gadgetplanetng: Thanks @ gadgetplanetng for your response. My load is fine during the day with... - led bulbs = roughly 45w - Tv and decoder = roughly 130w - Refrigerator = 110w - Washing machine = 500 - 600w - Fans = roughly = 120w - the inverter itself = ![]() The solar do take care of these load during the day and still charge the battery full before 12noon. My night use is mainly lights (50w), fans (60w) and phone charging. Total of roughly 150w Less I forget, I run fully on solar i.e off-grid. I only switch to Nepa when fixing things on inverter system or once in 2 weeks to allow inverter to rest for a few hrs. Only my pumping machine and bathroom water heater is directly on Nepa/gen. Also my soelix inverter is 24v and I will be considering 24v LiFePO4. The inverter has a battery setting to select either smf or tubular, the main reason why I am in doubt if it's compatible wt Li battery. If monitoring means just using the corner eye to check the reading while passing, then this is fine. |

kaziem: If the inverter doesn't charge the battery then that doesn't matter. What matters is the CC and if it has the adequate settings |
Re: Solar Energy, A Complement To FTA by kaziem(m): 3:11pm On Dec 21, 2021 |
gadgetplanetng: Thanks for being there. That means I should not bother on the Inverter since I am not charging the battery wt Nepa. Attached is the pics of my CC, I wish it is compatible wt LiFePO4 charging. Also, I am looking at that tactel LiFePO4 brand like the one adrusa bought. I am also open to any reliable brand. I will also appreciate advice from other experts please... 2 Likes

Let's assume you 1. Plan to charge with grid and solar - your inverter will charge your battery at bulk/absorption but at float it won't make sense to charge with it being a pre-program parameters Seek for an inverter with editable parameters or continue to use your inverter but never use grid to charge since you don't plan to monitor 2. Assuming your charge controller is editable, your panels is enough to charge your batteries without loads 3. Since your loads is unknown in your quote, it is safe to assume it abides by 50% DoD of your LA Batteries else you might undersize for the lithium battery too 4. LiFePO4 is a safer chemistry over Li-ion so there is little to zero chance of explosion while charging 5.if yoir battery is built with a good BMS then you only need to install and forget while focusing on productive activities kaziem: 1 Like |

gadgetplanetng: Please when dealing with batteries never say you will do away with charging especially with nepa. It is always good once a while to charge with nepa or gen. The voltage is constant. If you can't fix the inverter get an external charger. |

I always thought solar charging was better for batteries (especially LA) and Charge controllers ensure a constant voltage to the battery samnaija: |
Re: Solar Energy, A Complement To FTA by samnaija: 3:52pm On Dec 21, 2021 |
gadgetplanetng: Controllers cant guaranty constant voltage, cloud effects , bad wheather and so on. You can carry out a little experiment charge with nepa only and discharge, also charge with controller and discharge. You will notice a difference in run time. The rule is once a while charge with nepa 1 Like |

gadgetplanetng: Thanks so much especially with the fact sheet. |
Re: Solar Energy, A Complement To FTA by kaziem(m): 5:31pm On Dec 21, 2021 |
olopan: Thank you for your input @ olopan. I am actually not thinking of charging my system wt Grid/Nepa but following what samnaija advised, I can make use of external charger for the proposed LiFePO4. From the CC fact sheet, I think its parameters are customizable. I am actually considering LiFePo4 of 24v 200Ah or 5kw capacity so I feel I am not undersizing. Now talking about LiFePO4 with good BMS, this is why I need advice on good brands. How is tactel, Max, Felicity (low trust) or .......? |
Re: Solar Energy, A Complement To FTA by kaziem(m): 5:34pm On Dec 21, 2021 |
samnaija: Thanks for the advice. I agree with you on this. |
Re: Solar Energy, A Complement To FTA by olopan(m): 5:58pm On Dec 21, 2021 |
Then you need to upgrade your panels to produce more power; attached is power production of a typical tier 2 panel I don't know much about the batteries you listed but I am sure many others who use it can give a better insight kaziem:

samnaija: bro, you might want to check the veracity of your statement again. what the cc can't guarantee you is max current output for a given voltage range all through the day. it can certainly guarantee you steady/constant voltage for the greater part of the day while the sun is up except for an exceptionally cloudy/rainy day. also, its not a rule of thumb to charge your battery bank with public power or nepa/phcn. some of us here have been off-grid for years now, only using the sun to charge our banks and our systems are doing extremely well. it depends on the size of your solar array and cc quality among other factors. 6 Likes |

GeorgeD1: I stated cloudy day and bad wheather, which was very common in Lagos for the past 5 months. It is just this month December we are getting clearer skies, but dusty panels with harmattan. And George majority do not have over sized solar array like you . You make do with what you have, when there sky is not clear it is no brainer for you to use nepa or gen to suppliment. 2 Likes |
Re: Solar Energy, A Complement To FTA by kaziem(m): 7:32pm On Dec 21, 2021 |
olopan: Thank you for the input. I will observe the output of my solar array if it needs more panels. Please experts, I still need advice on good LiFePO4 battery brands with reliable BMS. |

GeorgeD1: I've had Chinese living in far away China honour the warranty they gave. One even honoured it after 18 months in a 2 year warranty that I thought was one year ![]() Most people in Nigeria find it extremely difficult to honour warranty. It becomes extremely difficult to truly believe their warranty claims as they mostly will not hold their end of the bargain when things goes south. I understand some solar product marketers may not know much about the product they are selling, but that does not in any way exempt them from giving a warranty claim and reneging on the same promise; that's fraudulent. 7 Likes |

samnaija: Is the buyer not supposed to trust the word of a Seller, about what the seller is selling? "If" the Seller says there is One Year Warranty, is it the buyer that should say that is a lie or l dont trust what you are saying? The reason l am asking is that l always trust what a Seller on this FTA thread says abotu what they are selling, as l often think we are here to help one another, with knowledge and business sales. I wont be happy if we are turning this thread to "Alaba Boys will just eat your money", or is everyone trading from Alaba now a Crook? ![]() 5 Likes |

smallsmall: Of course you are right. The onus is on the seller to make a claim that he can and is willing to fulfill and the buyer traditionally has to believe that. Although you can further reinforce your believe with one or two researches on the person or item. See, in my quest for energy saving devices, I came across this infinix android TV (I went scouting for Samsung or LG) but when I saw an android OS powered offering from a popular manufacturer, I jumped on the wagon and purchased a brand new infinix android TV with one year warranty. That was October last year. By August this year, it begun to act up. A web search revealed tens of people on Nairaland having the same screen problems which means it wasn't any fault of the user. I visited the shop where it was bought armed with this information (a very big and reputable outlet at that) and all they could suggest is to give me the number of their electronics repairer to call so he can help me repair it. Of course I trashed the idea as useless in their presence and warned them of possible grave consequences if they won't do the normal thing (I have my ways). They eventually agreed to collect the TV and take it to infinix office in Lagos with a promise to contact me later. What I try to point out here is another instance of bad attitude of sellers trying to push the responsibility for repairs on the buyer when items is still within warranty and when the fault is clearly not the buyer's. And while you may have had this unsavoury experience with merchants on this thread and possibly many more will act the same way if exposed to such trial, I can vouch for one person here who honours warranty. That battery guy in Jos is one person. A pack I bought from him acted up within one year (quick discharge issues) and I contacted him. He simply responded that I should have it sent down and he assuredly added that at least my cells are under warranty so replacement is no problem. I'm still looking for a way to have it sent down to him. Once before, he has also replaced for me a battery that got damaged during transport with a new one which he now sent using a more careful driver. The guy is also on this forum, so not every vendor has that attitude at least. There is even another battery guy (not on this forum) with similar issues with a client I referred to him. He asked I send down the battery, he will do top balancing and then promised to add an active balancer all for free. smallsmall: I believe GeorgeD1 already gave an answer to this. smallsmall: @bolded. Sadly, we can't take the security agencies to go arrest the guy. The best that can be done is to encourage him to try to preserve his reputation and we also use the "threat" of withdrawal of future patronage or referrals to coerce him to do the needful. It's a faceless forum and if it happens to be someone who is shameless and doesn't give a shyte, then I'm afraid all those "threats" won't matter. But I want to believe JustCallMenuel is not that kinda person. I want to believe he will come thru with a solution that will make you smile at the end of the day. But remember to give feedback here if and when he does. It's too bad and hopelessly annoying, I tell you. 2 Likes |

smallsmall: Please do not trust what the seller says. Research and do your independent investigation. Which Alaba seller offers warranty and honours same? I haven't seen any.Even with reputable companies,you have to battle to enforce your warranty in Nigeria. Most sellers here are just 'baranda' people.They have no idea of the products.They just go round ,take pictures. And like most people have stated,most of all the solar lamps are not reputable.We all know the good brands but most times we run away because of price.I recently bought SMS 150 solar flood light some 2 months ago for 27k each.I saw other brands for much lesser price but I knew they can't last. Good products are expensive these days so what our guys to us to bring in sub standard ones at attractive price.I was speaking with the sales manager of proton power systems recently and she said even the cost price of a good 200ah Lead Acid battery from China is well above #100k and you see people here posting batteries for 100k,115k and you expect it to be good.I have had my own share of their dishonesty so I do my research and go to the company/importer direct whenever I need anything.It may cost me more buying directly from company but at least I won't gey fake!!! 2 Likes |

ewizard1: On my remote it is written 2 to 6 hour if u set it. but if you leave it on induction , it will come on at sun down, 6.50pm and by 2am it is off battery dead . So what I do, is on some then by 11pm switch it off then on others to morning. Most don't don't last 12hrs at a stretch at least my own and my neighbor. But because of my experience in solar I don't let them get depleted like my neighbor, that is why Mine is working while all is own has packed up 1 Like |
