This is the thread i need right now |
Re: Inverter Users : Lets Have Your Experience by toluxa1(m): 5:43pm On Jun 08, 2011 |
Hello House. Interesting topic indeed. I am a final year student and I just got a little self contained place. I have a small inverter - not sure of the KVA stuff until I check (the size of a big stabilizer). I intend basically to use to for 1 bulb (energy savin), laptop and tv. Will that be possible? Can I use it with a brand new car battery? How cheap can i get this deep cycle battery and for how many hours will it last? |

Inverter?? I bought one 1.5kva like 3years ago, when it was not lasting up to 2hrs I had to dump it somewhere. I think the problem must have been the batteries. I will call a tecnician to check it now. |

Thanks guys . . i'm thining of buying an inverter for my parents - they have two generators at the moment . . too much noise and pollution. So basically, the output of an inverter depends heavily on the battery capacity as well? mabe one should invest in those batteries used in trailers and the sorts? how much is a 5KVA inverter on the average . . and what kinda load can it carry? |
Re: Inverter Users : Lets Have Your Experience by kokoye(m): 6:16pm On Jun 08, 2011 |
and is there no way of assembling these inverters in Nigeria?? when i lived in Nigeria, i had a honda generator that used both kerosene and petrol - I used it for over 3 years before I gave it out. It was assembled in Nigeria . . no problems whatsoever. All i had to do was change the oil regularly I really dont believe we need to import these things ![]() |

Re: Inverter Users : Lets Have Your Experience by Nobody: 6:43pm On Jun 08, 2011 |
Olawoye: As an experienced Inverter Engineer, I'd say in reality that you don't require up to 5Kva Inverter. All you need is a 3kva inverter if it is the same regular house electronics that you have, as in my quotes above. 1 Like |

Wanna use an inverter at home then I guess you have to follow all the analysis above. Just want to add to these though. 1.5KVA Inverter+100A battery-> Powers 14'' LCD/LED TV, DSTV, 3 Energy bulbs(Phillips, Electrolux(I especially love these bulbs because they have sunlight sensors(Check GAME)) & OSRAM), 1-2 Ceiling fans. Duration-> 3-8hrs depending on usage. If the technician u hired is good he can construct something better so as to be able to connect more batteries for longer usage as well as shorter charging time. More like boosting charge time. Some technicians aren't that good so I'll leave you some tips. -Buy a 5KVA stabilizer, connect the power source(NEPA) to the inverter. Never use the stabilizer with a generator. -If u have some additional cash you can go for a solar panel and a solar controller -Setup the inverter and batteries in a cool place that's devoid of a damp humidity. Also, avoid direct sunlight on the batteries. -If you have to use a fridge or freezer or A/Cs then makes sure these come on 1st b4 others because these require extra power to startup. Now for a 3KVA Inverter+4x100A battery)->Powers 32'' LCD/LED TV, DSTV, 6-7 Energy bulbs, 0.5 or 1KVA A/C or a table top fridge or freezer, 4-12hrs depending on usage. Some more technicality, if u wish to connect the inverter to the entire flat then u must use an AVR for A/Cs, Fridges, Freezers etc & set the timer to 5mins. Furthermore 5mins can be enuf time to switch off the 25A fuse on the fusebox. Quick calculation on the load terminologies. KVA->Kilovolt x Ampere which is power (Watts) so more like KiloWatt. 1KW=1KVA. Before U use anything check the manual for the power requirements. The reason why NEPA charges faster is because NEPA supplies increased voltage and generators do not. To boost NEPAs voltage use a stabilizer. 8 Likes |

Re: Inverter Users : Lets Have Your Experience by infohenry(m): 12:33am On Jun 09, 2011 |
This what you need to increase your inverter battery life span Never allow the batteries to drain completely before charging. Check the date of manufacture before buying most batteries have a life span of 4yrs for dry cells and 10yrs for wet cells so when kept for so long in a shop you might end up buying a dead battery that can not retain charges. Keep the batteries at a temperature range of 16-22 degrees celsius for optimal performance. Make sure the battery terminals are firmly secured to avoid leakage leading to local action. keep the terminal lubricated with vaseline or any jelly. Never increase your inverter float charge more than the manufacturer preset. I believe most inverters are good the problem users always have is the battery but the best inverters are the full sine wave inverters they deliver distortion-free voltage to your appliances like ups. 7 Likes 1 Share |

Inverter only converts dc current to ac current while battery is the energy bank. Ur battery determines efficiency ur system. Good system will not let you drain ur battery beyond 50% SOC or DOD so as to prolong the lifespan of ur battery. There is a saying that batteries dont die, they are murdered. Whether a battery will die after 6 months or still be strong after 6 yrs depend on usage. The secrete is that u dont overcharge and dont overdischarge ur baterries. 1. Dod (depth of discharge) should not be more than 50%. 2. Go for system that takes the charging through 3 stages (Bulk, absorption & float). 3. Go for system that will stop the passage of current to ur battery when it is full. 4. Dont leave ur battery at a discharge state for a long time. Here are no-load typical voltages vs state of charge State of 12 Volt Volt Charge battery per Cell 100% 12.7 2.12 90% 12.5 2.08 80% 12.42 2.07 70% 12.32 2.05 60% 12.20 2.03 50% 12.06 2.01 40% 11.9 1.98 30% 11.75 1.96 20% 11.58 1.93 10% 11.31 1.89 0 10.5 1.75 A perfect alternative energy solution will always go with solar power as it ensures everyday charging. The only problem here is that imported solar panel are still expensive (N550-N800 per watt) and the good news is that you can buld it yourself at a very low cost. All panels I built 3 yrs ago are still performing at optimum level. If you dont mind spending big, go for imported panel: you will love it. 4 Likes |

Re: Inverter Users : Lets Have Your Experience by Reference(m): 9:45am On Jun 09, 2011 |
This is the thread I have longed for. So many important point. Prior posts we had the sole views of sellers most of whom didn't know what they were into. Now we have the views of genuine Nigerian users and this has helped. What is left is the picture in perhaps the long term particularly as it concerns cost efficiency. For the careful users where the costs of the batteries is over 50% and are more or less the disposable parts of the system what would be cost profile in the ling term. This can help those who want to establish larger scale systems and intend to use it for primary source of stable power and not just as a back up system. Secondly to help most Nigerians it is equally important that local technology and manufacturing know how improves. For those experienced in this field have you noticed a closing or widening quality gap between top end foreign imports and top end local products. I would like to know. However one good thing about all this is that some Nigerians have adopted good conservative practices. Batteries are not eco-friendly by any stretch of the imagination but those power hungry filament bulbs and massive CRT tv's are worse. Anything that can hold forth to suppress generator running times is highly welcome. |
Re: Inverter Users : Lets Have Your Experience by Eltneg: 9:47am On Jun 09, 2011 |
I use the Nascent brand of inverters supplied by Nascent Solutions. The Inverters have the advantage of a modified charging system that supplies more amperage to the batteries so that they charge better. I hear that cyberpower inverters usually have issues with charging batteries very well. I don't know how true this is. The company also installed the inverter in my house such that it works as a UPS for my house. When NEPA is on, the inverter is charging. When NEPA goes off, the inverter automatically comes on without a blink. The TV, Lights and other appliances whose sockets are wired to the inverter continue operating as though nothing happened. Since the AC, fridge and iron are not on inverter, they automatically go off when the inverter is powering the house. Really cool. . . I can work from morning to night without having to stand up to go and change power ![]() Nascent Power Solutions 08034827197 2 Likes 1 Share |

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 femi on 08033681445 josfemi@yahoo.com BB 2960E531 5 Likes 1 Share
