chimoz:
I have many questions
1. Is there any possibility of getting an inverter that will use both solar and electricity
2. Recommend an inverter that on a single charge can power One 2hp ac, 40" plasma tv, one medium sized fridge and 5 bulbs plus other minor electronic gadgets like phone, laptop, music system and decoder for at most 24hrs

3. If its possible, what budget can successfully execute the project.....the battery and every other thing should be the best quality.

I need the best quotes for an inverter set up that would power the following,What size/rating of Inverters and battery can power the below conveniently:

1) 5 UNIT LIGHTING BULB POINTS
2) 3 CEILING FANS
3) 3 LG 14" PLASMA TV's
4) ONE LAPTOP

Pls get back to me asap.

chux76:
You mean the 2kw inverter and 2 batteries would power these items conveniently?
Are the batteries new or used?
How long would the battery last (fully charged) if all the above items are running concurrently?
What is your 'BESTEST' price for the whole package plus installation?

feflo:
This is the smallest solution I have for now and it will require some form of installation. This will also pick your electronics conveniently.


1200W inverter - 25k
100ah battery - 25k
Installation. - 10k

The battery and inverter are brand new with guarantee.

Many thanks for your enquiry.

A 5KVA 48VDC Solution at Femi Okunu Estate in Lekki

It powered 1HP A/C conveniently with all the load in the house, fridges, 4 TV's including a 70'' LED TV, Musical instruments etc

Hey Femi Morning,

Pls cn u send me a quotation for a minimal inverter that doesn't require any rigorous installation..jst a plug nd play range and suitable battery to power jst a room with 1 fan,2 energy saver bulbs and socket for laptop


Thanks

mrtnt: When would u hv d fairly used batteries again? I need some.

Kindly post d pic of ur 30ah charger here. I'm also interested.

Talibanis: Picture quality is terrible to appreciate. U can do better by posting pix in different views and close ups. This is the modern world with advance technology, let's flow with it.

NextDayPn: Just seeing this now, how smart are your chargers and how many hours would you say it will take a TOTALLY FLAT 200ah battery to be fully charged using a 30A charger. Thank you.

uc97: Please send details of 3kva & 3.75kva inverter to uchennapete@gmail.com.


Thanks.

Deluxe8000: pls how much is 30ah battery charger

feflo: From the above, your inverter is 12V, 600W and you use two 12v, 155ah batteries to power it. Your fridge is rated 68W. The compressor in your fridge would require up to 3times the rated watt to start and that is about 210W. Its not advisable to use the whole 600W of your inverter, lets say the usable watt is 500w. If you draw out 210W for your fridge, you will be left with 290W for other loads, personally i think its rather too small.

My advice

Your inverter can power your refrigerator but i'll not advise you to add other loads to it. If you must use other load, the total watt of the loads combined must not exceed 200W and the fridge must be switched ON first before the other loads comes ON.

Many thanks

chux76: Feflo,your candid advice is needed here.
I have been using an inverter for a while now,3yrs to be precise and there has been no regrets whatsoever. The specs of my inverter/battery combo is:

INVERTER
Maker: Mercury
Model: Radiant 1000
Input: 220Vac-240Vac,50/60Hz, 8A max, 10
Output: 220Vac-240Vac,50/60Hz,10,1000VA,600W
Battery; 12VDC

BATTERY
SEC Ind Battery Co.
Sealed VRLA AGM
CELLYTE 12FTA 155
Battery Charging
Float Voltage: 12.25Vpc +/- 0.01Vpc @ 20-25C
Max charge Voltage: 2.35Vpc +/- 0.01Vpc @ 20-25C
(I use 2 batteries)

I would like to know if it can carry a SCANFROST REFRIGERATOR with the following specs:

Voltage: 220-240V
Frequency; 50Hz
Input power; 68W
Refrigerant: R134a 60g
Volume: 130L
Climate Class: T

Thank you

mrtnt: Do u still hv those fairly used batteries?

feflo: Thats exactly what the Auto switch does, you'll hardly know when NEPA comes in or goes off. What i mean by effective management of your load is this, its expected that you'll have a NEPA indicator to tell you when utility is absent or present, also the inverter display tells you either you're on battery or utility, as soon as you discover that NEPA supply goes off, you'll have to go round to reduce the load on it. Remember the inverter can power all the load but our goal here is to increase the runtime of the battery and this can only be achieved by switching OFF devices thats not absolutely necessary at every point in time when you're on inverter alone.

Hope this answers your question and thanks a million for your interest.

feflo: 2. If I hv 1500w inverter wt 200ah deep cycle battery, hw long (average no. of hrs) wil it last for:
1 unit x 21" TV
1 unit x decoder
1 unit x laptop
2 units x ceiling fan
8 units x bulb of 60w each


A 1500W Inverter using a single 12V 200ah deep cycle battery

Total battery watthr is 12V x 200ah equals 2400W
Your inverter is not designed to drain the battery completely, assuming you only have 1800W usable battery watthours.
Your total load stated above is about 800W. This means that your Inverter should work for 3hours. Take note, when using inverter, its not expected that all the above mentioned load will all be ON at thesame time so if well managed you can have like 6hours or more out of the battery. Thanks

I will respond to the other questions later, once again, thanks.

feflo: 1. What diff. is there btw 1500w & 2000w inverter? What can 2000w do dat 1500w will nt be able 2 do? Enlighten d house.


Literally, your question is like asking the difference between N1500 and N2000. Everyone knows that N2000 will purchase more goods than N1500 but technically, a 2000W inverter has a greater load carrying capacity than a 1500W inverter. Assuming in my house, i have an Electric Iron rated 1000W, a fridge rated 200W and Ceiling fan rated 50W. My total load becomes 1250W. A fridge will require 2.5times the rated watt to start, this means a fridge will need 500W to start.
If your inverter is 1500W, its not possible for you to be using your Iron and still put on the fridge, the inverter will shut down on overload but the 2000W inverter will pick all your load at the same time. Hope this answers your question and thanks for your interest.

mrtnt: Do u also sell external battery charger? And hw much?

Lookng at 1200w or 2000w inverter wt 200ah battery, is external charger needed? And which would u recommend?

mrtnt: It's ok.


Dis issue of 'deep cycle' battery, pls, is dis diff. frm typical trailer vehicle battery? If yes, pls what makes d diff.?

mrtnt: Now looking at a typical situation where all d above listed loads are ON with Nepa light & suddenly Nepa takes light. Wt dis inverter that has inbuilt auto switch, I want 2 believe dat none of d loads wil go OFF cos d power wil switch immediately to battery source. Is dat nt what d auto switch does?

Or u mean, if Nepa takes light, all d loads go OFF? Then, I hv 2 go around d inverter & manually switch over to battery power? And then start to ON d TV, decoder, laptop, fan, etc all over again?

Pls clarify.

mrtnt: Thnks 4 your insightful analysis. Hope dis also helps some1 out there too!

However, u omitted question 3.

What good battery frm your stock wil u recommend wt your 1200w? Brand new or like-new? What is d implication of each vis a vis durablity. Hw much do u sell each?
