JUO:
this is from a 400w setup

do u use mppt cc?

Greetings to diy brothers in the house...thanks for encouraging us..
i have 2×90 watt off sunmodule panels,10 amp charge controller,selfmade inverter(m an eee student like building circuit), i will get battery soon, am a student n i dont av so much load just a tv,dvd,a fan n 11watt energy saving bulb.
can some of these loads be powered on during d day n ba3 still get charge via my 2×90watt solar panel ... can't afford more than does panel for now.....if it will work den i will know i need only ba3 if it won't i can hold on for ba3 n buy more panels later
i just want real life feasibility abour d panel corresponding to d loads...ideally d load can b run for 6hrs perday...

My 3 5kva luminous inverter backed by 4 batteries usually powers my fridge, tv and fans dor two days when fully charged. Now it doesn't power all these items for 24hrs except the fridge is off. What could cause this.

I have had the inverter for 8months.

possible problem:your battery is degrading
question: when did u installed the 4 batteries?
possible solution: you will replace the battery according to the spec of the present.

Hi, please anyone using blue gate inverter? I just got a bluegate 2kva pure sine wave inverter and I noticed after like 20 minutes of charging the inbuilt fan starts up with a loud noise and stops like in 2 seconds . This then continues every 20-30 secs. I do not know if this is the normal way the bg inverter works. Technician that fixed it is not sure too but seller said dats how it works. Please help .

did u just notice diz or it started right from purchase?

owemas:
pls I get the circuit diagram of an inverter with irfp250 and sg3524..can it work if I construct it?

yes it will...I already built one inverter using cd4047 ice n irfz44n transistor.

Meel:
no, dem don verify u abil

yes... i submitted my data last week Tuesday..... probably i got verified in a week...i got verified in d afternoon cuz i checked ma status earlier today wif no luck
keep checking guys all is well

#verified dept of EEE reporting!

Meel:
A week now, and dem no verify me.

dept. of eee abi?

and secondly, can you sell solar panel seperately? i need two 100watt pv or two 130watt pv..let me know the cost sir.

mr.femi are these inverters local made in Nigeria?

Meel:
i bought mine from dibu ojeride himsef gangan,(400)as per family.



But other ppl are selling it starting from 1400 depending on ur area.

lol.... Okay thanks bro

How much iz jamb admission letter scratch card? Please I want to know the price

i really thank Lord Jesus.. no changes in mine . eee in school eee on jamb portal.. m so happy

OdogwuMike:
i will pay 4000 ooo, nothin mor nothin less, send me your account details, and fone no, will like to call ye b4 i send d cash......

them no dey bargain bread oo...anyway over to mayorall

dastranger:
Really? Tell us more.. what's your battery ratings and how mny charge cycles re you getting?

i use a 1400mah battery n i get 4 full recharge + 30%> on ma phone provided i fully charge d power bank...takes upto 7hrs to 8hrs to fully charge d p.b with my 800mah charger

dastranger:
This bank is very common and very cheap. Lol...but some of them are filled with sand bags (like yoruba pple will say, eni n wafa n wofo). The other one uses different cells. So definately, sth is fishy there. smart up Guys!

na diz type i dey use n itz very strong guess m lucky

every powerbank is good but the battery inside them depends on their capacity to charge phones.. e.g anker got grade A Panasonic 18650a

jomarick:
Some of you here might be elect/elect students or graduates yet you can't connect cells in parallel,work it out with 5V NPN transistor,capacitors and blocking diode.Yet you talk about unbranded power banks,I pity for u if u fall in dis category.Una no dey do una own?

sir can u post d circuit diagram?

eee admitted aspirant,add me on whatsapp on 07069461846
