Thanks for the intended patronage and recommendation, baba. Konga's algorithm doesn't implement changes immediately. I don fight them tire. I am currently out of stock on the controller and paused the listing. I wonder why people can still see it.

The controllers will be available from next week, but sadly, price will be a little higher, but not as high as Jumia's...lol

You legit intend to arrange 32 units of wet cell batteries in someone's house?

Moneyboyz:
Battery is still in warranty, I've only used it for a year and 6 months or so.

During the day I use it with all appliances from overn to freezer to ac to pumping machine and washing machine.

At night it goes off before 2am even when I only have 1 bulb on or none at all. Sometimes it won't go off at all and have like 70 percent in the morning on same 1 bulb.

I don't even have the receipt so I'm not sure they will be willing to fix it or anything.

Both Hauwei and Mantrac are reputable brands. However, because they are used, there might be some argument as to how much life is left in them. However, being LIFEP04 batteries, they will still have a some juice left in them and will serve you better than some brand new chinko lead acid batteries in the market. Some questions you can ask the sellers:
1. How many years old are the batteries ?
2. What is the number of cycles that the batteries have been discharged ?
3. What were the batteries used for ?
If you can get some satisfactory answers to these and the price point is right, i see no reason why you cannot go ahead and purchase. Bear in mind though, that being a used product, you should have some lower expectations in terms of performance. Certain LifeP04 brands like SRNE advertise an 80% remaining capacity after over 6000 cycles of charging and discharging their 5.12kwh batteries (51.2v 100ah). You can research more on the model number of these batteries and see their spec sheets. But all in all as long as they are in good condition, i will take them over a lead acid battery any day.

bassdow:
you want to add the new battery seperately, or pair it in series or parallel to existing battery bank ?

Thanks for your input, I have a washing machine, 1.5 HP Inverter air conditioning unit, Deep Freezer (I think is about 200+ liters) A small LG fridge, 65'' Inch LED TV

But out of the aforementioned appliances, I tend to do power management when the inverter is in used and also depends the last time NEPA light or generator was used to power the chest freezer..

The Chest Freezer will mostly be used on the inverter at least 3-4 hours daily depending on the cold state of the freezer...

TV is definitely gonna be in used with my starlink Internet at night.... Other items will be off... I don't even intend using my air-conditioning unit or Washing machine with the inverter, My generator or NEPA light will power these items when needed and i have a solar rechargeable fans for ventilation.

My budget for this system setup is tied to the quality of the tall tubular battery to be used, Inverter system and panel.... this can help me tailor my budget, hence the reason i needed some answers and recommendation to my questions to help me plan towards it

brightk:
Abeg for us wen nor get money 4 tier 1 panels wat is d way forward..

Does flexmax at night, display sleep mode zzzzz.

samnaija:
Flexmax has a easy equalization interphase, switch it on anytime. Others are ok, but flexmax is better.

Moneyboyz:
I don't know how to set the charge controller.

It's all connected in parallel, 24v 200w x 6 in parallel

zeestone99:
Try it on bypass. Did your installer install a bypass?

Obascoetubi:
SO LITHIUM BATTREY NOW BEST?

I'm noticing most lifepo4 batteries on aliexpress is free shipping and highly affordable if you can get the dollars at bank rate. With $450 you can get 8 cell 3.2v 280 to 310ah shipped. I mean can it all be a scam?

Juror:
Use a trusted multimeter to take readings and compare with the bms. I'll suggest you trust the BMS more.

What brand is your CC ?
is the felicity inverter the same as the one in the attached picture?

earthrealm:
get a 12v 200ah to 280ah lithium battery for about 300k to 400k abd forget about buying battery for the next 10 to 15yrs. or get a 100ah model for less than 200k if funds is a constraint
@valto advertised some units a while ago

Namzy:
What does the inverter say the voltage is during those periods?
Get a trustworthy multimeter. It will solve most of these problems.
I also own a felicity 100a SCC and I know the voltage reading is not accurate and is usually higher than stated, but luckily I have a bmv battery monitor and multimeter to counter the error

SoftHeart:
Type it as two words, not one word, it will bring a few results.

ComeAndobo:
No. Though I'm not a republican but Electoral college is one of the checks and balances needed.

Imagine we have electoral college in Nigeria. Kaduna, Kano and katsina will have a fixed number of electoral college votes even if they continue to use under age kids and encouraging overpopulation dey born like rabbit.

With popular votes, the Northern political house will continue. That's their strategy. Popular votes.

Infact Maybe local government can be our own electoral college. Lagos has 37. Katsina has 34. Make we dey count am like that.
