Pls where can I get a 5kva hybrid MUST inverter.
I heard they are a different brand from Must power inverter.
Thank you

Namzy:

Looks like voltronic axpert 5kva aka ipowerplus 5kva. I know must inverters have an axpert clone with mppt and another with pwm cc

smf/agm wahala, reason why i love fla.
so the bank ran down today, as low as 45v or so.
the 4 batts on the left are about 6-7months old, while the batts on the right are 3 to 4months old. each bank has 1 balancer+1 desulphator.

my theory is that batt 2 failed on left bank, and has inadvertently damaged batt 5 on right bank.
am proposing replacing both batts to try and salvage the situation, 2ndlly i intend deploying a copper bus bar.
all batts tested ok to a 100amp load tester few wks ago when fully charged.

am open to suggestions on how to prudently salvage this situation.
abeg ignore the crude display box

Without killing your hope, the batteries at 8.35v and 10.5v are substantially dead already - especially as you have a balancer attached and they still deviated that much from others in the bank. Less than 8 months is rather short for brand new batteries to fail so badly - you should look into your battery management practices to find where you went wrong - if you did everything by the book, I would blame the battery brand or the fact that you mixed older and newer batteries together and perhaps different brands too.

If I were you, I would quarantine the weaker batteries for now and use only the best four (those still above 12v) pending the outcome of my battery salvage efforts.

Namzy:

Thought you will be maintaining 50% DOD max. I bought a fangpusun bmv 700 and aim to set the cut off at 50%. Hope u revive them shaa. Any equalization history?

earthrealm:


ooh, seems i have a different opinion,, i believe the battery reading 12.2v is bad, why is it not contributing to the bank?...maybe because its not contributing much, made the batt opposite it to give its all in other to compensate and that caused it to fail too -8.35v is gameover for most batts.... some batts fail like that wil show ok voltage, but unable to carry load

the batt of 8.35v is certainly bad as well , the reason why 3 batts are in the 10v~ range and the other bank is 11v~ range maybe be cause of age difference or ack of a busbar, will instal a busbar to reduce the variables. the batts are same make . kung long. firs bank [left] are about 3 or 4months older, and for the first 2months or so..didnt have a balancer or desulphator attached

@namzy
the inverter has a battery cutoff setting at 10.5v and 10v per batt, i set it on 10.5v. we have fairly stable phcn, 8 to 12hrs daily, except for some bad days like this, when phcn messes up, and my panels are inadequate to keep up. am also increasing the panels to forestall such from reoccuring

so you say my plan of replacing only those 2 is flawed??

NiyiOmoIyunade:
Interesting ideas about which battery in the bank is good or bad - you could be right but I can't agree because you have balancers attached and electricity always follows the path of least resistance - except your cabling is faulty or poorly crimped, I see no reason why one battery would be stingy and hold on to it's stored up charge allowing others to suffer - each battery will give up all it is asked whenever the load calls for it subject to the battery's capacity - If the battery is prematurely spent vs. the others, that is when the other batteries would take up the burden and begin to suffer - therefore the battery with lowest voltage under load is typically the weak/bad one

Neways, the only way to know for sure is to charge all batteries back to full individually and then run them down with a known wattage load individually as well. You will have an idea the Judases based on how they individually respond to charge and discharge - this test can only be done individually please (charge and discharge individually) no shortcuts!

So you had KungLong batteries? I am even more worried now as I have clients who are significantly exposed. Chai

Can you give an idea of your battery config - nominal voltage, number of series and/or parallel connections, absorb and float voltage e.t.c

earthrealm:
@niyiomo, would provide other details later, i have had 2 automobile batts that failed in similar way. it would display normal voltages above 12v, but on attempting to crank the car, the voltage will suddenly drop to below 9v, i have also had some inverter&generator batts that failed similar way....thats why its advised not to rely on voltage as the only test of a batts health.

you may google the condition, its quite common!

DUNKA:
Seems Kung Long is not as durable as been advertised. Seems to have a high rate of bank failure within 1 year of installation.

earthrealm:


Yeah...beginning to think they r over rated.
Am thinking of replacing the 2 suspected bad batts with quanta batts...
I know its advisable to use similar batts..but as it is now..am contemplating taking the risk.
What do u guys think??

DUNKA:
Why don't you just bite the bullet now and change out your battery bank altogether? I know it is expensive but it will be cheaper in the long run

Ngbam!

Oga Earthrealm sadly has more than two bad batteries although he doesn't want to believe it yet - any attempt to change batteries in bits is only going to worsen the situation.

Especially, Quanta cannot easily mix with KungLong - although both AGMs, their charge profiles (ideal absorb voltage) are very different - Quanta tops out at about 14.2v for absorb while Kunglong starts absorb from 14.4v. More especially, brand new batteries in pristine condition cannot mix with 8 month old batteries whose capacity has already been impaired.

It is either you start afresh or attempt to salvage 4 decent batteries from the entire bank of 8 while raising funds for eventual total replacement.

earthrealm:


LOGICALLY, THATS THE proper thing to do
economically, na financial suicide you dey talk so.

na for business place, and 8new batts is 1m naira+ what i have spend already , na 2 pack go village remain so for me.

@niyi, since long and quanta have different charging profiles, what other batt has similar profile with long?...luminous?

am a gambling man, so i prefer risking a lil over 200k on replacing 2 suspected bad batts, than splashing down 1m on 8 new batts..

a lil discovery i made during all this.

1; this lcd display for batteries are very very essential, i recently installed them 3 months ago when i added the 2nd bank, perhaps if i had them from the get go..i wud hv spotted the suspect failing batt from the get go. i advice any inverter owner to make it a must have for their setup

2: pulled out my idle 8.5kva gen and attenpted to charge the inverter, the 5kva highpower inverter charged smoothly outputing 35amps at max setting no hiccups, same gen finds it difficult to charge my 4kw muspower at max charge rate of 31amps, the charging current isnt stable, as a result of the slight unstable ac output from the gen. the highpower inverter handled the unstable gen ac output like a champ...was outputting steady 35amps, no flunctuations.

Hello fellow DIYers....yesterday we lined up an alternate power line from my inverter to our sumo water pump I was told to be 1hp. At start up my 1.5kva inverter overload light came up and it shut down on the overload protection mode.
I know some guys here pump water effortlessly with their inverters so my question is which brand do you guys use.
Currently I use a 1.5kva Eco luminous inverter.
I'm skewed towards a prag or same luminous but with 24v battery bank source. But open to FTA advice.....not adverts
