AkoEja:
I am looking to purchase/upgrade to a Lithium battery pack preferably Pylontech or Weco.
BYD is preferred actually but it's a bit more expensive.
Between 7.5 to 12.5 kwh depending on price
The battery will go with a Victron multiplex(already owned)
Will also need a good MPPT charge controller 60 A and Victron colour control GX
Can anyone supply this?
Need this asap
I am based in Amuwo , Lagos

earthrealm:


so we are about wrapping up this group buy, , i am impressed by the turnout, we have about 140 cells being demanded for, our target is 190 cells, so now is the time for interested folk to join.. options are available for people who dont want to pay full money

saint2ace:



Am interested pls add 0806742-3970

I have a 24v serup, 4 pieces of 12v 200ah battery connected in 2s2p, i noticed that runtime has reduced much, used a volt meter to test the natteries this morning,
1 leg of each parallel bank read 10.3v, while the other leg was 12.4v.
Am thinking of rearranging the batts, and using busbar,
Is putting the 2 batts of similar voltage help ?.
Ie form 1 string with the 2 batts reading 12.4volts and amother string with the batts reading 10.3volts and then parallel them, or should i leave them the way they are?

In theory this should work but real life is another matter.

Splitting the bank and adding up matched batteries in series then using a bus bar to place them in parallel should enable the stronger batteries discharge into the weak ones and ultimately balance out.

The issue is that the batteries at 10.3v may have lost capacity and no magic arrangment can fix that.

What you need to do is isolate the two batteries at 10.3v, charge them fully and discharge them and charge back a few times then test their capacity - if capacity matched with the stronger batteries then you can use your bus bar arrangement going forward.

Worst case you have two decent batteries and two scrap which have some salvage value.

If the weak batteries at 10.3v have lost capacity relative to the other two at 12.4v then do not add them back else they may kill off the remaining two good batteries.

Big Shoutout to the Bosses in the house.

As my Monicker implies, I am a rookie with "chikini" background in renewable energy.

I recently moved into a remote area and got some tier 4 600 watts mono panels for myself (150 x 4) for a 12 volts setup. I also got a 50 amps PWM charge controller and 10m cable dual core cable.

I arranged the photovoltaic array in parallel for more current (A) and positioned for proper exposure to sun radiation. Although I must confess that the distance from the rooftop to the panel isn't up to 5 inches.

Distance from Panel to CC = 8 Meters.

The reason for this post

1. The highest current I have recorded is 16amps (1st week after installation) at maximum voltage.

2. Now I record less than 12 amps even on sunny days.

3. Total AH per day is within 60 - 66ah.

I have installed a similar setup sometime in the past but with a different chinko 60 amps PWM controller and saw 20amps current output. Something is telling me to call my base and ask them to send me 60amps PWM (That brand i used in the past) but i feel its going to be a wasted effort.

I know you all will say "Buy MPPT", I will buy one by the end of the month for checks but please recommend between EpEver, PowMr and MakeSlyblue.

Expert suggestions will be appreciated.

Thanks, its a remote offgrid setup, wont be available to do the charge and recharge issh.
Bank is almost 5yrs old, flooded tubular, so want to squueze the last ounce of life from them. Will arrange the 2 reading 12volts and above to form1 bank, and the bad ones, another bank. With the busbar.it would be easy for me to take offline any weak string.


@Iygeal, yeah at balancers, at time of install, not so common, and from experience fla dont really need Balancer s.
I have a desulphator hooked up at install

Flooded tubular battery all the way! Just get original product and you are good to go.

omotoda:


Tubular get maintenance wahala jooo.You have to put them in well ventilated place again!!!

The issue is not buying from Alaba but getting the authentic product.

Like @kiekie posted sometime back, you see the blue Luminous flooding Alaba, but Luminous company in Nigeria doesn't sell it.The only SMF they have is K- Star which they haven't had new stocks for months now.They now sell mainly tubular battery.

As at my last call few weeks back,the new Luminous NGRT battery goes for 164k.

Go few threads back and see the price our Alaba people are quoting.



For Index battery,there is a company in Ilupeju ,Lagos,Multi power,the bring in Index battery.They are the manufacturers of Mpower, and Multi power brand of inverter and batteries.

I called some weeks back and they just got their stock.Index SMF goes for 125k.

For Amaron,there is also a company, D2H Ltd ,that sells Amaron Quanta battery.Also in Ilupeju.

Just google the names,you will get the address and contact of these companies.

For Luminous,Simba Industries have offices in Ericmoore in Surulere,Ikeja and Oregun.

For Haustrom products( Glow Energy,Microtek,GSRinverters and batteries), their office is at Fatai Atere Way,Mushin,beside STARTIMES OFFICE).

I haven't been able to figure our for Ritar but I personally will not buy those known brands of batteries from Alaba. I have had my share of bitter experience too which made me go directly to the companies that will honour their warranty.

For the regular cheapoo 70k,80k batteries,you can go to Alaba but be ready to buy another battery 8 months down the line.

If you cannot buy from the companies because of logistics issue,then you can try out some of the sellers here.I am not promoting anyone in particular but @kiekie is someone I have dealt with on 2 different occasions and had no issues.His price might be a bit high but based on my past experiences with him he is straight forward. He might also sound a bit arrogant but its something some of us can overlook as the price to pay for quality in an environment where honesty has become gold

odimbannamdi:


This battery thing is very dicey, hence I will speak only about what i know - the emboldened.

How do we reconcile this direct experience:

Last December, when Luminous began their battery swap promo, i reached out to one of their accredited distributors featured on their very own website and, after showing me proofs of his distributorship with Luminous and even awards he has won from them, quoted 114k as the price he sells his Luminous Tubular NRGT series.

In fact, he said they were doing a promo and that prices will return to 120k by January 20th. Around this same time, official price of the same battery was about 140k on Luminous' website.

What are your thoughts?

Good afternoon house, regards to all the bosses in the house, please, does anyone has this buck converter 20Amps, 300 watt or 30Amps 400watt for sale ? And also this Ceepro 600watt pure sine wave inverter?

Saipro:

Discount/rebate for distributors

omotoda:


Thank you. Most companies discourage direct sales to end users in order to create market for distributors. If everybody goes to the company ton buy then how will the distributors ,who are the ones promoting the company's brand make money?.So they hike the price while they give discount to distributors. It is the same logic with airlines. You can actually get flight rates cheaper from the travel agents that the airline itself!

ojeysky:
I just saw this, looks like it's going to be a sunny week, but men prime is a good panel. It did 8w during the night

Solarrookie:


Thank you King!

EPEver is premium but have you used PowMr?

I saw videos with some people saying that the Charge controller is less efficient and the 60A is actually 40A.

It's cheap though.

Ojeysky, I sight you!

Those who "claim not to be pros but we know them" might hate me for saying this (as it's something anyone who's done reasonable research should know, long-time installers know and copycats might know with this post) but ... you should by now have realised Canadian Solar modules aren't made in Canada.
