@ Kiekie
How much is this battery 12V, 200Ah AGM, in one other post I saw a guy claiming Kung Long is a partner to Schneider & APC but the award from Schneider was given to them in 2013, nothing else butress this claim.

Anyone in the house who has used this battery before or isbusing the battery currently? What's your experience with this battery.

@ Bodeface have you bought the battery? Please share your out of the box experience.

Hello Sir, pls its not a claim as the product is of good quality and I have sold/installed enough without issues till date ... Prices might go up soonest as I supply at 115k for now .. Awards isn't just limited to 2013 pls .. Feel free to contact me for efficient - fast supplies to any state ... Thanks

Then it might have been some transients from the generator. It's best you give it to a competent repairer, or try replacing the mos tubes yourself. That should solve it.

dejidotun2000:
The inverter was not being backfed. It was installed about 3 years ago and no modifications have been made to the wiring/connection since then.

@Kiekie, thanks for your elaborate explanation dousing my suspicions about Kung Long batteries.

My second findings is as regards inverters;
I have a Sukam 3.5KVA, 48V that has really served me for over 4 years and still serving, by I have observed that batteries (4x 200Ah, 12V AGM) doesn't last more than 2 years even with adequate care and avoiding deep discharge.
I have seen discuss here, though I didn't really follow it, about Sukam not having capability to effectively charge the battery.
If this view is uphold, what low cost inverter will you suggest, that has sufficient current and charging algorithm to effectively charge this 48V, 200Ah AGM monoblock battery effectively.
If my view about Sukam is not correct what will you recommend for me to do about this situation as the cost of battery has skyrocketed and I don't want to be replacing battery often.
Team, please help with your experience. Appreciate renowned brand proved and trusted to adequately protect battery and the parameters could be set to suit battery type.

i believe the sukam doesnt have a battery type selector switch...lumunious is also guilty of this. by not having a batt type selector switch, they end up using the same algorithm to charge diff battery types which the owner would connect to the inverter...
such inverters also dont obey the c/10 current charging rule..and this leads to premature sulphation n batt death.
you need to buy a new inverter that has all the above i listed. the mustpower and prag inverters hv all this and are affordale too. get a 48v of any of these models..and hope the damage isnt too far gone

Dear Sir,

How has your experience been with the Magnum PT100 Charge Controller?

I am sure vs. your old controller it is performing superlatively well!

In keeping with the house tradition, you should give us a review/tear down to educate us and broaden the knowledge base.

Thanks for asking. I installed the PT-100 but couldn't access the logged data to compare the performance. I bought ME-ARC50 monitor but unknowingly, it requires that i install Magnum inverter to use the monitor. The monitor does not work on standalone PT-100.

The maximum i have noticed on the real time production is about 2200w, similar to my old controller. However, i want to replace my cable with tiny flex these coming days. I will provide update then.

for clients that uses SUKAM or Mopower Inverter, I always insists they get solar system, most especially if they're using two banks (8 batteries) .
I have some using theirs over 4 years now and no issues. so you can add solar system and still enjoy the ruggedity that comes with Sukam

were you expecting PT-100 to double the output �

Good morning to you all and happy celebrations.

Please welcome me, I am a new member here.

Permit me to ask a few questions:

I have been using Chinese GEL batteries for sometime now; and I just got me two sets of FULLRIVER AGM 100AH batteries.

But I noticed something. The FULLRIVER batteries take more time to charge than the Chinese batteries even on the same solar array.

I am confused. Why is this?

Then when it finally got full, I noticed that the resting voltage is at 13.0V; while the Chinese one stays at 13.1 rest.

Is 13.0V a normal rest voltage for a fully charged AGM battery?

Finally, I used the AGM batteries on the same load as the Chinese ones and this battery refused to die.

Or perhaps, it hasn't calibrated well enough?

After three hours thirty minutes, it went to 12.5V and I stopped, it bounced back to 12.7V

The Chinese ones on the same load and time, would have gone to about 12.3V thereabouts.

Somebody, please come to my rescue because I am thinking the AGM battery is bad; especially as it takes more time to charge

and rests at 13.0V

Thank you.

so sorry you should have asked more questions before purchasing. Most of the brands make their accessories brand specific for use to enjoy the full benefit you need to get a magnum inverter. If I may suggest rather than throwing money at the problem why don't you get a second opinion of a Qualified installer to have an audit of your system there may be something your current installer is missing. There are a lot of good people on here that can help you. All the best.

JUO:

I believe so. With the erudite and knowlegeable comments he got on the various charge controller's available he probably was expecting double or triple output

You should be glad and rejoice Sir over your new batteries.

The issue is amp hour capacity . Your new batteries are still testing close to their rated 100ah capacity and since you are ostensibly using thesame charge rate as before, they take a longer time to get fully charged up.

This is a good thing especially if they now provide backup for longer hours than the old set as you seemed to indicate.

What you now have to ask yourself is what happened to your old set of chinese Gel batteries which have now lost capacity? How old are they now? Couple of months or over 1 year old? If they are less than a year old then you definitely need to change your battery management practices (ensure daily full charge, no more than 30 to 50% discharge per time) so that these new Fullriver batteries will not suffer thesame fate as the old chinese Gels you have.

PS: When fully charged and at rest without any charge source connected for some hours, it is normal for a lead acid battery to read anywhere between 12.8 and 13.2 volts per 12v battery. So you have nothing to worry about there.

In fact in my experience, the batteries that show up with very high voltage at rest e.g 13.2volts and higher tend to be the weakest

This simply show quality, as I always say Chinese brand always overrate...

I have been using Full River 200AH... Bought from kiekie1 fairly used... The battery performance is still the same as a new battery, my inverter has never beep low battery since April 2017..

I have only 220watts panel, Also I don't discharge more than 120watts at a time.. I use energy efficient appliances..

When my inverter complete full charge I noticed the controller will continue to put about 3 amp for some hours... It's never fully charged

I will take time this week to do capacity test.. charge to full, then use straight till my inverter beep low battery...

Does your Magnum PT-100 have a RJ45/LAN/Network port? If yes I may be able to help you with a PC to Charge Controller connection to view all the logged data.

Many factors combine to affect your daily solar yield - you mentioned that you have a 600ah bank - if you don't run air conditioning or other heavy loads off your batteries then I wager your batteries really don't get depleted daily - if that be the case then your solar output will be capped accordingly - if you drained your batteries more then you would get more solar juice subject to the controller's max limit.

The big question to ask is *are my batteries getting a full charge daily and entering into 'float' - if this be the case then you are really okay.

If not, we consider weather - with the harmattan haze and clouds nearly everyone will experience some reduction in solar yield during this season.

You did a ground mount system so you have easy access to check and correct slope of panels (should be 6 - 15° and not actually flat so at least water can run-off), are the panel surfaces clean and dust free? if not wash them, do you have any midday shade or overcast on the panels from the surrounding buildings and treeline? Shadows covering just 5% of one panel's surface area will reduce the yield of that panel and the connected string by more than 50%.

If you have a volt meter go open up the charge controller and verify the incoming PV voltage - you should be seeing over 90 volts (since you have 3 300w panels in series) by midday and if not one pair of your series connections is short (has just 2 panels in series). Whether your cables are thick stranded or thin flex should not really matter as long as you have a firm mechanical and electrical connection - this is especially true if you touch the cables when they are carrying peak amps charge and they are not warm or hot to touch - thinner flex cable will add nothing to the performance.

These are really some of the things you should consider before throwing further money or gadgets at this problem - if you don't want to trouble yourself then have another installer from the house do an independent system audit as you already gave your original installer at least two chances to give you good results.

You ticking off all the variables or getting a pair of fresh eyes and competent hands to audit the installation will go a long way to identify any trouble areas.

I suspect they dead because of lack of adequate charge since the setup is flawed from the beginning.

The setup comprises of sukam 7.5kva inverter of 120v DC, 10 200AH sukam batteries, three charge controller of 45a, 45a, 30a all three are pwm and 10 solar panels, the ratings I don't know since I am not the one that installed them but I suspect 150 to 200w.

Four of the batteries are reading 5. Volts, another four can't sustain charge, only two are 50% OK.

As at the time I went to audit the setup, the two morningstar 45a pwm charge controllers have a combine ampage of 4.5a 48v individually.

Good morning and thank you sir. Concerning your question, yes, the old Chinese GEL batteries were kind of abused, well not by me.
At about a specific time, I had visitors whom would still go ahead to turn on those power guzzling ceiling fans even when I have asked
them not to . . . And for the one week they stayed, I can say for certainty the inverter shutdown every single day; sometimes I wake up to see
11.1V. Something told me it would have a negative effect sooner or later. They are not up to a calendar year.

yeah the design was flawed from the beginning, thats the problem with a high dc voltage inverter. the 120v inverter...for it to effectively charge the batts, needs to hv 150v dc and above hitting it...n that 150v is also about the max input rating for the MS CC!....too bad you didnt vet what the installer did/get a reuputable installer...must be heart wrenching loosing those batteries ..@ this point, replacing them would gulp over 1m naira.

for your next setup..let the installer give you his planned design...and you bring it here for us to QA/QC it.
that 120v inverter is a serious hassle for solar panels n it isnt even a smart inverter too..only few CCs are capable of handling >150v dc and they are quite expensive.
such inverter is best for a phcn/gen setup
