thinkn of buying a Sukam 1.4 kva inverter and 2 100AH batteries. Can I use a locally coupled diesel generator to charge it coz d generator's output isn't stable ie it fluctuates?
How rugged are Sukam inverters? About how much can I get this configuration?
Thanks

Am currently using sukam 1.4kva inverter in my house. its a flat with 4room and master bedroom. If your generator is above 2kva it will charge your battery very well. The battery is 2pc of 12v 200ah and it will be fully charge with nepa in 5hrs and 6 or more depending on your generator watt output

Yes, i use stabilizer with it. I use century 5kva for the 3.5kva inverter in my office and 2kva stabilizer for 1.5kva inverter. This is to help regulate the power cos in my street there is irregular voltage.

This is not a nice thread. It is an execellent thread! smiley
In Nigeria now, Inverter is a necessity (if one can afford it). I've been using mine for 2 years now. The installer was smart enough to re-wire and place heavy points (A.C., cooking machine, pumping machine etc) in a different distribution point. Till I stumbled to this thread, i didnt realise that the batteries may not be charging well (3.5KVA Su-Kam inverter, 4 200aH Sukam batteries - all four now replaced within d 2 years). I observed that one battery die first (about 8v when down)not all at the same time. I've however started having issues with the inverter. Seems it needs some servicing. Not sure its something I can do myself. Please advice:
1. Sometimes when NEPA is off and battery is supposedly fully charged (51v max for the 4 batteries), if I power on the inverter it doesnt come on. But if NEPA or Gen is switched on it works. After NEPA outage again, if you try powering it, it comes up. What could be wrong?

2. Whenever I power the inverter these days (No NEPA), it trips off on its own and comes on again. Sometimes it trips off and on upto 4-5 times before it stabilizes. With NEPA or GEN supply this does not happen.

3. The LED display that shows you info on the status of inverter now displays only bars (blank). No info.

4. With 51v output on full charge, I reckon the batteries are not getting charged up right? Will it be wise to use an external charger? How can I connect it? SHould the batteries be disconnected from the inverter before using external charger? How much is the charger? Where can I get good one?

femiolorun: INVERTER DESIGNER IN THE HOUSE RIGHT NOW

having gone thru all the point stressed above, im here to give you reality about inverter starting from the battery

BATTERY
over the years i found out that the best battery to use for inverter is deep cycle battery
especially made in korea or malasia run away from china made but made in china with japan technology is also ok.

those point stresses above never state the kind of battery used, honestly deep cycle or as people call it inverter battery is the best
1-if your inverter has low voltage shut down then you should used your deep cycle for 2years
2-if your inverter has no shut down then your deep cycle should use 1.5year

The above point is on every day useage of inveter especially where there is no light (NEPA) and you depend on generator to charge but if you stay where there is NEPA then you are expect to use your battery more than the above calculation cos you battery will not be on the run most of the time
If you are using car battery im sorry wthin 3months your battery will be dead and dead for life

CHARGING YOUR BATTERY
THE PICTURE ATTACHED IS A SMALL CLAM METER THAT EVERY INVERTER USER SHOULD HAVE, SO THAT YOU KNOW WHAT IS GOING ON ON YOUR BATTERY DURING CHARGING IF POSSIBLE

Many people have use inverter and they are discourage due to charging, the truth about it is that when you are using inverter and it does not last like the first day that your battery is new you get discourage and let me tell you that if you buy battery and it serve you like 12hours, it should serve you the same hours with same load when you charge. But this rarely happen the problem is the charging.
So if you are using 100amp battery you need a minimum of 10amp charger and a minimum of 15amp charger if you are draining your battery to 7.5volt, the inverter battery has been built to accomadate such usage but you need a good charger to charger it back to 15volt(cycle use) this fact can also be seen on deep cycle battery. There you see
Standby use 13.2-13.8 and cycle use to 14.4 to 15.0 volt
Cycle use if for inverter application to which you discharge down to 7.5v to 8.2volt
Also if you are using 200amp battery you need a minimum of 20amp charging circuit to charger so that this and 25amp charger if you discharging to 7.5 to 8.2v
But I’m here to tell you that inverter with built in charger cannot do this charging this, but you will hardly know if you have regular NEPA in your house, but remember sometime that your so call nepa will be so low that charging become difficult and slow.
If you want to confirm this you can get this meter to read your current during, in fact I have seen a charger that is charging 200amp delivery only 5amp, the user of this was discourage and solution was given and was happy
So deep cycle battery with good charger will charger your battery to 15v for just 2.5hours and 1.5hours if its 100amp this is what you need to enjoy your inverter.

Inverter
If you want to run up to a duplex what you only need is 3kva inverter this will run virtually everything in your house with a single 200amp unbelievable if you doubt this I will seek permission to release number to you for those using it for you to have a check, when the whole house is on load together with small size frizer you run for 5hours but in the night when you want to run and load is regulated fan and some bulb on then you will use till day break and still use in the afternoon, this 3kva has be design to run both on single battery and two battery this inverter come with 30amp battery charger.

Local inverter
If you have local inverter that is not working fine, maybe humming or not running your fan, to the extent of burning it, we can give you a solution and you will enjoy it,

if anybody is given you inverter make sure it is deep cycle battery.
if you have already made inverter or local one and you are not enjoying it
for more info and solution pls call

Re: Inverter Users : Lets Have Your Experience by Vinsmuft: 2:32pm On Sep 26, 2012
I have been using my 1.4 Tec inverter with two batteries for almost two yrs with no issues. I just replaced my batteries last month and discovered that sometimes (especially when I allow the batteries to run down) my inverter does not charge the batteries. It will just show battery fully charged even when I know that the batteries are flat. Could the problem be from my inverter or from the new batteries that I just bought last month? Thanks to this forum, I now know that I should not let the batteries to run down totally.
What do i do? Please advise. Thanks smiley

Looks like you will need about 2kva inverter system. You can check our website to do your automatic inverter selection yourself. http://www.hisystems.com.ng/index.php?p=Power&s_p=Inverters#invertercalculator
Professional installation is critical for the durability of your inverter system. Avoid cut and join technicians! If you have any questions,please do let me know.
Re: Inverter Users : Lets Have Your Experience by Ethnan: 9:58am On Oct 04, 2012
kunletech:

Yes,you are correct to use 3KVA. But why really do you want to have your deep freezer too on the inverter? How long do you usually have power supply every other day? You can cut down your inverter installation cost if you do appropriate load selection. Check our website to automatically calculate the inverter size you require and the backup time you could get. http://www.hisystems.com.ng/index.php?p=Power&s_p=Inverters#invertercalculator

Bear in mind too that a professional inverter installation is key in ensuring durability of your inverter system.Avoid cut and join technicians.

Hello guys, I've made up my mind on buying a cyberpower 1.5kva inverter but a friend warned me that some inverters don't charge when the current is low or high. I have a friend who has luminous and he is thinking of giving it out now. Current in his area is low and doesn't charge the inverter and when he uses his generator, the current is too high.
Anyone with practical experience with Cyberpower with respect to charging?

Just tell me what you want and we will give you an inverter system that will last for you.The key stuff about inverters apart from buying a good one,is the installation.You can have a good inverter and if its not installed professionally,you will keep having issues. You can visit our site on http://www.hisystems.com.ng. Cheers
Re: Inverter Users : Lets Have Your Experience by voltront: 4:04am On Nov 08, 2012
I have read every single post in this thread and i most say i appreciate you all for sharing. I have a 1.5kva (6months old new batteries) luminous inverted that lasted over 9hrs on the first use. Since then it goes just 3-5 hrs. It shows "battery charged 99%" after just 2hrs of charging. I would like to know if that's how luminous inverters work. Anyone who is conversant with it's operation should please comment. Thanks

It looks like your batteries are having issues. You didn't say which make are the batteries. Since the inverter is charging the batteries at all,it looks the battery doesn't retain much charge. Was there anytime the batteries were left in a discharged state for about one week? leaving a battery in a discharged state for a long time could permanently damage the battery and drastically reduce its capacity. visit us at: www.hisystems.com.ng
