Thanks Bro! I thought you've abandoned me!
You know I was into Hybrid system even before I got my first solar panel, so I just switched to hybrid setup for the time being. See instantaneous yield below.

abandoned keee

abandoned keee are always a busy person and I don't want to disturb at work, d hybrid setup is getting famous these days n it also save the stress of getting another cc, besides i like them because they give full details of all yr setup...... Is your hybrid inverter integrated with pwm or mppt controller?

I got it off/ through a friend as left over from a project. Contacted him recently for a friend on this forum. He claimed the panels he has now are not from the same manufacturer but a German company. Efficiency said to be better. Panels 140w @ 70 -75v range. He was not with the exact specifications where he was.Price is high 49k @ 350/watt. He claimed dollar wahala.
My system was thunderstruck a few weeks back and my EP solar 60amps MPPT cc was damaged . My measurements prior to the incident was encouraging. I generated 1.1kw by 10.31am despite the day being a bit cloudy. I am presently using an hybrid system which only calculates instantaneous yield and not total harvest. The performance seems OK but I don't have actual figures.

long time sir, Sorry for the loss we got the controller the same time back then.... Hw are you connecting the setup now since the cc is now redundant

Thanks for the info. Please what is a dmm?

@BasedOnB If you want to know how many solar panels u need then i suggest you goto page one i adviced you to before tho.
The thread is basically diy stuff, you should be able to calculate the wattage of yr ba3, load, intended hours of running on inverter yr self... A 50 watt sp is too small to charge higher capacity ba3 it can barely put out 2.5amp(max power under full sunlight) on a 150amp battery...it will take too long to charge
U said the seller advice you to get a charge controller of course you need it, that is part of what i see n i advice you to start reading the thread from page one.....my previous comment was just an overview of the issues you have.

@BasedOnB abeg stop flooding the thread with yr issue, u need to get a better wattage solar panel.... 50watt sp is just peanut for inverter setup... Maybe you should try and start reading the thread from page one......a 50watt sp won't be 100% efficient self... U need to upgrade.

Please how do I connect the cables from the DC fan to UPS in such a way that the fan is on ONLY when the UPS is switched on?

u gonna av to ground d fan negative to common(ba3 neg) then locate a point that supply only when you switch on the ups then connect the fan positive to it. U can do this easily with a dmm.

Nigerian government always like TO BE statement for project, yet most Nigerian still does not understand how they rule us..... Arnergy solar company installed 24kva mini grid solar power in some rural areas of osun state in conjunction with BOI. that was an example, there was no noise it was done great and d whole government tinz of Nigeria like to hype alot of project yet they won't do it

olabakefish:
you mean something can be done about the battery, I don't have that kind of charger, where and what type charger can do that. Please if you can be of help I'l appreciate it so much. Here is a picture of the battery

try Epsom salt it works 100% most of the time.search youtube for how to go about it......... U need to learn to do research on your own dont relay on no one

Lwkmd

olorunda68:
is this the product sir? if so, how many sachet can I use? each sachet of the ones below is 25grams sir.

if una battery dey okay b4, no try Epsom. Seriously, . U only use it on sulfated battery, it will never work on an open cell or internal shorted ba3s...... A ba3 dat reads below 12v after full charge is considered dead..dere iz alot of videos abt this Epsom thing on YouTube

Penuelseun:
Just go to any big pharmacy store, I used a pack, I bought it for #370

thanks for the hint God bless. Did u use d whole salt? What is the make of the battery? Don't mind me, i ask too much of questions....

Penuelseun:
This is it, I removed the top cover to have easy access to the vents

bros.... Pls where did you get your Epsom salt? I mean pharmacy store or which store? What quantity? How much?

Penuelseun:
Good morning @all, pls my battery only charges for like 30 minutes then starts to make boiling sound. It does not last for more than 7 minutes after I disconnect the charger, could it be the charger or the battery has gone bad. NB: the charger is not a smart charger & the battery is a 200ah zenith battery

you should know your battery is gone..... I believe most zenith ba3s are SLA . So don't think of resurrecting.

saint2ace:
Pics and price please

bought it for 2k...sumone posted d pix on page 67 and no it's a mini fan it doesn't rotate

Bosc:

got this fAN yesterday at a local electronic store here..... Firstly i underrated it because of it portability but i don't ryt now it blows serious air even on d first gear

A question for mr. Feflo...... Hw many transformer is inside the apc 1.5kva inverter?

Penuelseun:
Good morning room, my brother gave me a 200amp battery as a birthday gift about 3weeks ago, the battery has been giving me wahala since then as it does not last for more than 30 minutes, but I came across ceejay's post yesterday about adding distilled or rain water to a malfunctioning battery which I did and it has bounced back to life now, using it for 3hrs plus now. A big thank u to ceejay80 for that post. Gracias

can u upload the picture of the battery? Is it fla ba3?

obimind:
That being the case, my battery bank is 400 ah in total. What size of charge controller will be okay for my battery if my panel rating is a total of 600 watts?

well...a 150 watt solar panel has an optimum operating current of 8.38A. Makes a total of 33.52A of current but since you are will b using pwm, don't expect more than that current..... U can go for a 30amp(cc) or 40amp(cc)
40amp pwm cc is not common.

Guys hold on, If someone call you to install solar system, d approximate load is 400watt, to b powered for 12hrs daily.... N somehow you go ahead and use just 2 batteries;the battery may perform excellently for a while after mayb a year i sweardown dia will b a great decrease in power backup.... Nigerian don't know how to manage loads especially those that don't have full knowledge of renewable energy... They always think its like gen. Some clients allow battery to get discharged until battery get low... D battery life won't last if it keeps occurring, that's y DOD is always important especially if you are installing for someone... So u won't get a bad impression...... But if it's a diy person.. I tell u,you will always manage d load 2 batteries may still work.... I uses 8*9watt bulb in my house equivalent to 72 watts.... Someone who doesn't av full knowledge of saving energy might go for 40watt cfl or less...

zeestone99:
1) 2 12v200ah batteries ll giv u near 12hrs, use a 24v inverter alongside it
2) four is ok
3) 60amps is gud, so incase u increase panel in future, u dnt v to wori abt charge controller

oga zeestone99 2 batteries won't last dat long it better u tell d truth,come on u didn't even consider DOD na....n d solar panel... Hmnn 1020watt total of solar panel? It's not enough.Hw many hrs of sunlight? 20? mppt cc is okay.....

feflo:
You have done a really good job and i'm impressed.

tnx. u re welcome.

Is yr ups getting damn hot? Or you don't like the way u open d cover check out new mthd to position cooling fan to yr setup... It's cool visit https://www.nairaland.com/1389975/worlds-smallest-power-inverter/25

Complete view....i purposely cut dos space in d front of d ups to work as air inlet for fan which also reduce fan noise in d ups wen working, and d rear spacing also to allow hot air from the ups rush out.....d result eas amazing cuz D ups barely get warm under full load.... I also used ma hand to feel d damn hot air outlet..... It's worth trying..
Note:d spacing is on both sides of d ups

Here is the casing i used a very strong scissors to cut dos edge n plier to wiggle it out

I placed the fan very close to the transformer, and glue it.

@feflo y don't you try another method of allowing airflow in the working of yr ups.
Try placing the fan airflow facing the transformer n cut d rear back of the ups cover, hot air will pass tru d place....... I think it's better than yr suction method....i can give you instructional pix if u want to know about it.

ceejay80s:
Thanks ,airtime sent

#confirmed!!! Thanks v. Much

Happy 10 years anniversary @ceejay80s u will live more to celebrate more..... More power more battery amps more greenlife
Na mtn i dey use o, 07069461846.

Some dey kip our millions 4 pocket silently una no knw self... Wu u won mob? Wait wu u epp?

Valto:
not planning to go off grid with just 400watts panel and 2 batteries. but i decided to go for a very good inverter once and for all so there wouldn't be any need to change it after few years. all i need is to add more panels and batteries later.

u did great planning ahead.

Wu u epp.. Admin no dey epp. Ai fine nau
