LifePo4 Cells are my best suggestion for you.
there is a Man on this thread @Valto, who can couple genuine Cells for you.

thank you so much sir. Any other good options apart from LifePo4? Thanks.

dammodee911:

Recently installed a 5.5kwh Smk hybrid on and off grid inverter system coupled with 4 units of 12v 200ah blue carbon lithium ion lifepo4 batteries and 8 450watts mono solar panels. Everything seems fine, but the only downside is that my 9kva firman 12990esr generator can’t seem to charge it. So far only the solar and Nepa light have been able to charge it. But with the raining season on full mode and epileptic power supply, I really need the generator option. My installer said my generator frequency isn’t enough, this is a generator that comfortably powers my 3hp inverter standing AC and 1.5hp inverter AC. What can I do pls? So far from the inverter screen, my gen produces btw 275 -285v and btw 48 - 50.5hz. Shouldn’t this be enough to charge the battery?

Why is your gen producing such high voltage?!... And an installer that tells your your gen isn't "producing enough frequency" without checking your gen frequency? I doubt the competence of such an installer tbh.

I think your generator should not exceed 240v, check the input voltage range of your inverter. The frequency of the gen looks ok to me.

If you look at the sticker pasted on the panel you'll notice rough cut at the edges, thats to show the panel is not Genuine Canadian Solar

gadgetplanetng:
Who sells original panels?

@Valto suggested Auxano and they say no stock

& and attached image is the type I'm seeing which I won't buy.

That is not a genuine Canadian solar. Its rebranded

At this moment, that is the best option l can recommend to another person and it is what l also use.
You can also read reviews of others on this thread, to help you make up your mind.

sethtsadopp:


Thanks for your response, I understand your point. But I have done some research online and from all I could gather, the Jinko Tiger Pro series is actually either at par or even slightly better in performance and quality as Canadian solar.

https://lightningsolar.com.au/canadian-vs-jinko-solar-panels/

This is one out of many review I saw doing comparisons. Jinko appears to have come a long way. I believe the Tiger Pro series has an efficiency of 21.4% which is great.

No worries, Your Money, Your Choice!
All the best Sir.

Thank you

Thanks for this info,
I might not be able to speak on the rest,
But AC, that calculation for inverter is misleading,

Let me elaborate abit,
An inverter and regular AC uses exactly same wattage no different 1 HP is 1 HP in terms of power.

Now the advantages of inverter over regular AC
1. No High/surge starting current.
2. DC compressor meaning you can reduce speed = reduce power consumption.
3. Can work with low voltage.


So in the real sense in terms of power, you are not really saving anything with inverter AC Just saving the your inverter from surge startup.

That's because, if it takes 5 hours to cool a room with 2 HP AC, your inverter can cool it in like 4- 4.5 hours but consumption is still the same.
And when you engage energy saving. Lol, it's like slowing your can from 100mph to 50mph,
You will get to your destination but at a longer time doesn't mean you have save fuel. Same goes with inverter AC when you engage energy saving on a 2HP Ac you just turn it to 1.5HP or 1HP.
Meaning if 2HP cool in 5 hours, 1HP would be 10+ hours.

So has energy being saved?

durodee:

You've identified the problem partway. The voltage of the gen is too high for starters . My experience is that some inverters will not use any power source that the voltage is unstable, above 250v or frequency less than 45Hz . You can attempt changing the gen's AVR and see

Thank you for your submission. I will take that into consideration and have a new AVR tested to see. Actually I have two generator, the older one which is a 5kva king craft is the one producing such high voltage of about 275v. My new firman produces btw 223v - 225v but still isn’t charging. I suspect the inverter probably needs some setting

Thank you. Will try the. AVR option

mctfopt:


The output frequency of your generator appear to be ok. But isn't 275v to 285v too high? Most over voltage cut off devices will cut off voltages above 242v.

I think your generator's output voltage is too high and may be the reason the inverter cannot charge on gen use.

Consider either fixing the generator's high voltage or getting an AVR. But I think the latter is not really a cost effective fix.

Thanks for your feedback. I did try the suggestion of loading the gen but still didn’t fix the issue. Tomorrow will get a new AVR to test it with, hopefully that would fix it.

And yes my installer introduced me to the blue carbon lithium lifepo4 batteries, researched about it online and read some good stuff about it. It’s been barely a week, so I haven’t really tested it’s depth and efficiency, barely even had opportunity to charge it enough. No light and it’s been raining back to back. But will be sure to drop a feedback once I get the gen issue sorted hopefully. Thanks

ojeysky:


I will also look at the generator voltage again, you may also try to apply other loads on the Gen and then see if your inverter starts charging. Try a lower charge rate as well.
That said, will like feedback on this bluecarbon, I see you have 4 so each is 200ah 48v? and you have them in parallel or they are 200ah 12v each and you have them in series?

Thanks for your feedback. The input voltage range on the inverter label says 50/60hz I suppose

Trippledots:


Why is your gen producing such high voltage?!... And an installer that tells your your gen isn't "producing enough frequency" without checking your gen frequency? I doubt the competence of such an installer tbh.

I think your generator should not exceed 240v, check the input voltage range of your inverter. The frequency of the gen looks ok to me.

hello,
What will 300k be able to setup if i have a working old PRAG 2KVA - 24Volts. Location Abuja. Needed vey urgently.
and what type of battery are now best for solar/inverters?
Advice needed.
Thanks.

1. 300k will give you 2 tubular battery at 250k or 260k. To be charged with Grid supplies (NEPA)
Or if you can up your budget by 235k will give you ;
Batteries X 2, 600w or 640w solar panels( though not sufficient but at least for a start), 60A charge controller and cables for the installation.
2. Best batteries are lithium batteries but mostly expensive at the initial cost but pays in the long run.

Hello house,

I purchased a PowMr 60A MPPT CC barely two months ago for my parents setup, unfortunately they called me that the display stopped working and they are not able to ascertain if the batteries are charging. Their installer also travelled so he hasnt been able to go take a look. Please any advice on what to do? Or anyone experience such? Thanks

Hi bro,

I am the unofficial distributor of the PowMr 60A MPPT Charge Controller... ...took a break from Nairaland 'coz I was banned by an overzealous mod for 2 weeks...lol

Did you get this from me? Has the issue been resolved? If no, please reach out to me so I can see how to assist you further as I have some solid links to the factory. Come with pics and possibly videos of the item so that I can engage them on your behalf.

Juror:

Had similar experience, the CC was actually still charging but client required visibility so I had to sort out the client with a new CC, I'm expecting a replacement LCD to replace the bad one, hopefully it works.

Funny coincidence. I just watched a Will Prowse You tube bifacial "Signature" brand solar panel review couple of minutes ago and I now see this post, about the first on this thread I think, about bifacial solar panel.

Na the installation go get problem sha. It has to be installed at a much higher level than the average regular panels and placed on a reflective/white surface in order to get the max out of it.

Valto:
i personally use prime 380w panels which is real capacity and performance has been great. get prime 450w from yingli office in alaba/ikeja for around 100k

Hello Valto. Hello @ Ojesky, @ Niyi, @ all.

Just a quick help here.

60A MakeSkyBlue MPPT already hooked to 3s 2p 360watts panels for a 48v system. Readings on the CC approach 35amps on some sun-smiling days.

Now there is intention to add more panels. But apparently original Felicity 360w are scarce in the market, or rather let me say my trusted supplier has ran out of stock. And I honestly don't want to source from another point until such a time he has stocks available, something which seems to be taking forever.

I know other vendors here may have it, but I've over time developed a relationship with my supplier such that he gives "pay later options" on some days, reason I'd still want to stick with him on the Felicity.

Okay so I thought, maybe I can get 3s configs of other higher or lower rated panels in parallel with it, at least I can source for those from my existing supplier or a new honest supplier altogether if the former has no stocks.

So is it allowed to get something like 410w panel in 2s or 300w panel in 3s or 270w panel in 3s and then parallel the string to the pre-existing 3s 360w on the same MPPT CC?

Will that step be a blunder or it isn't considered counterproductive considering that the VoCs from the new proposed strings will differ from the pre-existing strings?

Meaning if 2HP cool in 5 hours, 1HP would be 10+ hours.

So has energy being saved?

Firstly, the surge component of the regular compressor consumes their own fair share of the available power, a disadvantage clearly lacking in inverter devices.

The surges can rate as high as trice to five times the running power. So you can have as high as 3kw for a 1.2kw regular compressor. No matter how transient that surge is, it impacts your battery storage and if you closely monitor your battery while it is both in either inverter device or the regular ones, you'll notice some differences in the backup. You'll notice these differences too if you use municipal power supply where consumption is correctly calculated. But you can also use a smart plug like the Tuya Smart plugs to also calculate these differences.

The inverter devices as you rightly agreed lack that surge/massive draw, hence you save that transient high power consumption.

Secondly, inverter devices aren't just for the name and not just to reduce the power, but for specific scenarios where power wastages will occur. Your regular compressor keeps working at the SAME power rating even when your desired ambient conditions have been attained. That's like keeping your tap running even after your bucket is full. There's no sense in keeping the tap running when the receptacle is full. Worst part is that even though the thermostat regulator kicks in to mimic the working pattern of the inverter counterpart, it still ends up consuming more because of the frequent surge-accompanied startups.

Your inverter device ramps down the speed of the compressor and therefore consumption of power once the desired ambient conditions are achieved. Hence for a closed room where the internal temperature is kept well insulated from the outside warmer temperature, your inverter AC gives you true value for your buck.

Of course, in a situation where you have frequent mix of the internal and external temperature conditions like in frequent opening and closing of the room doors or of the freezer, the compressor appropriately ramps up speed and work to attain/keep the preset ambient conditions, hence inverter or not, it ends up doing as much work as your regular compressor will do, ditto the power consumed.

So is it allowed to get something like 410w panel in 2s or 300w panel in 3s or 270w panel in 3s and then parallel the string to the pre-existing 3s 360w on the same MPPT CC?

Will that step be a blunder or it isn't considered counterproductive considering that the VoCs from the new proposed strings will differ from the pre-existing strings?

If I get you right, you already have 6 units of 360 panels wired in 3s2p and you want to add another? You can do 2s of 410w in Parallel with the existing one because you want to get the voltage as close as possible to the existing strings, but note that this is not an optimal setup.
