One 100ah battery
One 900va inverter
Installation
100k

please bros, when a load of 100watts is connected to it, how long will the battery last?. thanks

feflo:
Any battery that's not up to 12v is called a cell. 2v, 6v batteries are called cells. What it basically means is that you need a combination of cells to make a battery. In this case, you have 3.7v 8ah cell, it means you will need 4pcs, to get a usable 12v system. 4pcs gives 14.8v 8ah, 8pcs gives 14.8v 16ah and so on. You could vary it to get your desired voltage and amphour.
Thanks

thanks bros but using this how many pieces will give me a 24v 100ah bank and how long will it do on 200watt load. thanks

How many pieces will give a 24v setup. Gud morning.

bros why is it that we don't talk bout wind turbine, is it that it is not effective in Nigeria?.

gurus, why are we not taking about wind turbine or is it that it is not applicable in Nigeria?

Gud morning bros, pls how many of this battery will give 24v pack.

please bros, how long can this 12v lifepo4 lithium battery back up or last.

I could give you this fan for free, the one in the picture will work. On the conversion, i guess i did a detailed explanation on how to connect the cables, check the previous pages of this thread. Additionally, when you get the Fan, I'll be more than willing to assist in any way i can.
thanks.

thanks bros..

Gud morning bros, please can this 24v cooling fan from Jumia fit into a converted UPS and can you show me directly from panel of 1.570kva UPS where to fix positive and negative cables of the cooling fan. thanks..

Bros, please I want to know the price of the following in Lagos : 1. 24v and 12v DC cooling fan. 2. DC circuit breakers.

Abigai:
Bros thanks, explanation well understood..

I have a Bluegate 1.570kva/24v UPS, 12v/24v solar charge controller and 300w×3/24v solar panel which I use on my electronics and it do power my LG fridge of 110w successfuly, bros any advice?.....

feflo:
Thanks sir, couldn't have said it better. The buzzer beeps intermittently to remind you that the input is off and you are on battery. The UPS is designed to work for about 10 minutes, reason why small battery is installed. Now you want it to work for longer periods thus the beeping becomes annoying.

Thanks

Bros thanks, explanation well understood..

mahkanjuh:
So, it won't be making that annoying continuous beep sound normally found in UPS, it's like you are muting/muffling the sound

Thanks for the explanation..

Bros. good morning, from your explanation on how to convert UPS to an inverter you said the buzzer on the panel should be removed, why? Sir..

Namzy:
I don't understand are you comparing 150w to 300w or 150w x 2 to 300w?

I am talking about their efficiency one 300w and 150w×2 panel ie charging capacity...

gud morning gurus, 300w and 150w solar panels which one is more effective, it because the person who installed my 300w/24v×3 panels said 150w panels are more effective. thanks n happy Sunday...

NiyiOmoIyunade:
Both diagrams are not ideal because they are taking power to charge source or power loads from the same side of the battery bank - cable resistance through the battery links will mean less current to the lower portion of the battery bank while charging and more strain on the upper part of the battery bank while discharging.

Ideally you should move either the positive or negative inverter cable to the lower part of the battery bank so that positive and negative cables are tapped from opposing sides of the bank.

In a pro install, you would not parallel the two 24v banks directly but rather keep each bank separate and independent and connect each bank directly to a suitable bus bar for positive and another busbar for negative. You would then tap the inverter positive and negative connections directly from the bus bars.

Oga Niyi pls can you show me a diagram that will further guide me. thanks

Gurus diagram 1 and 2 which one is more accurate for 24v setup looking at the AH. thanks

I'm not sure Ojeysky is a marketer o. He's a consumer like us. I stand to be corrected o.

Justcallmenuel will do justice to sale and delivery for you.

please bros connect me to the the guy...

Ojesky, I live in Minna Niger State, please can u help me get a trusted person that get this 12v, 34watts, 56" ceiling fan from Lagos, I Was told the price is around N15,500 and N13,000..

Please, can anyone recommend a good 100ah deep cycle battery within this price range N30,000 to N40,000. Thanks...

Gud day audience, do anyone have an idea how much this ceiling fan cost (56inch 34w 12v ceiling fan with remote control and led light) thanks...

ojeysky:
Oops that doesn't sound right, what's the spec of your ups and your panels? Especially the voc

My UPS is 1.5KVA/24v (Bluegate) and panels 300w*3/24v

Gud day, please I need clarification on solar, I have a 24v setup and my batteries are completely dead so I connect the panels directly to my UPS in the day time and it worked so I have been using it without battery since then, but will there be any damage to the UPS if I continue to use it direct?. Thanks...

Pls can i use AC circuit breaker for DC installation?. Thanks n waiting for ur response....

Please i need clarification the imported second hand deep cycle batteries and the new deep cycle batteries which one is better, because a friend that specialize in solar said the second hand deep cycle batteries are better. Waiting to hear from the gurus in the house...

Pls can this battery (2v/1000ah) give 12v or 24v?...

Gud day gurus in the house, this battery is 2v/ 1000ah please can it give 12v or 24v when wired?, advantage and disadvantage..
