It is not advisable to run fridge/freezer on inverters but I have a friend who does. 3 KVA inverter with 4 batteries. Also know that you cannot run it for an extended time. Get a big Gen to support it.

bisiriyuahmed6:
Please I av 1.5kva 24vot Luminous inverter and I want to buy new battery, but I don't have money to buy two 100AH. what can I do, anybody with advice?

coderXO:
Absolutely not.

FYI that reads 800VA-5kVA.

If it's the 5kVA inverter, perhaps. But it's still high.

Inverter; 200k tops
Batteries; 50k x 2
Charge controller; 40k max
Panel; 50k;

bisiriyuahmed6:
please. Help me, God will help u 2.
1 Led TV(45watts)
2 plasma TV( two 60watts)=120
1 small PS 2(35watts)
1 big PS 2(50watts)
2 wall fan(two 45watts)=90
1 flat PS 3(I don't no the watt of d ps3),

I have 1.5kva 24vot Luminous inverter, Am thinking of buying two(2) 100ah battery, I want to no maybe d 1.5kva will charged it well and with d list of load, what our can it used before it go off ?
Where to buy,product to buy and were to buy new battery in Lagos with good warrants on it?
Please I need urgent answers

Thank you for your comment. The link is correct. That Victron model goes from 800 VA to 5 Kva. The 5 Kva unit alone retails for over N500k in Nigeria. Some Inverters are more equal than others. Victron commands a higher price than SMA in Europe. That says something does it not.

coderXO:


1.5kVA will carry all that comfortably.

The charging of the batteries depends on the charger on the inverter ( if it has a charger ).

You might need to get a separate charger if you find that it does not charge it well enough.

You can buy batteries anywhere. They are on Jumia, Konga, Oshodi, Alaba, Computer Village.

Whereabouts do you live?

Assuming your total wattage is around 400W per hr, lets approximate you will drain 20Amps per hour.

You have a total of 100AH, that means 5 hours but you do not want to run your batteries down all the way or they will not last as long as they ought to.

So when you have 100AH, operate with a mindset of 50AH.

On that 50AH, your 400W will last 2.5/3 hours.

coderXO:


It's a matter of efficiency and quality.

I see respected brands like Prag and Xantrex in the 5kVA range for much less than that.

I don't know o...

chris81964:

You might want to read my original post again. Prag is a respected brand? Where? Xantrex is known but not the first choice in the off grid world.
That price included batteries, solar panel, a roof rack a charge controller, a Victron inverter and an installation kit.
I will like to see a 5 Kva Xantrex at that price with all that included. I will be the first to buy.

coderXO:


You might check on this thread for those that like prag.

That your Victron altogether price is still on the high side, prag or no prag.

chris81964:

Thank you for your opinion. I am sure their are others who share it as well as those who don't. If what you seek is another commodity then this is not the product for you. You will be better served by your Prag and Luminous. We want those who in the 80 s purchased the Mercedes 200 and not those who purchased the shinny Daewoo Racer.

coderXO:


Funny man. I doubt you had a Mercedes in the 80s. People that had Mercedes in the 80s are generally not on NL today peddling goods.

chris81964:


You are even funnier.

Marketing 101. Nairaland is a free medium to promote yourself. There are over 1.5 million members. This subject / topic has had over 129000 views. I or any smart person would be stupid to ignore Nairaland. We are looking for people who make the right buying decision. ( I don't believe a simple comment needs explaining, but I will help you comprehend what I meant). People like those who in the 80's bought the MB instead of the Daewoo.

Your present circumstance should not be a hindrance / obstacle to your future destination. It is 10:16 am where I am and we can continue to banter back and forth if it makes you feel extra special. I have the rest of the morning.

I'm not a prof when it comes to this but with the little science knowledge I was able to install my inverter myself. Now my next deal is to get a solar panel and charge controllers. Though I have 2 bps 150ah batteries, I discover that one of the batteries is not too good. I bought a 12V 1.5KVA Xantra inverter. Here is my connection bellow.
Note: I did this to control the change over myself cos I don't want to tamper with the EDB of my apartment.

I'm currently running it on a single battery. For now. Would love to know more about how to calculate my load on it. Cos after putting on everything I normally put on the inverter shows 31%load and the battery drops to 77%. With this I want to know how long it will take me on the inverter with one battery. This is my load list.
1. 2 30W energy lights
2. 4 15W energy lights
3. 2 ceiling fans
4. 42" LED TV about 150W
5. GoTV
Others includes mobile accessories.

Would also want to know if it is more economical cos I use prepaid meter.

scobyy2007:
Time (Hrs) = (Bv * Bc * EoI)/Load


Bv = Battery Voltage (eg 12V)

Bc = Battery Capacity (eg 200ah)

EoI = Efficiency of Inverter (minimum is 0.6 some could be 0.8, please contact your supplier)

Load = Total load of all appliances in watts (eg 34 + 50W)

Time (hrs) = (12*200*0.6)/84W

Time (hrs) = approx 17hrs (for a total load of 84W)

@shithapuns,
My flat screens are 49 watts and CPU are 2.7 amps don't really know how to convert that to watts, my bulbs are original ATK power saving bulbs.

All my utilities are power saving utilities cos of the pressure of light, i run a 4yrs old Jinling 2.0 KVA generator for an average of 10 hrs daily on 12 litres of fuel, earning N300 per day giving my chemist shop neighbor ( 2 POWER SAVING Bulbs, 1 FAN, SMALL TV) power 6pm to 11pm everyday.

I am not really pressed with the light issue, though if there is light i will save more on daily basis. JUST THAT I HATE THE NOISE THING OF THE GENERATOR.


I don't really think i can invest that much on inverter especially for commercial purpose but will be willing to have one for personal use mostly nights, fan, lcd tv and bulb.

I am confused on which onw to get to suit my private need, so much choice and experiences from consumers, will surely make up my mind based on the experiences i have read here next week.

fabulous01:
I have inverter 800VA and just bought a gen 1900 with 950w output.

Please will it give my 800VA perfect charge?
