@anochuks08 can you show the pix of the inverter u proclaim you build?

anochuks08:
I am one hell of a person that is usually satisfied with my own build. I have a 5kva Low Frequency inverter built with a friend. The efficiency of that inverter superceeds all I ve come accross. The quality factory made ones are overpriced and the cheap ones are useless. The inverter powers all my household items, from Fridge, Pumping Machine to electric kettle.
I will be building 9 more panels. The bet was cos he didn't believe solar panels could be built DIY. Making the first panel seems tough, but afterwards, it becomes easy. I used to be scared of breaking my cells but thats in the past now. You will always find techniques that best suit you. I can build 2 working panels everday. I discovered that most of them outside build their own solar panels.
If I have time after this, I will build solar trackers. its fun though

awesome, #am_impressed #goodjob #keep_it_up

anochuks08:
Am trying to go offgrid on a small budget (dou most of people around said its not possible) but am 70% done. To get this panel up and running, I will suggest you look for old windows frame, this will help you save cost very much. But I couldn't get old window frame so, I had to build one. Here is the breakdown
1. Frame = 1800
2. Glass = 1300
3. Solar cells (I don't go more than $0.5 per cell)
4. Encapsulation, 700
5. Wire = 150

NB. I had a bet with a friend that I will get this panel up and running, he said I couldn't. His word was that he ll build me a 60A MPPT charge controller if I win. I won this bet and he will deliver my charge controller before 12 noon on Monday

well, i didn't know you are on bet for building it. It a great achievement tho.
But the stress in ordering cells(probably online), d cost 0.5$/cell, those frame and glass thing......would probably be better to buy a factory made.
There is also risk of breaking cells during the build which greatly reduce d panel efficiency...... Maybe it all worth it. U bet u can tho
Am impressed.

anochuks08:
Testing Complete.

hope you didn't spend much to get that thing up n running? It a 65 watt solar panel......Can u tell d house the total amount you spend on this? #goodjob

anochuks08:
Building some solar panels for my inverter

what is the maximum current of each cell?

anochuks08:
Encapsulation, should take roughly 2 days to completely dry

nice job. I believe each cell are of 0.5pd wt is d (I) of each cell?

richi, how i wish Nigerian government work this out. Lol

feflo:
APC 1000va conversion

can dis power a deep freezer of about 185 watt(+compressor surge) ?

coderXO:
I asked you particularly because we have the same battery. The value changes from battery to battery.

Im2Busy2Bother, my smart charger turns off at 13.15V and I know verywell the battery is not fully charged.

Starting at this 13.15V, my inverter turns itself off with sole load of 100W fan after 3 hours max.

I take my battery out in frustration to my generator and use the 8.3A charger on it and charge for about 3-4 hours, when
the battery gets to about 14V I disconnect it. The battery unloaded comes back to settle 13.3V. At this 13.3 when I hook it back to the inverter, the single 100W fan can last 6 hours.


I am trying to pinpoint which is faulty, the battery or the charger.

When I first purchased the battery, the I remember rest voltage was about 14V (not 100% sure), now I can never get it up to that anymore.


Dunno

that is the limit to all these chargers, different manufacturers different circuit built in them. My old charge controller settle at 13.3v as float charge(got damaged now) , my new solar charge controller goes to 14.8v for 10 minutes before resting at 14.1v as float charge.... A lot of electronic design changes in performance and accuracy
I think I am enjoying more from d setup now... Battery rest at 13.92v at night(if it get full at d day)

timifakay:
Sign of DIY. I didn't understand how to attach using the holes under the panel, so I had to attach wood to the holes then wood to the roof. Adapt and survive.
Please enlighten me about the proper way.

honestly it isn't bad idea someone did the same on YouTube chk diz link

timifakay:
Can't be enough for 400ah, would take about 2 days to charge one 200ah battery fully from low state.
@coderXO
Got it at N Olalekan Batteries, Ifeleye market, Oke Padre Ibadan

lol i like yr homemade wooden roof mount... Kudos

zeestone99:
Our solar charging booth for phone, rechargeable lamps, it is very good 4 pple in remote areas,and for ur luved ones in d village.

Call 08117398294, or email Info@monzpowersolutions.com for more details

nice innovation... I think Nigerians are just waking up from slumber.....#solarthegreenway

saint2ace:
bobojoshua what exactly is ur question?? E be like say that ur new phone dey show u pepper ; u go quote and never insert anything abi change dey follow affect your phone.

On the lighter side

i tire oooo

cooldipo:
still waiting for a response @ all

could be a relay's fault shaa... Yet u need help

zanyzara:
@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?

did u say 1.4 amp is d max current from 520 watt solar panel? Something is really wrong av seen 180 watt sp pull 9.2amp in straight sunlight

kogistar:
what will happen, if i use solar + inverter ? because no money to buy battery, i want to use it in the afternoon

it won't work that way and I pray you don't destroy the inverter internal circuitry cuz sp voltage is always higher than battery voltage... Buy battery and enjoy your setup.......

kogistar:
no, i mean solar + inverter, i don't plan to buy battery

if you have been following the thread from page 1,you know you probably can't do without battery in yr setup. Battery serves as a buffer between your inverter and solar panels....

kogistar:
can 300w solar + 2kva inverter, power 4 tv & 4 decoders? can it power fridge?

What matters is your battery, is it having enough capacity to run your stated load at your estimated time ? 300watt sp will always work even less than that d problem is that it will probably take days to replenish the battery energy back with those appliances......

@bishop4life u need work more on your practicals all this IF statement won't help you to learn ooo

@bishop4life where you at? Pump man... Here i got piece of cake for yaaa

bishop4life:
I think 12v ups will drain faster.
You wonder why? "power loss due to induction".

please i will advise you not to jump into conclusion abt inverters.... Am sure you don't even own a multimeter what do u knw abt powerloss due to induction? U won prove u sabi something sir...... But i dont feel in 4 dat....... I sound rude oh yea..... I dont like people talk abt some one day Google search and come to d forum like they are professors in physics.. Break dat.....
@coderXO already said it all, the simple answer is no matter the configuration be it 12/24v, with d same battery amperage capacity, that will only determine the TOTAL energy in the setups. But the rate at which you draw load from Those inverter will determine the run time. Simple as abc.... Wetin be power loss due to induction.......froshh

Blankstare:
Man

what ya prob

ceejay80:
My brother e no easy, if I start charging now, this thread will die, trust nigerians, dem like free things, yesterday I go buy charger and ups for a nairalander that stays in oyo, I almost got crushed buy a speeding car when I go buy ups for army arena oshodi, God forbid that driver suceeded, the nairalander wey send me go think say I don carry him money run, e no go know say man pikin don delete.
The stress of jumping bus and carry heavy loads too much

na so life be bro....... Dat naija 4 u
U do hardwork for some people, some will appreciate and some won't give you kudos not even thank you.... They will always show up if something is wrong with their setup.....datz life.

oloet:
only pure sine wave inverter can carry fridge

modified sine wave inverter can also be loaded with freezer

if anyone has d touch of sony xperia L should pls holla. probably lagos.

one if d wise people have known to be are the psquare, they got strategy........they MIGHT just be playing prank on fans,wanting more attention on them.... and m sure they will reconcile n get over it...n u guys b like..... what next x going to happen? lol.

ceejay80s:
Is ur ups bluegate 650? If yes, unplug the ups from electricity connect only ur battery to the ups ,if the fan spins without u switching on the ups power button, then u know its not ok, cos ur fan will run morning till night, but if u connect only to battery and u switch on , the fan spins and when u switch off the fan stops then its ok

yes. exactly...d fan start wen i switch on d ups only....i used to run d ups with external fan before(small usb fan) which makes it bulky.......with diz fan,its very compact now....... tnx 4 d idea once again.

patrickkkk:
ceejay, pls help me with the connection of the fan. My own single battery 650v bluegate ups has the biggest capacitor labelled 35v and the smallest capacitor reads 25v and not 12v like suggested. How do I go about it?

capacitors are always rated higher than the voltage passing through them.... d max volt around d 35v might be 20sumfin volt.... so no worries. what you want to make sure is to find a capacitor that will start d fan only when you press d start button on the ups..... if u connect it to any cap, d fan will b running 24/7 so far d ups terminals are connected to the battery.

@ceejay80 well i didn't notice any difference,there was a capacitor in ma ups dat reads 28v when i start it up... i uses 12v. setup though. i was afraid it could destroy the fan...i found a cap dat reads exact battery volt, so i connect the fan through it........ it spins v. fast. it draws 280mah on my meter.

oya continue
