Omo, I ain't about to do all these DIY shiiiii, I'll call the installer to come replace these batteries with a 48v pack and pay the difference, I guess he doesn't know how inefficient series charging them would be.

On my remote it is written 2 to 6 hour if u set it. but if you leave it on induction , it will come on at sun down, 6.50pm and by 2am it is off battery dead . So what I do, is on some then by 11pm switch it off then on others to morning. Most don't don't last 12hrs at a stretch at least my own and my neighbor. But because of my experience in solar I don't let them get depleted like my neighbor, that is why Mine is working while all is own has packed up

Your lamp isn't good quality.

The one at my home was installed August 2017, comes on around 7pm and I still see it on by 5am.

I was preparing to buy a few of the same Street Lights after the New Year festivities and would have trusted the Seller on his Warranty Claims but l guess he would also turn around to tell me It is just sheer deception designed to sell the product!

This does not speak well of the Seller at all, and all those who act like That.

It seems yours isn't of the best stock. I have two solar lights that have functioned quite well for over one year. They light up with constant intensity from dusk till dawn. One started acting up about 3 weeks ago (it lights up thru the daytime when it's charging but goes off at night probably after the battery must have been depleted during daytime). It also became non responsive to the remote. What I did was simply to get a replacement circuit at less than 1k5 and fixed it.

The circuits are damn cheap on AliExpress and you an DIY these lights yourself with a cheap 6v 5w solar panel (around 3k on Konga/Jumia) and two or three pieces of 18650 (BMS protected) cells depending on the duration of lighting you want. The BMS you will need is 1s Li-ion which is also under 150 naira.

Another one I DIYed has two protected 18650s and lights up from dusk till dawn with constant intensity.

can anyone recommend a charge controller with lifepo4 profiles? i am not comfortable with my current controller.......

ewizard1:


2 or 3hrs of operation?

Controllers cant guaranty constant voltage, cloud effects , bad wheather and so on. You can carry out a little experiment charge with nepa only and discharge, also charge with controller and discharge. You will notice a difference in run time. The rule is once a while charge with nepa

ojeysky:


I like to get the logic; are you saying if I charge a battery to full via either utility or solar PV the run time will be different with same load?

samnaija:

So you did not get the part bad wheather you quoted

ojeysky:


The way you worded your message is what was confusing....PV planning is important hence things like weather condition needs to be put into consideration in your planning if you want to ensure your batteries are fully charge via sunlight.

What's the name of this light? Please screenshot it

Valto:
which one are u using presently and how many volts system

brightk:


i am currently using the epever tracer 3210an series.. the websites says it supports lithium even the manual says the same thing.. each time i try to change the battery type from the lcd display i only see sealed/gel/flooded/ user-defined . i dont know if i should get the interface cable to connect to pc and maybe use the software interface to see if i can change it from there.

i am using a 24v 200ah lithium setup.....

Valto:
then use that user defined. edit it according to your battery charge specifications.

Good evening, experts and experienced users in the house. Please I need help.

I was on a budget and needed a setup that could power just a few appliances; namely, bulbs (25 wtts total), two fans ( 100 watts), and 55wtts TV once in a while. I didn't necessarily need to have the inverter on all the time. Just about 12hrs of usage was okay for me.

The Solar expert got two 260 watts panel, a 1.5kva inverter, and a 100amps battery, a pwm charge controller, totalling around 220k.

I wasn't impressed with the battery performance, but, I just needed to be able to charge my laptop and phones.

Now the problem is Nepa light charges the battery full, but the panels can't charge it. A really sunny day would barely give you an hour of usage at night with just the bulbs on and phones plugged in.

I complained and noticed he was dodging my observations that the panels might be bad. He later came and connected the panels directly to the battery and not through the charge controller. This didn't improve or fix the solar charging ish.

I've been depending on Nepa to charge the battery ever since. You can't even on the inverter when the battery had run down and the sun eventually rises. It'll scream battery low in no time.

Now, I just need a panel that can charge a 100amps battery full in the mean time. I just need to be able to charge my phones, laptop, and maybe on one 50w fan.

Will a 160w panel suffice, if yes, which?

Lest I forget, the battery lasts around 3 hours with 150w+ load. Surely, I'm upgrading to a better battery soon. Just need a panel to charge the current one in the meantime and allow usage during the day.

The 260w panels are literally useless for now. It was a scorching sunlight today, yet I couldn't even charge my phones

Please what panel can I manage in the meantime?

brightk:
it doesnt respond via the lcd interface.. My best bet is via the software interface
its a CC-USB-RS485-150U PC Communication Cable and i dont have it

Dishtech:

My Observations are as follows:
1. Your 260w x 2 is not efficient using pwm on 12v system he would have used 150w panels so change your charge controller to mppt. I think one is advertised here at 52k.
2. Check your panels orientation,
3. What size of cable use for your system.
In conclusion since you already have 520w panels already it is better to buy another mppt charge controller than to change the panels.

Thanks, Chief. I really appreciate your prompt response

1. By 12v system, do you mean the 1.5kva inverter I'm using? However, for me, MPTT is an overkill, since I have just two panels and a 100amps battery.
Moreover, the installer already connected the panels directly to the battery. So the PWM charge controller is not connected.

2. I'm not adept at this. Do you suggest I call another installer?

3. I'm don't the size of cables either. In conclusion, are you saying my panels might be good, and the problem is coming from somewhere else? I'd be happy if this is the case
