So I called an installer for quotation for one project like that and this man shocked me today. He is recommending 10mm Ac cable for the PV (Is this even possible?)

I've heard bassdow talk about using thick Nepa Aluminum wires in place of dc cable to save cost, so which one this installer dey call 10mm normal AC wire 😂.

Told him straight up I want DC cable coz I no fit shout. Abeg make una educate us if this is feasible and what are the likely risks involved for educational purposes.

jFrankNorfleet:
I was just talking to a dealer this morning and he suggested similar to what you did

Can you educate me more on the two wattages printed at the back of the TV in the below pic? Why are there two wattage?

The typical power is what it actually uses under normal daily conditions(30w) then the max consumption is 72w(meaning if you use the max brightness, or other settings that can increase power consumption). Then the standby isn't up to 5w. I used this tv for 4years and gave it out recently. It's a good buy

wow, what your inverter spec boss?

Tdoctor:
Check the contacts between your battery and inverter to check if there is looseness or burning, as the battery may not have been charging.

that's another possiblity especially since OP didn't state if issue started all of a sudden or gradually

if you doing high voltage solar setUp, where you mostly series the solar panels in a single string, you could get away with 6mm Copper cable though I often suggest minimum of 10mm for future proof so you don't find yourself having to replace cables it no longer fits after upgrades.

As for the NEPA Aluminium cable I often suggest, it's mostly for those who can't afford Copper cable (NEW / USEd) and for that, it works because it's what I use for one of my setUps since Yaradua's government.

If you want to properly replace copper with Aluminium, you would need a thickness times 3 of the copper equivalent e.g if you needed 6mm copper, you go for 18mm Aluminium but that's only if your current is very high e.g doing 3s3p with 400w solar panels else those ones they sell down the street for less than 20,000 naira a bundle would happyly serve you even if you do 5S2p.

But then again, whoEver is doing the installation need know how to connect them as Aluminium is soft + you can't just twist it anyHow like you do with copper

at least you have done experiments with it and have knowledge…Cause that GBM battery nah rubbish normally

Certified rubbish I swear, if sun goes down it will run down if sun goes up it will go up. Na just light and phn I d use am for once sun is down

You got something as GIFT yet you wanna sell the previous one. Is it a CRIME to reciprocate the GIFT giving abi your own na One-way traffic?

if person carry better battery give una now, na same Una go talk say e too cost. When I got into Solar newly, na so I dey change battery almost every 8 to 9 months till I grew sense.

The Used ones I currently use now, don't see myself having to replace them even in 3 years time. Na so e suppose be.

Thanks for the response I have attached the picture of the inverter and battery to the post

justasitis:
What’s your battery type and capacity? Posting a picture of your setup here will help us highlight and proffer solution.

Thanks. I have checked it. No looseness. The battery is charging, just that the inverter doesn't make any noise again when it is charging. Before, it use to produce some humming noise while charging

Tdoctor:

Thanks so much. The TV also started shutting down the inverter this morning. But bulb and Fan are still working fine.

bassdow:
Obviously your battery. Wonder the kind of battery una dey use wey no dey last more than 2 years. So long the inverter only trips when heavy appliance e.g Fridge / freezer is connected, means the battery is gone. One to believe this didn't start overNight

Update!!!
I called the engineer to help me diagnose. He detected that the battery terminal going from battery to the inverter was burnt and partly broken. Reason for the tripping off when using heavy appliances. He changed the wire and everything is working fine now.
Thanks to everybody who offered advice on how to go about the problem.
I appreciate each suggestion.


Hi Engineers!
My 5Kva Felicity Solar inverter now goes off immediately Nepa takes light. It can't power most of my home appliances anymore without it tripping off.
It has been powering every items in my house since I bought it 2 years ago but now, anytime I put on AC, Fridge or TV, it goes off. Bulbs and Fans are still working fine.
Also, I noticed that the inverter has stopped making the humming sound or noise when charging with Nepa light. It is always quiet now when charging.
Please, I would love to know if the inverter or battery is what is faulty.
Attached is the picture of the inverter setup
Thanks

Bro, na your battery

Boss it was a starting point. I learnt the little I know here, I knew that there are better ones but I just needed to start as at then , and to be frank the battery have saved be alot of bills and contributions for this my street. So far so good it wasn't a bad investment. A moving man gat to the move. Na who get sense the use solar las las

father Laud…how many panels do you use and what’s the wattage? Which charge controller? Mppt or pwm?

Sorry for too many questions

chief even those used batteries sef nah luck…not many of us can identify good used batteries.A friend used a voltmeter to read one battery showing 13.8v ,.he bought it thinking it’s good and clean..only for the battery to drop to 11.6v under load…Bad battery !

it's safe to wanna assume the battery is gone BUT would suggest getting an experienced person to examine your setUp. A properly cared for battery of good / average quality shouldn't packUp within 2 years

your friend funny . unfortunately, checking for voltage ain't how to check battery health.

Please where can I get a pot that will work adequately with this induction cooker?

codemaster2much:
honestly, this induction cooker is amazing! You made the right call by not buying the version that includes a pot. The bundled pots are usually way too wide for the actual heating surface, which is marked by the white circle. Using a pot that is too large causes uneven heating, leaving parts of your food undercooked. Once you pair this cooker with the correctly sized pot, you will be blown away by its speed and efficiency. Plus, even when running it on an inverter or a prepaid meter, it is still significantly cheaper than using gas. It is a superb investment!

Sorry for too many questions

Started with powmr pwm 80a and 4 200wat used pannels. Later got 4 420w pannels (used) but connected 3 cuz of roof space, connected the 3 420 to sms mppt 60A. So far so good even as I type everywhere good so long as say sun the shine. My Airtel 2.5kwh frm cdcare will soon arrive and moving man go still the move .

When I moved from sealed lead battery to a 100ah lithium battery, It was like I was blind and now I can see. The difference is like night and day. I am currently on a 12v system but with a 4kw battery. Next upgrade náà 48v. Me sef Wan dey use a and induction cooker

sharp… the best investment is that your lifepo4 u just bought…you will enjoy it….. I use a transformer based inverter with my lithium battery (solar for charging with Mppt cc) I want to upgrade to hybrid transformerless but my problem is lightning,,I have much here during raining season and I Dey fear for the inverter..my current inverter is rugged and I haven’t even had issues since I got it even with all the lightning thunder I no Dey put am off..


I just one relate the later innovation but I Dey fear…I heard hybrid is more efficient in term of power consumption

bro even a taico 1.28kwh battery is better than 90% of lead acid batteries being sold at alaba
