You should calculate it as follows:

Energy Audit:
- 55 inch TV : 120W
- 32 inch TV : 80W
- 2 Decoders : 60W
- 5 Ceiling Fans : 300 - 375W
- 2 Rechargeable Fans - 100W
- 4 Laptops - 400W
- 1 HP inverter AC : 500W
- 15 Bulbs : 75W
- Freezer : 200W
- Pumping Machine : ?
- 8.5kg Washing Machine : 1.5Kwh

From this clearly you need at least a 5kwh inverter and 6kwh to handle thr surge of your washing machine.

Second is average nighttime load.

If you run all ceiling fans for 12 hours that's already 3KWH. If you put on lights for at least 5 hours that's 325W. If you watch TV for at least 6 hours that's 1.5kwh. So you need a 5KWH battery minimum.

Then to run your daily load of at least 8kwh and charge your battery of 5kwh you need at least 4.5KW of Solar panels.

Summary:
- 5Kwh inverter : N 550K
- 550W panels x 8 : N1m
- 5Kwh LFP battery : N1m
- Wiring & accessories: N 200K
- Transport: 100k
- Installation : N 150k

Total: N 3m

Good day professionals in the building. I am trying to assemble a small 2.5kva solar system.

Please how much can I get the following items .

12v Tubular battery x2
Afripower or Haustrom 2.5kva 24v inverter
Mppt charge controller
4 300w Tokunbo mono panels

And which brand of Tubular battery can you guys recommend for me . I am using Genus presently but it's out of my budget for this project

Stumbled over this recently and I don't know if the price is right---442k with 200a smart bms

But seems Valto or Mrreed is cheaper.

Ok, there are 2 things involved.

It’s either you set your charging current on the controller to 20Amps. This is why you keep getting 280watts at most (meaning it is charging with the battery voltage of 14.4V-14.8V and a current of about 19Amps).

Or your panel(s) is bad. If this is the case after you have confirmed the first reason above, I urge you check the open-circuit voltage of those panels using a multimeter, as well as their short-circuit currents (better call a solar person around to do this for you if you are a novice). This will let you know if any of your panels is bad or not.

HawkTuahGirl:
Na someone using the same controller fit advice you. That controller almost ran me mad.

This is what I simply did: Disconnect the battery cable from the cc and reconnect it after some minutes. The controller will automatically pick the battery best settings: And also check your batteries connection is well tightened (if it DIY battery, you have to check connector from inside the pack to see if the nuts are fitted very well).

The controller is designed to work automatically without tampering with settings. I hope this helps

BigDickProblems:
What is the Rating of your Charge controller?

BigDickProblems:
Charging at 19amps, and a charging voltage of 14.7V-14.8V (it doesn’t need all the 31V) is what gives you the 280watts. Besides, is this not enough to charge your battery ?🙃.
Lols. You want fast charging 😜.
Doing the maths 280watts will get your battery full in 4hrs and 30something minutes. Practically 9am to 2pm.

There is nothing else to add since you didn’t provide enough details. But it would be cool if you provide your panel(s) specs and configuration.

This Odu is not stable for gaming
The speed is good, but while gaming it's fluctuate too much

Tdoctor:
Abeg people,
This is my first lithium build and the cell voltages are doing as they like, even with the so called balancer that came with the BMS.
I want to ask a question for those with experience:
1. Is using a separate active balancer OK, even with the BMS balancer?
2. How many amps active balancer will a 15 KWH battery require?
3. Is there any advantage with a smart active balancer vs. a dumb one?
-
NB: Still balancing out my cells, but I do not know if the 2A supposedly active balancer will be useful if any imbalance occurs again.

Lol.. while downloading I was streaming football on my and my wife busy with tiktok , without a problem

Segun2222:
you watch with data on smartphone ,smart tv etc

Hullabaloon:
You are correct. Never had a problem with downloading. If it's a very heavy file, I'll just do it overnight. But streaming was a major problem, especially live matches. All the apps I have, them Cricfy, Sportzx, and HDstreamz, would only stream without buffering if set to the lowest piss poor quality and buffer heavily on decent quality. Probably an issue with the sever on those apps.

Till I discovered this YouCine app. Has all the major super sports channels and the resolution is 480p which looks very decent on my 65 inches. Absolutely zero buffering on that resolution. Finally my streaming worries are over. You can give it a try.

Anelka2021:
Downloading a file of 2.9gig In 26 mins is not bad

pheranme9:
Active as usual

NSEstudent:
I use ZTE. My speed is nice during the day.

Tonight I am struggling to stream UCL

seepanel:
thanks but what of tubular batt

NSEstudent:
No to both questions?

NSEstudent:
You downloaded VPN in your TV or you have router level VPN?

Segun2222:
come and test test my streaming service free for 24 hours

joekenb2k4u:
Both on my TV and phone ,but is doesn't open the iptv

Hullabaloon:
You are very correct. I was getting 60mbps on mtn yesterday normal data, yet I couldn't stream premier league match at decent quality without it buffering. Tried another app and it was streaming well on HD resolution but no English commentary. Frustration wan kill me.

Thankfully nepa brought light and I switched to DSTV

morikee:
Likely unstable when doing the readings even on video stream quality it might buffer or might be a glitch in the readings

dustmalik:
Most times, I get the full 50Mbps speed. I guess yours is not mounted outside, right?

NSEstudent:
That position is the balanced optimal point I can get within the location. Other mounting points would require taking the ODU outside, which I don't want.

Yes, I locked 491,3256. The signal is always available here. The SINR value ranges from 18 to 23.

When I was using X25, SINR was rarely up to 8 on the locked band7, but it was decent and did well. When I first started using the ODU, the band7 was performing well, but I think Airtel became worse in the last few days.

NSEstudent:
Please are you able to visit pexels dot com seamlessly?

Did you connect through dynamic mode or you set up the static IP option?

I don't know why Airtel is struggling to open this site in all my routers. I have to always use a VPN before it works well.

dollarnaira:
"Hot sun" everywhere even those with 1 panel will raise high shoulder while those with "over" panels will have their batteries fully charged too early especially when not home. Lifepo4 hates cells staying at fully charged state for hours. Plenty energy without use.

This period my fans and freezer will run run run till battery drain to norminal voltage or 20% bc the next day it is guaranteed that it will shine as early as 8am. This year's weather is the best ever---after rain, come the sun few minutes later--- unusual climate change. Free energy sweet jor

paparazy06:
If I switch to physical SIM, Will it work on normal phone if not, will it work on Airtel 5G router.

Kindly Note: The esim is for Airtel ODU

SilverG33k:
I have a 4g router i bought 30k not up to 1 week that i want to give out, if you’re in lagos and interested, use dispatch to come pick it up, i’m on the island
