I think you might be right oo.Wifey says there no light from 11am till I got home around 7p.m yesterday.They pulled through the day because it is connected to 4 units of 260 watts panel. Charge controller was still showing voltage at 25.1volt.I used generator to charge it back to full capacity between 7pm and 11 pm.Surprisingly around 2am my kids came to wake me up that the inverter was making noise?Only 43" inches smart TV,decoder and about 3 lights of total wattage 24 watts was on. I checked voltage in CC it was 22.6volt.I switched of inverter and changed to my second inverter and the voltage on the CC went back to 25.5.I am tired of all these our AGM batteries honestly. I think I will begin to plan for the single 2v batteries like oga George uses or begin to think LifePO4.Using energy at night now is always a challenge.

If you get a multimeter and test the 2 batteries separately, you will observe that their readings are different. Mine started when after full charge, one of the batteries drop to 10V within 2-3 hrs while the other still hovers around 12.4V.

Kindly claim warranty on time before it's too late.

That's serious!No problem.Thanks for the info. I am certainly done with all these our 12volts AGM for good.The only one I ever used without headache was Fullriver and Ritar!

Classic failure mode of l3ad acid batteries.
R3ads correct voltage, but drops rapidly when put on load....

And it even reduces your harvest from solar panels cos its high voltage confuses the CC to think that battery is getting full.. and cc then throttles back harvest

I am planning on buying this pulse charger on jumia, is there anyone using this type on here



.

Y3ah, prefer the smaller foxsur, with a dedicated pulse/repair button.just that its rated for only 100ah batts.outputs only 8amps max on 12v

I have 1 unit of this Charger for sale 16k.
It outputs over 20amps at 12v, and suitable for upto 400ah batts

How much will it cost to construct a solar power for a deep freezer with 150w input?
I'm also thinking of getting a solar freezer entirely, but I'd like to know which is better in the long run.
The freezer will be used commercially.

This calculation/issue has been treated s3verally. How many hours do you want to run the freezer?

Energy is 12v 200ah batt is 2400wh, factoring in losses, efficiency dod, lets assume 1500wh, so dividing through, your freezer will last 10hrs, use same calculation to arrive at qty of batts you need if you want longer runtime on the freezer.

Minimum of 600w solar panel is needed to put back energy taken from battery, personally i prefer 800 to 900w... So multiply this again by the nos of battwries you intend to buy, based on the earlier calculation


Solar freezer uses DC and consumes about 50% less energy for same capacity. Just that its 200% more expensive..

dollarnaira:
@omotoda
What is the capacity of 1st and 2nd inverter?

1st Inverter is Luminous 1.5kva Zelios 24volt (Powers lights and TV),:second Inverter is Genus 2.5kva 36 volts ( mainly for freezer,fridge ,ox standing fan)

Senior man, thanks.
This type of calculations are not my thing
10hrs runtime is more than enough.
Can you please, give me an estimate of what I'm going to spend?

I woyld advice you get 4x 300 watts solar panel
1.5kva 12volts inverter
One unit 12volts 200ah battery. 2 units of 40amps pwm charge controller.. If your budget is tight.

However 2 batts would be prefferred with 6 x 300watts solar panels, 1.5kva 24v inverter, 60amps mppt charge controller.

Engage or scroll through th3 posts of some of the vendors here to confirm th3 cost for each component listed.

So after a lot of back and forth,
Am back to this lifepo4 group buy matter.

Due to less than stellar performance from several china shippers, i have tried.
Am considering the safer option of the alibaba seller handling the shipping.
He says his minimum cargo is 1cbm which is 64 pieces of Lishen 3.2v 272ah batts, cost about $550 customs and all inclusive, and pick up in their lagos warehouse. I only need 32 pieces, hence looking for possible buyers of the other 32 cells.

Each cell is about $80, and shipping duration is 3 to 4 months

The chinese new yr holidays is coming, commercial activities in china will grind to a halt from early feb and pick up again early march

If the price is is right, I'll buy.

I am curious to know how the two 40amps PWM controllers will be connected to the battery.

Will all 4 panels pass through the two controllers or will it be split into 2 panels per controller?

Does that combination give a better harvest than a single 80amps Pwm controller for instance.

Modified: Never mind, I forgot to account for the max solar input of the 40amps controller. It can't take all 4 (1200w) at once so it has to be split.

Hello sir,

I actually wanted to mention you here last week about the group purchase, but events overtook me.

I am imagining that I would need 4 cells to make a 12v system, right?

What is the cost of the shipping itself? Also, can we get that brand Oga Oje.sky got with Va.lto?

I am interested in getting at least 4 cells, and funds will be available by monthend. Can we create a group WhatsApp for it?

Eve is the brand Ojesky got b4, unfortunately its out of stock, few sellers who have it are selling $84 per unit 280ah Eve cell. The Lishen is as good as the Eve cells and with the high demand and scarcity, the available eve cells now may be a mix of good and poor cells

Shipping cost i also wrote there abt $550 for 64 cells,

Cell prices hv gone up by about $10 since that time i wanted to do a group by. Then with this chinese holidays coming up. Its best the orders leave china b4 it starts, if not it will extend the already long shipping window

@eleojo, good you spotted out y i recomm3nded 2 units 40amps pwm.
80amps pwm isnt common, and would have served.
But i think its not that common and maybe expensive, i hv never seen it b4

80amps and even 100amps is available on Ali but he may not have enough time on his hands to afford the long wait.

so sorry about that. There are better batteries in the market. Luminous have always been a no go area for quite a while. The good ones are pricey and you won't find them lesser than 145k per unit or thereabout. Buy from genuine suppliers too as there are many replicas too. I ditched luminous a long time ago, should be over 4 yrs if I remember correctly.
I don't have issues with my AGM's.

The CBM rate is high at $550. But it's all good if it comes with buyer protection. Some Nigerian shipper can ship for less but with ZERO buyer protection. Lishen, EVE are all the same, especially as most of them are grade B cells (grade A sells for around $195 per cell, but the truth is there is no sure way to verify if it is grade A or just packaged grade B unless you are in China and was able to visit the company). But their capacity (272 or 280) is never in doubt. What is the name of this store at Alibaba?

Shezen basen.
550 is inclusive or clearing, yeah, its a bit high, but with the added alibaba protection of shipping, thats why am considering it.

All these naija china shippers, if anything happens to your cargo.. OYO, nuthing for you.
Last month over 350 containers fell into the north sea ... During to a terrific storm that blew them off 2 ships, 1 week apart.
Am sure if it was nigeria bound cargo.. compensation might not be paid to small importer s like us with 1 or 2 cbm.
All the trusted alibaba lifepo4 s3llers i know/contacted dont ship to nigeria directly

Yeah, have researched throughly, the lishen is as good as Eve.

My major headache is the exchange rate, i would have considered going solo and buying up the 64 cells to resell at hansome profit , but what if dollar crashes back to 360 from the present 475? In april or may when the cells arrive, my profit wont be so hansome again..considering the huge funds tied down

Then lifepo4 cell prices are projected to go up afyer the CNY holidays, Eve major sellers has even released official statement that new model eve cells will be sold for 110usd early this yr
