yeah, the inverter actually have a 75amps adjustable smart charger. but i left it at just 25amps for now. i just set up everything yesterday, reviews will come later. the inverter can be wall mounted and is very intelligent. very programable.

Guy, u vex gaan o!

I use similar controller but 40A, the performance will suprise you!

How much did u get ur batteries

Valto:
i have finally a done a full upgrade. i now av a
3000watts 24v pure sine wave inverter
2pcs 200amps battery
30A EPsolar tracer A series MPPT solar charge controller
2pcs 200watts mono solar panel
my 30A PWM solar charger controller and 30amps battery charger is up for sale,cos my new inverter av 70A fast charger.

Congrats bro, no be small upgrade ooo.

kindly give a review of ur EPsolar tracer A mppt and comparism with pmw.

I guess 70A for 2 200AH batteries is a bit high, would advice you adjust d charging rate if possible or use solar for charging pending u add more batteries.

Cheers

This is very nice and inspiring.

Very much interested bro, gud wok!

agentakins:
Please bros, I am interested in this your programmable timer switch and I searched on aliexpress to buy one but I saw different types which I don't know which type to buy. Can you kindly upload the picture of the type you are using? Thank you.

Am presently not @ home.

But you can buy any1 affordable. Just make sure you specify UK plug

mrhello:
Can a modified sine do same? And what's d exclusive diff between what a pure sine and modify can do?

Thnks for your response.
1. If I hv followed u well, does it mean it's dis 26A inbuilt charger dst has bn charging your 4 x 200ah?

2. So can an average 20A or 30A external charger efficiently and conveniently do d same for 3 to 4 pcs of 200ah battery?

3. Any short or long run side effects of charging 1 x 200ah battery wt a 40A ext charger?

4. Are there any advantages of each of these over d other and which would u always recommend?
. Inverter wt charger inbuilt
. Inverter wt ext charger

Abeg, no vex o!

1. My solar panels does 90% of the charging and i kinda prefer slow charging cuz it makes ur batteries healthier.

2. It can, it depends on ur depth of discharge (DOD). i hardly discharge my batteries to 50%

3.For me, 40A charging is high for a 200AH battery

4. It all depends on d efficiency. 30A charger either inbuilt or seperate will produce dsame power only if its of a true rating.

Vex kee?, me sef dey learn on this thread!

Cheers

mrhello:
Thanks for sharing broda man.

Though I know your inverter is pure sine, can a pumping machine run well on modified sine too? And what's d average watt of a 1hp sumo?

And what's d idea of d programmable timer switch? Thanks

Sure it will, its only d humming sound of modified sine wave on inductive loads. but dats not an issue as far as am concerned.

1hp = 746watts

Programmable switch is just a timer plug. You can set the time it switches on and off, also you can programme up to a week.

mrhello:
1. Hw did u wire d load? As in did feed all these loads into your inverter or some to it and others to other source?

2. Hw do u manage this timing, 10am-12pm, etc? Do u do it manually by putting on and off d concern load as at when due or u auto prog them or the inverter sorts them as at when due? Pls explain this better.

3. Going by your time routine, does it mean there's no day d 2 freezers and d fridge will run continuously all thru d day, as an average nigerian does when on nepa utility?

4. If nobody is home as at when to power on/off a given load, what then happens?

No vex o. Just want to learn and also for others to benefit.

1.All d housing wiring is on d inverter except AC outlets and cooker

2 & 4.I use a programable timmer switch for my appliaces. so u can programme specific timing for your devices. u can easily buy on aliexpress or Amazon

3.If we are @ home especially weekends, we power randomly based on priorities. washing machine, pumping machine, ironing etc

The most important thing is to know your appliance rating and best time to utilise them

Cheers!

mrhello:
Is it wt imbuilt charger or u use ext. charger wt it or purely solar charging? If ext. charger, what brand and amp?

Can we hv d pictures of d inverter, esp front and back?

Its with inbuilt charger. with 3 stage charging max @ 26A

Am presently not @ home but its housed in a cpu casing with its display @ d front

OCTAVO:
Waiting...

OCTAVO!!!...longtime bro

ibro360:
please sir what's the brand of your inverter and how many volt is it tnx

I build my own inverters cuz i don't trust the ones in market

The very good ones are over priced and the cheap ones are of low quality!

I have a 'true' 2000watt 24v nominal voltage and i can power anything in house

Valto:
wow, how much did u buy ur mppt40A can u link me where i get an affordable 30A.

There are different products in market now...
You can get Epsolar Tracer A series 40A(4210A) around 65k and 30A (3210A) around 50k.

Valto:
if u buy Ipower 3KVA inverter of 82k, it comes with 60A PWM solar charge controller inbuilt. so 4pcs 200amps battery @70k each should be 280k, then 4pcs 250watts solar panels @50k each should be 200k. total is 562k. u should be budgeting 580k

I would suggest u get an inverter and seperate mppt controller.

And u can even reduce cost if u have average of 6hrs sunshine (depending on your location) and don't have very serious loads to power apart from freezers.

I have 6pcs 130w using 3*3 connection with a 40A mppt charge controller and battery bank of 4pcs 200AH.

I power 2 freezers (btw 12pm - 4pm)and a frigde (10am - 12pm) use a 1hp pumping machine somtimes in the aftn. Power my tv, home theatre, dstv, lightings, fans in d evening and i hardly drain my battery bank to 50%"DOD in d morning.

I have decided to go offgrid for a while. When using solar, you will undstand power management more!

Cheers

Valto:
kind of different setup. i will use the same inverter. my brand new battery is being used with solar and charged also with 30amps smart charger, but the fairly used battery i will buy will be used solely as back up, i.e only when the new battery runs down. which of the 3 batteries do u suggest i choose?

Instead of buying another fairly used battery, i would advice u invest in your solar setup.

Try get more panels and maximise ur usage during d day. You can still add another new battery not later than 6 months time so you can start saving.

By d time u hv more panels, change ur controller to MPPT and enjoy solar array in VIP mode

keep it up bro!

@rajo4real,coderXO et al

Thanks for your attention.

The Solar panel came in a pack of 2 labeled 130 watts (so two packs=4 pieces).

It was assembled last week Thurs and Unfortunately I don't have light for the past one week so have not charged with Nepa. I only tried charging with Gen once for 2hrs but charge controller still displayed 25.5 volts.

I honestly don't know if my panels are facing west or south.

I am based along Lagos-ibadan Express way after Berger.

I also discovered my solar panel charges my battery at 1.4 A so armed with your analysis I have confidently called the installer to come check panel positions again. I was scared the fault was mine initially.

Thanks so much for your contributions and will probably get a MMPT charge controller now.

Thanks everybody once again!


N.b: attached is a picture of my Solar Panel right now. Is this the right position please?

From your pix, your panels are facing slightly off east (ur DSTV position) and this is extremely wrong. Sun rises in the east and sets in the west.
Check where the sun rises early in the morning and ensure your panels are tilted towards the opposite direction. With that you will be able to capture sun power till around 4pm - 5pm

Because your panels are only working between 7am - 11am. Its better you face south or tilt towards west, you will have better yeild.

Don't get discouraged bro, you can still manage the PWM till u get an MPPT.

Cheers

zanyzara:
I have 4 solar panels, (each coming in pairs of 130 watts).

Will pleeeaaase await your opinions. Thanks!

it seems your panels are not charging d battery effectively.

do u mean 4 pieces of 130watt?

pls give a better explanation on how ur panels r connected.

positioning of ur panel is also important, is it affected by shading? are u facing south or west?, r ur panels tilted and hope they r not covered wit dust?

hv u tried charging wit Nepa? hv u used a meter to measure individual battery voltage?

which part of the country r u located? and ur controller is pwm which might not give u more than 60% of your solar array output; mppt is much preferable.

Pls try give more info so that others can contribute aswell.

Im2Busy2Bother:
The things I've seen, I know a guy that connected up to 1KW of solar panels directly to four 200AH battery. He doesn't use a charge controller, which by the way is the acceptable practice, but surpringly he has been using it like this for 2 years plus!


At the moment he is completely off grid, he had disagreement with NEPA and told them to come and collect their wire

well, am not disputing that but he might be killing his batteries gradually.

Factors like location, positioning and configuration of panels etc might be favouring him presently.

I bet he would not try this in areas like sokoto with proper positioning of his solar array!

Valto:
lolz, even one supplier told me to just connect directly and start using. i refused, after reading the voltage with meter. i cant afford to damage my 200amp battery i bought 70k in this hard time. 30amps solar charge controller is on the way.

Laposta is very correct, pls use a charge controller.

And make sure your controller is connected to battery first, then your solar to controller.

cheers

timifakay:
All components are brand new, bought at Oke Padre, Ibadan. Battery seller says it has warrantee, even uses same in his shop inverter set up.

Nah so oh, be like say I go take ham start business if person want make I help with the installation.

Kindly give more details about seller.

Thanks

Valto:
my 200watts solar panels arrived today. already installed. am waiting for the solar charge controller to arive tomorrow. i used a normal meter to read the voltage and it shows 40volt, solar users in the house it that correct?

yeah, its correct. datz ur open circuit voltage (Voc)

pls snap d details on ur panel so i can give better explanation.

Welcome to d solar world!

TheTransformer:
Hello CeeJay80s, is it possible to connect three 100 watts solar panel 12 v to charge a 200ah battery with a 30A solar charge controller?

Yes you can, as long u r using an MPPT controller, u can play around with series or parallel connection.

ceejay80s:
My guy ,lagos hot pass Sahara desert , if u hang ur solar panel for lag , ur battery go charge full in 3 seconds

lol.... but truely solar is d way. might be a bit expensive but will give u independence and peace of mind.

My solar installation starts charging as early as 8am in ilorin... i no send PHCN anymore ooo!

ceejay80s:
My guy ,its a miracle from a saint, I dey jeje dey drink my garri, a saint from nairaland called me on phone and bought a brand new tear rubber in carton 12v 100ah deep cycle battery,
God has already blessed saint2ace , all I want from God is to bless him more, good people dey nairaland o, he is so gentle and kind enough to even drive to my area to deliver it to me as a gift,
SAINT2ACE, God bless and protect u and ur family forever, I will never stop praying for u,
Good people still on nairaland and saint2ace a real saint is one of them

Congrats Ceejay80s, u deserve more!

@Saint2ace, thanks a million!!!

spyglaxx:
yea 100 watt is enough.The mono is latest technology.It peaks at 19.45volts while poly is old technology and peaks @ 16.4volts. and you would need a charge controller. are you in lagos?

pls am in need of solar panels, @least 130watt each and charge controller. pls hw much is ur charge controller and can u share a pix?

thanks

Barezzi:
Geesampower will assist u with prices and config if u want...

Thanks Barezzi,

Thanks

martinz1:
Ok

Here r d pix...

martinz1:
New or used?

Fairly used but looks as good as new!

Good work Ceejay!

This dude is so humble and trustworthy, he helped me with some stuffs from Lagos.

The thread has actually serve as an eye opener for renewable energy source.

I also got a link for very reliable and cheap batteries (12V, 155AH) @ 25k each.

Will be posting pix soon....
