be above my budget except i know exactly why this is the best option then i can up the budget)
5. any recommended brand?

You have done your research already and want people to confuse you.
I have worked with all these brands, they provide AC to your load, 1 to 3 are practically the same thing, 4 is a semi-pro with added features you may or may not need.
The Summary is you will get what you paid for!

Just go with what fits your Budget and what your heart chooses!

Juror:
Please breakdown how you arrived at your installation and accessories, budget 150k to 200k

Boss, just pass and move on.

Drgreatone:
I always thought my nominal voltage was 120. Just confirmed its 240v.
What's the max watts u av seen go into ur battery at this output?

Are you using new panels now?
Norminal voltage of Inverter does not affect your charging rates.
Panel Orientation, charging voltage, and Panel efficiency does..

someone using 4 units of 550w panels got 2KW.. even when nominal says 240V

someone using 4 units of 410w panel 1.64KW panels got 1.47KW at 111V even when nominal says 240V

Drgreatone:
Why 20amps with PHCN? Wont that slowly charge it?

20A on 100AH batteries is the standard I do with Grid charging.

Smartwoods:
Please how can I set this 52A on hybrid in inverter and 21A on charging with grid?

From the setting, use CSO as the charging priority
set the maximum Utility charge current to 20A.
maximum Solar charge current 50A

Drgreatone:
Good evening house. So want to get a clarification. I use the sms hybrid 2kva12v inverter paired to 5 fake 300w panels (learnt my lessons here already).
The max panel input i get is around 550w and if no load on, only abt 200 to 300w going into the battery. Had a bad battery so thought that was the reason for the reduced solar charging but i just upgraded to a 12v lithium battery and its still the same thing. Yet when i power a heavy appliance like my baby's sterilizer, av gotten close to 750w from the panels.
My question is why don't i get that constantly as that would help my battery charge faster. The battery charges well with NEPA but with them bringing my meter soon, not sure i want to incur heavy bills. Thanks in advance

What is your Charging Voltage, Bulk, and Float needs to be 14.6V so you can see max power!
Also, set the max charging current to the Highest possible for solar, its 80A as I recall.

606thearena:
Good evening everyone, pls guys I want to get a 5kva inverter system , my installer is giving me 3 m quotation plus installation with 7.5kva feleicity inverter . He said I should just get the 7.5kva felicity inveryer since I plan to use my A.c 1.5 inverter later on . That I will not regret it .
This is what he is offering
8 panels of 250 watts panels
7.5 kva felicity inverter
2 tubular batteries 220amp luminous
SMS charge controller .60amp
Surge protector
And after sales service for me .
Pls solar gurus in the house .
What’s your advise , I feel like it is too expensive, pls advise me .
This is my load currently .
65inches smart tv lg
Star link internet
1000 watts dvd lg players
One reachable fan
And small ox fan
8kg side loader washing machine .inverter
One standing inverter fridge
3 energy bulbs.
My target is 20 to 24 hours system . I will be waiting for your advise keenly .

2 Tubular batteries to run 7.5KVA Inverter, how? or its a typo?
this set up cannot run well o, 8 units of 250w is only 2KW, that can produce 6 to 8kwh on a good day, that's might not power your load for 20 hours...

with 3.3M here is my recommendation, to power your load without AC.

LFP batteries at least 5KWH 48V for a start, 1.4M max.
Hybrid inverter 5KW 48V with MPPT at 500K max.
Solar Panels 6 units of 555watts, 960K
Accessories and installation about 440k

You can add more Batteries and panels in the future to accommodate AC.

Icolosis:
Good evening guys.

I need a battery and inverter to just power my laptop(macbook pro with 45watts charger) and phone, nothing more.
The power here is pretty decent just that I need backup power to be able to keep working on my laptop during Nepa downtime and on the days they move mad for example this recent strike.

what battery and inverter specifications would serve well for my needs.
Also can I go for a lead-acid deep cycle battery since I don't have much power needs.

Buy a 500w inverter sachets ones, since your continuous load is lower than 100w.
Get a charger, If the inverter does not have one, get lead acid since you are already thinking about it.

My Standard recommendations are:
12V 1KVA Hybrid Inverter with Inbuilt MPPT 40A.
12v 100ah LFP Batteries, cables to connect and you are fine.

Here are some details about the product.

This thing is for powering to that stuff listed.
50w panels can only do 150 to 200 wh daily, is that enough for your needs? if not, buying the solar 300w generator advertised on previous pages is better.
