Lastly pls what is your ampere reading on mppt and pwd

So far so good my ampere reading of the 3 panels from my Felicity Mppt has never exceed 11amps . While my PWM gets so close to 18amps . So like I said it’s the settings that matters.

HeavenlyBang:


Well, that's just not true is it. I used to believe that till the day I hit 95%+ output.

Canadian don't produce lower wattage panels, I'm pretty sure that it's those relabelled, repackaged Alaba type that the true capacity of the said 250watt might even be 175watt

You have answered my question..it really means mppt controller is useless for 12v set up...cos how can you be getting 11amp on mppt and 18amp on pwd....the purpose of mppt is to convert excess voltage to ampere...if you are getting 18amp on pwd, I expect you to get 22amp from mppt.... There is something wrong will all this mppt...it is just a waste of money..I regret wasting my money on mppt... I will need to get a bigger 60A pwd controller cos I intend to get 2more panel

Yeah sure, it should do the work.

Juror:

With a 37.2V Voc and 25 units,

I would do either 11s2p or 8s3p depending on other limitations like Max input current of the inverter.

It could be possible to do 12s2p but I don't like extreme sports.

8s3p is cool.

@BigDickProblems

What i really noticed about mppt is the higher the sunlight the lower the voltage and higher amps, the lower the sunlight the higher the voltage and lower amps.


Like in the morning I get like 24v and very low amps but when the sun gets hotter the voltage reduces while the ampere increases but the voltage would never go below 14.6.


And one advantage of mppt is even with cloudy weather's or little sunlight it still produces current as high as 80watts even during rain fall sef. But a pmw would never produce anything in that weather condition.

Honestly it’s hard to say these days especially with my experience with Felicity controller. I had the thought that’s it’s the deal!

I took a temporary conclusion that the MPPT is way better than my PWM. Why? Because the Voltage from the panel can be mistaken for the Charging voltage (SCV) . Now it all boils down to the settings on your controller. My 60Amps WPM can allow me set my charging voltage to values above 15V , 16V or 17V (which is not good tho) but my 30 MPPT will limit it to 15V maximum. This is an important factor that determines the charging current too.

One day I did a test on both and set the charging voltage on both controllers as 17V (for WPM) and 15V for the MPPT. Lo and behold I was getting 300W+ (17.1V and 17.6Amp) from the WPM while my MPPT was giving me 150 to 165 Watts.

Ever since that day, I concluded on an unpopular opinion that MPPT, like they say, is for Larger Battery banks and not for small 12Volts systems. And that it is only better than PWM when you cannot configure your PWM correctly.

Most likely these are repurposed batteries and they still hold quite well just like new. That is how valuable Lifepo4 batteries are. It takes time before they lose capacity and when they do, they can be repurposed and reused.

Despite the volatility of forex, i foresee a time in the nearest future when Lifepo4 batteries will become very affordable.

mppt is not useless, it just works better when the input voltage is 2x, 3x or 4x more than the output voltage. Kindly share a picture of the spec sticker of your charge controller

What could be responsible for this burn and cracks?
This is a 6yr panel but two of my panels suddenly one after the other developed this syndrome.

Is this panel by chance still functional?

I made a very huge mistake on my own part, i didn’t take any readings when I was still on the pwm cc. I got rid of it quickly after the installation.

Low quality, often cheaper than premium PVs, are prone to failure after some years of service. This failure is attributed to low quality part used to make the solar panels which makes them cheaper than the premium brand. Most that I know of fails after 3 years. This one even tried to get to 6 years.

I wouldn't use the solar panels if I'm you. Best to discard it to replace it.

On the other hand you can always check to see if the solar panels are correctly installed. Check out a good case of bad connection that may lead to catastrophic failure here:

Professional installation Cost money.
Its better to pay for quality than pay for consequences of bad installation.

Thats a whopping 8M plus worth of system.

I experienced the same thing in the Tokunbo panels i bought after two years and one got burnt out. After that i had to change the entire panels to tier 1 panels.

what might caused this are;

1. when you do not use MC4 connectors but rather cut the wires and do the connection thereby creating more resistance for the flow of current.

2. directly placing the panels on the roof without allowing for air flow underneath the panels.

3. using wrong gauges of dc wiring.

I will advice you to replace that panel with a new one

Calm down ooo before u go hit wall.
Mppt is for any voltage.
Repeat this test during raining season u will understand better. But pls RULE OUT MPPT NOT FOR 12V UP...

Pwm is almost dead during cloudy days.
Probably your mppt is another glorified pwm.

Note too that pwm pushes amp at intervals while mppt is continuous to a large extent.

You will get same result with the proposed 60a pwm.

Interval of test is very important too.

Good evening bro

Pls I need your input

I have a system with 2pcs of 180w panel connected in parallel, pwm controller. Before now, I do get 12A & above during peak period but during the raining time it drop drastically. Now, during the harmattan season, I experienced a drop in the current but voltage is high. I am posting this message around past 6 and voltage still as high as 17v but current is 0. In the morning around past 9, current is 4a and above but in the afternoon around past 3 when I checked the current stood at 3.6a & above

Pls could it be that one of the panel is faulty or the heat is making it difficult for the panel to generate enough current? The system is just 2yrs+

Note: There's a gap between the panel and roof because I use rail

Thanks

I done they wait your review on this since that day you posted it.. Nice one chief....

oga i no be jjc when is come to alaba... I brought the mPpt for tasha energy they are very big company in Alaba, abuja. port harcout....you can google them and visit there site...i did not buy for alaba boiz ....the controller is mppt..and i brought it directly from company at 55k...i have pwd too so i know what am saying....just test your mppt with one panel and tell me the reading

i will appreciate if you can give me the powmr mppt to confirm if this mppt is okay...like i said am using one 200w panel for now and am getting 2.6A from the mppt..when the panel is giving 6A via multimeter and my pwd is giving 6A too but i dont know my mppt is giving lower ampere in of more AMPERE

If you are on a tight budget and need an inverter that can carry significant household appliances, then you should consider our Easun 3000w Pure sine wave inverter

Price: 100,000naira

Features:

- Truly pure sine wave. No humming sound from your devices

- Consumes little (around 7w) to power itself from your batteries, leaving you more juice to power your main load (appliances), hence more backup time from your batteries

- Can power significant household loads like refrigerators/deep freezers, microwave, blender, toasting machine, and occasional heavy loads (like pressing iron, 1hp pumping machine and inductive cooker, rated 1100w and lower). Just make sure your batteries can support the significant load consumption from these appliances

- Inverter can be easily repaired; we have a dedicated technician for its repairs and we stock the critical parts to ensure swift repairs. To further minimise downtime hours, we can swap out a faulty inverter for a working one immediately. Terms and Conditions apply

Jefferyzz:
I coupled my cells with jk BMS and what you mentioned is true. At times my BMS will read 99% and 30a plus will still be charging the battery with 0.006 cell voltage difference. Just like you mentioned, users need to pay attention to pack voltage not just the battery percentage especially when one of those cells don't trigger the BMS HVD which will recalibrate the BMS. I didn't use jbd long enough to know if that's same with them. Jbd or Daly users should let us know if they experience such.

Jbd is worse. It's SOC drifts almost every time even with proper charging.
JK is far better bms.
