Ah boss you just broke whatever is left of my heart o! I sell various RE products but that is hardly the focus of my efforts here. Perhaps I may make one sales related remark once every 50 posts or more. The goal is to learn and share knowledge. There is a lot of misunderstanding about why a Pylon commands a higher price tag and I wanted to provide perspective on the features that justify that price point. The first thing I said quoting the test results is that there was even a battery with slightly better performance than Pylontech - that would not serve the purpose of a sales pitch. adrusa: 2 Likes |

See my first post on test methodology please. Paraphrasing ...Each battery pack is charged over several hours (mimicking daytime charging from the PV), followed by a short rest period, then discharged over a few hours (mimicking the late afternoon, early evening period) to between 90% to 95% DoD as allowed by the BMS, followed by another short rest period. In total, there are three charge/discharge cycles per day. Also temperatures were varied to mimic summer, winter e.t.c as the batteries were cycled. The above can only be called "aggressive use" I can't recall but the discharge window was about 3 to 4 hours so a 0.3C rate - at 1,940 cycles the battery had done 5.3 years of this treatment and was still trending 2% above the promised capacity retention. Please recall that the manufacturer said 80% capacity left after 6,000 cycles at 80% DoD so in this testing DoD was above 90% and the battery was so abused 3 times a day and effectively did not complain in any way and had done more than 5 years equivalent of use under these harsh conditions and still kept 82% capacity.

truthbetold22: thanks for your analysis bro. you made a lot of valid points but missed out on a few. my zeniths didn't last that long only because i had an oversized bank and solar array. it was more a combination of factors too numerous to enumerate here. go down memory lane and we have heard sorry tales from peeps and even companies who installed large battery banks and had them fail woefully within the first or second year. my reference to people getting their fingers burnt resonates both with lead acid and lithium. i will encourage you to read up that website that earthrealm posted a few pages back and you will understand where i'm coming from. be it lead acid, lithium or any other battery chemistry, if you jump into it ill-informed you will certainly pay a huge price not only in terms of loss of investment but also at risk to your own personal safety. i repeat that no one battery chemistry can claim to be better than the other. each has its own place. if i'm using lead acid and it is delivering exactly the performance i expect, why change a winning team? on the other hand, if for any reason lead fails me tomorrow, why stick with something that's not working? the goal here is energy freedom and as long as what you're using is setting you on the path to achieving that aim, i would say go for it. it's as simple as that. 2 Likes |

adrusa: bro, i don't know where you got that 'complex' thing from but i certainly don't have one. yes i invested heavily on lead acid but that was because i was crazily impressed with what my previous bank gave me - and that in spite of all the hues and cries going on here against lead. so my thought was, if i could get this kind of good performance from a supposedly no-name battery brand, what if i get something more reputable as a replacement? and with that consideration, the sonnenschein battery deal was a no-brainer to me. anybody in my shoes would do exactly the same. it was a deal too good to resist. would i have jumped at the offer the way i did if i had been having a hard time with my zeniths? i think not. were they necessarily that expensive despite being a renowned brand? of course not. even though for a similar amount i could have splashed out on a lesser sized lithium bank, my overriding argument goes beyond just price. on a cost/ah basis, lead acid is clearly ahead until such a time when lithium becomes mainstream but on an energy efficiency basis, vis charge and discharge cycles, lithium rules. still it doesn't make either one superior to the other. each battery chemistry has its place. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 5:23pm On Oct 25, 2020 |
all, over the past two weeks, we have had a lot of interesting argument both for and against lead acid and lithium. and like that flier earthrealm posted a few pages back, https://www.nairaland.com/390522/solar-energy-complement-fta/878#95271112 the aim of an argument or discussion is not victory at all cost but to bring out facts and enrich our knowledge. we all win when we learn from each other. and on that note i like to commend all who have taken part in this discourse so far. it may have seemed heated at a point but that cannot be avoided. it is what happens when intellectuals rub minds together. looking back, it's amazing how a simple, innocent question from babniyen, https://www.nairaland.com/390522/solar-energy-complement-fta/871#94990932 could have triggered a wide ranging discourse on the superiority or otherwise of one battery chemistry over the other. have we seen the end of the battery 'wars'? not by any stretch of the imagination. today it is lead vs lithium. tomorrow might be lithium vs some other emerging battery chemistry and the list goes on. let's keep the conversation healthy and together we will all achieve victory over darkness. break the myth! dispel the belief! 4 Likes |

RE ITP Cranberra Battery Test Results I inferred from the reports that the PylonTechs were discharged to ~92-95% DoD over a 3 hour period 3 times daily - so a C3 discharge rate 3X daily. This same regimen was applied to other batteries and sometimes reduced to C5 for those other batteries if the battery started to become unstable.... Pylontech US2000 - Based on the linear regression between estimated SOH and cycles completed (Figure 13), the Pylontech US2000 is on track for 60% SOH at ~4,340 cycles. However, a linear extrapolation may not be appropriate as while a linear regression appears to provide good fit to some of the capacity test data collected thus far, extrapolating linearly into the future may not be appropriate. Sony Fortelion - Based on a linear regression between estimated SOH and cycles completed (Figure 12), the Sony Fortelion pack is on track for 60% SOH at ~6,400 cycles. As above, however, a linear extrapolation may not be appropriate. The Sony Fortelion appeared to best retain capacity and ultra long cycle life but was less consistent in taking a charge and delivering the full energy stored [90% to 95%] 3X daily as compared to Pylontech. This can be inferred from studying the capacity fade charts provided. The Tesla Powerwall 2 cycling regime is implemented by Tesla, based on requests from ITP. This requires intermittent communication with Tesla as their implemented schedules periodically expire. Based on the linear regression between estimated SOH and cycles completed (Figure 13), the Tesla Powerwall 2 is on track for 60% SOH at ~3,100 cycles. As above, however, a linear extrapolation may not be appropriate. LG Chem RESU HV - Based on the linear regression between estimated SOH and cycles completed (Figure 13), the LG Chem RESU HV is on track for 60% SOH at ~3,100 cycles. As above, however, a linear extrapolation may not be appropriate. GNB Lithium Based on a linear regression between estimated SOH and cycles completed (Figure 13), the GNB Lithium is on track for 60% SOH at ~1,300 cycles. As above, however, the data suggests some non-linearity which may invalidate this extrapolation. When I look at all these results - 80% DoD is still the best place to be for stable and reliable long term operation of a Lithium battery pack except perhaps the LTO Tech of which I have no experience. |

My own effect of DoD results - at 88% all 20 Pylontech bricks are in perfect sync as regards their capacity - below 40%, you begin to see deviations - BMSes all talk to each other and aggregate total pack capacity, setting the weakest brick as an average for all such that no cell/brick is over-discharged - it may mean that you install a 1000Ah bank but can only use 950Ah because one brick has lower capacity than the others You basically want to look at the column called 'Coulomb' which is the SoC % At 88% SoC Pack 1 pylon_debug> pwr pwr @ Power Volt Curr Tempr Tlow Thigh Vlow Vhigh Base.St Volt.St Curr.St Temp.St Coulomb Time B.V.St B.T.St 1 49892 -1082 30000 27000 27000 3325 3327 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 2 49898 -1074 29000 26000 27000 3326 3327 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 3 49889 -1054 30000 27000 27000 3324 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 4 49884 -1093 30000 27000 28000 3323 3327 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 5 49875 -1107 30000 27000 28000 3323 3326 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 6 49896 -1082 30000 27000 28000 3324 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 7 49883 -1030 30000 27000 28000 3324 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal 8 49892 -1034 30000 27000 28000 3325 3327 Dischg Normal Normal Normal 88% 2020-10-26 01:01:34 Normal Normal Command completed successfully $$ Pack 2 pylon_debug> pwr pwr @ Power Volt Curr Tempr Tlow Thigh Vlow Vhigh Base.St Volt.St Curr.St Temp.St Coulomb Time B.V.St B.T.St 1 49889 -1050 29000 26000 26000 3324 3327 Dischg Normal Normal Normal 88% 2020-10-26 01:02:49 Normal Normal 2 49905 -1100 29000 26000 26000 3326 3329 Dischg Normal Normal Normal 88% 2020-10-26 01:02:48 Normal Normal 3 49891 -1090 29000 26000 26000 3324 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:02:49 Normal Normal 4 49920 -1083 29000 26000 27000 3327 3329 Dischg Normal Normal Normal 88% 2020-10-26 01:02:48 Normal Normal 5 49902 -1235 29000 27000 27000 3325 3329 Dischg Normal Normal Normal 88% 2020-10-26 01:02:49 Normal Normal 6 49918 -1168 29000 27000 27000 3326 3329 Dischg Normal Normal Normal 88% 2020-10-26 01:02:49 Normal Normal 7 49891 -1092 30000 27000 27000 3325 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:02:49 Normal Normal 8 49902 -1086 29000 27000 27000 3325 3328 Dischg Normal Normal Normal 88% 2020-10-26 01:02:48 Normal Normal Command completed successfully Pack 3 pylon_debug> pwr pwr @ Power Volt Curr Tempr Tlow Thigh Vlow Vhigh Base.St Volt.St Curr.St Temp.St Coulomb Time B.V.St B.T.St 1 49936 -1591 31000 29000 29000 3327 3331 Dischg Normal Normal Normal 88% 2020-10-26 01:01:40 Normal Normal 2 49942 -1843 33000 30000 31000 3328 3331 Dischg Normal Normal Normal 88% 2020-10-26 01:01:39 Normal Normal 3 49945 -1483 32000 30000 31000 3328 3332 Dischg Normal Normal Normal 88% 2020-10-26 01:01:39 Normal Normal 4 49952 -1536 32000 30000 31000 3328 3331 Dischg Normal Normal Normal 88% 2020-10-26 01:01:40 Normal Normal 5 -

GeorgeD1: I still maintain to differ in this your assertion. But of course that's my opinion as well as you having yours, but opinions do not really disprove facts, do they? The facts are as clear as day. GeorgeD1: Your statements points out the fact that one is clearly superior to the other. I won't point out which. There is no way the old beats the new. There is a reason it is called new and a made a replacement. Of course if it wouldn't be widely accepted and if it isn't good enough for people, it is only a matter of time before it will be thrown into the backseat in favour of Lead Acid chemistry. Case in point is 3d television, though a new concept but because of the encumbrances with using it, the rave died down as quick as it came and people went back to their 2d offerings while development shifted to increasing Fidelity. Ditto blue ray discs. But I clearly believe one thing, all R & D into storage chemistries in recent times is based mostly on polymers of Lithium with other elements to achieve various desirable characteristics. Graphene is another element that seems to come close to lithium in recent R & D efforts but none is majoring on lead acid. That is to tell you that that chemistry has peaked already and can only be replaced. The only great thing about LA though is that it is fully recyclable in sharp contrast to lithium but that is not even enough reason for researchers to keep looking into improving it; it simply does not have extra to offer and tinkering with it beyond what has been done in the case of Lead-Carbon coating of electrodes isn't likely to offer more. Lithium is not a new concept, it's been around for decades but R & D into it has brought this much improvement. It will also reach its own zenith where it will likely be replaced with better offerings as tech improves. 1 Like |

We seem to always misunderstand each other or get on opposite sides of the facts. This is from the testing procedure page; I can attach a screenshot if required; ... to investigate this capacity fade, the lithium-ion batteries are being discharged to a state of charge (SOC) between 5% and 10% (depending on the allowable limits of the BMS), while the lead-acid batteries are being discharged to a 50% SOC (i.e. 50% of the rated capacity used). The advanced lead battery is being be cycled between 30% and 80% SOC. These operating ranges are in line with manufacturers’ recommendations for each technology. Please quote or reference where you see/saw 85% DoD? ojeysky: |

However, the test reports document the summary results over 6 months on average and clearly mention SoC of 5% to 10% as the discharge range. From about November 2017 reporting the test range widened to 5% to 20% SoC. Perhaps it will be possible to clarify the specific usage regime each battery has faced over time. ojeysky: |

No one can know what the projected results will be until end of testing or failures begin to happen. I really do not want to be screaming Pylon this and Pylon that - the discussion started as Lead Acid vs Lithium and then moved to 'perceived premium' on some ready to use LFP vs generic or DIY assemblies. My goal was to put out information and let readers know/see reasons why one would choose a more expensive battery - to help justify the price premium as it were. Anyhow one swings his projections, one cannot gainsay the fact that this was in effect a relative test of several popular Lithium batteries and a few other types - the Sony Fortelion and Pylontech bricks have clearly held their own and outperformed other batteries in their class under exacting conditions. In my own offgrid home_office, I am depending entirely on 20 units of the Pylon US2000 for all power needs so they must serve me for 10 years +. My own conclusion which I reached based on nearly a 100 modules installed and to which I have access to monitor their performance data is to stay within 80% DoD - the decay and imbalances that would trigger failures usually show up as you discharge to 90% and beyond [somewhere up above I showed my own pack balance data at 88% and 33% SoC] - I even got a large costumer to grudgingly agree for us to restrict his site to 80% DoD - he is a very exacting man who wanted to flog the battery to death and squeeze out every last penny of benefit for his commercial application. This is what the ITP (tester) had to say about their test methodology; """The accelerated cycling methodology was designed to enable analysis of battery performance over a shorter timescale than would be possible in a typical installation. However, this did result in the batteries being worked harder (although still within manufacturer specifications) than would normally be the case in solar-storage applications. This led to de-rating and failures that might not normally arise, particularly related to heat management.""" I suppose the real question is, if the top range or organized market for Lithium products are putting out batteries and making promises on their spec sheets which are not holding up to real life (ab)use, what would happen to the more generic batteries and DIY assemblies who have less standardization, quality control and engineering competence behind them if (ab)used under similar conditions ![]() ojeysky: |
