earthrealm: 1. Charge Controller is victron blue solar Setting is 54.4v for float and 58.6v for absorb Inverter setting is 54.8 for flair and 58.7v for absorb. The batteries are mostly charged by solar Attached is a screenshot as at this morning. There was lite all throu the nite so the batteries were on float. 2. I have been using HA02 for years maybe I should try another balancer as u suggested. 3. Ok will consider that. I have several fridges in the house will connect it to a timer switch.

nonoski: Sorry for the loss... It's a very big one. Though since this Luminous Blue came out, I've only been hearing bad reviews for it. Their yellow mode was a little better. As a matter of fact, a Solar Company here in Eket carried out a capacity test on the Luminous blue and got about 87%.... Very poor I must say. I also know a boutique that is using 1.5KVA/24V Sukam falcon plus with the Luminous blue. Loads are just the lights. No fan sef, just lights and they have never drained it to alarm level. After 9 months, another story... And two or three other negative feedbacks from users. I've been discouraging people from going for this Blue model I believe it's a factory issue. Same thing that happened to PRAG battery sometime. After they modified their battery and it started have early failures. I might not be able to suggest the best battery, because I've not actually used or installed all. But Over 5 years now, the two batteries I can vouch for are Quanta and Safepower.... Both are Indian From Chinese angle, I've also come to trust Mpower (distributed by AirWave Ltd)... I do use them for clients on low budget. All the aforementioned are from my personal perspective. As for batteries always being on float charge posing a problem, to me it's a fallacy. As long as the float voltage of the charging source (Inverter or PV) is within the recommended voltage of the battery manufacturer. For example, almost all inverters have a default float voltage of 13.7/13.8V. But Quanta strictly recommends 13.5V as the float voltage. So question is what happens when you have Quanta batteries that are being subjected to constant float voltage of 13.8V? These days, people just randomly choose Inverter and batteries without any form of regards to conformity and compatibility. Finally, looking at your setup, it can be seen that your battery arrangement calls for long battery interconnecting links at some point. I hope ALL the links are same length and same size. Not that some would be short and others long... As for the Battery balancer, if it's HA02, then I believe it shouldn't be a problem. Unless it's all those Sukam and few other "unbalacing" balancers. Once again, sorry for that heavy loss. 12 batteries no be beans, even if you're Chevron manager ( lolzzz) Cheers 5 Likes |

mcTrinity: Thank you very much Coughing out N1.4m for batteries is not funny at all. I double checked the set voltages so over charging is not the issue. The charge controller is premium brand Victron and the inverter is Felicity. I have used HA02 battery balancers for years without issues. The 3 units of 4 batteries are connected to a Busbar so the Lenght of the wire (35mm²) are of the same Lenght. I have made up my mind to change the batteries. |

nonoski: Really sorry for your lost sir! It's quite unfortunate, but like the white guys say "shit happens sometimes" Maybe it's time to go lithium iron phosphate known as Lifepo4. I stand to correct you that Lifepo4 is one of the safest amongst the lithium battery family... You can do more research and find out for yourself. The beauty of it is that you don't need to connect several batteries in S and P but have a single unit built to you voltage and capacity as well built according to you application. There's always a first time and we already have guy's within this forum with good knowledge of it. |

grafikii: Using a 12v system and assuming a 200w load, you will need 1. At least 2 units of 200ah batteries (roughly 200k). 2. A 1kva inverter (price varies, contact the sellers on this thread for a quote.) All things being equal and excluding solar, 250k should get you the setup you need. That is, assuming that all the appliances are turned on for 12hrs non-stop. But if they will not all be turned on at the same time and money is a constraint, you can manage with one 200ah battery further reducing the cost to say 150k or thereabout. 1 Like |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 2:29pm On Jan 20, 2020 |
ceaser: So did you set both your float and bulk to 13.9v since lithium does not really use the float or bulk options? I currently have my float and bulk at 28.6 and 28.8 respectively. Just trying to figure whether to just put both at the same voltage level |

Re: Solar Energy, A Complement To FTA by Dam5reey(m): 4:40pm On Jan 20, 2020 |
Abeg, In conclusion we should use MC4 connectors or Just cut and join wires? I'm thinking of MC4 connectors oo, I remember when my panels were producing less power, I had to rejoin the wires after the wires on Yachi panel became Rusty and burnt, but the Yingli panel with aluminum coated remain intact no sign of rust at all.. |

Re: Solar Energy, A Complement To FTA by mcTrinity(m): 5:51pm On Jan 20, 2020 |
Dam5reey: MC4 is a good option, provided it's a good quality one. Personally, I do use a kind of terminal connector shown in the picture, as long as it's protected from any weather condition (rain or sunlight). I can easily screw and unscrew cables in it... And I normally, after testing and commissioning, still properly cover/seal up the open ends of the connectors Cheers

grafikii: If you will be using only one battery, make it 500w-600w for faster charging. 300w will do but it may not charge the battery fully before sundown. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 6:37pm On Jan 20, 2020 |
I strongly agree - however try very hard to get a decent quality MC4 fom a reliable source and ensure it mates tightly/firmly with your solar panel's existing connector. An el-cheapo will only cause stress and pain in the long run. Oshomo12: Dam5reey: |

Re: Solar Energy, A Complement To FTA by JUO(m): 7:18pm On Jan 20, 2020 |
There is believe in this forum that DOD does not affect lithium, this is not through. There is no battery that DOD does not have effect on. If you check lithium battery datasheet you will observe the graph decline from 100% DOD to a lesser number of cycles. Even higher charge/discharge have effect on the bms. Some will state 100A charge/discharge and at the same time put a recommended charge/discharge. Please note I am not saying lithium is bad in fact I will have 100ah/51.2v/5kwh and 12v/100ah/1330wh soon so if interested contact me |

Re: Solar Energy, A Complement To FTA by simydan(m): 8:56pm On Jan 20, 2020 |
JUO: Sometimes buying from these Chinese guys can be very tricky, the smallest difference in price can make a very big quality difference. I noticed that sometimes they pack lithium ion cells and call it LFP as well I've once gotten an offer for this kind of battery pack at $120 for 12v 100ah while the packs that are build like the normal lead acid pack cost twice or more for same 12v 100ah. Substandard cells and cheap BMS can lead to the swelling of the battery. For all I know the Chinese will always give you what you pay for and for those who don't cut standard, it will always be difficult buying from them due to high cost and sometimes not willing to offer smaller units. Still would like to know the current state of the battery now. ![]() |
Re: Solar Energy, A Complement To FTA by DUNKA(m): 8:58pm On Jan 20, 2020 |
nonoski:looks a like an Axpert clone branded under Felicity. Those inverters charging parameters do not give it a true and proper 3 stage charging of bulk, absorbtion and float. The behave more like bulk chargers. Before you go for the change of all your batteries you may look at the inverter you are currently using. Regards |

nonoski:@bolded seems victron and by association dont include bulk voltage setting in their devices, only float and absorb.. How or what then does the battery use as bulk voltage when charging. I have a fangpusun 50aD and the lack of bulk voltage setting is giving me concern, exchanged series of mails with seller, no resolution. For batts like kung Long batts, whose recommended cycle voltage is 14.4v to 15v and absorb 13.5v to 13.8v, How do you set the cc to charge at the bulk/cyclevoltage, since the cc/inverter doesnt recognize/assign charging voltage to bulk charging state ![]() Talking about marketing fraud, i just fell victim to A&E dunamis 15kva servo stabilizer. I have a 10kva of same make wch has served me ok for over 4yrs, but due to increasing load, i decided to upgrade to a 15kva. Ordered same via jumia. Lo and behold its same size as my former 10kva, and even same weight when i put it on the scale!!...choooi a&edunamis, but why ![]() ![]()
