Do you hv a dedicated china shipping thread?
Kindly post same, i checked some of your your previous posts, didnt see.

Back from another unnecessary ban.
See what i posted to ojeskys challenge then, seems it still didnt work as well..
now tell me why i was banned??

The reason for the ban is because your sentence was too LONG

cooldipo:
I dont have a thread on that yet maybe i should create one for the purpose of accountability but the way previous thread got taken down has discourage me

Yeah, you need to create a dedicated china shipping thread, to build a stronger presence and credibility, your website is for powerbanks, nothing about china shipping there.

Anybody that has transacted succesfully with cooldipo or can vouch for him, should pls come and tell us

I have a question that needs answering?

The expected number of panels to charge a 200Ah battery is 4 panels of 150w (correct Me if I am wrong?)

But that's not my question... My question is if I only repeatedly daily use only 150ah of a 200ah battery... Is it OK for 3 panels of 150w to charge the battery?

Your PV Harvest will fluctuate with seasons, cloud cover etc. If you can afford the 4 modules please go ahead. You can't go wrong with adequate number of PV modules for your system.

You are already past 50% DOD of the battery if you use 150a out of a 200ah battery. 600w panels is your best bet

A typical lead acid battery will die a very early death if you regularly use 75% of the stored energy - this is what 150Ah out of 200Ah means.

Under favorable conditions, 600w of panels MAY produce enough energy to fully recharge a single 12v 200Ah battery especially if not depleted beyond 50% - In practice, we size the panels based on combined KwH of energy to be restored into battery and used for running loads during solar hours. So you may find you need 900w or more of panels per 12v 200Ah battery depending on what your day time loads are.

I would not use 150w panels except I got them for free - there is a lot more headroom and typically better price to capacity and installed foot print ratio for the larger (say 300w and bigger) panels.

I have done business with him (cooldipo) some years ago when he was using the moniker "Alejob and Alejobs". I ordered some power banks as a souvenir and he delivered. He might not recall but he is an honest fellow unless Nigeria changed him. His Name then was "Agbaje Oladipo Adeyeye" and he banks with GTB.

I am not encouraging you to do business with him, i am only sharing my experience with him.

He used to have a thread where he promotes his business.

Cheers

I am only a procurement agent. I don't own a shipping company yet but I use the service of a reputable and responsive shipping company.

MY brother, this is what am saying in a nutshell .
people make purchases of several hundred thousands, or millions, as a procurement outfit, the buyer will have to entrust you with his cash..and hopes you deliver within agreed timeframes. its not easy for,king out such cash to a faceless stranger on the web, having a thread, where one can see your previous transactions and reviews will give potential clients a certain level of comfort.

like the thread below, i transacted severally with the guy after going through his thread, same procurement biz, as you

150ah out of 200ah battery is too much to take out from a battery...unless you are replenishing such concurrently.
would recommend, a panel design that would carry this 150ah multiplied by 2, is 300ah @ 12v is 3600 watts. 3600 watts divided by 4hrs implies you need 900 watts panel to have a well designed system, if you are offgrid.

however be aware that if you have smf battery, and you fail to run your loads concurrently, on a sunny day you would have over 60amps flowing to the battery, this will kill the average single 12v 200ah smf battery quickly, within 6 months

hi thanks, this is the battery in question. It's actually a 220ah

Very important to note!

I am beginning to hv some doubts.
How did u arrive at this 150ah daily consumption?.
The 800wh, u now posted is daily solar harvest or consumption?.

Play it safe, get 600watts total panel array and call it a day.
I dont think you hv the necessary know how to handle 900w array...2ndly @ 12v, max most 60amps cc can handle is 720w

Ok thanks
Yes 800wh is my daily consumption.

If I'm to answer this. SPD is not connected the way you are thinking it should. I have queried why that is so severally but have been made to see reason its in its operation. You will require dedicated bussbars for this your SPD.

While the "In" is connected to the positive bussbar with the other panels positives the "Out" is connected to the negative buss. Definitely you choose one or loop both PE for your ground.

Still confused? Look at the attached pix for the normal wiring of a combiner box. Hope this helps.

A Ryobi tool in the picture. Pretty amusing. My batteries keep dying on me and the chargers are long dead. How do you charge yours?

Thats not mine bro. Picture was snapshot from a combiner box video. Why not just get another charger?

Good morning guys, please I have 150ah agm battery I have been using with 2 180watts solar panels,is it compulsory I increase the panels to 600watts.my charge controller is 30a

If the current solar panels solves your energy needs, then there is no need to upgrade.

Got 2 replacements asides the initial 2. Inverter even set to 60Hz. Same fate. Currently use a Imax to charge them though kinda cumbersome. The tools are great but the battery pack are meh

[quote author=DUI post=91352073]Good day colleagues on NL. I am new to this thread and have been impressed with the comments I have read so far. It is amazing to read so much technical information coming from so many people in just one place. Please I need assistance from the gurus.

I am trying to replace my inverter batteries and also install solar panels in my home. I need information on where to get access to good quality 12v 200ah solar batteries and 300 or 400 w panels in Abuja and do not want to fall into the wrong hands. If you can assist, please provide information in this order: type, price and location of store and finally phone number.[/quote

Good afternoon good people
Please, can this freezer be powered by a 600w pure sine wave inverter?

Use same I think initial surge is above 600w. If your inverter can overload for some secs you are good to go

Thanks boss, pls do you use yours with your inverter? And if yes, which kind of inverter is it?

Many times we end up with 150 watts panels because our inverter is 12v. Others are 24v.

I feel 4 panels would be better if it can be afforded at least it'll take care if you over drain+ cloudy days and stuff

You don't have to end up with 150watts panels because your system is 12V... It all depends on how flexible your CC is.

My system is 12V using 2×260watts panels in parallel... That's the beauty of MPPT
