[size=14pt]my brother, I think say na only me see am, 273k buy one plot of land for my village [/size]

danose99:
are you absolutely ruling out the use of local power from the national grid?

doskie:
for your inverters and solar power installation; www.nitramfrost.com thats the best in lagos Nigeria.
for 1 complete year now with a 10kva system. I do not know what 5 mins of power outage feels like. or call 07030222860.

ideology:
nothing does you, go ahead ahead, but Be sincere you can easily sale 1. 5kva here than 10kva

adeaks:


Can you give an idea of the cost of setting up the 2.5kva inverter?

bigtt76:
Solar panels is the best option jaaaare. Please can you link me with your guy? Want to know how to go about mine. I want the same too. Thanks

DMerciful:
Make sense. But doesn't ur fridge reduce the backup time.The beauty of solar is that its 25yrs lifespan at least.

bigtt76:
Nice one. Please can you share with us the circuit diagram showing how you connected yours? I want to know if the solar panels supply your house during the day and cut over to batteries during the night.

Usual connection is to draw power from the battery all day which to me kills the batteries prematurely. A y thought here would be appreciated.

DMerciful:
It can get you a mopower or sukam 900va inverter at about 26k and battery about 55k. See!

amokemi:
I invested in inverter last November and I wished I had done it earlier. Except for this past week when Ikeja electricity company did not supply power at all that I had to use my generator, the inverter has been my saving grace. I could sleep well during this terribly hot period despite the heat cos of my inverter.

@op, I have a similar inverter as yours, 1.5kva Su-Kam but with two batteries, I noticed what looks like a meter on the picture you posted, is that meter used in determining the charge level? If yes, how did you achieve that please?

bigtt76:
Ok but it could still mean the company connected the Solar panels to your battery charger direct and supplied the house from the battery through the inverter.

Ideally it would be best if your house I s supplied during the day from the solar panels and the battery charged through this route while at night the battery supplies the house. So it means your battery discharges less than it would if connected otherwise.

Some appliances such as fridge or freezer can work during the day on solar and turned off at night to power other appliances which are night use so power can be optimized correctly.

Looking forward to the diagram. I would be very grateful.

It's kindoff a simple process and wiring diagrams are available all over the net.

It's not like only solar works at a time and only the batteries work at another time, well except for night time when solar power is 0.

Now, lets say it's 2pm in the afternoon and your solar panels are producing 400watts and you want to power something that only uses 100watts, what happens is that 100watts of that power is forced to your inverter to run your load, while the remaining 300watts charges your battery.

Now, lets say you are still producting 400watts of solar by 2:30pm and you want to run something a bit bigger, like an electric cooking pot of 800watts. Your solar power would provide half of your load power (800watts), while the remaining (only 400watts will come from the battery). As you can see, this is much healthier for your batteries, pulling only 400watts than it would be to pull the whole 800watts alone from the battery without the help of the solar panel.

Of course at night, your solar input would be 0 and your batteries would have to pick up the slack for all loads in your house.

As per connection, there really is nothing special. You just go from solar, to charge controller, then to the batteries. However, safety features like fuses and breakers need to be taken into consideration, as well as wire sizes, distance and so on.

DMerciful:
You have a lot of ideas....nice. Some solar charge controllers have auxiliary outputs that can power a relay which in turn can be made to power specific load like freezer. Now as night comes, the charge controller can no longer power the relay which in turn will shutdown d freezer from d inverter system however once mains is restored, it switches d freezer to mains. I can design such a system..contact me on chyke200@gmail.com

waziri4biz:

do u think before u post or u just post to contribute something to the thread because ur point is just not important. U need uninterrupted power supply are getting that u are saying no to inverter

johnnday222:




bro....
how much does this your 10kva cost.

adeaks:
But 273k is something else o.

Can 100k get someone a reasonable inverter for just a mini flat?

parlondy007:



I will suggest you first take a comprehensive load analysis with your critical load point in view, after which the inverter sizing is determined. Secondly, you also know how long you intend to use the system and at what time per day. Thirdly, you find out how often you get the national grid power supply per day to determine your battery how your battery is charged. This is where the option of including a solar PV comes in. Cos if you have 5-6 hours of national grid supply per day you may not need a solar PV, that will be a waste of resources. This also depends on your power consumption, I mean the loads running at the same time, power management while using this system is one thing that must be considered. Solar powered inverter system is designed by the individuals requirements. You only regret when a careful study is not done before starting the project...

DMerciful:
For a well designed system, the batteries stay averagely for 4 years. Some special batteries last over 10years. Sinecerely you cannot compare inverter cost and the benefits

princefaculty:
Its a good back up power system I agree with you OP. I've had mine, a1.5kva with two batteries for almost three years now, it has been very helpful.

In my own case I spend no penny on gen as I detest its noise so I rely on PHCN and my inverter which often take me minimum of three days if fully charged with my electric fan, four lighting points, and my electronics.

Hoping to get solar panels installed soon

DMerciful:
In a month I normally use fuel worth N8000 to power my generator anytime there's power outage but since I bought my inverter more than a year ago, I spend averagely N500 per month. Yes..N500 averagely as I could go for 3months sometimes without putting on my gen. This backup system has been very helpful especially now that there is poor mains supply and fuel scarcity with exorbitant price. Those of you complaining of excessing estimated bill, you can get value for the bills you pay if you have a backup system since you'll massively utilize the mains when it is available provided you can have light at least once in two days.
Below is my 1.5kva sine wave inverter and 4batteries system.
Show us pics of your backup system and tell us how much you save from this arrangement per month.


Mods pls move to front page so Nigerians can be aware of alternative cost saving power

DMerciful:
I bought the batteries zenith 200AH x 4 @ 52k each. The inverter is 40k then, maybe 50k now cos of dollar . The rack was about 15k. It is good to install with a stabilizer for protection.I use 5KVA stabilizer although I have it before....all in all about N273k

GreatManBee:
Can this power a refrigerator?
If yes, for how long?
How about washing machine?
