microgiant: Yeah I do have a few cells for sale though I don't consider myself to be a cell dealer but if you believe that is why some of us here say these things about lithium that's also fine, we all should not have same opinion. 2 Likes |

While Lithium remains the superior chemistry, let us not bash lead acid tech so much that we begin to put out incorrect info. First off, all lead acid chemistries are not the same. As far as I know flooded batteries can safely accept charge at 13% of capacity so a 200Ah battery can take 26A easily with no trouble, AGMs can easily do up to 25% of capacity so your 200Ah AGM battery will take 50A no trouble. If you are sized for typical 50% DoD then it should be possible to fill up your batteries in one solar day keeping within safe limits. Not to forget also that ideal sizing for offgrid lead acid battery is 3 to 5 days autonomy and if you are so sized, C rates stop being a problem. bigrovar: |

Indeed the SG readings are only half of the story. I had a US Battery bank - 16pcs of 6v approx 400Ah that ran beautifully for 18months plus before they croaked - I was charging them at about twice recommended amps. The SG readings will be fine but the plates inside the battery will wear out and the battery start running hot (electrolyte boiling). As Jesus said in the good book 'when you see these signs then know ye that the end is nigh' To use lead acid and especially flooded successfully, you have to oversize the battery bank relative to your average needs Namzy: 1 Like |

[quote author=bigrovar I love your submission. This is exactly the strategy I'm using with my 4 x 230ah tubular battery. I've 100% confidence of making greater use of my battery while hoping to join lithium club in the nearest future. Then, every controversies about it must have put to rest and the price must have come down. Happy Easter Solar Enthusiasts. |

Re: Solar Energy, A Complement To FTA by Namzy(m): 8:07am On Apr 15, 2022 |
dollarnaira:Lol obviously my panels can't generate 100amps and my loads also take up some amps as well. The highest I've seen from my monitor charging the batteries is about 45amps for luminous tubular 220ah and mind you with that amps I get to absorption faster which will drop said amps. Also the increased amps charging are for days my night loads are heavier than usual and the morning after has adequate sunshine, which isn't all the time. So I believe this 'experiment' will last a long time. Fingers crossed |

Re: Solar Energy, A Complement To FTA by mctfopt: 3:29pm On Apr 15, 2022 |
Valto: Used cells are so much in China market. They just rebadge the cells to look like new. That's why when chatting with them sellers, my first question is usually "it's this fairly used or never used?" Of course the price they are selling gives you an indication when it's "fairly" used. Some scammy Chinese sellers will still tell you it's new when it's not. But reading reviews helps in that department. 1 Like |

NiyiOmoIyunade: Absolutely, if you note I was referring to Tubular which seem to the the fad these days. Yes AGM has higher rate of charge discharge compared to Flooded batteries like the Tubular type. In fact in certain situation I do recommend an AGM battery over Tubular for this very reason. The are the closest to Lithium in terms of charge / discharge rate and efficiency. |

As part of my system upgrade, I decided to use my Ipowerplus 5kva Inverter as a second charge controller and terminated the new array of 2kw to it. I would never have done this before now but I had to keep things within budget. The axpert MKS series of inverter which the Ipowerplus, Gennex and likes are based on has a known bug MPPT Bug which causes the inverter to switch to float early under certain conditions. The bug pretty much makes them completely unreliable and not fit for purpose because it has the potential to damage your batteries leaving it under charge. In my research I noticed that the community around the axpert series released a custom firmware which fixes this bug and add more functionality to the inverter. One of the functionality is add is to make it more compatible with Lithium battteries. I flashed my inverter to these firmware and the result has been amazing. You can read more about this firmware and other important information about this type of inverter here https://forums.aeva.asn.au/viewtopic.php?f=64&t=4332 3 Likes 1 Share |

Good evenings, my inverter makes a buzzing/cracking sound inside anytime I put on my Panel breaker.. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:24pm On Apr 15, 2022 |
As a first step, check that all connections for PV, Battery and AC within the inverter are securely tightened - you want a firm mechanical connection but do not overtighten! myrax7: 1 Like |

bigrovar: Yeah that old bug has been a pain, wonder why this has not been fixed with company firmware till date. When I used the MPP GK series I had this issue, unfortunately only the MK series (low VOC) had the custom firmware. My work around then was to use the SOC figures from my BMV to automatically control when the inverter should switch to float. It worked pretty well |

Thanks � for the wonderful post being made to save this thread, if you might have noticed another solar thread on nairalabd is practically a sales thread no more contribution from other solar enthusiast anymore. This thread seems to be the very last,with volumes of knowledge. I learnt a lot and still learning. Let us try and keep the flag up. 3 Likes |
