Please send details of the cost/installation for 3.5kva stand alone and kindly advice me too on what it can powered at any given time.. Thanks

My email is goodness.obayangbon@outlook.com

I have sent it, the appliance it can power are all in the quote

please can you name the brand of TV quoted here, or were you assuming that the TVs would be in Low energy conservation,
my 43 Samsung (plasma) pulls 150 watts (watts meter reading) in eco mode, I am currently looking for a brand that would be able to conserve as such. The best of same sized LEDs i got were rated 80 watts, these pretty much higher than what you quoted. .

The poster didn't say the brand of the TV, so I used an energy calculator.
energyusecalculator.com/electricity_lcdleddisplay.htm

However this calculation is based on simulation. When it comes to live installation, an energy audit will be carried out to ascertain the true watt of each appliance before operation

trendyprettygir:
Just seeing this.

Please can you give me a quote for a 3.5kva inverter inclusive of batteries?

Will a 3.5 kva carry a refrigerator?

Yes with even freezer
Send me your mail

kenazuu:
still waiting for your quote.

2000 kva cabt power the load listed above only the 2ph ac can take more than that 2kva

If you noticed in my calculation, i didn't include 2hp Ac. The poster says he already has 10kva generator, that can take care of Ac.
When it comes to solar i always avoid appliance like Ac, inverters are designed for light loads

STEKENT:
please I need estimated for 1.5kva and 3.5kva

I can only send one
Check your mail

Thanks man. Pls how much will these cost including Labour.

I might get banned for posting current cost,
I have quote for 1.2kva, 2kva and 3.5kva solar system.

Just send a mail to u.charpell@afsenergies.com to get any of the quote

This quote is enough to make anyone interested in solar to understand what is needed for any load *thumbs up*

One question though, what effect does the amperage of the charge controller have on the entire process? Would a smaller amperage reduce charging time? Why did you not include it in the bolded calculation? And shouldn't the battery energy be 400AH @ 24V be 9600Wh?

Each panel has a constant amperage it delivers, the more panels you have the bigger the size of charge controller to handle the current.

If you use a small controller, your batteries won't charge properly and will burn out in a short time.

There is controller in my calculation, I mentioned it twice.

If you combine 2 batteries in series.
(12v, 200ah + 12v, 200ah) = 24v, 200ah.

The reason why we use series is to obtain a higher voltage, thus 24v

The energy energy becomes 24v * 200ah = 4800wh

ASL33:
Am finishing my small house soon hence planning ahead on how to tackle the issue of power failure in our dear country. Right now it seems the power supply will not get better anytime soon so my quest to provide it myself.

First lets calculate the total wattage of your appliance. I am going to remove the Ac from the equation for proper audit

65 inch led tv, 67 watts * 1 = 67 watts
42 inch led tv, 45 watts * 1 = 45 watts
32 inch LCD tv. 11 watts * 1= 11 watts
Deep freezer, 500 watts * 1= 500 watts
1 normal standing frigde/freezer. 300 watts * 1 = 300 watts
Electric bulbs 20 watts * 10 = 200 watts.
Fan 50 watts * 3= 150 watts

Total = 1273 watts

Recommended Inverter 2kva @ 24V
Controller choice = 40A @ 24V
Battery capacity = 240AH
2 batteries of 200AH will be required => 200AH
Battery Energy = 200AH @ 24V = 4,800Wh;
For a panel of 200W X 7hours of sunshine = 1400WH
No of panels required = 4800/1400 = 4 panels


Solar System Requirement
2.0KVA @ 24V Inverter
30A @ 24V MPPT Controller
200Ah @ 12V Battery
200Watts Mono Solar Panels
PV cables (4*4mm²) 20 meters
Power cables (1*10mm²) 20 meters
Circuit disconnect
Panel bracket (Rooftop/ground mounting type) 1 Set

Hi pls send the analysis for stand alone and hybrid for 1.5kv and 2.5kv.
For a 2 bedroom flat with 2Led TV,12 bulbs,3 fans, 2 1hp ac's, 1 fridge....with a possibility of a small waging machine and a portable steamer machine. Though not to be used at the same time.
mcmeffyklothyn@gmail.com.
thank you.

You cant use 1.5kva or 2.5kva for all your appliance.
If you want to use 2 Ac's with those other machines, it means it has gone beyond 3.5kva

Pls i want to install a solar inverter system in my home that can power 3tvs+2decoders, 1fridge or freezer , 3fans and 8 energy bulbs through the night say at least 12hrs.

What unit of inverter, batteries and solar panels will be sufficient for this set-up and cost+installation.

If you remove, freezer from the equation, i will send you a quote for 2kva system.
If you are interested in the quote, drop your email address and i will send it

olawale100:
Kindly send quote for 1.5Kva and 3.5Kva.

Please, I will also need a quote to convert an existing inverter charged by PHCN to fully run on Solar.

HOW many KVA is your Inverter?

ifyan:
Hey Charpell.

I love your information. Keep it up.

Thanks

EgunMogaji:
I'll be doing a full standalone system for a 2 bedroom apartment.

I intend to store the batteries indoors, is there a safety issue?

Batteries are always safe. However ensure there is adequate ventilation around the environment your battery will stay

sorry from portharcourt.

Hello the cost analysis for 1.2kva, 2kva and 3.5kva are free. Anything exceeding 3.5kva means we have to come your facility to take accurate measurement and carry out proper Energy Audit.

In my village there hasn't been PHCN light ; we now use solar ; inverter and generator.

Good, solar energy will take over in coming years
