Sorry, have you tried loading it beyond the previous one? may be this new model has advance transformer 1 Like |

JUO: It has a different display that the other one, and flunctuations in input voltage at at given time makes it difficult to compare.the old 10kva has 25%, 50% 75% load graduations, while the new has 10%, 20% to 120% 2ndly, i opened it up, and its same sized transformer in both of them!.A 5kva increase should have a significantly larger transformer. Its good am within the 7 day purchase window, will kukuma return it and get my money back. Bought my original 10kva 50k back then.present day 10kva is 110k, while the so called 15kva is 160k |

ojeysky: Day 1 with lifpo4. My night loads was the same (or even more because I did put on my 1.5hp GenPal for about 20min) and I still have 26v reading on my display. It outperformed my lead acid significantly as I will be at 24.5v if it were my 300AH lead acid. In other to reduce the long speech I think the attached picture should summarize the difference between lead acid and lifpo4 experience and you may see my signature for more detail log reference. Perhaps it's just a coincidence but it seem my system efficiency was better. Including temperature of inverter. I am wowed! with just a day performance that I have experienced with this thing and I am wondering if this will continue in months to come. Whether 4 quanta will have given me the same experience is what I don't know but one thing I know is that the weight and space of a quanta alone na worry. How I got mine: Meet with a guy remotely who deals in lithium. So he coupled for me 16 EVE LF105 to make 24V 5.4kwh (actually nominal is 25.6 as each cell is 3.2V) and ofcourse it comes with a BMS and voltage indicator. Price: 450k - I checked price of the cells and estimate cost of materials he used to conclude that it was a fair price. His contact is on the battery sticker but you may also PM me if you like to have his details. He was quite professional with me though I have not meet him physically before but took the risk. 9 Likes 1 Share

ojeysky: What's the weight of this battery? Can you type out the contact as it's a bit hard to read off the picture? Thanks. Impressive performance � |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 7:59am On Jan 21, 2020 |
mctfopt: I have not put it on a weigh yet(will do that later today) but it feels like a 40 to 45kg pack. FWIW each of cells is 2kg and considering the materials used for packaging anything from 38kg is fine. 8 0 3 063 3202 For now yes but time will tell |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 9:13am On Jan 21, 2020 |
Bulk is essentially a transition state on the way to Absorb and then Float. There is no one voltage where your battery is in bulk but rather a continuum e g if you set your Absorb target at 14.4v and Float at 13.6v your battery will be bulk charging between 14v and 14.39v. You can think of Bulk as the road or journey as your battery travels towards a full charge, Absorb as the period when you glimpse your destination closeby in the distance and you move towards end of journey with renewed vigor and Float as having arrived your destination and now taking a rest. For your A&E experience I would say again you are always better off buying direct from source and bypassing the middleman - I say this even though I retail RE equipment ![]() earthrealm: viazi: 3 Likes |

NiyiOmoIyunade: Did you mean 12v at bolded? And yes your illustration is apt as usual. The way i see it is this: Bulk- constant voltage supplied with max current drawn Absorb- constant voltage reached, max current steadily dropping. Float - constant voltage reached, max current reduced to a set tail current value. So voltage dropped to set value and current trickled in to keep things nice and full. ![]() Float light on scc de give orgasm ehn.. IYKYK ![]() 3 Likes |

Re: Solar Energy, A Complement To FTA by Barezzi(m): 9:35am On Jan 21, 2020 |
The bulk charging phase(constant current) is when the battery charger pumps maximum current into the batteries until the voltage rises to the Absorb value. It then switches to the Absorb phase (constant voltage) where it holds the battery voltage constant for a certain time limit or until the charging current drops to a percentage of the battery capacity. I have mine set to 2%. At which point it changes to Float phase and drops the voltage to the "Float setting" and trickle charges to maintain that set-point. earthrealm: 1 Like |

DUNKA: Good morning Sir , yes guess you're confusing all due to short memory ! The last deal before said car battery supply was your outback mate system supply. Battery spillage et al must be transportation issues but it's all well ..

Re: Solar Energy, A Complement To FTA by Barezzi(m): 9:57am On Jan 21, 2020 |
@bolded, I'm not sure you should be swayed by the difference, as it's not a true indication of battery capacity. While Lead-acid battery voltage will sag under heavy load and Lithium remain fairly constant, the energy consumed should remain the same. 5kwh Lead-acid useable capacity = 5kwh Lithium useable capacity. I believe why you witnessed an improved performance is because of the higher Lithium "useable" capacity. ojeysky: 1 Like |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 10:09am On Jan 21, 2020 |
No I meant 14v to 14.39v in the specific example I gave. Battery charging may be considered to be an electrically driven chemical reaction - a typical lead acid battery is not really charging properly until it has entered the 14v range. Oga Barezzi gave a precise technical explanation of Bulk (constant current), Absorb (constant voltage) stages - this tends to be more easily demonstrated with an on grid charger which puts out steady amps and volts than a solar charger where the current and voltage output may dance around with prevailing weather and clouds.

If my experience with the yellow Luminous is anything to go by, it is best to jettison the battery bank now or seek a warranty replacement if still under warranty. The problem with a replacement is that you are probably still getting thesame crappy batteries and postponing the evil day. kiekie1: 1 Like |

I see some drafting forgotten issues like they were admin, moderators or even old members but all are fallacy to me ! Ask him as a man why he acts like a woman , how much do I owe him, you will hear nothing ,, pls let him rant in vain..DStv,gotv ,swift etc keeps calling & bugging if you don't subscribe for a while but they won't talk or make noise .. Phcn has lot of unappealing issues but they won't go query them ,and so many other irregularities in our decayed system ..

Barezzi: Yes I agree it's not a true indication, I tried to use the daily battery discharge(see attached picture earlier shared) and the voltage to correlate things as well. Meanwhile is there any better(close to accurate) way to determine true capacity of batteries? Thanks |
