I am willing to remove the AC and also willing to spend 1m max on this. And I will still be on the national grid.

MontyNG:


Well, Hyundai Kona (Full Electric, 250mile range) is currently being assembled in Nigeria. Why not just go all the way

That's my wish list for next year... This year, it's to add another 30kwh lifepo4 batteries to take me completely offgrid

smallsmall:


I prefer a Hybrid Car (Fuel and Electric) than a full Electric.
Charging a Full Electric in this Nigeria where Power is epileptic and there are no charging points in most places, could mean one gets stuck on an Express Road without a charging Point in sight.

As a new convert to the LifeP04 battery geng, i have been doing a lot of research on the different brands and capacities available. Of course, using LifeP04 also means you have to learn about the BMS (Battery Management System) and how it is included in your entire inverter system. Now one of the initial drawbacks of the move to LifeP04 was its high cost and availability. Buying from big name brands will seriously dent your wallet and a lot of people preferred the DIY approach by busing cells directly from China and attaching a BMS to the installation. This greatly reduced costs but now added complexity of installation and needed some technical knowledge. While most users will have preferred the first option many were driven to the latter due to costs and therefore led to a surge in demand for battery cells and installers. There are some new products out now that appears to have a middle ground option.

Server Rack LifeP04 batteries

Now, most LifeP04 cells bought from China from Manufacturers like EVE, CATL, LISHEN are 3.2V. So, if you need to build a 12V, 24V or 48V battery bank, you will need to buy multiples of these cells to build a bank. You will also need to buy a BMS and other necessary accessories to build the battery bank. This entails a lot of research and technical expertise for which many may not have the time nor energy for. With these pre-built LifeP04 Server Racks, its just plug and play. Though right now they are limited to 48V 100ah capacities, i think for the ease of mind and integration they offer at their price points its a good deal. What do you all think ?

MontyNG:


The battery model number is UU 24-200 and yes, it's in an 8s configuration

Other info I've found:

Rated Voltage: 25.6v (what's this?)
Charging voltage: 29.2 - 30v
Cut off: 2.5v per cell ( Does that mean the BMS cutoff is 20v? Can I then set my inverter to cut off at 21v

Dishtech:

25.6v means 3.2v per cell (normal voltage) 3.65v maximum voltage.
2.5v is the bms cutoff voltage.
Charging voltage should be 29.2volt
If you set your inverter cutoff at 21v it mean it mean you Have 89% DOD. i.e 11% remaining to be empty.
If you're inverter has editable DOD I will advise you leave 20% or 30%. i.e 21.84v or 22.76v.
If your inverter is not editable then it needs some circuit for that. or check your inverter cutoff voltage. Some 24v inverter cutoff at 21volt while some cutoff at 22v.
Cutoff mine at 24v.

MontyNG:


Thanks. I can set my LVD on my inverter and I've now set it at 24v. Which I now believe to be about 25% remaining. I try to run the battery between 90% and 20%. But the inverter starts beeping at 26v which is a bit annoying.

alstacs:


I've been asking how these parameters apply to tubular batteries. Or better put, what are the parameters for tubular batteries?
Thank you

Penuelseun:
Most tubular batteries recommend a charge voltage of between 14.8v and 15.0v, 29.6v and 30.0v for 24v systems and 16.0v to 17.0v[32v - 34v] equalization voltage once in 2 or 3 months depending on usage

Hello all, I found this page through google search, I have a question.

I have a 1kva inverter system and 4 pieces of 150ah ritar batteries.

It’s serving me well, loads I use on it are, my tv, two ceiling fans, laptop, bulbs, dstv, and sound system. It last me up to 18hrs of continuous usage if I don’t charge. My question is, due to the epileptic nature of power in my area, I would love to go full solar and not depend on PHCN to charge again. I was informed by a friend to get 4 solar panels (200w), I have no idea on anything about solar, what would I need and what budget am I looking at for the solar setup? Thanks everyone.

ahamlee:

What are the DOD of a tubular batteries please?

Timekeeper452:
please can someone explain and guide me further on this?

Penuelseun:
is your setup 12v or 24v? You need about 300w × 4 panels with an mppt controller for a start, more panels if you plan on using the batteries while charging. Also depends on if you will be charging it simultaneously with mains power during the day.

mctfopt:


I think you should buy lifepo4 cells and BMS and run it yourself. It's not that hard. You'd get a better bang for your buck that way. DIY all the way

GeorgeD1:


we live in quite interesting times indeed. this is what some of us predicted some time ago with lithium technology.
finally it's beginning to go mainstream. soon, we will have more oems coming out with these sort of plug and play
models that require nothing but rudimentary knowledge of positive and negative battery connections and by
then lithium would be a household name.
i think it's the way to go provided price point is reasonable and quality of cells can be guaranteed.

Oga valto na me dey chat you for WhatsApp, pertaining the inverter ,abeg sell for me ooo

Oga valto thank you for the deal,I received it this morning

samir101ng:


And risk a kazeem solar installer or the time and energy needed to put together and monitor such a system abi ?

Bro, it's too much work & time for "me". And there are plenty mainstream consumers like me in the market that prefer an alternative to DIY.

Timekeeper452:
it’s 24v, I plan on using it while also charging, if power comes, I plan to charge with power too, if it doesn’t come I don’t mind too. I just want something that will make me be completely independent from national grid for days they decide to become fully stupid and take power for up to a week straight.

Penuelseun:
ok, you can go for 6 350w panels[or go for higher wattage if you have the funds] connected in a 3s2p configuration, with a 50a mppt charge controller

Cost & setup was a major barrier for new entrants tempted to switch over from AGM & Tubular Lead Acid batteries to LifeP04. LifeP0 need a BMS, compression (depends on user), different charging profile, etc. Generally, it needed more attention than the regular AGM or Tubular. With a server rack battery, you have an all in one unit ready to go. It comes with a BMS in built, capacitors and wiring harness for the batteries, bus bars, etc. To put things into context, check out this video for the installation of a 16s LifeP0 280ah EVE battery install https://youtu.be/iUuRRhLegrY. Fam, all this na work nah. Why do all that if i can get the SOK Server Rack Battery and install it good to go. Another context to look at is the price too. The SOK 48v 100ah Server Rack Battery is currently on pre-order for $1,739.99. A battle born 48v battery equivalent will cost you $3,196 at $799 per 12v 100ah a piece. That's a huge cost savings and makes it more attractive to buyers. The SOK also comes with a 10year warranty and its serviceable by the user which means you can replace any faulty cell yourself. .

Timekeeper452:
thank you so much for the detailed reply, please forgive my noob questions , I have no idea what 3s2p means , like how much budget am I looking at here?
How much is the 50a mppt charge controller , and can I go with any solar panel at all as long as it’s 350w?
