Hi House.
My charge controller drops from 5 bar ( 13.6 volts ) to 3bar ( 12.4 volts ) after full charge on a load of 150 watts.
What could be the issue ? Setup was done a week ago.

Note had to charge with external intelligent 20amps charger to full bar.

This is my set up :
1. 2 x 335 watt GCL panel in series
2. 60 amp PWM Charge controller
3. 220amps Caesar tubular Battery
4. 1KVA MSW Inverter

You installed your self right?
Just Get an MPPT controller to solve this issue.

Thanks for the response.
So best advise to prevent losses is to get a separate charge controller for both panels?
The total panels are 10. The owner initially installed 7 panels (PANEL 2), then he recently bought 3 panels (PANEL 1) to upgrade the installation from another source (Fouani).

You can combine them all in series but note that there will be about 10% loss.
with about 5KW PV, it doesn't matter.. losses cannot be avoided when batteries are full and nowhere for power to go.
If cost is not an issue, proceed to get Separate controller for the new panels.

You know say na Una dey convince people say dem fit Mix & Match Solar panels of different capacities. Now you're seeing the result.
Wonder why you guys won't let somethings be, so those who really knows what they're doing, to take such risks.

Once again, whenever you combine Solar Panels of different capacities, expect the higher ones to come down to level of the lowest. At end of the day, na you go dey cheat yourself.

The same way you dey advice on Lead-acid.
the loss here is only 10%
If the person doesn't have a choice or the panel was gotten for free or similar why not!!

Hello house. Pls can i connect these 2 solar panels in series
PANEL 1
Vmp- 35.21v
Imp- 13.49A
Voc- 42.54v
Isc- 14.23A

PANEL 2
Vmp- 43.38v
Imp- 10.95A
Voc- 52.24v
Isc- 11.77A

Pls note that both panels are CONFIRMED original jinko panels bought frm different trusted sources. And both are 475w panels.

In Series Result: 90w loss.
vmp 43.38 + 35.21 = 78.59 V
IMP = Lowest Amperage = 10.95A
That's 860W total as compared to two identical 475 panels 950W.

In parallel Result: 90w loss.
Vmp = Lowest voltage = 35.21 V
IMP = 13.49 + 10.95 = 24.44 A
That's 860W total as compared to two identical 475 panels 950W.

Good evening bosses..... Is it advisable to by pass hybrid inverter inbuilt charger and use a separate 60a MPPT charge controller for a 48v system with 8 units of 350w panels connected in 2s 4p ?

Sure, You can use an external controller with your Hybrid..

Danibestguy:
Dear Team.

Please, I have a 24v 100ah lifepo4 battery pack. Please, what kind of charger(AC) is it recommended that I use.

Note that we have regular power supply in my area and I am not planning on getting panels.

Considering my points above, what kind and size of inverter is recommended as well?

Do I get a separate charger and inverter or do I get an inverter that can charge?

Total load - 150w fridge and 80w fan primarily.. Abeg no air me bosses.

https://www.nairaland.com/390522/solar-energy-complement-fta/1585#128577092
Check the link, its future proof with 40A inbult solar charge controller... 1.2KW with 3.6KW Surge rating will handle your loads.

BlueStripper:
Good Evening Guys, I have a problem.

I recently got 2pcs of Quanta Amaron Tubular Batteries 220ah each (Brand New).

These batteries are always charged full before the evening by my 2s1p solar array setup 560amps (parrallel) and 180amps x2 (series) array.

The issue is, i get a very low runtime on just my freezer. My freezer consumes 150 watts of energy. I was using it perfectly with my Fullriver 150ah batteries (2pcs approximately 300ah) before decommissioning last week.

What could possible be the problem of these batteries? Its a 12v setup and I am supposed to enjoy more runtime but no, its been terrible. My Fullriver worked even better than this Quanta Amaron.

Should I upgrade to a 24v setup?

Charge controller is POWMR MPPT. Serving me for more than 3 years.

Please help @bassdow @valto @trippledots


N/B this is my first time using tall tubular batteries and i am so disappointed. The average Runtime with 150 watts fridge is 3hrs and battery will drop to 12.3volts.

My lithium setup 100ah carries same fridge for over 3hrs. This 440ah setup cant even carry for 3hrs and its almost at 50% DOD.

I am disappointed .

Do away with whats not working... and get more of what works !!!

Lead acid has this poor charging algorithm, they take longer to charge...and at low amperage... Self discharge dey too.. Make those preaching Lead acid should continue..

bassdow:

I dey here SIR.

but you failed stating that, those people suggesting people go for leadAcid batteries, do so due to the non-Straight forward difficulty in purchasing good quality Lithium batteries.

Just like I didn't dodge when you shyly called me out, hopefully you don't whenever anyOne cry about how their expensive lithium batteries.

why ain't ISPs (MTN, Airtel, etc) using Lithium batteries on their network masts, or, Banks, etc, in their setUps ?

story...

Valto:
4pcs of 135ah lifepo4 cells is 280k
4pcs of 150ah lifepo4 cells 360k
@ 80 or 90% DOD, capacity still bigger than 12v 200ah lead acid, will still last atleast 8 to 10yrs

Imagine someone will be replacing his Lead when 12V, 200AH is selling for 1M... 3 years later...
Where are those advicing people go get lead acid?

futurenix:
Good evening all
Has anyone encountered the new felicity 10kwh lithium battery switching on normally with battery voltage and percentage displaying but no voltage at the terminals?
Charge controller detects no battery connected.
If yes, pls how did you resolve it

There is a warning sign Check what that means
... also check the breaker..

matify83:


Yes!

Ihp is like 740W Approximately runs for like 1hr 30min to bring my tank to brim( though not totally empty)

Philips pressing iron is 1kw.

Ironing is even better and less draining on the batteries than pump machine. It goes off when hot and starts again. Unlike pumping machine that runs continuously.

Just leave those people who are doubting, they may have been scammed by installers using fake products...

Those people who don't believe you may also be using power-hungry devices and don't know how to manage their power usage efficiently.

They don't understand, that Iron doesn't consume much after the first 2 to 3 minutes, also Pumping machines are now efficient..

Problem solved.

This is Catl 302ah that I want to couple for someone. As usual, I hooked it up with bms to move the charging limit to about 56v before carrying out the final top balancing.
Tonight, I decided to put heavy loads on it and observe the cellvolt diff. I was shocked to notice that almost all the Eve cells I've carefully top balanced has never performed as good as this. The cellvolt diff has always been higher than this with the similar loads.
Eyes are too much on Eve. I will pay more attention to Catl henceforth.

CATL no be EVE mate...

Airtel "5G" unlimited. It's supposed to be 20mbps but I hardly ever get above 10

10 Mbps is more than enough for any household unless you want to download Big files.
How much and what router?

GiggsTk:

It's same problems then... I'm just already so stuck with the software or pixel experience...if the 8 still has same heat issues...then it's to buy 7...but I'm really asking myself why I should buy the 7 because the problem is still there....so much momney for a phone that will heat up at the slightest tasking challenge

Make una dey give credit to phones abeg, They run at a high-performance task without a fan in it, Even laptop doing similar task needs Fan in it...

A laptop does basic video calls, A phone does high-quality video calls.

I dont really have much idea about orientation. I have not mounted it on my roof yet. I just placed it outside for now. I want to add one more 550w to it before I put it on the roof. The wire length from the panel to my MPPT charge controller is 10yards. I am using a 6mm pure copper wire. The panel current is rated for 13A under loads. To troubleshoot if it was my wire that was the problem, I actually took both my controller and my battery close to the panel and ran the original panel wire straight from the panel to the controller and I was still getting 275, 280W max at peak sunlight. So I dont think it is my wire. It is a single 550w Jinko Panel bought directly from Foauni stores.
Here is the picture of where I placed it. There is no shading at all. Ignore those other two panels. Those were the first 300w panels I bought. Those ones too are giving me 100W max per panel. So I have been wondering what is the problem. Lets assume those 300w are fake panels, this Jinko 550w is definitely original as Foauni store does not sell fake things.

If a Jinko already produced 275W which is 50% of its capacity and your 300w were doing 100w which is 33%...
it means your the Jinko already performed as Top Tier Panel.

Your Charge controller is doing a bad job... Change it to another one..

Also note the Current Weather is very bad!!

JoeSef0:
12v

Hmmm, this is not efficient, 300watts panel is connected to PWM CC on a 12V system.

JoeSef0:
Thanks to everyone input to my case earlier
I've gone to install an external CC and the series issue has stopped. Everything is fine now.

Just a quick question
How many amps should a 300*3 mono solar panels produce at peak Sun?

PWM Controller?
Is this a 24V system?

ibawon:
I just complained to customer care regarding wi-fi issue saying some of my devices could not connect to 5ghz despite having the technology. Na so them send me new router and cable, then sorry for disturbance free 1 Month subscription. Walai Starlink dey try

This is kind of service level you dont get from Naija ISPs...
this is the international standards we are missing in this country.

Please my LG smart TV is only seeing the 2.4ghz network and this causes buffering while streaming. My Ipad is the only device that sees the 5ghz . What can I do to be able to connect the tv to 5ghz network?

Split your Channel on the Starlink app first, so you have 2.4 and 5GHz seperately. then your TV can see both if supported.

One of my socket live and neutral momentarily touch each other, my prepaid meter tripped, no light on keypad and no light in the house.
Checked meter on pole no light blinking.
What happened? And please house what can I do?

Call Electrician to help you switch on the Circuit breaker.

primefaith1:



How much were you paid for this shit review?

Since you said you are in Lagos, will you accept any challenge on this review?

So you no dey watch youtube reviews on batteries where teardown, capacity test is being carried out?
do I need to be paid to review a product that was purchased with my funds?

The similar capacity issue with C-worth the company does not even understand what 80% DOD means! just saying rubbish. The pack had 85AH batteries inside and was labeled 100AH.. and the only explanation was that the 85AH was related to 80% DOD, even when I showed a screenshot that I discharged from 56V to 42V which is 100% DOD.

sharks776:


I beg to cheap in here. I do the same analysis when buying solar PV.
Using the above analogy, in my case, I regard/use the PV that gives me the lowest cost per cell as the most efficient in terms of cost.

Therefore, the 600w is the most efficient and cost effective PV because it has the lowest cost per watt (i. e 0.0029 watts per dollar)

so you want to pay more for less wattage per USD, interesting...

you will pay 1USD for 0.0029w instead of 1USD for 0.0033w...

Please who has used this DP led rechargeable fan.

Is it worth it

this is an Hand fan

IMO, Grade A cells aren't accessible to random end users.

Depending on your Source, Automotive Grade A cells are available to end user at High cost!

Valto:
2yrs might be too short. the price of original 200ah fullriver, if u add small money will definitely get u a 12v 135ah or 150ah lifepo4 lithium battery which is far better and will last 8 to 10yrs.

No dey give people advice like this, LFP is too expensive.
he should buy another one.
