Oh Johnson, so sorry for this terrible experience, but I will blame you a bit. You knew I base in Abuja, You know my capabilities, You have my number, you should have just rang me up.
But in all, has this issue been resolved?.
So sorry you fell into the hands of Engineers without Knowledge.

I had gone to correct an installation last year where an installer connected 2units of Felicity LPBF48300 in series, to 2 Units of Growatt which were in parallel originally. The instruction was to replace 8Pcs of Tubular Batteries with 2x LPBF48300. Thank God one of the LPBF48300 popped fuse immediately with a loud explosion.

The guy still went ahead and connected LPBF48300 in parallel later on without investigating the cause of that explosion.
The client later discovered that one of the batteries wasn't discharging and charging. And that was how I was contacted.

Moral: Be careful of Engineers without Knowledge.

Ferdiwar:
Mid January when I wanted to mount my panels on the roof, I contacted (a so called) engineer to do the Job (I have phobia for height), via phone call without any information on my setup baba concluded that 5 pieces of 570w panels won't work, that it's either I get another panel to make 6 or I use 4 out of the 5 and that I need 10mm with for the installation I just ended the call and reached out to another person.

The guy that later did the Job later begged me to teach him how to set up lithium battery on the inverter as he was unable to do that on the 1st Deye inverter installation he did.

Most of the installer and so called engineers are too lazy to update their knowledge on the same things the practice.

Dam5reey1:
you and the installer ehn, he didn't confirm settings with his boys, and you also didn't confirm the battery profile while on call.
Like you said we just need to be careful.

bassdow:
Quite sorry for your issue.

But you made a mistake trusting random Nigerian without due process. And dem no dey delay to collect money. In fact should you pay 100% ahead, they just might not show up at all, and even when they do, dem go dey do anyhow because they believe they've been paid and have nothing to loose.
In fact, when you pay 100% ahead, their next aim is to squeeze more out of you.
Say we dey here dey talk like say we get sense and responsible, doesn't mean we all are. Some of us just dey do packaging + hustling.

meanWhile, me sef dey do installation Ooo. I hardly market myself sha

I need an experience installer to check someone's system in Abuja.

Good day professionals and non professionals in the house. i seek for your counsels on my solar installation plan.

Sorry I many not be able to know power consumption of all the items listed below:

1 I am having haier thermocool chest freezer with watt rated current of 125W/1.2 A, energy consumption of 1.11kw.h/24h (on timer during sun hour)
2 Medium standing fridge = 1 (is on time during Sun hour)
3 Solar stove 1 (use only morning and afternoon)
4 SMC ceiling fan = 5 (only 2 can be put on at the same time in the night)
5 Flat screen TV of 32 in =1 (on all the time except late in the night)
6 Startimes decoder = 1 (on all the time except late in the night)
7 Energy saving bulb = 10 (only 4 are use at a time)
8 Laptop = 1(3 hours at night)
MY SOLAR ENERGY PLAN
I have 6 panels of 400 watts africell,
Hybrid inverter 5.5kva of farmicare product (transformer type) with inbuilt charge controller PWM with VOC 60 VDC
60 A charge controler MPPT type
Two 12 volt 220A battery

My Question
Can my solar energy system will be able to power all this when they are put on at different time of the day?2 Will my panel be able to charge the batteries within 4 hour while the energy from the panel is been used together on the freezer?
3 I need your kind advise if I am on the wrong lane?

jplambert:
The 750k can power his fridge of he goes for modified sine wave Inveter as 3kv of such is around 70k

Mind you, solar gen is not advisable because many of such generator has inflated capacity and when it get spoilt, that's the end

jplambert:
Don't buy solar generator, if your fridge is around 100watts, get modified sine wave Inveter of 3kv (price is around 70k) and your 750k will be enough to set it up. Ensure that you have circuit breaker installed on your system btw

And your fridge can't be on power at all time because it will drain your battery. No solar gen of 750k can run your fridge 247

I am not an installer or selling stuffs but just giving advise based on my experience and what I have learnt about sola so far

jplambert:
If your fan is DC

200ah battery

180w 4pcs solar panel

1kv inverter is ok since you are not running fridge on it

Charge controller

DC cables

In all, 750k should be fine to setup everything

dottedlines:
Tv- 70 watt, Light 6w x 7( lightings will not used be at same time) Fan 15w and 90w, (Both fans will mostly not be used at same time).

dottedlines:
Good morning Chief, please what set up do I need for the loads you listed below, a TV, two fans and lightings? like what should be my budget + installation? I reside in Lagos and I need this set up if cost is reasonable. Ikeja Electric don use my eye see shege this year, my consolation be say I dey go work from morning till night, it's weekends I see premium shege.

jplambert:
It depends on brand

Some good brands of 1k that cost 120k still in the market

olujosh301:
I am new to renewable energy but I see alot of solar setups
Please I want to ask for advice
Are all in one solar power generators reliable or its better to go for conventional setups?
I see alot on jiji ranging from 300w to 5000w

Valto:

low quality 16mm nepa wire for solar panels . God have mercy!

Indaboskikoboko:
Hello house. I want a system that can power two laptops and one standing fan.

How do I go about it? Or it is cheaper buy a ready-made one?

AllyPolly:
Well done professionals in the house.
Please I'm on a budget and I need a list of solar materials (with durable not too expensive brands) that I need to setup a solar system. Let's say 5kva system with lithium ion battery. I would like to buy the most expensive materials (battery, panel, inverter etc) of the setup myself then leave the others to installation engineer. Thank you sirs.

dbshaywhy:
Good morning professionals
Thanks for those that posted that fouani is now selling jinko panels, they are as well into inverter(growat), Huawei lithium battery and one other brand lithium battery, but they are much more expensive.
I need the professional input, I already have this set up

2 200w zinox panel

1 220w tokunbo panel(brand name forgotten, just added few months ago)

30a epever mppt cc

1 220ah Mercury tall tubular battery

1kva nexus inverter.

Presently I intend full upgrade to 3 - 3.5kva inverter and lithium battery of 5kwh.

1. Will 4 pcs of 435w jinko panels mono facial suffice full charge?

2. Is it advisable to use an hybrid inverter in terms of durability, efficiency and stability, if yes, what brand?
3. Can I still use the former set up alongside, the panels and the cc excluding the battery and inverter... Thanks for your input

Allem:
Good morning boss, how many watts do you get from this 700w panel at peak? I have 3pcs of 160w and 2pcs of 150w all in parallel totaling 780 but I only hit 300w at peak

Edrizz:
You can't compare a tubular battery to a dry cell battery, the former has 50% DOD while the later has 70-80% DOD

jikaseo:
How much would this set up cost sir?

guente02:
I've moved on from that Inverter, I just want to get another one with better quality.
Who can suggest a better 24v inverter, I don't even want it to be hybrid.

Joyprime:
I need review of this cloud energy 1.5kva hybrid 12v inverter

They said they have free service center under warranty.

People who have used their products pls help

mvphenryeto5:
Used or new?

Jefferyzz:
No
It's a complete BMS but non smart
Buy if it's still in stock of d seller might b old price

isangjohnson:
Boss, I guess you should have checked the post of someone that suggested 180w pv and 40k cc first.
From his post, 40k cc is pwm and 200w and below is very compatible with it.
It's very wrong to use 300w with pwm cc.

bassdow:
wait Oooo, He's refering to a 12-volts system.

You see, my response was along the lines of "if 300Watts solar panel would work with PWM charge controller". Not the scenerio you posted above.

Trippledots:
When using a PWM controller, for a 12v system, ideally your panels should not go beyond 200w per module except the distance from PV to your controller is very far.

If you want more power, then you parallel more panels of same range and make proper cable provisions for minimal voltage drop before power gets to the battery.

Recommendation:

1. Buy an MPPT controller
2. Change your panels to 200w units and parallel them, then sell of the 335w modules
3. Buy more 335w modules and parallel with existing units.

Note that apart from the total load on your system, in this case 150w, how long you run this load(s) on the battery and time of day also matters aka load profile.
