Hey guys, I want to go totally off grid

But I guess it’s not all possible

Because in my current setup, PHCN light from the mains charges my inverter

But now, we have not had light in my area for over 24 hours

Does that mean once my inverter battery runs out, I’ll be in total blackout ? Since it’s the Nepa light that is charging the inverter

Is there anyway my installer can reconnect the setup in a way that the Solar panels charges the inverter too?

Thanks

Hmm... good morning sir

Please note that Inverters are not for storage of power, they only convert dc voltage or Battery voltage if you may to AC ( normal electricity if you may).


So once your battery is used up, that’s all, all required is a recharge.

It’s more like saying after your phone battery is used up, is there a way to charge the phone to make sure you have more backup time, no, you can only charge a phone battery not the phone in particular.

3 important things to consider when purchasing a battery!

Cost: most buyers are particular about the cheap battery brand, you see through experience, I have seen that there are some goods or commodities you don’t just approach due to cost reduction, it’s can be very costly on the long run when the battery you bargained for only lasted 6months and then it’s gone, then you either start buying a new Original one or find a fairly used battery on the long run, and when carefully considered we find out that the cost difference of an original battery and the one the buyers purchases is just 10-20 thousand Naira difference, and is supposed to last a good 3-5years. While you consider cost, also consider the performance of the cells, else you may spend unnecessarily

2. Track record: most batteries have track records, except some non popular batteries (they may be strong) but without a track record, from other customers, when I say track record I mean customer feedback performance report, it can either be assured by a trusted installer or a seller with some convincing proofs
3. Warranty Integrity terms: don’t be too quick to pay without first agreeing with the seller on the warranty terms, and also in the aim to trust the warranty claims, be particular about the timing, of per adventure battery fails within warranty period, seller should be ready to pick the batteries up for repair or replacement. Getting a signed document is a good practice for both parties. ( when you treat your buying in a quark manner, expecting a professional performance is just a daydream.)

Explain this reverse polarity pls. Fan port says 12-15v in. So I guess it will take my 12v panels. If 7ah battery serves me overnight, 40ah should serve 3 fans(7ah×3=21ah)overnight and leave for day use when/if necessary.
I am still weighing my options and seeking opinions.

simply dont put the red or positive cable for the black or negative cable, that's what polarity in this case means

The funny part is someone who's a bit impatience may end up reading this last few pages and thus end up setting himself up for failure. It's even more disheartening when the misconception is from the so call solar experts and installers

The most important thing is, understanding how this things are calculated, With both theoretical and practical proven records.

This should not be of any misconception because, seeing a misleading information to an “innocent” Person asking a simple question, it won’t be okay anyone let it slide, and at the end of it the clients over spends and left unsatisfied.

Topmost11:
Your fan is non rechargeable dc fan. But for my fan, Is the direct DC via the DC port or battery terminals?

Ensure your solar panel dc voltage is same range with the required input voltage of the fan.

So ensure you connect without mistake ( reverse polarity) that’s when you are connecting to the fan dc port, the fan it’s self as a dc cc to charge the battery, if you connect the panel to the battery directly you will risk over charging the battery.

Ensure the panel is same dc range for the fan.

Misconceptions everywhere..

gtech2sure:
Let me quickly brief you on this. I am not an installer though but a fresh graduate who understand basic Electronics, Electrical and Computer Engineering all together. I had solved solar system problems for few installers who got lost for proper choice of components used and calculations. This calculations pretty work well


I am going to show you simple calculation to know like how many solar panel you need, watt of inverter to use, battery, charge controller and time to get a full charge using calculation.


Mind you, the calculation aren't hard. We only need addition, subtraction, multiplication and division.

Now let's begin
Before i proceed, there are some calculations i will not include in order not to make everything complicate, the calculations are based on energy loss in solar inverter system. With the one i will drop here, you can become an installer overnight with the help of youtube for practical aspect.

This system will be designed in 24v


LOAD: 700 watt

INVETER:
Inverter should be greater 25% than the total Load


Therefore load = 700 watt


700 x (25/100) = 175
700 + 175 = 875 Watt
This is the rating of needed inverter. But go for 24V, 1000 watt inverter or higher


BATTERY:
To know the total battery that could power load of 700 watt for 8 hours, just mutiply total load with time.
ie 700w x 8 = 5600w
This shows you need battery that could generate 5600 watt of power for 8 hours.


Use this formula to convert AH of the battery to watts.


W = V x AH. where w= watts, v= battery voltage and AH = battery amps.


Therefore: 12v x 200ah = 2400watt


Mind you, the system design is 24v
Due to this, you are going to use six 12v, 200ah battery where the three steps battery will be connected in series while loop them together in parallel to give you 24v, 7200 watt.


I know you might be wondering that the watt of battery we got here is more than what we need, just don't worry it's an added advantage. Our 7200watt battery here could power load of 700w for 10 hours.


It's done in this way:
battery watt/load: 7200/700 = 10.2 hours


SOLAR PANEL
To get solar power rating to use and time to get your battery charged depends on choice but i recommend 6 hours charging time because of cost.


It goes this way
Time to charge: battery watt/time (hour)
= 7200/6 = 1200watt
Your battery will get full in 6 hours with solar panel of 1200wat.


Note: You must not put ON any load on the system for you to get full charged within the period of 6 hours. But if you can't abide with this, you have to budget extra 700 watts solar panel to your cost


VOLTAGE CONTROLLER OR REGULATOR:
Power rating of solar used to determines the power of regulator to use.


Note: That Regulator rating are usually in Amps which you would need to convert to watt.


The regulator can be gotten using this formula
A = Solar rating (watt) / Battery voltage
= 1200 watts / 24
= 50 Amp


Therefore, you need 50A, 24V charge controller.


In summary this is all you need
24,V 1000watt inverter
Six 12V, 200AH battery
1200watt solar panel
24V, 50amp charge controller.


Goodluck..

Thank you for the breakdown sir, but 6 200 ah battery?

That’s quite too much for the system required( even though nothing is too much when it comes to storing enough power)

When calculating back up time, please you simply

Know the load requirements

Which in this case is 700watts

Power = current x voltage
He needs
700watts = I x 12v battery
I= 58.333 amps

Battery capacity (he suggested is 200ah)

Ah/h ( amp hours divided by amps gives you hrs(or duration in hrs, because amps cancels amps and you are left with hrs)

200ah/58.33a = 3.4hrs

Now if we are to recommend a better back up capacity


700watts = I x 36 or 48v ( 4batteries 12v each)
I for 48 v = 14.6a

Since the 4 batteries are in series the ampere remains same

200ah/14.6a =13.6 hrs or roughly 13hrs 30minutes

For a 36v System the duration is lower than this.

I hope it’s a bit clearer

Please Can someone help me out

MaH?? you mean, I guess you meant “Ah”

Would you rather chat us up on whatsapp?

Ok but to run 8 hrs daily with 700 watts load, I don’t see
300 watts solar array getting you that
And again in case of no sunlight and per adventure your 200 ah battery is full, with 700watts Load you can only get abt 3hrs backup

Planing your power needs is the best step to take and avoid regret in solar arraying

www.jekitech.com

Buying a good charge controller!
Basic difference between an MPPT and a PWM
Is the mathematics of power conversion

For instance; When a 200 watts 36v panel sends power to a PWM Charge controller @ 24v
5amps this Charge controller will only pick 24v and 5amps and waste the remaining 12v (36-24v)

But for a good, I sound this again an Original and not just that they wrote MPPT on the body, but original MPPT, minimises power loss and MaXimize power.

It converts the remaining 12v to amps so the charger then charges at 24v about 8amps so, we have only minimal power loss

Hi Guys,

Any RELIABLE Panels/Inverter seller on here, without having to triple and quadruped checking anything. I am saying this because I have been sold fake/re-badged panels on here few years ago and the seller swore by everything but later admitted and put it down to their supplier's fault...Yeah right.

So any RELIABLE sellers please let me know.

thanks in advance.

You can contact www.jekitech.com or whatsapp on 08031138665, we sell and also install, with good track record

I for one think if you don’t plan a solar system to serve for low sunlight days or rainy seasons; you have not installed well.

In engineering planning you go for the worst case

A system that will serve you well is determined from the beginning of your installation.

Don’t be too quick to go with cheaper budget; most times clients regret it, because they ended up buying substandard products, from an hit and run seller or installer.

Especially Batteries

Be ready to hear the truth even though it hurts to know you have exceeded budget.

You were meant to make inquiry and understand the Load involved !!!

I put this to you, What is the Ideal set up for some who uses 2000Watts 24/7, you think he only need 3KW panels

You need comfortably
4-5 thousand watt solar panel array
16 nos of 200ah batteries

To secure 14hrs backup without sunlight

And the day hrs are covered

So 24/7 over covered

Dm me at my signature whatsapp no for the break down.

Thanks

As for the 14.6v thing, does it apply to all batteries? 'Cos some batteries have charge voltage of 14.4-15.0v or 14.3-14.7v written on them as the recommended.

That’s fine if it is stated that way, many people end up destroying thier batteries; having not to check those parameters well enough can on the long run damage the cells.

eleojo23:
Good morning guys.
Please can someone recommend a good external charger for 100-200ah batteries?

You can check Famicare; or one of these Ericsson chargers; am not a fan of cheap Souer chargers, Some charge up to about 14.6v, for a 12v battery and that is destructive for most Batteries in the long run

Juliana7:
@op, pls sir when there is rain althrough d day and no sun how do one charge d inverter with solar panel. Pls forgive my ignorance. Thanks

Good evening ma Juliana,

I think it’s ok to ask when we don’t have some enlightenment about a matter, and this is exactly what you have done; I celebrate you,

To your question; now depending on the solar power and it’s reception to light; solar panels need light to power on and charge batteries, as much as there is enough light from sun to still make us say this is day not night, solar panels generates power

But during rainy season, the solar panels will only produce lower power, since the light from the sun is low, so as much sunlight more power generation, low sunlight lower power generation.

When there is no sunlight at all then no power generation from your solar panels.


I hope this answered your question, and if not please clarify. Thanks

Jekitech; we love to be part of your Power Story

Thanks so much, I have informed the installer but he kept telling me different stories and arguing that the battery is good

Ohh, no problem, if you would, chat me up on my whatsapp no at my signature

abbeyforex:
I have a solar power system of 3KVA 12 volt inverter and 2 pieces 200AH battery. I use it to power only 1 chest freezer of 169 watt 1.2A but the issue is that the battery gets drained and drop to around 10.8 whenever the sun starts setting (around 4pm). I have a feeling the battery is not good or is this normal. The set up was done about 3 months ago and initially it last over the night till when the sun begins to rise but recently, the battery gets drained so fast. Pls advise

I think I get your point

This issue can be traced to your battery(probably are bad) or its that your Inverter as destroyed them; by consistent over discharging the battery, and in long term as destroyed the battery, a good Inverter should not discharge a battery below 10.5- 11v, so as not to use up the batteries to 0 level for a longer life span. Because once the sun goes down, your battery drops to about 10.8v, this may show you immediately that your battery cells could have been tampered with.

What to look out for
1. The battery (orginal?)
2. The solar charge controller( could it be that it’s overcharging the battery; which could I turn damage the cells)
3. The Inverter May have been using up the battery cells to 0point and in turn damaged the cells


I would advice you contact your installer; if you haven’t. But you could chat me up on whatsapp too ; let’s see how you can fix it. At my signature

earthrealm:
am looking for a budget install for borehole water supply.1k or 2k liters tank
am looking at 3 options. has anyone deployed any of the options listed , or has a superior option to recommend to me.

note: 2 x 250w panel , 850va luminous hybrid inverter, 12v 200ah quanta battery, 12/24v 100voc fangpusun 50aD mppt CC already exists in the house

option 1: get a dc sumo pump and power it directly from solar panels fitted with overflow regulator

option 2: get a normal 0.75hp or 0.5hp sumo pump, get 2 x 12v 200ah batts or equivalent LIPO4 and 4 to 6 units of 250w panels, with a 2kva or 2.4kva hybrid inverter with surge capability

option 3: get a battreyless inverter and connect the sumo in option 2 directly. 6 x 250w panels needed

Option 2 is your best bet; The sun variations is different; the presence of batteries in your is also to cover up for this variations, for instance the sunlight goes down, the battery then bridges the gap.
