Have you tested any batteries in the real world? I have tested several and even have an algorithm for determining battery capacity within 10 minutes of a large load being applied based on the voltage sag behaviour. This tester you all use for support appears ignorant of proper procedures (see earlier responses to OjeySky) Battery manufacturers publish a DoD vs cycle life curve for their battery as well as C ratings - these numbers they publish are based on tests. I have said several times that Lithium chemistries are generally superior on cycle life and C rating but it does not mean that lead acid cannot take very large loads. AndroBlaze: 1 Like |

Egbon, we have access to each other back channel. You can put some cash behind these statements, supply 3 batteries - a premium grade lead acid, an average grade like Amaron Quanta and then any of the chinese el cheapos. I will provide an inverter with suitably adjustable LVD and load testing equipment. With two or more of us suitably invested we can perform a test, record the evidence and share with the house. Your point 2 - did you miss the part where I said an 100Ah battery derates to about 41Ah at 100a load at a Peukert coeff of 1.3? The Peukert effect you have thrown jabs at me on is a fact of life o and holds true whether you believe it or not. For your point 3 - can you state the lead acid batteries you have actually tested in practice? I have tested Trojan, US Battery, Rolls, Quanta, Deka, Genus, Luminous, Sinergy and a few others incl el cheapos with varied results. NiyiOmoIyunade: ojeysky: 2 Likes |

NiyiOmoIyunade: Really Bros you've confused me honestly... You started by claiming you can do 120a off a good 100AH LA, I told you it's not practically possible without the inverter lvd hitting within a short period. Then you responded with all sorts of tests you've done without any proof you've actually put 120A on a 100AH. I have used lead acid and still do and I know how voltage Sags even with just 50A load on quanta battery. Now you are going towards a different spin; testing of 3 lead acid batteries, spinning towards elchinco Vs premium LA which is not even what was discussed before. Bros just pick the one you consider to be best 100AH LA, put a 120A load on it and share result. I am willing to procure/provide the inverter for the test, you buy any lead acid battery of your choice. 7 Likes |

I've been reading about AC Spd installation after my inverter took a hit and have been buying the parts needed for said installation, but from what I'm seeing about the dos and donts, it's seems most spd solar installation I've seen are wrong. This especially is with respect to total length of live and earth wire not exceeding max 1 meter . Since most installers have to install the spd in a different box than the main distribution box, that 1 meter max is usually exceeded. Maybe that's why someone earlier complained his inverter took a hit despite having spd installation and why many might be "lucky" not to have had a lightening strike with such poor installation. |

If you are confused it is totally on you. For the record, below quote is how I started with key items bolded - I am still wondering what the ruckus from team Lithium is all about. If you want to do a lead acid test then bring batteries with known behaviour to the table hence I said bring one each premium quality, one each average quality amd any generic lead acid - you will see clearly that the performance and behaviour under load is not thesame across the grades. You use REPT and EVE cells for your LFP packs yes? Are they in any way better than GreatPower and all the various perceived lower grade cells? All LFP cells are not thesame, do not behave thesame and do not test or last thesame hence the market slaps grades on them and people chase the perceived best of the ranking scale as their budgets permit.

What SPDs are you buying? A lot of the el cheapo SPDs actually offer very little protection and with a lightning hit, you get only one chance. The 1st level and primary protection is the quality of your protective earthing, everything else depends on that, the job of the SPD is to limit the voltage rise the downstream equipment sees by rapidly shunting any faults to the earth. The 1 meter rule is to achieve best chance of protection in case of an induced surge by placing the SPD as close to the protected device as possible - 1 meter is a lot of space in an electrical enclosure and I see no trouble meeting it. If especially exposed or at risk, you can do tiered protection cascading several SPDs all the way from possible point of fault incidence to protected device. Overall I tell people to focus more on proper low resistance earthing and ensuring all energy generators and processors properly connected and not obsess too much over SPDs. See below a decent SPD I use all the time - note the length of the factory supplied cable. Namzy: 1 Like

TechGeek777: Look at it these way 12 batteries of (12v 200ah). You will series 4 of the batteries this now gives you 48v 200ah bank. When you series voltage goes up. Now do the same for the remaining batteries, you will have 3 different banks each 48v 200ah in value. Now you will parallel the 3 battery banks each (48v200ah) together . Now in parallel your capacity or ah of your battery increases so eventually end up with 48v 600ah single battery bank. |

NiyiOmoIyunade: I bought a tomzn spd. I can see you have a type 1 spd. Most of my worries with length is for type 2 spd as yhtas the most common ones I see in most installations. As the main distribution box is already filled with circuit breakers, they have to install the type 2 spd in a remote box from the main box thereby increasing its length pass the 1 meter mark |

This is a good one boss. Solar don epp me in many ways.

NiyiOmoIyunade: Bros we only have a point of disagreement which is your 120a on 100ah lead acid claim. It's very unnecessary and useless to even try to run a 120a on a 100AH leadacid. Saying that it will run less than an hour makes it look like it will serve for some minutes which is misleading, and that's what you don't agree to...that information is very misleading....however doing that with lithium will serve reasonable time. As to the test, you are the one that want to prove that LA will do some magic hence I will leave you to chose and provide your best LA while I provide the load inverter ![]() 5 Likes |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 9:12am On Aug 21, 2022 |
Perhaps you should upsize your cabling between the SPD and main panel to counter the extra length - it would have been easy to put the SPDs close by if you had planned for it from the get go. Do you have the MCOV and Clamp Voltage rating for the TOMZNs? This will give you an idea what level of protection they promise and you can then test using a high voltage generator (such as used for electric fences) whether the SPD is clamping any voltage at all. The Midnite SPDs are rated for Type 1 and 2 usage I think. Namzy: |

Okay. In the cold light of facts you are not as confused as you first averred. We can find a way to do this test you desire and see how many seconds or minutes the battery will hold up for - I will look out for an opportunity to lay hands on a good lead acid battery - interestingly I have not even seen a lead acid battery in person for at least 1 year now except in pictures and videos. Myself and customers are all LFP users but I started from lead acid and believe there are valid use cases for it - worst case lead acid is a very good place for a solar/RE newbie to start from and learn the ropes before graduating to the better battery chemistries you guys defend so vigorously. Again my point to Saint2Ace is that no residential user loads their battery to deplete it within 1 hour so the example given could mislead a non technical person and therefore be wary of using such examples. ojeysky: |

Very good boss - for this one you posted the MCOV aka Uc is 275v - means the SPD will start to operate if it sees line voltage above 275v. The promised clamp voltage aka Up is 1,800v at Ln 30kA of surge/fault current - this means your protected equipment or loads will witness 1,800v if a surge of up to 30kA passes into the line. The question is can your equipment or loads withstand 1,800v pulse and not go kaput? Only UL listed or similar rated equipment can withstand up to 2,500v. I am fairly sure most el cheapos do not have a UL or similar rating In balance, the fault presented to your equipment may never reach up to 30kA (you may be lucky) but there is no way to know. Lastly, can the TOMZN SPD even deliver on these promises written on the label? The only way to know is to test. Namzy:

ojeysky: TBF Ojeysky, I am not accusing you directly of spitting at LA....but I do have to say the tune has changed when it comes to newbies jumping instantly on the Lithium train and I think that is worrying. I just want us to understand that their is a necessary learning curve to this RE lifestyle, and LA is a very important part of the picture. I do not think your story on LFP would have been so successful if you had not learnt first with the patient and forgiving teacher LA is. Lets not believe we have star pupils here, people will make mistakes and its best they make those mistakes with LA because it is the better chemistry to learn with. 1 Like |

I strongly agree with you on this. Our dear Egbon OjeySky is leaving out his not too positive experiences with the first generation of LFPs we got which had very weak threads on the terminals that stripped no matter how careful one was, how we sought threaded bolts to solve the issues and ultimately went for welded studs as we purchased subseqent batches, issues with poor contact and busbars heating up and need to retorque connections from time to time, the search for a good reliable BMS, dashboard integration, to compress cells or not to compress them and so many others. Doubtless his prior experience with lead acid helped to build his confidence, shape his expectations and arm him with the skills to tackle the obstacles using LFP but now he wants a newbie to go straight into all that? A newbie that may not even understand how cells stack up in series or what cable gauges to use for different parts of the LFP battery pack and balance connections not to talk of wiring up a BMS or the required settings. If he comes and says a newbie should just purchase a ready made LFP pack; which are the affordable ones that are true to stated capacity and possibly not using substandard or second life cells? The ready made packs most folks are putting up here for sale both mass market and DIY builds still need a lot of work and a few generations of improvement before they are truly ready. AndroBlaze: |

So then balance the narrative constantly as some others try to do. As a technical person nearly all your good answers should be qualified with 'caveats' and 'it depends' and 'if this assumptions hold then so and so happens otherwise'... That is the duty of care we owe when putting up info publicly that others may rely on - we need to give them a fair and balanced comparison so that they can make informed choices. ojeysky: 1 Like |

Re: Solar Energy, A Complement To FTA by AndroBlaze: 11:09am On Aug 21, 2022 |
NiyiOmoIyunade: Well if my years of experience of living with LA in the real world is not testing them, I wonder what is. Anyway, as the goal here is for all of us to learn the easy way (through experience prefeably than experiments that are costly)... I am sharing another video with more "English" and more expensive LA batteries used apparently....but its still the same findings which is consistent with what we LA users live with and know. Not as easy and simple to follow as the other video, but still points to the same thing, which if I can use Ojesky's word,"LA batteries will not perform magic" no matter how expensive. So I still stand by the claim earlier, "you cannot get 120A from a 100AH LA for 20 mins or anything close to that in real life use". Obviously we await your test or any other test debunking this. https://www.youtube.com/watch?v=iy3hga_P5YY&feature=youtu.be 3 Likes |
