I was speaking in general too. Gel batteries can usually be charged faster than Flooded - what Gels are extra sensitive to is the charge voltage because an over voltage condition can rapidly cause gassing and bubbles to form in the gelled electrolyte.

I should probably know too having used Flooded and now Gel batteries as my sole back up power source for 3 years +.

A 5% charge rate sounds like a very specific type of Gel battery and not the general case.

In support of my position and for general info, I tender two sources, one a prominent battery manufacturer and the other a prominent battery charger manufacturer who both should know their batteries.

bigrovar:


Not really o. Gel are generally the worst when it comes to charge and discharge rate. While most flooded can be charged at 10 to 13% of their capacity at c20.. Gel are advised to stay around 5% in fact gel are suppose to be slow charged and if over charged can be easily damaged with bubbles developing. Over charging does little to flooded battery at least in the short term. Most of the extra amps can be converted to heat which can resort to electrolyte boiling and water lose (which can easily be replaced) for gel over charge can straight away cause irreparable damage.

harizonal123:


3 weeks old. For now charging very well but the bulk charge value is set at 14.2v and its not adjustable. Which I think it's a little high. Will change it as soon as I have money to do so

it is adjusted. Just press hold the mode at that voltage and use the +and- sign change the voltage if you wish change. But lead battery should be charged at that voltage except for equalisation charging.

welcome to my world.
give details of your batt and config,
what is the charge setpoints on your cc??
what is your primary charging source, give the ratio if possible, grid/solar

4# Luminous batteries 48v set up
3.5kva Luminous inverter
Fangpusun CC, Absorb setpoint=56v , Float set point= 55.4v
Primary source of charge is PHCN and solar panels(300watt, 12 numbers, 3s4p)
Of late phcn has improved and am getting close to 15hrs per day.
I observed that my Luminous inverter has 3 charge current mode(high, medium,low) and currently selected on high mode, don't know if to change the mode.

first offs, that luminous is a dumb inverter and not so suitable for present day batteries. hence i wanted to know your primary charging source, it doesnt have a battery type selector switch, hence uses 1 algorithm for all battery types, it may be sending wrong/high voltage to your battery

2. crosscheck that your fangpusun setting corresponds to the knob setting, what i mean is, on the victrone clone fangpusun models, the battery type selector knob doesnt correspond to the batt type software inside the CC, the knob is 1 step ahead, for eg, you set the knob on 3, if you access the menu to crosscheck, you will see that it is on setting 4 [which is for another battery type entirely], so you need to put it on setting 3 to correspond to 2..... hope i didnt confuse you further??

in a nutshell, what am saying is --- access the cc software and confirm that the batt type and voltage you selected matches

3. being that phcn is now your primary source of charging, its likely the damage is coming from your inverter, if you can turn off the utility charging and let the cc charge the batt for a day and 2...and observe for any changes.

4. those batts with higher voltages may be half dead already and their voltages is way higher than recommended.

5. try swapping the led voltage displays to different batt, and see if any changes happens --- wondering if the displays need calibration

NiyiOmoIyunade:
So sorry for the damage.

The relay is supposed to be rated around 25-30A. Were you switching loads larger than the rating? Perhaps with grid available you were running the inverter at or above its rated capacity? This is a common failure mode when grid supply goes off while heavy loads are being powered and the relay attempts to switch a load larger than it was designed for - especially inductive loads

Mr Niyi, yourself and Mr Pranil should apply for discos license!!

Seconded, especially Mr pranil whom I don't hear from much now a days

harizonal123:

.
NOTHING LIKE THAT exists.

Long batts for instance absorb voltage is 14.6v to 15v
genus battery is 14.4 to 14.8v
luminous batt is 14.1 to 14.4v, i think..check, its written on the body of the battery
etc, as you can see, all these batteries hv different absorb voltage setting, thus thats why an inverter with selectable batt type switch is recommended.

@outback clone, raised the issue, so you can check, if same problem exists in outback clone

move the led display from the batt reading 15v to that of 14.2v and vice versa

I belief u meant 750va/12v? Y not get 1500va/1.5kva, 12v for the freezer alone. This will give u rest of mind.

Thanks @ Oshomo12. And sorry, my bad. 750va I meant.

So you assume the 1.5kva inverter will handle a surge current of 1,500 watts of the freezer comfortably?

By the way, does anyone have experience with the 12v/1.5kva version of this product here as regards the surge power it's capable of handling?

olatade:
i have a question. i use a luminous hybrid inverter and I'm planning on upgrading to a felicity mppt charge controller. the question is,will charging the batteries with the inverter and controller simultaneously have any negative effect on my batteries?

I don't suppose so.

It will just be like when you have both a standalone 220v battery charger and your SCC hooked into the battery. Both will charge as they should, carefully guarded by their respective charging algorithms vis-a-vis the SOC of the battery, which will of course be entirely different from when each is used separately.

Trippledots:

This your charger, is it serving you? How long have u been using it?

I use a 20amps version of that charger. Been doing well for about a year now.

Any medium range inverter of 1.5kva should be ~ 1050w, say a PF of 0,7. D inverter should be capable of *2 surge(minimum, so that will be 2100w). So, yes it can handle a 1500w surge. Some inverter claims *3 surge.

Lucky you. 20 amps is a little small for my intended use. The 30 amps i got kept failing repeatedly, i simply lost faith in the brand name and dumped it.

On a second thought, maybe two 20amps in parallel may just do the trick

Looks like its self correcting itself

hi all,

i have two wattmetres that stopped working, opened them up and found batteries inside. apparenty those batteries are gone. the thing now is that i discovered those batteries were spot welded!! what can i do to replace the batteries?

mikylon:

i think you shud still investigate the issue, if you are using luminous batts, and the max absorption voltage is 14.4v and your system sends 15v to it regularly, such high voltage for an extended time, will kill the battery, my take is your batts may not be at equilibruim/SOC, or you mixed diff batts

Been following this thread keenly for sometime. Does anyone know how to get data out of a Fangpusun solarblue clone150/60 CC for analysis on maybe Grafana on a raspberry pi? Would appreciate if you could point me in the the right direction. Thanks

Those are rechargeable lithium button cells. 3 days ago, I burnt the 12vdc/12vac input/230VAC output sinometer I had by plugging it into a 220VAC socket. Two pieces had been lying fallow unused for about a year and both batteries were presumably discharged. I was able to rejuvenate the 220VAC input within seconds of plugging it into an AC socket while the 12VDC/12VAC input plugged into a 12vdc source only lighted the manual led but the LED screen wouldn't come on after about 30 minutes. I got impatient and decided to plug it into an AC socket and poof!

Now in hindsight, I should have simply removed the spot weld (it's possible to just do it like you would the 18650s) and use the 230VAC variant to charge it, a long process that I was unwilling to go thru and thinking I could get away with a quick 220vac on 12vdc/12vac. What da heck was I thinking?!

I will advice you just get a sharp long nose plier to pry the nickel contact off the battery, it's a 1.2volt nominal button cell which is totally discharged so I think you shouldn't worry about any fire hazard associated with the lithium chemistry shytes. Get a rechargeable replacement and just solder it (in the absence of a spot welder).

@impatient... Lol i knw that feeling. Very sorry for the loss of equipment.

@battery... I never knew lithium had button cells oh. Thanks for the tip on removing them. Where can i get a replacement for it? Or would a normal button cell of diff chemistry work? Maybe its supposed to charge the lithium cells hence I'm asking abt the diff chemistry swap

I use luminous 900vac inverter with 100ah battery. I recently bought a 200ah mercury battery. To my surprise unless I switch off all lights, TV etc the battery will not charge. Why is this?

Also, the inverter fan is no longer working. Why?
My panels(3×150watts parrallel connection) are fluctuating between 0.1 and 4.5 as reported by the controller. I understand that's due to cable length and size but I can't afford 6mm or 10mm cable now. If I place the new 200ah battery on it (solar) , will it have any adverse effect? I am using it to charge the old 100ah battery but it lasts only about 1 hour now. Please advise. Thanks
