Hello sir...I need those kinds of battery.
are they new of fairly used? where can I get them?

Im in the south.

xreakz:


How much current do you get?

Here is my battery type. I think it is gel

shithapuns:


ur batt appears like 2v 500ah batts?...abi 800ah.
pls confirm the amperage, 500ah wud be easier for ur cc to charge than 800ah, hope u know abt the c/10, c/8, c/12 formular for smf/flooded/gel batts

They are 2v 500AH. I dont know abt the c/10, c/8, c/12 formula.. But am right.. Are these gel batteries

Sorry sir.. Got them a while back. The guy no longer stocks them

Good afternoon house.Please can anyone in thouse help see which of the diagrams below is correct for 12v 2*200ah parallel connection.Because i saw a video online saying i should use fig.2.

figure 1 & 2 are the same but figure 2 is more efficient. Figure 2 will make sure you have equal voltage at each battery during charge and discharge so use figure 2

Opt in for FIG 2 ... Tnx

Fig 1 is neater, just use good sized cables and short ones to eliminate voltage drop.

@xreakz, those batts r gel, u gotta pamper them real goods, gels are quite reliable, but delicate, once they dry out, usually caused by overcharging/improper inverter/charger...then its all over, its irreversible....priced dem a cxouple of months ago, they were going for btw 38k n 45k for new, toks abt 25k or 30k

hope ur inverter/cc/batt charger has a gel setting?

The man!!!...reliable and efficient..makes no noise.
Bought an item from him.
Good customer service...even his staff i spoke with was well spoken n courteous.





@kreatz...1.5kva safe power wudnt charge those batts well...ur case is more of undercharging than over charging...neither which is good.
To fully recharge ur system if u ever drain them might take upto 36hrs non stop charging...cos i know the max current from ur inverter wudnt exceed 15amps.
Remember the c/12 rule for gel batts. C being ah of batt bank wch in ur case is 500ah...thus u need an inverter that can output upto 40amps for the batts to b happy. N hv shorter recharge time

Hi all,
please help with these questions
I have a prag 24V inverter with 4 batteries, NO solar panel and charge controller yet but will come later, how do i know if my battery is charged since prag charge indicator will only work for a while and the indication will stop as if the charging is complete. so some questions
1. Can I test the batteries with multimeter while on power, actually has been doing this
2. What is the average DC volts in multi meter to know if the battery are charge when there is still a source of power (eg Generator or NEPA) and when there is no power.
3. What is the average lowest DC volts measured from multimeter when the battery is discharged
4. I noticed that most of the time, only battery 1 and 4 are seriously discharged while battery 2 and 3 remains almost the same while prag is showing that it is remaining 2 bars. Any explanation for this.

i checked online for examples of how to connect the batteries and it seems all is fine concerning battery connection.

Attached is a charging curve which also applies to prag a floating battery with charger connected is usually 15.5 x2 =27 V.
Battery on boost charge near end of charge will be 14.5x 2 =29V
= battery under load will show terminal voltage below 12.5 V x2= 25 V
Heavier the load lower the volage .so it is not good idea to check voltages on load unless you have a chart from manufacturere
The lowest voltage normally is 10.5x2 = 21V when fully discharged ( lower for a bad battery )

If the equalization programme is running the volths can be near 15 v x 2 -=30 V

I think On your prag the dip switch 8 is for equalization ( marked red) I suggest if the batteries are showing different terminal voltages run the equalization first ( disconnect on other things from battery if any except the prag) mand esnure atleast 4-6 hours of uninetruppted supply to the charger /inverter


The only way to know if a battery is good or bad is by capacity test ( how many Ah can it give) or internal resistance with specialized tester or specific gravity in case of flooded .

From my experience terminal voltage can give you false indications specifically as terminal voltage is also dependent of battery and outside temperature by a large extent

As a general rule batteries have a life based on DOD ( depth of discharge) Higher the Depth of discharge lower the life of thee batteries . if you have owned eh batteries from day one you can probably estimate the life

best luck

is it this stabilizer you are referring to? Please note this stabilizer has no battery selection but if you use a normal deep cycle battery, you are OK with the 20a charger. The maximum charge voltage is 29.3v. You can upload photos of your connection

@codeme, ur 4 battts shud discharge at same rate, its either they are not connected properly ...or the cables might be faulty/poor

@pranil, thanks for the chart, a quick question, i hv a 48v inverter with 4 units 12 v batts in series,...
when partially discharged, my batt reads 49.2v, with small load {2units of 70w ceiling fan} when i connect a small freezer to it {130w] the voltage drops immediately to 48.4v, is this normal...or are my batts weak

Voltage drop is normal. Are you measuring at battery or inverter terminals. ? if the battery interconnections are small size it will drop more Does it come back to 49.2 or 49.1 when small freezer is removed ?. You are safe even if it temporarily drops to 11 V under even load as long as it comes back up. 130 Watt is a small load. I load my 48 V ( 200 AH x 8 ) battries upto 5kw sometimes and they have no issues the voltage will definitely drop but recovers back to normal when the load reduces

Actually you are the blood is in you please try and be.
I eventually discovered that 2 of the 4 battery are dead on arrival. They discharge likeno man's business,
What is the best practice should I remove them or leave them. What are the disadvantages or disadvantages of leaving them thanks

what kind of batteries are they?...if flooded you hv a higher chance of resuurecting them, if gel....its all over.
your best bet is to change them if all fails, they will slowly kill the 2 good batteries over time.....

Hi All, many thanks for all the wonderful information being shared on here.

I am curious though about people buy separate inverter and mppt charge controller when there are Hydrib inverters that does the same job now with probably less or the same amount of both combined, is there any specific reasons for this?

I am curious though about people buy separate inverter and mppt charge controller when there are Hydrib inverters that does the same job now with probably less or the same amount of both combined, is there any specific reasons for this?

example below:

The separate charge controller and inverter might allow you to have higher rating on either charge controller or inverter than possible in hybrid say 60 amp charge controller but 8 kw inverter . Also they are likely to be more durable individually due to long history of development and heat dissipation

personally I prefer the Hybrid as they are invariably smarter with PC monitoring , generator start control , software settings etc. .Also Most of them can be stacked or paralleled so you can increase your rating both on load side and connect different solar strings ( makes , watts) to the same battery


Personally I am using two hybrid inverters powering two circuits one inverter runs 1000 watt powering only electronics and sensitive application ( runs like giant UPS) and takes the battery and solar inputs but never charges battery or is NOT connected to generator input. The other inverter runs on 1200 Watt solar but runs my waterpump .and two AC's plus non sensitive loads like compound lighting . This inverter is in appliance mode shifting to grid or generator whenever available and simultaneously charging batteries.
Both are connected to the same battery bank . so One inverter is essentially supplying the DC power through the battery bank whenever the grid or generator is running

without smart hybrid inverter such setup is impossible . Thsi allowed me to get rid of all the small UPS in the house essentially saving 200-300 watt load

@dejavus, am interested in that hybrid inverter u posted...whats the price and specs?
ipowerplus seems to b the cheapest hybrid inverter avasilable in nigeria, the other makes are much more expensive...defeating the the cost saving of going hybrid..

also zinox the marketers of ipowerplus appear unserious, cos even on thier website, the option to buy the product isnt there.

3rdly @ house...am looking for an offgrid inverter (without charging capability - this is to save cost),,,,1.5kva or 2kva 24v or 36v... who can hook me up with such?
