Are you saying that you use an 80 watt solar panel to charge your zinox power bank?
Please I really need to know if that's what you do and how you go about doing it is very important

quite tricky.

the charger that comes with the zinox has a charging voltage of 19v with 3.5amps. your solar panel will produce something around that amount IN CLEAR BRIGHT SUNSHINE. on cloudy days the 80w panel will be insufficient. , I still suggest the 150w panel.

also, when connected directly, I noticed the battery voltage kept increasing to the the Voc limit on the panel. this is bad for lithium batteries. which is why the PWM controller whose link I posted will come in handy. it will limit the charging voltage to the value acceptable by your zinox Powerbank.

please be careful.

yes I intend getting a solar charge controller I think it's about 5000 Naira in the market.
So if I have the 80 watt solar panel and I have the solar charge controller I can easily connect it to my zinox power bank right?
Please how much is the 80 watt solar panel price currently?

I think it is better you use the blue Lithium battery as it can accept charge voltage of up to 14.6v, then buy a charge controller that has adjustable voltage while the black Zinox battery is a 16.2v battery and it is hard to see a charge controller that has the capacity of that voltage level. Why don't you just go for lead acid as I won't advise you to go the Lithium way if you are not a technical person (Lithium is very dangerous if handled incorrectly)

how do you connect AC to a ceiling fan?
I am surprised you still came here to ask an exact question I duly answered via mail, maybe you didn't trust my response. Others using similar fan should answer you.

Don't be surprised, and I hope you don't feel offended. I was just wondering if you thought it was a standing fan because getting a wall outlet isn't normally what is put around the ceiling. I wanted to see if there are other options without having to run a socket to the ceiling.

Do you mind sharing the amount you got yours? The price and the shipping separately.

Price for 3kw PIP3024GK was USD 390, plus USD 199 DHL

So, am trying to buy a replacement battery ,
Can some1 tell me how many ah batt i need to buy.

I took this battery from a ups and connected it to my panel to watch a program. The following morning i left it to charge while my wife watch tv. Unfortunately she went out and by the time she came back, all she was hearing was a shrill noise. Rather than disconnect, remove this battery and return to the original battery, she put on the tv and the noise stopped. Case settled as far as she is concerned. By the time I came home in the evening and she told me all, the battery is bloated ti this level( picture attached).
1. Can i still 'manage' use the battery?
2. What is the implication eg fire hazzard, explosion etc?
2. Why fidnt the cc trip off and stop the vharge agter the battery became full, or is it not suppose to do so. It is a 12/24v pwm
4. Would incorporating a fuse after the cc prevent such occurence in the future for even if i am using a bihger battery (100ah for example) and it gets full while i am not home, suvh can still happen.
5. I am saving up for a mppt cc (that fake/original that was a csuse of argument on this loop recently, bluegate or do: will confirm the name)

While this is mostly a DIY and learning forum, I always say the burden to equip oneself with sufficient knowledge to DIY and work safely and with minimal financial losses lies upon each person's shoulder as a standalone individual.

Lithium batteries have a nasty habit of catching fire and burning spectacularly if abused or misused.Typically the fire cannot be put out and needs to exhaust itself after running its full course.

Be careful if DIYing Lithium and more especially be extra careful if you are modifying or repurposing a prepackaged setup to suit your needs (assumed Manufacturer made it safe). Be sure you really know what you are doing and fully understand the capabilities, tolerances and limits of each part of the system you are playing with.

In the last one month, I have heard two cases of spectacular Lithium battery induced house fires which destroyed both the RE investment and significant chunks of the houses themselves.

Like I always caveat when giving free advice be it solicited or not 'Management will not be held responsible o....'

Bro,
I am SURPRISED, I feel OFFENDED and I NEVER THOUGHT it was a standing fan.
why?
Because I told you about that fan, pointed you to the vendor, even went ahead to give you tips on connection and type of wire and also told you about the adapter via mail and also my experience and those I know that are using it,
so why should I not be surprised about your questions and also feel offended about your thought that "it was a standing fan", seriously?
you fall my hand.

A battery that has swollen so is a fire/explosion hazard waiting to happen if continued in service - you should not attempt to use it - just sell off as scrap and move on.

Why did the battery swell? A UPS battery is usually under 7Ah - whereas your typical inverter battery is at least 100Ah - very likely your CC forced far more current through the tiny UPS battery than it was designed to handle hence the electrolyte began to boil and gas out (build up of pressure forces battery case to swell).

It is also possible that the CC was set to a voltage above what your UPS battery wanted to be charged at but within one day, the typical cause of such rapid damage is overcurrent - there is not a lot of fault tolerance built into a tiny UPS battery as it is designed for a very specific application inside a UPS with controlled charge and discharge.

Again to DIY properly, you must equip yourself with the knowledge required - safety is the 1st, 2nd and 3rd imperative - consider the consequences if battery had exploded with only Madam at home while you were away - hot electrolyte (acid) would fly everywhere including people's eyes and this would likely be attended by a fire as well.

With all that sermon delivered;

The shrill noise likely stopped because putting on the TV took some of the CC output away from battery to power the load (TV)

A fuse between CC and battery would prevent an overcurrent condition but not an overcharge condition - the size of panels you have is probably too much for a 7Ah battery given the loads you have running at thesame time - We also need to be sure your CC was setup to charge at 12v and not 24v that would have surely killed a 12v UPS battery.

Village pipo dinor shook hand for the matter. You are lucky. NiyiOmoIyunade has said it all btw.

Pls encourage madam to ALWAYS inform you of any observation when you are not around. No matter how negligible it may seem, and also in turn ask questions or educate yourself before making adjustments to an Electrical setup.

Some mistakes can cause irreversible damage.

My batteries are getting better the more I use them. They are now holding charges for a longer time compared to when they were new. I'm so happy & can't wait for my mppt cc to arrive

Thank God it wasn't lithium. Your house would be on fire now. See why I like my lead acid. If you over do, the little nigga will just swell up. Not like egbon lithium that will just vex and catch fire.

Please we should be careful with our DIY. certain level of hazards is inevitable but of course without experimenting we won't learn new things.

Please take some time to judiciously read/learn about these things before trying anything and also give those around you some sort of basic information about usages and hazards, and whenever you're away, call once a while to ask about it's condition/operations.

For the ceiling fan? Pls link of store u got it.

To whom it may concern:
I have noticed that not all DC fans come with brushless dc motors. Some simply use a brush dc motor. That is still more energy efficient than an ac motor, but a brushless dc motor is the best energy wise, plus it doesn't generate static noise that can interfere with radio signals. Just so you knw.

Thanks. But unless it is stated on the item package or the name plate, don't you think it will still require some tearing down to be able to tell what type of motor is inside?

Penuelseun:
You can use the solar panel to charge it but you have to be really careful when doing so. Why don't you just get a charge controller with capacity to charge Lithium batteries instead of troubling yourself if you're not tech savvy

Mine has been on 100 watts panel. The device supplier says that it can still do fine on 150 watts. There is a CC-CV board inside that handles the single port for the AC charger or the solar panel. The other board in the device is the BMS.

Only a programmable SCC can give you the luxury to programme the output charge voltage and current to the battery pack. The 4s config gives (4.2v x 4 or 16.8v). Your regular 5000 naira 12v/24v PWM SCC can only do fixed 15.5 volt output at the battery terminals. That is suboptimal for your Li-on pack. 15.5v charge will bring each cell to 3.8v which although is not entirely bad for the cell as the low discharge cut off is 2.7v per cell, but you won't be able to use the full capacity range between 2.7v to 4.2v of your battery.

So effectively at the end of the day, you will be cheating yourself.

lexi28:


quite tricky.

the charger that comes with the zinox has a charging voltage of 19v with 3.5amps. your solar panel will produce something around that amount IN CLEAR BRIGHT SUNSHINE. on cloudy days the 80w panel will be insufficient. , I still suggest the 150w panel.

also, when connected directly, I noticed the battery voltage kept increasing to the the Voc limit on the panel. this is bad for lithium batteries. which is why the PWM controller whose link I posted will come in handy. it will limit the charging voltage to the value acceptable by your zinox Powerbank.

please be careful.

@ bolded. I guess your Zinox Powerbank has some form of voltmeter added to it which was not originally manufactured in it. That voltmeter is connected to the terminals that receive the direct volt input on the CC-CV board and that is the reason for the absurdly high voltage. Meanwhile, the BMS does its good job of maintaining the cells voltage within acceptable limits.

Or so I suppose.

Good day Oga George, kindly share the pictorial diagram of your battery connection. I am amazed you don't use battery balancer.

that, along with my oversized solar array has ensured that my batteries remain in top shape these many
years, beating even the most enthusiastic predictions.
and, it's also the reason why i don't use a balancer despite having three parallel strings in my bank.

Bro,
I am SURPRISED, I feel OFFENDED and I NEVER THOUGHT it was a standing fan.
why?
Because I told you about that fan, pointed you to the vendor, even went ahead to give you tips on connection and type of wire and also told you about the adapter via mail and also my experience and those I know that are using it,
so why should I not be surprised about your questions and also feel offended about your thought that "it was a standing fan", seriously?
you fall my hand.

Pele mabinu I have explained why I thought the setup you suggested was more appropriate for a standing fan and was instead looking to see if I could get other option that does not require plugging to socket. I guess my assumptions were wrong as it seem that your suggested option is indeed the only way to go about connecting the fan. Sorry about that. I hope an apology from me is sufficient to appease the gods

ceaser:


Thanks. But unless it is stated on the item package or the name plate, don't you think it will still require some tearing down to be able to tell what type of motor is inside?

If you tear down Person market e fit tear you slap... But yh, thats a sure way to see the insides of anything
