earthrealm:
thanks gents for the suggestions.
seems the dc pump is a better option. am wondering if anyone is running such, lemme tap from his experience.
2ndly is the pump easily available in nigeria? or aliexpress..hence the need to purchase 2 pumps, incase of 1 going bad

3rdly, can i hook it up directly to the solar panel, without battery?

4thly, if answer to 3 is yes, i am considering retaining the old inverter setup, however the output from the panels will be split into 2, one going to sumo...the other going to the CC of the existing setup

i wish to automate the whole system, with auto flow shut off, so the system will be independent of human input, as setup is in the village. a regulator will be installed in the tank to cut off power...when tank is full...and also activate power when the water gets to a certain level.


the water demand is minimal, say 200 liters daily, so a 2k liters tank shud last 1wk or so. borehole depth is btw 80ft to 130ft. most pumps are rated flow/hr like 2000ltrs/hr...or 30L/minute , can i simply divide by 24hrs to calc the hourly flow rate....abi the pump is designed to work 24/7??

I have a solar pump/borehole on my farm.

The pump is a submersible which I bought from China and it hooks directly to the solar panel. The pump has it's own MPPT controller. It is a 1,000watts pump, hooked to 6x 300w panels. It pumps around 18,000 litres on a daily basis cos my guys put on the pump once the sun is up and it doesn't stop pumping until the sun is down.

Total cost was around N650,000.

I reckon if you need a smaller unit, you might be able to design one for around N550,000. You'll put it on for about 3-4 hours daily and you're good.

kio052001:
please guys, when is it best to use a PWM or MPPT charge controller

MPPT controllers are always a better fit except when cost is a significant deal breaker as they're more expensive. In simpler terms, there are no instances where PWM is better except you cannot afford MPPT.

Can this work for a 12v system?

You'll need a MPPT CC for it to be effective. If you want to use PWM, you have to be certain it can accept a PV of up to 45volts which is the PV of the solar panel.

hello house, being a while. need some inputs on this.
I currently have a system that works well for me.
2pcs of 100ah batteries in parallel.
40a pwm cc, 1000w modified 12v inverter and a 600w pv (150x4) in parallel.
inverter runtime is from 7am to 9:30 pm daily with average load of 80w. from 9:30pm to 7am, I run dc loads of about 80w load.
am able to achieve. above 50% dod with this setup. I am now upgrading as I need am adding a 80w AKIA fridge to the setup. the fridge will run during peak sunlight around 11am to 3am.
I would still love working with a 12v inverter because of my Dc loads.
whats your take on the required upgrade.@ceaser,topmost,kiekie,..niyi....ojesky....etal

I've got a few units of EPEVER 30A MMPT Charge Controller for N35,000 if you'd like an upgrade of your charge controller. It is also available on my store on Jumia if you'd prefer to deal through Jumia.

earthrealm:


Load is battery, not inverter?.
Where does the cc output go to?

Sorry for the mix up.

By solar panel, I meant CC. So output from the CC is the DC Input on the Wattmeter. I've edited the post to reflect my thoughts correctly.

Load is the battery, not the inverter. It is the battery that is drawing load from the panels, not the inverter.

earthrealm:


oh, sweet, the mpp solar tracks energy usage again?..thats a big plus. saves one the small coins and labour in installing a standalone energy tracker as well. reminds me, that am yet to install the AC & DC UNITS I BOUGHT.

Anybody using this unit?...dc watt meter
Could you explain how you connected your cc and inverter to it

I use a similar meter.

The DC IN is your solar panel output from the Charge Controller. The load is your battery.

So the bottom terminal (as placed in the diagram in your post) goes into both the positive of your battery and the positive of your terminal. The second hole goes into the negative side of your panel and one side of your shunt. The third hole goes into the same side of your shunt. Finally, the fourth hole goes to the other side of the shunt and the negative side of your battery.

I hope this helps!

If you're looking to buy small MPPT CCs...20A, 30A, etc. I'm your plug. Check it out on Jumia.

Just go to Jumia homepage and paste the extension below at the end of the jumia web address. Quote this message if you have any issues locating it.

Please don't do this. You will short out those batteries and you're at the risk of causing fire.

On top, you have a series connection with one cable running from +ve of one battery to -ve of the other battery and then on the charging side, you're connecting in parallel, +ve to +ve, -ve to _ve. You're essentially connecting the two terminals on one battery together!

Best bet is to match your charging and discharging voltage setup 12v/12v or 24v/24v. You can't do 12v/24v except you have a manual shut of so that the two cycles aren't operational at the same time which is very stressful to achieve.

microgiant:


The sketch is for regular batteries, which i already know from reading this thread.

Please, see sketch attached, as you are aware the LiFePo4 brand has discharge and charge lines separate discharge lines are in series, giving 24V which is clear to me.

My question is should i connect the charging lines to the PWM CC parallel as in my sketch or I also have to connect them in series like the discharge lines.

Note the batteries comes with separate lines unlike regular batteries with only one for charging and discharging.

Thanks for your response.

Penuelseun:
Just buy two or three tokunbo laptop chargers(depending on the capacity you want with the same voltage and current rating, and a pwm charge controller(30a works very well) , it works perfectly. Just add a diode in each charger's output

Nice concept...However, this would only work for a 12v battery system.

It won't work for a 24v battery system as the output of most laptop chargers are less than 24v.

earthrealm:
While on this rechargeable fan issue.
The batt in mine crapped out.scoured the market..no luck.
Saw on AliExpress..but price is high and shipping another wahala.
This is a lithium battery, so does it imply that the fan has an internal bms??.
Am guess 3 cells in series..and probably 1 or 2 has died.the fan rarely worked up to 2hrs when fully charged....unlike it's lead acid brothers

Who can help me get a replacement??

I can help you with a replacement.

I installed a 20,000 litre solar borehole for my farm in January. So far, so good!

Except you're using the boreholes commercially, the cost of a solar borehole is prohibitive, I should add.

ojtech8291:
500L per day should be okay

From my little experience, each pack in series puts out the total current draw and a fraction of the voltage. This means that the each 1s80p you have will put out 3.7v (nominal) and 60A (BMS capacity) and the 14s will put out 14x3.7v, 60A.

Your small wires are still good though as each cell will put out 60A/80cells which is less than 1A.

totalgreen01:


1. I see ur point, but in this se0tup it's not required cause I am passing thru 60A BMS, for 14s each will do a max of 4.2amps which is fine for such tiny cables..... I ran my A/C last night the cable was not even warm

2. will do, just running a test last night thanks for the observation

3. I do have a spot welder, and I have been welding for a while now, only on very small packs... u should NOT do spot welding on such large packs, in fact NEVER spot weld your large packs, for Li-Ion if one cell goes bad(short-circuit ) then like me you will kill all 80cells in the pack, I had to fuse all the cells, but another option is to spot-weld the fuse which is too tedious for an old eye like mine

thanks, I do appreciate your suggestions and observations

Background info: When using PWM controllers, always connect your panels in parallel

However, it is not advisable to use PWM controller for 300watts panel if you're bringing down to 12v. The VOC of a 300w panel is 45v (36volts when under load). The max. current output is around 6A. The 12v PWM controller will bring it down to 15v, 6A which is about 90watts and you'll lose the rest.

I'll advise you buy a 30A MPPT controller, that way you can connect a max of three 300w solar panels in series and another four panels in parallel, making a total of 12 panels.

I can help you facilitate a MPPT controller than won't break your pocket from China. 100% money back guarantee

tchijioke:
Good afternoon gurus...i need clarification on this:- What is the Max pieces of 12v , 300watt solar panels that can be connected to a PWM solar charge controller (12v) Rated :
Current: 50A
Max solar voltage: 38VDC?.
Thanks in anticipation of a timely response.

What is the size of PSW you're looking at?

zeanslim:
hello, I need 1kv+ APC UPS without battery the 12v pure sine wave version, or cheap pure sine wave inverter.

I'm planing to build an inverter on budget using 18650 li ion battery cells which I have began assembling.

I stay in Lagos if anybody have for sale.

Here is my two kobo...

Do not power your freezer with your batteries. Even if you have a sizeable battery bank, you'll run down it's life because of the frequency of charge and discharge because a freezer is on nearly all the time.

Buy a few more solar panels and run your freezer when the sun is up only. I'm guessing you'll be able to run your freezer between 8am and 3pm with the right size of panels and the panels will still be able to juice up your batteries.

I have a deep freezer that consumes 200watts and I have 2x 200 watts panels. I reckon if I wanted to put my freezer on it, i'll need two extra 200 watts panels. The cost outlay will be much cheaper than buying a few more batteries.

Alejobs:




I discover this too a while ago.... So I use a 2000watt inverter for heavy duty load, such as ironing, pumping water and occasionally with the freezer but my 24/7 load like TV, light and fan. I discover this by accident cos my big inverter was acting up and battery was weak then .... If I put on the inverter then with no other load on...... Battery on 12.7 will drop to 12.5 instantly..... I come see say the small inverter no dey leave 12.7 until I plug load......



My challenge now is powering my freezer.... It runs down my 2 battery fast

Intellab:

See image below

For this price, it certainly is a Modified Sine Wave inverter. A pure sine wave inverter of similar model will be at least $150.

Intellab:
I saw this on aliexpress.
Is it pure sine wave?

It is the price on offer that will tell you whether it is Pure Sine Wave or Modified Sine Wave. How much was it selling for?

I have a similar shaped product from China. It is Purse Sine Wave.

zekepio:
I have a 150watts solar panel
30a Charge controller
100ah battery
650va blue gate ups

I tried using the above setup to power my 1.5hp water pump but the ups trips off when I connect the water pump.
I'm guessing the capacity of the water pump is more than the UPS can take.
Do you suggest I change the UPS or forego my desire of power the water pump with the solar setup.
I need the water pump on for 4 hours daily.

Your system is grossly inadequate for your water pump.

1.5hp = 1,120 watts. However, pumps are powered by motors and they need at least 2.5x the running current to start it.

Hence, your minimum inverter capacity should be 2500watts pure sine wave. I would have said 3000watts but inverters have a temporary overload function, some as much as 2x the rate capacity. So a 2500watts inverter should be able to support up to 5000watts for a few seconds which is enough to start the pump.

You will need solar panels of 1800watts minimum because your panels will hardly put out maximum power even during the hottest times of the day.

You will need minimal size battery, say 200ah, to be like a temporary reservior for those times when the sun is hidden by the cloud and power output from your panels drop below 1200watts.

Except you're using this pump for commercial purposes, I'll suggest you stick with using generator for it because the solar set up cost will be expensive!

I bought d suoer battery charger it did not last up to 2mnths,I bought d suoer inverter it packed up b/c I erroneously reverse d wire polarity I think such device shld have reversed polarity protection,fuse & transformer.

For the inverter, it is the fuse that cuts when you reverse polarity. Open it up and look for the fuse, then check to see if it is burnt. If you can't identify it, snap the panel (front and back) and post here. I should be able to assist in identifying it.

Hello Laposta.
You were informed that the refund would be initiated on the 25th of July and not on the 24th of July.
Please, kindly check your bank account for the money.

Thank you.
~HC

Refund received.

Thank you.

Guys...

I have waited long enough to close this transaction and I'm growing impatient by the day. You promised to initiate a refund on the 24th of July. Today is 26th and I haven't still received my refund.

Please, send me my money so I can make use of it for other things. Thank you.

Hello,

I have sent numerous messages to you on Whatsapp asking for an update on my package without response. My goods have been held up for more than four weeks now and your last excuse given was that Customs were on strike.

Customs have since resumed clearing and I am yet to get a concise feedback on my goods. I have sent numerous messages to you on Whatsapp and you guys have stopped talking to me after promising that you will call me on Friday without fruition.

I need this addressed ASAP before I cross my threshold of patience.

Regards,
Laposta

Hmmm...thank God you said Deep freezers. Their compressors are quite resistant to surges. Let them use it on LCD televisions that don't have AV protection and let's hear their story.

Not that I am totally condemning msv inverters but it is better to be safe than sorry bro.

Boss, easy on your self. I have been using a souer MSW inverter for over two years and I've been powering my LCD television with it since then without any issues whatsoever.

MSW inverters work well with most domestic appliances except Ox fans (and the likes). Your phone or lapotop chargers may also get hotter than usual but that is all that is. It won't damage the devices.

My MSW inverter hasn't damaged anything since I've started using it...

We all know that yahoo yahoo is bad. It’s taking money from hard working people and destroying their lives,giving them emotional breakdowns.

But we have to look at it from another angle, I’m not in support of Yahoo, neither am I against it. I’m not against it because the Government has failed us the masses.

Yahoo is a way of liberating oneself from the shackles of poverty. I know several yahooboys that are employers of labor today. I know several yahooboys that are the breadwinner of their family.

I’m against yahooboys that scams locally, scamming your fellow Nigerians, I’m totally against that. If you must scam, scam the white folks.

I’m against yahooboys that goes to club and squanders thousands and millions of naira on drinks just to show that they’ve “arrived”. It doesn’t make any sense .

I know a yahooboy that owns several mobile phone outlets, several businesses, doesn’t attend night clubs and the night life is definitely not for him. He’s married with kids. This guy and several others relies on yahoo yahoo to survive .

If we scold yahooboys , let’s also remember the Nigerian economy,unfavorable standard of living, made the boys do what they do today.

They’re the lesser devils , instead of kidnapping , murder and armed robbery, these boys chose to scam the white people.

If I’m to choose between an armed robber and a yahoo boy . I’ll gladly go for the lesser devil( yahoo yahoo).

He owns several mobile phone outlets and several businesses but uses yahoo yahoo to survive...

Why can't he survive on the businesses he now has? If he can't, then those businesses are just a smokescreen to deflect attention from what he truly does which is scamming. Such people won't even care if the business is making losses cos yahoo money is still flowing.
