What you are quoting is less than the stupid quotation I am getting. Kai!!! What of the price of a 10kwh lithium iron phosphate battery? I need a very solid OEM for the vendor. My fear of lithium is the fire risk.

Calm down,lol.

An installer will usually mark up his quote to handle little price fluctuations,and make some more buck from the purchase aswell.

Plus when you buy equipment yourself, you know that if anything happens your installer won't be as committed to helping you resolve it as when he handles everything...i'ld advise you negotiate with your installer. Especially if this isn't your specialty.

Good evening to great Nairalanders🫡🫡🫡
Please I need y’all opinion on this‼️‼️
Does any of these PWM charge controller good for charging LiFePO4 battery?
Or any other suggestions but not MPPT abeg because man no guide 😂😂😂

The 60a of the middle one shown, says it is lithium compatible in the manual, although I am yet to test it.

However, I used it for an experimental connection and was surprised to see it had a functioning over current protection. Ideally a PWM self destructs once you cross it's rated max input current rating.

The LG Dual Inverter does not have this display, but is can be chilling @ 16°C with less than 600w power depending on the AC capacity and the ambient temperature.
From my battery monitor, after turning off the pv input, my 1.5hp dual inverter AC was turned on @ 16°C with the existing loads of 206w at 4:06pm. The power consumption rises to 1,057w at 4:11pm before dropping to 460w at 4:18pm maintaining the cooling.
The consumption used to be higher than this when the ambient temperature is higher. Apart from the actual power consumption of the AC, the ambient temperature also affect the consumption.

Is your battery monitor a victron equipment?

Anyone knows any 1.5kva hybrid inverter with Mppt controller I can get asap.

Please recommend!!

Can I connect more panels to charge faster with solar?

Is the inverter pure sine wave output?

Does that 10w fan blow well, it looks like it's really low wattage

RickyM:
He uploaded a 10kwh battery and I said I want half of that and he gave me a quote for it and I paid. Afterwards I also paid for inverter and solar panels differently so when I said over a million, that’s just for the battery alone.
I paid since last year and during this time even Felicity supposed 5kwh battery is at least able to supply 4.3kw and it’s sold below the price I paid for the DIY at that time before the dollar started rising and prices of things skyrocketed.
Regardless of the efficiency of the inverter and power loss due to heat, 4.3kw that Felicity battery supplied will run a 110W three start rated freezer for more than 24hrs without recharging so yes it’s nothing impossible if he did what we agreed on…Thanks!

Ok

I will contact you

Hmmmm...to run freezers at night, 1m+? How was that supposed to be possible?

These are some of the issues...

mctfopt:
In the bid to make a quick buck, some installers end up lying and delivering substandard products to their client making many assume RE is not ok. Just here to tell any newbie that RE works when done right.

Conversely, when some of us give cost to a quality installation clients will negotiate craze commot for the thing, or simply ignore you and say your price is too high.

I do installations on the side, and trust me if it was my daily hustle, hunger for don wound me and my family... meanwhile, some installers that don't do due diligence when installing are already counting hundreds of installations done YtD.

Exactly my guess, You are only using 3 panels.. all these while..
A PWM controller provides your batteries with the maximum available current, wasting excess Voltage.
So you connected 60V 24.6A to a PWM. Even in full Sun, it will supply your batteries with 28V at 24.6A. excess voltages or 3 extra panels wasted.

But if you do it all in Parallel. You will have 30.8V at 49.2A input and your batteries will charge at 28V at 49.2A.
Here you are pushing too much current, you need High Guage Wires, which is expensive!

With MPPT, you can maintain the 2 in series and 3 set in parallel.
With MPPT, you are receiving the same 60V 24.6A.. your batteries will receive 28V at about 49.2A.. because MPPT will converter excess Voltage to current.


2. When you say MPPTs are expensive.. and you are only getting 840 watts from a possible 1680w..?
You can use PWM. But connect it properly and size the cable properly too.

When I was using a PWM Controller on 24V system, I purposely Bought 280W panels with 30V VMP... and a higher current.
Because I understand how to optimize each Device wether PWM or MPPT. it's all about understanding.

3. Yes, 30.8VMP is the sweet spot for 24V if you are using PWM.

Spot on

Olumighty123:
Yes. It's still available, the issue is with the output

Like what's the issue with the output? Is it not working, does it fluctuate, what exactly.

EduTechTainMent:
You mean you exceeded the maximum wattage rating for the cc?

In his case with a 60A cc, the maximum PV wattage supported should be (12V * 60A) 720w. His installer fed the cc with (180 * 6) 1080w from the panels.

Is the cc a pwm or mppt?

Those panels can't output 60amps, if it was connected more than the max input volt of the CC, the equipment would have burnt out or self protected and not worked at all.

Olumighty123:
I have one 2.5kva 24v. But has an output issue

What's the issue? SA?

dollarnaira:
Not the 60A, but the capacity of a 12v system.
Almost all charger controllers at 12v(one battery) of any amp of charger controller CANNOT DO ABOVE 700w. Your total wattage from the panels exceed what the cc can take. You are feeding the cc with 1080w (6×180w) instead of max of 700w. Check the label at the back of the cc as the info is there.

I don't think this is correct.

I have fed 1.25kwp to this controller but a 30A model. The current stays withing the CC rating and Voc is about 31V_system is still working, no issues.

Queed:
Most of the 'inverter' termed devices (inverter fridge, watching machine etc) are typically switching power designed (aka SMPS), and a properly designed SMPS, built to handle above 100W should have active power factor correction ( PFC ) built into the design.

In the absence of this PFC, the load (your inverter AC in this case) would affect the phase relationship of the inverter output, consequently affecting any meter equipment that depends on the standard current/voltage relationship to produce correct values.

Also, Normal AC, fridge, washing machine general affect power factor, hence I suspect your meter to be the problem here, it seems to be unable to measure the correct power.

Interesting angle..you seem knowledgeable about this stuff. Nice.

However, wouldn't PF come into play when one is considering conversion from apparent power to real power? Because in my measurements, I'm comparing volt-amperes with volt-amperes.

We need to talk, I need to cure my curiosity to know how this remote setup is done DIY. Can you drop your Whatsapp digits please?

balogunsam:
please help. Someone installed this mppt charge controller for my mum and it has burnt twice at this same point (where wires from the solar panels connect to the charge controller).
Happened first time, he replaced it and it happened again. He was about collecting money from her to buy another one again but this time she reached out to me.

It’s a 12v 1kw inverter system with 6x 180w solar panels and 200ah battery. She uses it at her store for a small fridge, a desktop computer and fan.

Is this a problem with the power from the solar panels being too much? Or the charge controller is thrash?

Please help. Any insight appreciated.

I've used that controller before. Provided the amps of the panels does not exceed the controller specs, then the installer used a fake copper cable that is heating up and damaging it, an undersized gauge with the same heat issues, or he is not screwing the cable properly in place, partial contact which can still cause same heating issue.

A proper installation might cost too much for him.

Hmmmm...

easyyoke:
Anybody please? Or all Charge controllers sold in Nigeria, none of them get bluetooth app?🥺

Victron smart controller has Bluetooth feature.

Obnoxious2001:
How did you do the test?

Measured voltage and current with a clampmetre at constant load. Both AC side and then DC side.

gifted65:
I paid o, the job is dirty. So what do you suggest I do though i like 12v because of low cost

Where is your location?

gifted65:
Please I need help.

I have 300 (3) and 250 (1) solar panels
100 lead acid battery (2)
Inverter 3000w sachet

Because of my 12v, so the the installer add another pwm cc to the existing powr mppt because he said the mppt could only take 3 panels.

Plus that inverter looks like a modified square wave type. If true, be saving cash somewhere to replace fridge compressor, buy new fans, and maybe repair TV.
During the day, i still don't have sufficient energy to power 120w freezer and two ceiling fans with 2 tv

The installer did this for you free?? Why are cables flying everywhere?

Meanwhile your system is too small for the load you are putting on it.

sharks776:
I am actually in the same dilemma, am in dear need of a remote monitoring device for my Felicity set up.
My set:

7.5kv inverter (Felicity)
60a cc (Felicity)
100a cc (Felicity)
60a cc (fangpusun)
12.5kwh x2(wakatek lithium batteries)
10kwh (Felicity lithium battery)

How can I monitor remotely?

I know IVEM Felicity hybrid series have a port and a dongle that you can use to stay in touch with your system remotely.

isangjohnson:
Please, drop it and let's compare with others. I have similar inverters, though from different companies and I'm yet to hook them up for capacity test.

So I did a test today with a victron quattro and got about 61% efficiency. I've done this before though and had to repeat it to be sure I was not making mistakes.

This confirmation led me to do some research and I found this....see pix attached.

Link to full article [url]https://unboundsolar.com/solar-information/inverters-article#:~:text=The%20efficiency%20of%20an%20inverter,when%20running%20very%20small%20loads.[/url]

In summary,these "cheap chinese knockoffs" as some people like to refer to sachet inverters, are not bad at conversion efficiency, and basic protections.

isangjohnson:
Can we see the datasheet of this inverter?

Sachet inverter de get credible data sheet? I'll check
