I don't want people seeing it as a way of extortion, Dem go think say I dey use Dem chop,
I no be dat kin person,
Back in 2018, or 2019 due to my honesty saint2ace bought a brand new 100ah battery cha cha tear rubber carton and drove all the way to deliver few blocks away from where I live then,
The Chinese lady even mentioned it and I told her my mind cos I know Nigerians

Be like you no like affiliate money. 😂

It's not bad to get a commission from recommending a good product, or that your affiliates get a good deal because of you.

Just put caveats in your reviews and keep being honest.

ceejay80s:
.

Which BMS is this? I like this blue font and the arrangement.

Penuelseun:
use this 12v 20a charger to charge the cells to 3.65v each, it works surprisingly well

The cells will be in series or parallel?

richy02:
Guys please I reside around ijaiye and I want someone experienced to help out with a solar system installation, I need something that would carry my tv, two standing fans and maybe 6 bulbs, our power supply has been really poor lately, I would also love to know the estimated cost of the system

Have you gotten a solution now? If not let's talk in my dm.

justified007:
Really, I don't know much about lithium batteries o.

Budget is around 1.5m

1.5kw 12v hybrid -250k
3.6kwh 12v lithium-500k
530w Jinko biracials *4pcs-400k
Cable and installation Accesories-~200k
Labour and logistics -?

Your 1.5m should be able to deliver this system.

Valto:
530k with JK 200A smart active balancer bms

480k with JBD bms

Nice. What's the cell nominal capacity?

FEGEITOK:
I am in the market for a 10kVA inverter.

I am thinking about SRNE but what other brands would the house recommend that I consider?

I have a victron 10kva for sell o.

I dont know why people underate that device. The thing dey deliver for my end finish. Presently, that is the only thing powering my battery (presently using our favourite 24v 3000w sachet inverter, as my hybrid is decomissioned for now). 2 Jinko 590w panels in series (SW facing), on a 25.6v battery, and all my loads are used as i suppose to including all my family COOKING needs (all thanks to induction cooking).

I like the CC finish... Your slogan here legit... Na sense dem dey use for solar matter...

I've been using mine for God knows how long. If not for the advantage of high PV voltage of hybrid inverters, this would have been my best budget CC, recommended.

Although some cons about it are:
1. Can't set max charging current so it usually overheats when amps approach 40 and beyond
2. The cooling fan can't handle heat dissipation well at high watts values. External cooling helps plus the over temp protection works.
3. Cable connectors are too small for the max rated load, this also affects max cable gauge you can use.
4. Voltage, current and watts calibration is usually off by a significant margin. Newer models with updated software has a zero calibration feature for the voltage which helps a lot.

See a pair I deployed at one senior man place....pix was taken today. One did max 1.3kw in my presence while the other one did around 500w max.

Tdoctor:
Will a buck converter work? Any one with experience?

I get experience. E no go work.

dollarnaira:
Charge with your cc or grid at 48v then parallel them for few hours IT WILL WORK. Since battery can serve as a charger to one another in parallel. DO IT!!!

This seems to be half of the story though since LFP cells can be at the same voltage but different SOC. The ideal thing should be to parallel them and charge to 3.6 ish volts with a CC-CV charger.

They are all full when the charge current drops to a very very low value.

I also need a charger like Tdoctor said.

JoeSef0:
Aside from the fact that I can't even afford anything at the moment. But considering cost, i know a jumpstarter is multipurpose, but then a new battery and a jumpstarter cost almost around the same range, maybe few thousands naira difference but not much, I'm the type of person that sits in my car, put it on accessory mode only to listen to music or charge my phone.. I can't do that anymore because the car would probably not start due to weak battery.

Use am run some bolt or I drive runs to raise money na.

Nice one.

The cells look really well matched.

@saint2ace you built a pack? I'm in the process of building mine and top balancing is a challenge ni o.

I don't have a 3.65v charger with high amps, so I seriesed my cells to charger it up unfortunately one cell hit 4v+.

I now have them in parallel and need a charger at that voltage to fully charge them.

Would the swelling affect performance?

Stormyweather:
omo the ginger I'm getting from here is impressive. I'll start buying all these small small. Someone sells here?

Yes. Valto, Mr reed, damreh, and some others couple and sell.

You can also get from the open market, see attached. But please do you due diligence before paying for anything.

sirneyo2005:
You are on point especially top balancing currently facing top balancing issue because getting a good DC adjustable power supply is vary hard pls where did you get your battery casing can you post the link thank you

I think a bulk converter can be used.

ChngedChnges:
Thank you.
I got them from valto. You can check his jiji page for the pricing. I don't think am allowed to give such information here

Na cult??

Stormyweather:
oh wow. Not bad even though it's slightly above budget

Why get a 2.5kwh battery when you can get a 3.6kwh for same price?

Adaowerri111:
Between jinko Ntype bifacial and Longi solar panels which should I go for? im looking at getting 620W of any.

Original of both are good.

Hybrid600:
Oya Trippledots: start uninstalling and let's make some good money 🤑

E choke... 😂

jamesid29:
😄😄. I need like 14 Chief

Hahahahaaa.... I cover my single unit with da blood!

jamesid29:
Thanks a lot Chief.
Yeah victron does, I believe. I was just looking for something alot cheaper & didn't have to import, cos the project is time bound.

I'll see if I can get the Junctek in Nigeria. Or if you know anyone selling it, that would be appreciated also. Thanks a lot for your input boss

Linnov here sells, but I think he is out of stock.

I can uninstall mine and sell if you ready to pay well. 👀...come DM.

Adaowerri111:
Na 2 options dey there na

Lol...ok. but this second option get as e be. You sef know ni. 😁

Kaczynski:
better stick to using chinko knockoffs


fear of spam bot is the beginning of sense


oshey omugo obirin

Hope all is well at home? 👀

Kaczynski:
im nuh gonna stqrt spoonfeeding you


just take it as a homework and do ya research

Spoon-feeding, for a simple question, on a DIY thread 😺 You were so much in a hurry to reply that you were just throwing typos all over the place!

Such crass character display in public. Smh

lungwun:
Credible installers dey, but installation is always haphazard and ultimately ugly.

Breakers and trunking everywhere.
If we can install these things and keep wall mounted cables away from view this will be good.

Unfortunately we cant. So for confirmed 5 years warranty from a reputable place (Not one place that one tiktokers will carry me to create content because i complained about after sales service) , that Huawei ESS from Fouani is top of my mind.

It's not the fault of installers.

If you want sub surface installation where they will cut the wall, run cables plaster and repaint It can be done, but the average client doesn't care about that level of install aesthetics or isn't ready to pay for it.

Some buildings come with dedicated cables for inverter installation and that helps with neatness of any installation done there.

Btw, fouani installations use trunks or PVC pipes for even C&I level installations. I've worked with them. So buying an AiO sysyem from them doesn't mean you won't see trunking.

jamesid29:
Hi everyone,
Abeg does anyone know of any good battery monitor that has auto generator start feature.
Or is it something that has to be coupled separately?

Junctek has a battery monitor with a dry port relay switch. It can be used for gen start/stop.

I think victron and their Chinese knock off have too.

seunpinky:
Hi All,

Pls asking this question for a friend who is about to carry out a solar inverter project and got a “family and friend” quote of 1.4million naira for a 4kva system on 2 batteries. Pls is this amount realistic?

"2 batteries" doesn't say anything. Give more details on specs.

Adaowerri111:
This right here is for sale or swap with a 12kva hybrid inverter

80amps Cc for a 12kva hybrid?? How na... 😂

Kaczynski:
you better off getting tesla powerwall and a battery

How is that better ?

Seun:
I'm looking for an all-in-one with at least 5-8kw inverter and 15-20kwh battery. What do you guys recommend?

You can check this if you insist on the AiO anyways.

https://fouanistore.com/product/483?huawei-power-m-5kw-power-module-inverter-15kwh-battery

Someone has a review of it on YouTube

Seun:

Oga seun, how you doing?

Why you want to do all in one? When credible installers de here?

favouredbymercy:
What is your solar charging parameters for your hybrid inverter and external charge controller? If your charge voltage in your inverter is higher than that of the controller, what you are experiencing would be normal as the inverter will take d battery volt higher than that set on the controller.

Spot on.

FEGEITOK:
I will contact you.

Additional details:

I was correct; my Powmr 60A Charge Controller tripped off with Fault code 63, meaning it was overcharged.

If I had ever encountered this error, I would never have traveled and left my solar setup as it was.

However, I now believe this is due to overpaneling, a factor that was not present previously.

Ok...


Over charging or over voltage?
