Hey guys please I'd like to know how I can know the difference between a good lifepo4 battery and a bad one. since most of them in the market right now second-hand how can I tell which is durable and will last longer which one is has been used for a long time. |

pls how many pv volts should 580w give me? |

Durable

ceaser: yep, I thought so too, not until the charger input socket melted and the wires became hot. when I opened it up, the charging board was burnt. one diode there was roasted. Lol when I saw the kind on soldering done inside,I just held my piece. we are in Nigeria! a friend who had the same zinox bank, used his for 3yrs before the backup times reduced. different strokes for different folks I guess |

eleojo23:Nah. they are reliable though. |
Re: Solar Energy, A Complement To FTA by eleojo23: 8:21am On Aug 23, 2019 |
zeestone99:So, which is the best? |
Re: Solar Energy, A Complement To FTA by zeestone99(m): 8:43am On Aug 23, 2019 |
eleojo23: Can't say there is any best, but there are durable brands out there, it all depends on how we use the batteries. Some are susceptible to abuse than the other. That doesn't say we should expect anything good from cheapo chinko batteries lol |
Re: Solar Energy, A Complement To FTA by zeestone99(m): 8:45am On Aug 23, 2019 |
Use of Mc4 connectors. We should endeavor to use Mc4's so we don't have reduced output overtime. The pix below tells what happens to your cables overtime. Order your Mc4 now o. Don't say i didn't tell you. Just 800 per pair pere. 2 Likes

sintolord: here's a rough depiction of what i have on ground. please never mind the hand drawing. replicate that in 3 places to represent each of the three strings and connect each string to a single bus bar. so i have 3 positive cables and three negative cables connected to my inverter through the bus bar. and very importantly, each cable having equal length regardless of distance from battery bank. so essentially, it's three independent banks operating as one. same charge current, same discharge current from each string. hope this helps? 3 Likes 1 Share

Wow!!! You were lucky this didn't result in an explosion/ fire incident. I'm not sure your wife would have been composed enough to handle it. It's best we take seriously the issue of safety as advised by the boss himself @Niyiomoiyunade not just for us by for our family members who are just excited about having continuous power and don't understand the working of a renewable energy system. My first lesson in Electrical Engineering in my undergraduate days was this, "Electricity is a good servant but bad Master". This was accompanied with gory stories of people who lost hands, limbs and even life because they didn't consider safety first in their dealing with electricity. So like Boss Niyi said, safety 1, safety 2nd and safety 3rd... olaolu11: |

zeestone99: Now I'm seriously having second thoughts about DIYing those lithium I have stored up. First I didn't even store them in the main house but in a shed outside. Second, they are all neatly arranged inside a nylon wrap (in fours), no metal shrapnel or screws are located anywhere near it. Haba! Na wa for Lithium o. If I will go ahead with the diy pack, I must first get a welder to make a metal container and na for inside that I go put am. I cannor come and be having heart attack. |

ceaser:I think that ur battery has BMS in it. Just don't charge above 14.6volt are good to go. |
Re: Solar Energy, A Complement To FTA by lexi28(m): 9:51pm On Aug 23, 2019 |
olaolu11: 2 methods exist: use a battery analyser or a battery tester which applies a heavy load across battery terminals for like 10secs. some will advise the high current draw be maintained a little longer than 10secs. I doubt however that your battery supplier will want that, as most never charge their batteries in storage before they are sold. some companies will stamp a manufacture date into the battery case itself, you should look for that, then ask for a load test be done. that should be better. You could decide also to search for the main dealer of a battery, who has a return policy and a warranty longer than 24hrs. |

I have two questions 1. Can 400ah battery power a 1.5hp inverter ac for a period of like 4hrs? 2. Can one combine 2 batteries of different brands with the same voltage to get more amperage? |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 10:55am On Aug 24, 2019 |
idris4r83: 1. 400ah @ 2V NO 400ah @ 48V YES 2. NO |
Re: Solar Energy, A Complement To FTA by idris4r83(m): 11:33am On Aug 24, 2019 |
Dam5reey:u mean 400ah @ 12v? |
Re: Solar Energy, A Complement To FTA by adrusa: 11:40am On Aug 24, 2019 |
idris4r83: 1. It is possible, but I won't bet on it. The higher the discharge rate of a battery the less the AH that can be taken out of it. In addition, depending on the cut-out voltage of your inverter, the inverter may cut off before the battery even get to 50%. 2. Yes, it is possible, but not recommended since each battery may have different charging characteristics and internal resistance. In reality, many people are constrained to do this for logistics and cost reasons. Using a balancer may help alleviate some of the side effects of combining dissimilar batteries. |

@chris @niyiomolyunade and other DIYers Can an mppt controller be fed with a regulated DC supply? I have read conflicting ideas on how it will perform. Some say the algorithms that mppt devices operate with may cause it to self-destruct or destroy the power supply. Others say it should work as long as the the power supply has some current limiting feature in it's design. There isn't any practical video or article about it i could lay my hands on. So what dyu guys think? And anyone who has an mppt controller that they don't mind sacrificing for science I'll like to see a practical demonstration of such connection. I dnt mind collecting and carrying out the experiment myself if the donor prefers it that way. |

Trippledots: There are cheap mppt controllers on aliexpress. You can get one and try, if no one is willing to donate. 2 Likes |
