A quick wade into your scenario,

your AC - use only with grid power

your freezer - 270W x 6 hrs = 1,620Wh [ day time]

your fridge - 180W x 6 hrs = 1,080Wh [ day time]

only one TV at a time - 120W x 8 hrs =960Wh [ 360Wh/day time & 600Wh/night]

OX FAN replaced by 20W Dc fans x 2 pieces ........ 40W x 18hr = 720Wh [240Wh/day time & 480Wh night]

your laptop - 70W x 6hrs = 420Whr

light and phone charging 7 hours - 70W x 7Wh = 490Whr

night usage = 1,990Whr

Inverter size & battery - 1.5KVA 24V 200Ah

solar panel size - 2400Wp of PV panels

if you work within this sphere of calculations and with grid power supply, you can have 247 power supply & also your fridge and freezer are governed by a timer plug/switch

Found this thread via Google. I need a solar system in my house.

I wonder how much it will cost me to get a solar system that will power 1. One 2 hp AC, a deep freezer, one fridge, three TVs, one ox fan, one laptop for at least 16 hours per day.

I have a budget of 750k will this suffice? And with solar do I still need to charge it with nepa or generator? I need a quick answer.

Good evening @ GeorgeD1 & Bigrovar

I couldn't quote the lengthy message

Many of the arguments made earlier are true, I have had so many discussion with my roofers friends and people with homes or looking to build their homes that having a flat roof is best in case you plan solar to be used in the future but their response has always been in line of "send down the rain" roof types will always keep the inside of a house cool in hot days.

While their is always a win-lose situation to life ... Going with gives more win is a win-win in my book especially when ot comes to flat roofs.

Like a an esteem member here planned for such a scenario like this and his enjoying his setup.

A quick insight to your project

To lay it bare, your appliances are not efficient even if you try to manage it, they won't help at the long run & a quote will look bogus for these little setup

Proffered solutions, if possible when choosing to go solar

1. If a 12V TV with adapter can be used ... It will be a great alternative

2. Forget the fridge use it only with Grid supply

3. Use only TV speaker, forget the speaker too

4. Don't have idea of the bulbs but since it is a room, changing them to 5 or 3 watts and using only two at a go will go a long way to minimize yoir setup

5. If you can get them DC fan of 30W max. That will be good for your setup

6. Say your neighbor have 3 lamps to charge i.e. 9W x 3 and phone charging say 12W x 4 phones. That's 18W + 48W =66W for say three(3) hour period - 198Wh
( when you decide to go solar then only a device per person is best allowed) else your battery go hear am.

Conclusion

With a TV - 60W+ bulbs 10W+ decoder 20W + fan 30W = 120W for 5 hours is a 50% Dod for 100Ah battery

So a 1kva 200Ah Solar system with these new aforementioned suggestions, & your 10 hours of GRID supply should keep your going for 24 hours of power with no interruption. (Your neighbor charging wasn't included)

hooryo:
.
TV 145w
Fridge 90w
Speaker 60w
I have 4 bulb
Not sure of my fan’s watt rating..
And also my neighbors use to charge at my side.

As a contribution to the ongoing solar panel energy production debate, which many with monitoring system can attest to is.

For us a rule of thumb,

1. Tier 2 panels are calculated with 0.55% of nameplate or total PV capacity for period of 4 Hours.

2. Tier 1 panels are calculated with 0.65% of nameplate pr total PV capacity for period of 4 Hours


If the system is loaded I.e. energy storage and loads then it is expected to see energy production in line with above.

This proven true by remote monitoring.

Conditions based on a normal sunny day

I see your angle now and I totally support the idea.
Prepaid meter is the way to go

rottennaija:
The communities have zero to no power because discos are not expanding. Discos cannot expand because they don't have the money to, discos cannot even provide the meters to generate the money to expand. The FG should just change their policies. If you check well, discos sell single phase meters at 63k but this meters actually should cost 14k. Sohow many people can afford 63k? But millions can get a 14k meters (or 20k for the gprs meters).

I can confidently tell you that if NERC allows meters to be imported into the country, the price ranges between 14-16k, many people wil buy these meters, install them, estimated billings which people are not happy to pay stops. The discos will see the money to expand, the rural communities will see the energy as they pay what they consume.

You've made very valid points, but it's important to note that even with meters some community have zero to little power in weeks because of abysmal grid supply for such solar minigrid is the way to go.

But this is Naija you've got to know someone high up to meet with the job criteria

rottennaija:
These are wrong interventions and maybe they don't have the right idea. The FG needs to provide the interventions in metering. They need allow gprs smart prepared meters into the market by allowing imports of these. If the market is saturated with energy meters and consumers can get them off the shelf, the price will come down and the discos will see money to expand their capacity. The whole value chain in the energy sector benefits.

While this is good, means to which small to large business can benefit it to work on their model to help underserving communities is left out.

What help would a fund you hear about but cant apply for do for an average solar company owner with no big and deep ppcket to lobby it. Sigh! Naija

@ajabani4allah & @dollarnaira

A quick contribution to your conversation

LiFePO4 @ nominal voltage is @3.2V while fully charge at 3.6V - so a 3s/4s is 9.6V/12.8V charging to full voltage will be 10.8V/14.4V

While Li-ion @ nominal is 3.7V while fully charged is 4.2V - so a 3s is 11.1V charging to full voltage is 12.6V

LiFePO4 is closely related to Lb based batteries when been used with conventional inverters

What makes it thick to weigh this much?

Valto:

We also sell them too at a fair price through our partnership with the main distributors locally.

About the price, you will have to be specific I.e. knowing information like
* Depth of well
* Water level in well
* Height you looking to pump water to et. Cetera will be a factor to suggest which will work for you ...

Head roo

Keemie:
Where can I get it what's the price.

1. Grunfos Solar Pump

2. Leo Solar Pump

these two piece of pump have proven to work in the field and still going strong

in case when you are in need of the pumps, kindly reach for the best prices and information.

Keemie:
Can you please suggest a good solar submersible pump.

1. If Stab is before inverter input then it is fine as it will ensure that the you get a stabilized voltage even when Vs is lower than expected

2. Using a 30A charge controller is more appropriate for your system

3. if you cycle the pictures your charge controller is showing kindly collage them for all to advise more

micynute94:
*** Does using a Stabilizer (2KVA) with an inverter has any negative effect on the inverter (600W PSW).

I had my inverter set up last year around March.

Set up include: Full River 12v 160Ah FAT battery from Ojota, 3x150W Solar Panels, 20A charger, and 600W PSW inverter.

Recently I noticed my battery drain too fast.

Without sun, a load of 100W could deplete my battery from a full charge (around 12.8V) to 11V in about 3 hours.

Is it high time I changed the battery?

I usually don't use it below 50% DoD.

Please feel free to ask for more details I might opted out. Thank you.

Possibly tracks of fraud being covered. Such a calibre of school should have a fire hydrant on each floor to help prevent such properties & information lost.

Anyone here experiencing smile network disconnecting every 5 minute?but is frustrating that online activities or video svcks

He was generous to set me up with a dedicated free configuration file for my swift network that works with only one device, fair unthrottled speed when downloading 3-4 MB/s and truly unlimited

Enough for 720p movies, no buffering streaming via my Cocotv app

Alienwarfare:
Has anyone tried this guy?

I noticed a comm. cable from the inverter to battery, did it work?

are you having problem connecting via wifi or gprs model?

myrax7:
I need contact of a trusted solar panel, battery and charge controller supplier.

.

Victron is one of the good world known brand that delivers but with victron you simply need to match ot with top notch equipment too, which can quickly make project cost to rise

Their are other options like DEYE inverter, axpert, voltronic, phocos Hybrid inverter that's offers close to victron functionality like remote monitoring and more

Solar panels like Canadian solar, Yingli, ERA, Jinko, JA and more that guarantees energy harvest that satisfy his energy needs

Lithium battery are fast becoming a trend in RE & Since moni no be problem then brands like LG CHEM , pylontech, BYD and more that will ensure that he gets enough ROI on his install

In summary: To better decide what's best for him getting a reputable company to give a comparison quote between victron a standalone system & an Hybrid Inverter then the choice is let to your contact.

If you need more clarification, kindly reach out via contact on signature.

codeME:
hello Gurus,
Someone need very good setup, with the most reliable batteries and panels, what are the best options for the person, someone spoke about Victron! please let me know so i can inform him, he said he prefer a standard supplier with an office. i am sure finance may not be an issue with him. Thanks.

After carefully gone through your post, I noticed that you are just about having power and durability & not other key features - i could be wrong but the advantage of getting a good hybrid is getting more interesting daily when compare with standalone

I don't understand your comment about surge, it is not so clear, experience with axpert-Voltronic & Growatt neither of this inverters have had it's inverting side broken before ..... Even when one was struck by lightning.

1.The most common problems noticed with Growatt is the charge controller breaking down in few cases or fan stop working - fix for TL inverter blow away dust regularly

2. Some reports have it that mosfets get blown and maybe board replacement due to
I. Surge from lightning - fix install genuine SPD
II. Over load of inverter - fix carefully size your breaker not to your inverter size but rather load size

Thunderbolt:
Read a little about the advantages and disadvantages of TL inverters. What stood out for me was talk of being more susceptible to surge issues.

For those who have experience with these inverters, pls what are the practical issues I could face using a hybrid, and how could I mitigate against these issues?

Thanks

Good morning Sir,

I didn't see your message on time, presently the available slot is full but if any thing change I will ne in touch

Have a Great day ahead.

Kindly check through your post, maybe a typographic error

Dam5reey:
Since you have the wiring diagram and all the accessories, Simply wire accordingly, AC input and Output must be connected together batteries must be connected to same bank.

Do all this before switching on the Power on the inverter.

Any port Harcourt based pro solar installer in the forum to please kindly reach out to me via contact on sign.

Adverse effects, NO!
But most conventional inverter overwrites the charger controller as they charge with higher voltage making your solar idle during sunny hours

Michaelondon53:
Good morning all!

I want to know if there are any adverse effects if you charge an inverter with nepa and solar simultaneously.

My scope might be limited here as your choice isn't fully known but

1. If your fans can be changed to DC fans, then this is a game changer (30W max)

2. The prices listed here are not 100% realistic with current market prices except you plan on buying used equipment

3. Based educative guess that you might not use grid supply (Laptop -140W, fans -30W, lights -20W) A ceepro or 1000W - 500W pure some wave without charger should be okay

4. If you plan a 450W panel (150W x3) with a 100Ah battery, 30A PWM & inverter as aforementioned

Your battery and your loads will both be happy as your loads will be more reliant on solar rather than battery

5. This will cost more than your present budget except you plan and make things modular then make do with your budget and upgrade later

JC2021:
for just 2 laptops, 2 standing fans and lightings.

1. Solar panel (150w mono) for 30k

2. 2 -in-1 Pure Sine Wave Inverter. ( Solar charger / controller + 800va - 500w inverter) for 38k

3: For the battery, I have GBM 180va/12v in mind, but some people objected it. I will appreciate suggestions on good, long lasting battery (around 180va/12v) for between 70k to 100k

Total budget: 150,000 - 160, 000 naira.

it appears that your panels might be developing hot spot or de lamination from the picture provided

OkoroPeugeot:
So I got the panel down and this is how one looks a bit burnt.

The voltage is now going up though, 66v now, 90w.

I'd let it run till evening and see.

Sometimes the little things we do goes a long way
