These are my personal thoughts

1. The quote has the barest minimum materials for the installation to work on paper

2. The prices quoted would get you average products, not that they are not good, just preference.

3. Ensure you know the exact warranty on each products .... Just to be save.

4. Lastly for your panels if you do 400W+ it will be helpful especially for your pump, as even 400W x 6 = around 1.5KWp under NoC.

Pojomojo:
Please, what are you honest thoughts on this quote? 3.5kva
3kw 24volt Hybrid Inverter Setup + Solar

1. 3kw 24volt Hybrid inverter (80Amps MPPT) = #260,000

2. 12v 220AH battery 2pcs = #165,000 x 2 = #310,000 (Tubular battery)

3. 300watts Solar panels 6pieces (1.8kw) = #75,000 x 9 = #600,000

4. Solar mounting rails on roof and its accessories = #24,000

5. AC & DC Cables = #90,000

6. AC and DC breakers, MC4 connectors, Trunking, breaker box, Input AVS, DC Surge, ChangeOver. = #50,000

7. Logistics to site of work = #25,000
within Lagos

8. Installation = #60,000

FEGEITOK:
Your point is that the one with the IR sensor may be more expensive to deploy, but less expensive to run.
Yes! Due to how frequent it comes on.
Thanks.

What's the wattage of the one you use? 20W & 50W

And how much area does it cover? Up to 9m for 20W & 12 -15m for 50W

For the front does 1 do? or do you use 2? Depending on how big your frontage or area to be covered is.

Thanks so much for sharing.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 9:10am On Dec 08, 2022
For your setup, 50% of your loads are On & Off so that makes sense.

But I will suggest going for 6 pieces of 400W (Jinko, JA, Canadian, ERA, Yingli)

Assuming your inverter is a wide PV input inverter

For your battery reach out to Valto or a jos guy mentioned several times here.... You are sure to get warranty on the batteries.

You can call me with regards to having your setup built to standard, that suits your budget. My Contact is on signature

Hello,

I need help verifying this setup plan..

I have a 115w chest freezer
13 12w akt bulbs
320w blender (won't be used everyday)
Pumping machine 1hp
Washing machine (will get soon - I am guess 400w)
Charging phones and laptop

For this load..

I want to setup a completely off grid solar installation..

- 24v 3.5kva Novel hybrid inverter
- Five 400w solar panels
- 24v 270ah LiFePo4 batteries


Please let me know if this setup is okay..

I am open to recommendations of better products to buy and from who to buy..

Please recommend best product and from whom to buy..
Thanks..

Good morning! The mureva lights are divided into three types and they come looking aethesic and of low energy consumption with a good brightness to go with it.

One stands out of all, which is the one with IR sensor.

You set it to work without human interference and to also act as a security light by coming on or off using its ssensors.

Hope this helps?


FEGEITOK:
Please more details.

Very little literature online.

Lots of videos but none in English
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 11:27am On Nov 13, 2022
No! they don't but i don't know your source

but my source don't even sell that low and only 450W is the only one available and is the real deal thing.

Jefferyzz:
Yingli sell rebranded?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 6:17am On Nov 13, 2022
Watch out for those panel prices you are calling, it be a shame that you are been sold a clone or rebranded panels for the price stated.

These your prices don't reflect present reality.

Jefferyzz:
Unless u don't buy ur items ursef. Every item inside that paper is expensive. Just last week I called a supplier for 3.5kva inverter with AC charger n she said it's 185k. 2.5kva is around 145k. N it not even a transformerless inverter. That charge controller he won use nah those regular pwm.
Brand new panel 300w in alaba is 74k. Yingli own is around 76 I can go on and on. Dey try enter market n know price. Nobi weitin people tell u u go believe everytime.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 6:13am On Nov 13, 2022
From my own view

it is a small setup for Basic loads like
light, TV, Fan and phone charging

While it features a Lithium battery it is design to be discharged sparingly for times when the grid is down for short time so you can have power to run above mentioned loads.

Also note that no solar panel is included but a 2000W inverter, 100Ah 12V lithium battery, 30A MPPT controller and a 5A 12V charger

So in conclusion, it is a good buy if you stay abroad with a stable grid. Hope this helps.

if you can get hold of these pictures share them here for more advice
1. the sticker on one of the CCTV
2. The sticker on your DVR i.e. if used
3. The power supply
4. your fencing security apparatus too.

All these is to ensure you get the best even out of little.

Below is an example of what to look out for.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 12:36pm On Nov 10, 2022
Why not go for the PowMr sold locally and via a member here, the newer brand even has a wider voltage range.

better than sourcing abroad.

Good evening gurus,

I have been looking for a good MPPT Charge controller and I came across this on AliExpress with the following parameters

Is this a good MPPT Charge controller as I am thinking of buying it but I need advice from the experts in the house.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 12:34pm On Nov 10, 2022
@ toyeoye
In addition to this, i will recommend schneider "Mureva Floodlight" they are quite versatile and can be on but without light, can perform a lot of function. you read up more of them to get better understanding.

samnaija:
You are pushing your system to know it's weakness, that is how you will eventually have a better system.

First and foremost 48v system is more reliable than 24v system. If the system is new add extra battery to make it 48v.

Fence light and flood lights, all on why?
To avoid issues with security lights , I got the solar security light . They are even brighter and they are timed to come on , at sun down. They become dim when there is no movement around your compound, but bright once it senses movement.

Your fridge, whether it is a low energy consumption or high is a big no for 24hrs use.
Personally I will go for a deep freezer low consumption, use through out the day, on solar, switch it off by 5 or 6pm.
The chill within the freezer can carry you to next day you continue story .
I got rid of my big fridge, when I noticed issues.
In renewable energy, live like a king when the sun is up, avoid unnecessary load at night.
Also change your charge controller.

Good morning Guys, i will be hosting a Twitter space on saturday, it is basically a how to guide/education on what to expect, what frame of mind is needed before shelling out some cash to avoid mistakes of having an improperly designed solar system.

I hope to see some of us that may be chanced to grace the event and share their thoughts so that everybody pick a few newer ideas to take away.

I will be joined by Sintolord, trippledot and bigbrovar on the space.

Don't miss out! See you this weekend, Don't forget to set your reminder.

In addition to what valto said

If you can list out your usage pattern, it will go a long way to decide what works best.

dbshaywhy:
Good morning professionals...

Please... I need the professionals input on this...


I intend going for lifepo4 (to be used with light appliances, no freezer, no pumping machines, no iron.... Just the bulb light, tv, sound system, phone charging, fan and blender to blend occasionally).

I already installed;
2*200W panel
1pcs 30a epever tracer 3210A(the old model)
12v 850Va nexus inverter.

I will mostly be using the system in the night till daybreak from Monday-Saturday.... And use day and night on Sundays...

So my questions are;

1. What sise of lifepo4 battery do I really need?
2. What are those things do I need to replace or change to meet up my proposed new set up?
3. What are those things I really need to upgrade?

I want an everlasting and reliable set up as the former set with 2*100ah smf battery nva lasted a year.

Looking to seeing the changes in our discussion.

More power to your elbows.

Valto:
thanks bro. the total weight is about 90 to 92kg. even the 200A daly bms inside is huge and very heavy grin, there still room for improvement in my next metal box build.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:52pm On Oct 05, 2022
I don't know what load bearing of those AC outdoor support are but I am not sure it can bear it considering the weight should be close to 100KG+

You might need to do something DIY and the wall been very strong too. Else placing it on the ground would be the way to go.

coldcandy:
Nice.
Can a wall hanger (the type used to hang AC radiators) carry it?
What is the total weight of the unit pls? @Valto
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 5:39pm On Oct 05, 2022
I'd like to commend Valto for his thoughtful ideas in his business, the battery box done for a 280Ah used for a member here was quite rugged and robust in it's structure.

No rickety sounds, all joint very solid and no gap for large particles of dust to enter.

It even held up to 60+ kg body weight and it withstood such heavy weights of the battery, all i can say is well done to him. This is my review of his build, and the circult breaker used was sized appropriately.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 5:26pm On Oct 05, 2022
As valto has said earlier, you should take these things seriously as they add little complications to a system.

If you are an installer recommending brands like DEYE with 5 years, Growatt with two years or even victron with transformers, if your pocket carry am would go a long way to help you achieve your goals.

Ikiriye:
Longevity especially
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 4:01pm On Sep 29, 2022
You will need between 2.2kva 24V inverter - 3kva 24/48V inverter.
Just as someone as advised if you can give an estimate of how their usage is in hours during the day and also night time, then it will a long way to briefly give you what will match your needs

Good evening Bosses in the building,


I aspire to set up solar inverted in my 3 bed apartment. The solar/inverter is expected to power about

I don't know what and what I will need to buy o
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 2:11pm On Sep 27, 2022
First the smarshunt allows info to be transmitted via cable "V.E Direct" and also bluetooth

The alternate integration different from its native use is via Econcms used on rasberry pi and Hybrid Axpert variant inverters, my knowledge of its use is limited but i believe you can get it to do lots more anyways, especially the SoC based on certain set parameters.

In case you get to solve this before i do based on info above, kindly reach out to get a hold of the smartshunt
MontyNG:
Good morning guys.

Is anyone here using a Victron smartshunt? I need to know if it can be connected to an inverter to provide the inverter with details such as temps and an accurate SOC for the connected battery

If it can, then I'll be looking to buy one so please let me know if you have for sale too
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:58pm On Sep 27, 2022
NiyiOmoIyunade has already said it in a more simpler term, from the cable sizing to choice of inverter, charge controller and a few other things require that the system be reviewed.

Probably the inverter was randomly oversized, with knowledge learnt here so far, i think it is comprehensible to help try a DIY audit by noting nameplate of appliances to be used and if these seems out of your deep you can try the link in my signature, it might be of help to you.

Answers to questions

1. you will need 60A minimum, as for brand you will need to talk to valto ..... he has a adjustable lithium charger

2. 80A will be a good start, as for brand ...... you will need one that can record and allow for parameter edition e.g. victron if with enough budget, Epever, felicity, and a few i can not remember

Tommynaku:
1. As I plan to also use grid to charge the bank, what capacity lithium charger do I need? Size and brand

2. Do I need 60A or 80A Charge Controller for 2.8kva /8kwh banks? And what good brand CC can you recommend?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:12pm On Sep 18, 2022
1. Buy a good MPPT charge controller with editable settings
2. Use a BMS with editable settings over bluetooth and if i can trigger a low battery signal, so you know when to put if off

Tommynaku:
Please Is it possible to use a Luminous 24v/2.8va Inverter with a lithium battery bank of 8kwh.
Please explain how to go about it if possible as I intend using Grid and Solar
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:02pm On Sep 18, 2022
if you reduce your fan from normal ones to DC/ energy saving types then it is possible that you get a starter package on your budget with lead acid

considering you will need a
1kva
220Ah/200Ah Tubular
30-60A PWM charge controller
300W [150Wx 2]
other materials void of basic protection for your system.

you need 600W to charge the battery but with a fair grid supply you can run with this till you can increase budget.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 12:51pm On Sep 18, 2022
you did good with this installation, all i see is improvements in your ideas and skills ......... happy for you.

what i believe you should do to maximize things is

1. introduction of 275Vac SPD [Budget] or a Midnite 300Vac SPD to all incoming AC connections to the inverter area, ensure you have a good earth connection to complete thee SPD install

2. introduce 600 - 500Vdc SPD for both your inverters since they work with solar panels, also a DC breaker from panels to inverter incase non was present.

sure others will have a thing or two to say.
More power to your elbows

Since your average peak load is fridge and other peak loads are occasional use, I'd suggest you stick with a 3KW OR 3.5KW hybrid inverter

Felicity have a 24V battery too that you can explore.

2,400Wp of Solar PV
Moneyboyz:
Hello, so I wanna join the solar community,

I need to power a fridge (just to make it chill and put it off) and most importantly a washing machine, pumping machine the rest are just led bulbs and rechargable fan.
Not like all would be in use at once.

So I have eyes on a 24v 5kw felicity lithium battery.
I want to know if that's is enough and how many solar panels I will need, the type of charge controller I need and the inverter needed to make this happen.

I would he happy if someone can give me a quote for this.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:43pm On Sep 09, 2022
Add an extra 200W panel to provide adequate charging but if with very good grid supply ... You disregard this.

dbshaywhy:
Professional... What do you see to this:
2 - 200w solar panels
40 amps cc(PMW)
850Va nexus inverter.
This is the materials I currently have with tow dead 100ah battery... Now I really wish to upgrade to lithium battery....advise needed.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 9:16am On Aug 20, 2022
Load sizing will be a determinant

Then

How fast you need your battery banks to charge - which is where PV array oversizing comes in.

How long you need your loads to last for either
Normal operation hour, one day autonomy or two days ... Et. Cetera

And even the battery sizing requires more PV too as regards to charging .... Hope this is helpful?

sethtsadopp:
I'll like to know, when planning an off grid system, should more focus me on a bigger battery bank or on a bigger PV Array? And Why?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:17pm On Aug 17, 2022
Allocated only few hours during peak between 11am - 1pm ...anyone that miss the memo can try again the next day.

As 1. You PV cant charge your battery full as still you dey throwa the small charge

2. Watch out so you don't shorten the lifespan of dem batteries.
