Hello great people, I’ve been following this thread all through these past months, and I must admit that I have learnt a lot. Please I have a serious and interesting question on an observation :
I have 2 charge controllers, MPPT and PWM

With MPPT @ 12:30pm with few loads on it
Panel output:182.6Watts
The battery voltage indicator reads 13.4Volts but the MPPT controller is reading 14.9Volts suggesting that it understands that the battery is full. But this is not the case. So it reduces the power coming in from my panel and keeps that voltage without any addition for about an hour which is not normal.


With PWM and with the same loads on it
Panel output: 203.52Watts
The battery voltage indicator reads exactly the same as that of the PWM controller and in just about 15-20mins it takes my battery voltage from 13.4V to 14.6V meaning it’s charged to full capacity with the PWM.

Please what could be ascertained from this test pls?
Thanks in anticipation

Abeg this valto metal battery cases dey safe so?

dbshaywhy:
To God be the glory, I finally switch to the lifepo4 battery user after 2 years of planning. I now enjoy uninterrupted power supply, run appliances simultaneously (no heavy appliances). Am very sure Nepa self go dey vex on me by now... Still having 120+ units on my prepaid since month of October.

ManAdii:
Good day.
Does anyone has any contact for importing LFP cells from china?

RickyM:
What are the consequences of not reaching its nominal voltage?
Let’s say the voltage supply from PV is 200V.

BigDickProblems:
My question is still valid. Except you don’t even have an idea on the device you are trying to sell.

dollarnaira:
I don laff taya.

BigDickProblems:
Sorry o, but it seems the name “5000 watts” is misleading. Is that the power rating of the Energy saving device or is that the max Power of any device to be connected?

If it’s not the power rating of the Energy saving device, then what is its power rating?

SaintUlot:
Are you using an inverter, prepaid meter or Generator and you want to save your energy consumption by as much as 25% - 50%? then this 5000w energy saving appliance is for someone like you.

This energy saving appliance will reduce your power consumption on your pumping machine, big ox fan, hot plate, induction cooker, pressing iron and other power hungry appliances. This energy Saving appliance could make your inverter or Generator power some power hungry appliances it couldn't power before now.

Capacity - 5000w
Price - 90k
Call/WhatsApp - 08035537864 if you need it.

Ferdiwar:
I use some power tools (excluding the circular saw) and the are all cordless and so far I'll say that the wired ones are way better as they are more powerful and packs more torque.

For commercial use get a wired one and set up the inverter as intended.

3kva to 5kva inverter will handle it well.

Size the battery and panels based on your need.

leTrizzle:
Could you please explain further?

I am on a tight budget. My budget can only cater for tubular batteries for now

HeavenlyBang:
Right now he comes across as someone who has zero understanding of electrical systems. Just learnt how to install solar components and thinks that makes him a guru.

I've not seen someone who puts out as much bad information as this guy.

Tonididdyx:
Yo!
You're wrong brof...I tried to sell it and guess what, I sold each for 10k ... I mean 10k Naira per panel after I kept increasing and increasing my asking price, something In me told me it's hot cake to em!
I had to sell only two and leave the rest as I felt I was being cheated sef.
I think there's some silverish material underneath the glass if you look closer.

OgogoroFreak:
SRNE or Growatt, which is better?

Rhaspody:
Is wilion a good inverter compared to srne?

Azertise:
Guys, please which websites/app can I use for dollar transactions?

Olamak1:
Multiple declined transactions must have occurred on the card, hence the termination.
Bitnob will never revoke card without prior warning.

Ifeanyi4491:
thst i wanted to make a payment that is above what on my account

Ifeanyi4491:
I have 11.4usd forsale at my bitnob wallet

Bitnob virtual card doesn't work on aliexpress??

HeavenlyBang:
How do I clean my panels?

I've tried hosing them with a some dish soap and water, then just water, but there remains a thin layer of dust/grime on them.

Not sure how much that affects my output, though, but I want them as clean as possible. Do I try using hot water?

ask4bk:
Solar Charger watt output are not calculated with panel volts but with charging volts.
On a 12v system, if it's charging with 13.5 it'll be 13.5v x amps to get the watts entering battery. Same for 24 and 48v. So 3300w on a 48v charging at 53.0v will have amps of 3300/53 = 62amps

Solar volts displayed are just what is coming from solar before conversion by MPPT

🤣🤣🤣

Alexta01:
Hey guys , any affordable solar that can handle charging 200+ phones?

twosquare:
So, update:

The kind stunt I pull on okada yesterday, I no fit do am again. I still blame the delivery guys though.

Tucode:
Hello guys, my 15kwh felicity lithium battery is charging slowly. The first guy that did the connection, did a wrong connection and got my 10kva inverter burnt. I got another inverter (SMS 10.2KW Hybrid inverter) and the new installer corrected the previous connection. But I noticed that the battery now charges slowly despite having high PV from the panels. I’m getting 3.200Watts from the panels but the charging current is 13Amps. I used to see up to 80Amps from similar PV in the previous connection and the battery will be fully charged before 3pm during peak sunlight. But now, even with this scorching sun and without using the battery at all, I barely get 2 bars full by end of day. There’s obviously something wrong with this current connection and the guy is telling me that the BMS in the battery might be bad. I am finding it difficult to believe that. Please any idea what could be wrong? From the little I have read and understand, charging current (amps) also determines how fast a battery charges and I’m see low amperage since this connection.

In Abuja I paid for 10 and got it delivered to my home next day.
If they delay for people then it's something to worry about.
