What r the disadvantages?

harizonal123:
This is my inverter below. Pls I would like to know if it is pure sine wave or modified sine wave. I can't find where it is written. I heard modified sine wave is not too good for electronics in the long run. How true?

mahkanjuh:
Please good people, like how much would I need to budget for a Solar Set Up if I want to power a 3 bedroom flat with 2 fans, 1 TV, decoder, sound system, 8 bulbs and a medium deep freezer

babniyen:
Along the track of this; How about NXT Index batteries. Any one with experience with them.

eleojo23:
How would you rate Gacia and Mercury batteries?

Ahyjo:
Good afternoon. Pls experts in the house should weigh in on this:
Hoppecke or Quanta or Monbat

From your experience, which is the best amongst the three batteries? Thank you.

This is the first time i am seeing a Google Pixel 2xl with a drop notch!

Thanks i will pass!!!

12volts or 24volts inverter? Which one is better? Gurus in d house please help

olatade:
Please who has an idea of what the low voltage cut-off of a 12 volt luminous hybrid inverter would be?

Horlaarsco:
I got a 150ah 12v battery
2 pieces of 150w solar panel
1kva pure sine wave inverter..


About the connection I got confused with the wires in the inverter how do they go?

tchijioke:
Fairly used and fully functional Famicare 1500VA 12v hybrid inverter up for grabs...I need to sell it off cos am considering an upgrade...Price very attractive.

olaolu11:
This battery level signal at back of my inverter, how is it used? Do i have a meter connected to it or what?
And the fan is no longer working. Can i diy replace it?

Easylearner:
mctfopt
Thanks alot...

For the spd, have seen online that is connected like a breaker but no off and on switch.. does it still need to be Connected to ground.

WalkerMichael:
This is really sad! I became sadder when I realized nothing would be done about this case (they will silence the case) - which means those behind the murder of these policemen wouldn't be fished out and made to face the law. NIGERIA IS GONE!

lexi28:
nice, I tried to cut out part of your comment to save space, nah, it didn't work. its all on point. starred.

Easylearner:
Good day everyone
Wanna ask some few questions...

How can I utilize this component correctly on a solar system

1. Mcb>> circuit breaker (do i need a circuit breaker when installing and if yes! How do i calculate for the correct rating and the right position to place it)

2. Spd>> Surge protector device ( How can i surge my device, the right way to do it and what determines the rating)

3. Fuse>> when a mcb is already integrated in a system can fuse still be used or the mcb act as a fuse...

4. Is it compulsory to use a battery balancer

5. When connecting a battery in parallel, what's the appropriate number that is idea to connect (i heard 3 column)

I'm asking before i burn my house or spoil the devices.

One fact you all should be aware of is this
"The soldiers in that video might be innocent"
Why? THEY ONLY EXECUTED AN ORDER FROM A SUPERIOR, who might have told them that the policemen were kidnappers and they should not let them escape.

The soldiers acted mercilessly with the thinking that they were dealing with kidnappers ( which let's face it we would praise them for if they were really kidnappers).

THE REAL CULPRIT HERE IS THE SUPERIOR WHO GAVE THE ORDER.

IMASTEX:
Men. That is cool just #500 for waybill. How long is the delivery time? Can one just order from any vendor on the platform or it has to be via a third party.

HRtechnique:
Those are the scam department.
Ensuring the safety of the site for buyers.
That is the entire goal.

Yes the process can be better but the calls is to confirm that you are not fake.

Once they notice your price is unfair or too low or pictures not clear or content not clear, they will call.
Na Naija we dey and they want to be careful

The above is the truth.
I sold my car on Jiji in one day when I paid for boost anyway. Never tried the free version though.

snipesdam:
Then they call you to make it look real. The same number used to call you goes incognito. This attitude shown my jiji only spoils the brand.

ojeysky:
I made sure to avoid shadows, I will try to tilt to the extent feasible. Thanks

ojeysky:
Bros so I have done the setup; could not get a bus bar for now so I used the DC breaker as the common connection point for both the SPD and PV. However I have noticed that it seem the battery consumption has increased, does the SPD and DC breakers consume power on their own?

Update nevermind the source of drain identified - it's self inflicted.

Secondly, I have moved my stuff to standalone, I was happy to see over 1kw yday at relatively high sunlight. However when it rained and after sunlight came back I lost generation, noting was coming in, I noticed water was still on the panels could that be the reason why I was not generating anything?

hi,
basically you actually need to know the overall head of water your pump is required to pull and pump water to. this means depth of borehole, lateral gradient, and height of overhead tank.

popular brands are the Lorentz, and grundfos, and the other Indian and Chinese brands
the Lorentz comes with its own controller (with inbuilt MPPT), the grundfos comes with 2 variants, the CU101 (ordinary on/off switch) & the CU200 that has added features for float switch and generator connections. these controllers usually come as one package, but most retailers sell them separately, so be careful.

when ordering the generic brands, it is best to ask for the data sheets to determine whether it suits your water supply requirements. some people self the controller from 650k and sell the CU200 for 250k. try Google and jiji, before venturing to go to Alaba. I will search for the contact of Auxwell, I think, the last reps of grundfos I know.
some guy in Alaba offered me a pump with 100m head for 130k. it all depends. if you have the funds, go for grundfos or lorentz, (which is more expensive)

I will assume the borehole or water source is ready.if a borehole with standard diameter (6", you will need the pump, 4core flex (some use 2.5mm, but 4mm is better), strain relief PVC cable, tiger pipes (1,1/4"- 1,1/5" based on outlet of pump) or ordinary PVC pipe of same size. if using tiger pipes, they have screw threads, ordinary pipes need to be glued with connectors using PVC gum. then you will need cable ties to hold the electrical cable and strain relief cable to the pipe of your choice.

you will need some kind of rack or pole mount to place your panels, depending on location/size of storage tanks. most steel tanks of large capacity have the solar panels mounted on racks welded atop the tank. if you have space, place panels on pole mounted rack away from trees or tall buildings. you connect wires from panels to controller, and connect wires from pump to controller. the controller is usually placed in a waterproof enclosure under the panel rack, but you could place in anywhere else.

your panels are usually wired in series to achieve minimum startup voltage. some Chinese brands I have seen use a 2s2p config of 300w panels, and it pumps water okay. for pumps like grundfos just check Voc of panel you want and calculate how many you need in series to achieve operating voltage of the pump. same goes for Lorentz.

cheers

IMASTEX:
Here is what I was told today at a phone vendor's place. As I inquired of a particular Nokia make, that hasn't been lunched in Nigeria. Nokia X71 (8.1 plus). "It was obvious the phone can only be ordered online from overseas" I told the vendor. Then she repied as follows:

Phone brands "Nokia" ordered from overseas via Jumia is without warranty. Secondly, It is not a Nigeria specification. Hence, There might be a challenge if there are need for repair. As the exact parts may not be readily available at the Nigeria Nokia Care Centre. Except the person send it back to the country it was ordered from whenever there is a need for repair.
Is the above claims true?
I was almost paying for the one she offered as against my desired spec.

1. What are the differences between global version & the chanise version in phones?

2. Does version have anything to do with the phone's quality?

3. I noticed a wide price gap at a Nokia brand outlet today as against the Jumia online price. Though, that of Jumia is an order from overseas. Does this have anything to do with quantity?



Please how true are the above submissions. I've been doing a little research on what brand & make of phone to purchase within a budget of 100k to 150k. Though, I was kind of considering Nokia & Huawei phones.

Mods you can help to escalate it. Really need to get clarifications.

ceaser:
That strict range of different VoCs for different voltage systems put some question mark on the efficiency. It may raise suspicion that the efficiency at all VoCs viz-a-viz the voltage system may not have a linear relationship in efficiency. Energy may likely be wasted if one goes a higher VoC that that recommended for a particular voltage system. If not for that downside and maybe a few more that may be present, these guys would have been a good value for money. They've even come up with another product with in-built WiFi for remote monitoring.

I still think of securing the PowMr just to know who between the two is telling the truth (Penn and Teller tell a lie )

The PowMr appears to have good reviews on Amazon though.
