Hello solar gurus in the house. I've been a silent follower of this thread. I recently have a concern about the poor performance of kung long batteries in an installation in less than 6 months, I want to know if anyone has a similar experience with the brand.

The installation has 4 pcs of battery connected in a 48v setup.

The inverter used is ipower plus 5kva MKS axpert inverter.

The system has 3000w of solar installed (200w ×15) connected in 3×5 set up.

Average load on the system is 650w

Battery backup for night time use was up to 6hrs initially, but now barely last up to two hours.

I've tested the batteries, they seem OK, (just low on charge).

But after charging for approximately 15hours, same issues noticed.

Has anyone had similar experience with this brand or any brand??

What can be done to salvage the situation??

PS: there is no stabilizer used in the set up, cos power supply is fairly stable.

Any/all contributions and suggestions will be highly appreciated

well, inverter inefficiency and/or battery ineffectiveness has been pointed out.

however, my small little personal observation is just the design. 3000W PV array on just 200Ah Battery Bank
that's about 62A (3000W/48V) hitting the battery during bulk charging. unless you're running freezers and ACs during the day.... which is even unlikely since it's just one bank.

@ the Bolded, Something was Wrong from the Start.
From what you stated, Seems you always discharge to 90%DOD

650 Watts for 6 hours is 3900WHR, Your Bank is 9600WHR.... Equation no balance.

Your Load calculation is wrong, Do another Energy Audit first.

You have enough Solar Power, Upgrade to 8 Batteries use Quanta or equivalent.

Are you totally off Grid? In that case you need to upgrade panels up to 4500watts and Minimum 8 batters

Thanks for the observation, but the charging amps was adjusted to 40A for either solar or utility charging (not totally off grid).

Thanks for your suggestion, I'll carry out another audit and hopefully post the result here.

But the battery couldn't have been discharged at 90%DOD, since inverter has a low battery cutoff of 44.4v

My understanding is that manufacturers are forced to specify the maximum amperage that their equipment could draw within the rated working voltage range.

For a TV labelled 100-220v & 2.9A, the maximum power draw is 290watts (100v × 2.9A). At 220v, this same TV would draw 1.3amps.

So 290watts is not crazy but certainly high for a modern day TV - a normal household freezer may not consume up to 290watts sometimes.

What you should do is plug this TV into a watt meter and measure the power draw at various settings - JUO and other forumites carry a plug in watt meter.

fogechi:
Please what is the wattage of this my TV:

100-220v 2.9A thats what is written at the back of the TV

Yaaaaay QUANTA!

Of all the batteries I have used, they are yet to dissappoint me - even when stubborn clients abuse them (2 days at a proper charge reset the battery back to life).

Not saying they are invincible but certainly well designed and durable.

earthrealm:
@braaad.
Chk the charging voltage setpoints on ur inverter and cc...and confirm it corresponds to kung long.
I hv 8 pieces of kung long .not so impressed with its performance..but still working ok.
When fully charged at night i tested a 1.5hp ac for 60mins and the voltage didnt go below 50.8v

I wud suggest you install the led voltage display to each battery and observe .then load the system with a 1kw or 1.5kw load and observe the individual batt voltages again...
I suspect you may have 1 or 2 bad batts in the bank...also xchk for a loose batt connection

If i cud turn back time...i would hv gone for the quanta batts

Boss, at 44.4v you would have indeed flogged the battery to 90% or even worse just as OP said. At 42v (10.5v per 12v battery) your battery bank has zero charge in it and is 100% spent for all practical purposes.

I do hope you set your low battery cutoff to something above 48v e.g 48.4v or 48.8v - this range is approximately the 50% cutoff and any further discharge will likely give you shorter battery life.

You should examine your charge algorithm viz absorb voltage setpoint e.t.c, appliance load at various usage scenarios (can be read off the Inverter screen) so you can find out where things went wrong.

For Solar Charging, that incomplete absorb (going to float too early) is a very valid issue as I personally experienced it with my then Zinox 5kva - like Oga Barezzi, I simply repurposed the inverter for another use - I had not learnt that there was a firmware fix at that time since I was not coming to this noble forum for self-development way back then.

Random thought: - Could you tell us what your absorb voltage is set to?

The AGS relay on the Mustpower is typically energized to send a start signal to Generator when you reach the low battery cutoff - 10.5v or 11v depending on how you set your inverter - this alone is pretty bad as the batteries are already too far drained before the AGS will start a Gen - unless you happen to have a brand of MustPower that allows finer LVD customization?

To make your Gen start, you connect wires from AGS to the appropriate receptacle on your Generator control panel - playing around with a diesel Gen's control panel, you want to be sure you know what you are doing or seek professional help as a mistake could be costly.

pitodenz:
I have inverter that's with AGS slot automatic generator starter, pls anyone have idea how to install this on a disiel engine like mekano or perkins, do I need to build a panel for this or the inverter already have the panel inbuilt?
Note* the inverter is Mustpower

Thank you Sir

I think you are on the right path - you could borrow a DSTV power supply - they output about 12.4v or so and I happen to have one or two lieing around as well if you are able to pickup.

No you don't need a resistor.

Interestingly, I was forced to start external switching between Mains and Inverter this weekend as my Red VilPower 6kw had progressively stopped passing the line over time, then stopped charging altogether on Thursday so by weekend I layed hands on a LC1D25008 contactor and removed the mains from the Inverter and routed it through the contactor and so far working beautifully - this will be the arrangement till I can save up for a premium inverter (been itching for a Victron for a while)

See if you can spot which wire is which from the pictures (I switched only live wires for simplicity and I used 4MM wires for all the Common and Load (I run two ACs and other stuff nearly 24/7) except for the signal wires which are 1.5MM

Trippledots:


Caveat noted loud and clear sir....i am comfortable to a reasonable extent working with Electrical wiring and safety.

First of all thanks for the response, and i like the way you reply. There is something just nice about it.

So to the points raised:

1)I did see the type of relay i went in search of, but that was only after i had picked the current one I'm using. I reasoned that that contactor rating was an overkill... All the loads I'm transferring are virtually non inductive; Led TV, led/ cfl bulbs, and a couple rechargeable fans. My ac, freezer, and a dedicated socket for maybe blenders and other motor loads will be permanently on grid supply.

2)Confirmed... No heavy inductive load.

3)Nice observation boss. I'll look for a 12v power brick to replace it. By the way, since its purely an inductor do i need to connect a small resistor in series with it? What do you think sir?

44.4V... that will kill any battery... You load is obviously more than 650watt.. We were changing Batteries every 6 months due to same reason... You need to properly size your bank and Inverter will take care of Efficient charging

Your battery bank is too low.. Charging current is too high for 200AH, Ideal charge should be around 20-25Amps....

Namzy:

Someone on powerforum sa compared axpert scc with that of victron and results were similar in fact axpert may have won that battle. Some in that same forum have been using theirs for years. Well mileage may differ i am enjoying mine for some months now and my parents have been using theirs going to 3 yrs now

We v more of complaints than testimony. It's beta to use wht works for all nd not wht works for few.

check my profile

Quanta charge specs are rather confusing.

The manual mentions a "freshening charge" of 13.8v before installation.

Personally, I use max absorb voltage 14.2v per 12v battery *Temperature Compensated*

If no Temperature compensation then I do a max 14.1v per 12v battery.

@pickup.. That will be nice. Where do you stay?

@contactor... Aww, thank goodness you have a good grasp of electronics. You would have spent some fine money trying to fix that inverter. right?
But, since your inverter isnt charging anymore do you now use an external charger for your batteries?

@victron.... Yes ohh, that thing is badass. We use their line of products where i work.

@spot... I am not adept at contactor usage, but if i understood you well ; a pair of switched live wires, one common wire, one load wire, a pair of signal wires. Thats 6 wires. And i can see 6 wires. Lol. QED (i see the smaller signal wires) nice.

ElektroPhaim Solar!

Location is Lekki - you can pickup directly or arrange a bike courier - just let me know in advance so I can have it ready.

No plans to fix the inverter for now - I don't really use the charger function as I was setup to be 95% offgrid but middle last year, I setup a timer and contactor arrangement so that I would always use mains electricity if available between 8pm and 3am daily - I needed a contactor to route the loads through because I also had an AVS between mains and houseloads and the AVS would not pass the average 2kw and peak/burst 4kw of loads I had in the evenings and ditto for the timer too - they would just melt under the load.

I basically used the timer switch to feed power to the AVS (between 8pm and 3am daily) and then the AVS to energize the contactor coil only if the line voltage was between 210v to 235v. Both timer and AVS carried zero load, they just passed along the voltage signal for the contactor coil.

So I was basically using the inverter at the lowest charge setting since the primary goal was to bypass battery and power house loads directly from mains - but once the inverter charging function spoilt by itself, I happily got a second contactor to simulate the inverter's internal transfer case with the bonus that my setup was now more efficient with the charging disabled. So with 3k for the contactor and 15minutes spent rewiring I was setup and good to go.

Oga Pranil once said I needed to graduate to using ESS - well he was right! - Victron is the next brand I want to try once I am able to afford it - I have gotten tired of all the random issues with the Mustpower type inverters - the only ones I would touch now are those with an organised service center and good customer service such as Felicity.

Evening guys,
Abeg is it really necessary to add a circuit breaker between a charge controller and the battery?
Charge controllers are designed to throttle the current at it's maximum rating. What's really
the function of that CB?

You remind me of the contraptions i've rigged up at home. I tried to duplicate the dual Ac source and dual ac output of a typical Victron Quattro...
3k contactor? I must have been scammed. I use an 80A 2NC 2NO contactor, and it cost a bit more than 3k sha.

Lol My Oga. The sages say necessity is the mother of invention

You got a much larger contactor than I use - 80A 2NO 2NC to my own 40A so it makes sense that you paid more.

What I find though is you get better prices as you move closer to the source so my first ever set of LC1D25008, I got at 20k for two units including delivery to Lekki, same contactor I got now for 3k each as I cut out the middle man and moved closer to the mainland source - if you factor logistics they came at 4k each now.

Interestingly, I just took delivery of a batch of stuff from Ali... 25A Tomzn 2NO 2NC contactors and each cost under $6 - after my trials, they will now be my electrical switch of choice for large single load or multiple small load switching applications for my clients, the prices were so good I got a few random stuff as well - several large capacity AVS and diverse DC breakers - with a few hacks taught to me behind the scenes by a member of this forum, I got the entire package to land at my doorstep in a little over 1 week at a great price.

Your comment about duplicating dual AC source and output just sparked off a few ideas in my head, I will experiment and revert if I succeed - I may yet make my own Victron clone afterall.

Hahahahaa.... I like that clone idea thingy oh. Isn't that what the chinese do?.... DIY can be fun abeg.

@bolded... I'm reeeeally interested oh. I had to wait a month plus for charge controller and inverter ordered from ali. The wait was exhausting.
Can we talk whatsapp if thats ok. My bio has a link to my Whatsapp. Expectant.

@price.... I got that small 10A relays I'm using for #400 a piece. I just bought two incase one fails. It was dead cheap. I'm already playing with an idea in my head for the other relay. Whereby my manual start generator excites a second relay that transfers the load to the gen from grid. when the gen is put off it returns to mains. That way i dont have to always use a knife switch to switch between grid and generator manually. The gen will be turninoniown. �

You did pretty good! Especially considering all you had to go with was an unlabelled picture with all wires floating free and not terminated yet. I happily award 9/10.

My tech background was originally in computers & network systems but electricity had always fascinated me and slowly began to dominate my every thought - with a lot of training, practical experience and invaluable insights from the members of this forum we keep learning and getting better daily.

Interesting idea. The possibilities are truly endless if you put your mind to it.

For the mentioned application though, I would be happier if you used a suitably rated contactor instead of a relay, granted your loads are small but I just prefer a sturdy device for switching and you would also need to isolate the loads the contactor will switch e.g you don't want your small Gen to try to power up the AC or Microwave or Freezer or other high wattage appliance when the mains supply fails.

See below a picture of contactor vs relay - see how small the relay contacts and internals are - hard to get thick wires into the relay and their mechanism of failure is also more a bit more spectacular.

Safety is very important above all else and we don't pray for any mishaps - for this reason, I have a bagful of relays I will no longer use since my needs are medium to heavy duty - free giveaway as well for anyone who can pickup who wants to use them for very light duty applications.

Now I am looking for that 80A relay Oga Dapsyra mentioned to play around with Source anyone
