It's not my battery that is the issue but the inverter. It's a genius inverter and I mistakenly charged it with a small gen which caused something to burn inside it. So I'm looking for a replacement inverter while I take it for repairs.

Oh my bad. Didn't read it very well. Try a Luminous inverter then.

How I wish you knew why I asked?

However, if I decide quoting prices too, you will be surprised.

No vex. It was a light joke with a tinge of seriousness.

We hope you too will come with challenging prices. Competition is sweet and it's a win win for both vendors and patrons.

This is a seller with a good heart and customer relations but time will tell. What happens when the millions come?

True. I have done some.imoressive deals with him though. Good customer relations and seriousness with follow up until you get your goods.

But I hope to have cashed in thru him well well before he becomes toxic. If our friend becomes toxic, hopefully another fresher will be on stand by.

With 2 Taico balancers and 3 HAO2 attached to my 20 x 200ah batteries purchased at almost 6months intervals. Some of whigh are already 2yrs old but never experienced 50% DOD.

Though I acknowledge lithium is is the new template for us but
For some of us who can't afford lithium at a go will have to make renewable work at our pace using lead acid. It still serves me well with my manual Air conditioner working till day break and a resting voltage around 50.1v

So my brother.

Don't loose faith in balancers.
I only hope you did not allow the terminals touch

@Bolded. Do you mean 20 (twenty) pcs of 200ah?

Now I understand your position that you can't afford lithium at a go. What is the voltage of your system?

The lithium that will replace 20 units of 200 ah at a go, well maybe Buhari will lend you the money sha.

Bro which type is manual air conditioner? Is it power saving?

mcTrinity:


Lollzz... You forgot he stated "at almost 6 months interval"...
Biko, how do you buy Lithium battery package at intervals? Buy the battery modules, then later the box, and later the BMS.... Lwkmd!!!

He is talking about lead acid bank, not lithium.

saint2ace:


I think the sequence should be battery module, BMS and box, am really thinking of buying my battery pack in that sequence. That way it's easier on the pocket.

Or what would you all advise, jejelaye

By the way am thinking of abadoning the box and building a power wall or power box and be getting the batteries lil by lil, I hope the internal resistance won't be a problem for cells of different age and usage?

Look just buy as many cells as you can accumulate (become an accumulator ), then buy the BMS. Don't bother buying case o. Visit your local welder to construct a case for you the size of which will house all your prized cells.

Does the inverter still charge normally after the incident?

It may be that the charging circuit is affected and does not charge your batteries to full capacity again which may explain the short backup from 12hrs to 4hrs.

Also was the change in back up time almost immediate following the spark in the inverter or was it a gradual thingy? The latter may suggest that the battery is either naturally approaching EOL or the poor charging from a bad inverter charging circuit may have had some not too good effects ok the batteries.

House.

Is this inverter good that it can be recommended for someone? I don't want anyone to come and be locking my shirt after 6 months o.

Remember I said 50.1v minimum overnight voltage
Yes - 200ah x 20 or 48kwh as my bank

By Manual air condition i mean old power guzzling shinco ac running @ 1400w

Meanwhile my bank is properly circled on daily basis and leave the rest to my balancers.

Very good inverter, I've been enjoying mine since 2016 in addition to the ipowerplus batteries. Although, I've not yet added solar to my setup but hoping to do so soon

It's a good brand but I think this particular model does not do up to 1kw solar array.

My brand. Using for close to 2 years now no issues. Mppt max is 600w but I've seen people use 1200w and still the unit kept powering. Only problem is it enters float a lil too early [bmv reads 88-90% when it enters float] while my cc enters float at about 98%. Also the constant fan running noise on loads greater than 200w but I've learnt to live with that. This inverter is infamous in South Africa

Yes it was almost immediate drop to about 6 hours but it's now 4 hours.

Are u completely off-grid with your setup and how has your experience been by using the in-built charge controller of your ipowerplus inverter? I am planning to start with 600W panels after this lock-down and gradually increase my panel size with extra charge controller.

No I'm not completely off grid as the compound generator comes on @ night. As for phcn they cut our light for more than a month and my solar panels are sufficient. I don't use the mppt part of the inverter as I didn't want to exceed the max 600w and also I needed a charge controller for battery equalization as I use tubular batteries. I might connect 600w to the inverter in future when my loads increase.

Yes it was almost immediate drop to about 6 hours but it's now 4 hours.

I think the charging circuit/board might have been affected by the surge from the generator, more so since the rest of the inverter works fine.

The board may no longer output adequate charging voltage to the batteries. Your batteries may have therefore been exposed to suboptimal charging for sometime now probably explaining the gradual reduction in backup time.

I assume you are not on solar. So you may need to get a standalone AC charger to charge the batteries pending the time you can have your inverter checked out and this needs to be done before the battery reaches point of no return, if they are still salvageable. The standalone chargers only need to be plugged on the battery terminals along with the inverter wires.

Can an extra MPPT standalone controller be connected in parallel to increase the solar inputs charging the batteries, in case one wants to increase battery capacity?

Does it imply that the in-built controller is only twenty a-m-p?

Is it MPPT?

Hello guys,

I've always maintained here in a novice when it comes to Lithium batteries so I will need the help of experts in the house. There is this guy I follow on YouTube, name David Poz. Kindly watch the video below and help me explain how he successfully parallelled cells in modules when the modules themselves are in series. Also they are 24v modules while the cells are nominal 3.7v. I must be missing something I'm sure but I will be glad to get a clarification here

I use mine with a standalone fangpusun mppt 100/50 max 1400w.
There a 2 versions of this axpert inverter. Fortunately the ipowerplus version uses mppt instead of pwm. The mppt can deliver up to 25a from and the inverter can deliver up to 30a from utility for a combined 55a ie if you want to use the mppt on the inverter.

Good evening house,
Lost my 60 A MPPT controller of 5 years to heavy thunderstorms overnight and am trying to look for good brands Chinese brands that will also equalizer the battery effectively.
Can I get names of good high quality Chinese brands..

Sorry about this, you can try the powermr or makesky controllers. I have used the former for a friend's set-up and it works till date. You may also want to get an SPD to avoid future occurrence

I echo Ojeysky here. You need to look to your Lightning Protection System and grounding/earthing before you buy a new charge controller.

In my experience, the moment you mount solar panels on a roof, your risk of lightning and surge related damage goes up exponentially. Without a good LPS and earth/ground in place you will suffer catastrophic damage to both solar and general household equipment.

Based on experience which one is better?
New 100ah battery
Fairly used 200ah battery

Deluxe8000:

For goodness seek how will you compare the two?
There so many pros and cons.
I am not going to waste my time on sort.

I just want you to apply 50% DOD rule on both
Batteries and you will know which is better in terms
Juice they contain.

Thanks to you guys, this has tought me a lesson, will look into the lighting system when installing a new controller. Can you please advise the price range of this two and also I was looking at this before fangpusun blue solar 70 amps or flex max 60 amps don't know the difference between the two apart from screen

All Fangpusuns are clones (good quality clones) of another mainstream product.

The Fangpusun BlueSolar version is a Victron clone while the Fangpusun FlexMax is an Outback clone I believe.

The value proposition from Fangpusun is to give you essentially thesame hardware and solar charger performance as the main product but at a pocket friendly price - when it comes to software updates and features and support sha, you will be short vs the main product.

I love the Fangpusuns for budget installs, I prefer the BlueSolar clone for it's simplicity and budget friendly price - some people swear by the Fangpusun FM80 because it *appears* rugged due to looks and feel and weight - I do not agree all that makes a difference to the field performance - it does have a lot more bells and whistles that you can (mis)use and also subject to more measurement error and calibration drift.
