Best to run a dedicated 110v line/sockets , connected to a central Step DOWN transformer close to the DB. Have been using that kind of setup at a place for more than 20 years

ozone0801:
Electricians in the house, I have a question?
How best can one use electrical devices like TV, freezer that uses 110-120V in a house( I want to buy some appliances, that are all 110V, cos they're cheap). Is it by using plugin wall socket step up transformers? If yes, does this work well with inverter?

Is it possible to run a wiring for a new house such that you can have wall sockets with option for 110V and 220V appliances? If yes, how? Is it through separate conduit wiring, or use a central step down transformer from the DB.
Kindly advise.

How big of a step down did you install at your place?

We have numerous ones. One for each building, most are 5-10kva in capacity.
I bought one independent 5KVA last year. That was for a specific 2.8kva machine.
You have to determine the load you want it to carry and determine the capacity.
I will advice that you give a good head room for future additions if you want to use a central unit.

**Rarely used as seen on the odometer kilometer, converted it, tested few times but didn't have time to keep up with it

So this market still never sell !!!


I recall saying something to which you took offence BUT issue be say, someone must tell you the actual truth even if you no wan hear am.

Wonder the drunkard wey go spend N750,000 on that gory image I dey see and more interesting, e no even get battery.

Las las, e get reason why "...didn't have time to keep up with it"

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

Please always include your max budget so people put those into consideration while making suggestions

thought most people in here said 350watts Solar panels, and even 400watts are old school and should never be used or does that only apply when it's said by @bassdow ?

AyobamiOluwole:
Pls Any idea if I can get this plastic fan motor axle repaired or replaced by myself or should I jejely take a long trip to Arena at Oshodi?

@bassdow and co

anyOne who repairs fans both AC and DC should have that. Except Oshodi / Arena is closeby, not really worth the cost of transportation.

You didn't tell us what's wrong with the current one as it might still be useful

It’s broken. Look closely you will see that the white plastic that clips the fan blade is broken.

doesn't look like it should affect the working of the fan thtough might be wrong BUT have you tried using it like that to see if it's affecting it.

Either way, my response earlier still applies should you really need to have it replaced.

If you got the broken piece, super glue + sharp sand should do a good enough job if you willing to go that route else either use it that way or have it replaced. The choice is yours

You made a good point. Anyone willing to put 750k on that thing must be minting money in his room.

Thanks Bro, I had to get it from a fan repairer in my area. #500.

The system already has some 350w installed! And we can't trow them away

Please I need your assistance and suggestions. Due to light situation in my area, Enugu State, I'm thinking of solar as backup. what capacity and brand 'of inverter, battery, and solar panel will be required for 2 TVs (55inch & 32 inch), 2 decoders, 5 ceiling fans, 2 rechargeable fans, 4 laptops, 15 bulbs (5 watts), 1hp inverter AC, 8.5kg washing machine, pumping machine and 259L freezer. I intend to only to use the solar system as backup to NEPA. The heavy load appliances such as washing machine, AC, pumping machine & freezer will run only during the day (10am - 4pm).
Also, a rough estimate on the cost implications will be appreciated.

Repeatedly, we have suggested people accompany their Maxumum budget along requests such as these so we don't waste time making suggestions that wouldn't be useful to the person asking.

What is the size of the pump? Do you intend to pump water using the solar system or only with light since you said it is just a backup system?

I intend to pump water occasionally with solar as its just a back up to normal grid. The pump is 1hp

Boss, sorry oh. Maximum budget is 2m plus, though it's flexible

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

From my experience, the starting surge of pumping machine is very high. So i cant recommend a 24v system for pumping machine anymore. Just look at a 48v system. If you can leave out the water aspect, then a 24v system would do just fine.

I use my 24v inverter to pump water with zero issues.

Its not. Have been doing this since 2017.

1hp submersible? Which Inverter u dey use? I believe U make use of a good inverter na, not all these chinese branded inverters always having powerboard issues.

I'm not sure about the pump's rating but under regular usage it draws around ~1.3kw. Inverter is a 3.3KW SRNE unit.

The 4.2kw inverters on the market should be able to handle a 1hp pump no matter what.

I use 24v Haisic hybrid inverter. Great inverter, very silent. No issues with even 1.5hp submersible.

If it's their 4.2kva, it isn't silent oooo both while charging alone n when load is used on it....
