Good afternoon house. I am in need of a decent setup for a freelancer. Budget is 200k. Kindly help with a list of things to get and prices. |

Daboomb:This snapshot is from a lithium ion battery pack of my battery builder (Ola Emmanuel). He has three battery banks put together. First pack is 220AH Second pack is 240AH Third pack is 260 AH. His batteries are in 14S configuration. His night usage alone is between 24kw & 25kw on a daily basis. Below is his latest battery history. 1 Like

Kindly provide pictures of your spec sheet if a comparison is done between this and your Charge controller, it will need 18V - Vmp from your panels to drive itself or charge battery, - "potential difference" Having 12V from your battery may not provide much power as expected while feeding it from panels directly will give you the needed results A 450W - 600W I.e. 150W x 4 pcs will give you needed power at early morning, late evening and cloudy days, than when just using 150W x 2 Polaris1: |
Re: Solar Energy, A Complement To FTA by Polaris1: 7:08pm On Nov 12, 2021 |
olopan: Thank you. I haven't bought the pump, only seeking experiences and advise. I intend using 12v 200w x 2. I don't need early or late evening functions because I have a big water storage tank for use during non optimal hours. Will such pump run for 6 continuous hours 5days a week? Does the fluctuating voltage that solar panels provide affects it's efficiency? Thanks again.

Re: Solar Energy, A Complement To FTA by olopan(m): 9:43pm On Nov 12, 2021 |
Running it continuously for six hours is not advised, two-three hours at a go is Okay, especially for longevity and to do its worth or performance With more power from the solar panel, the fluctuation of voltage will not matter, as your load is covered Polaris1: 1 Like |

obimind: Oga Obi, what is "second life" or do you mean to say "Second-hand" lithium iron battery? I have never heard of that term before. Where and when did it use its "first Life"? Or do you mean "Grade B" battery? |
Re: Solar Energy, A Complement To FTA by ewizard1: 12:55pm On Nov 13, 2021 |
Daboomb:That's the term for it. It used its first life in a previous product before it was extracted and used for a Solar energy application. Like the "Second Phase of Life" |

Opistorincos:I spend a lot of time online and needed to power lights, laptop, fan and phone. Here's what I bought: 12v 150w x 2 mono panels 23x2 = 46k Souer 1kva pure sw inverter (solar charging only) = 40k 40amps pwm charge controller = 15k Six months old 100ah Mercury battery bought from a neighbor that was upgrading = 25k Cables, clips and mounting = 10k That should be 136k I didn't add any switch, fuse or breaker. I use 15wx2 light bulbs. My windows 7 laptop is old school not a power guzzler. I bought a rechargeable DC only fan (13w) and connected it directly to battery terminals =18k I added a dual power 12v/220v (30w) lg 32" television and connected it to the same battery terminals = 55k I sometimes use a 500w rice cooker = 6k My bedside fridge is 70w (220v), when there is good sun, I switch it on for 1hour =30k My battery will float charge (14.2) around 10a.m on normal days, in the evening around 5p.m it's 12.7v. After powering only the fan overnight, it will read 12.5v. I schedule laptop work to be in the daytime, I use the phone at night I can use the lights and fan 24/7 I can watch TV non stop while sun is up Those prices were for February, 2021 I have been happy since. 5 Likes |

You have managed your setup quite very well ![]() BTW your battery just enters absorption at said time and on days where you didn't use so much power from your battery, you should notice the battery resting at around 13.7V or 13.x depending on your charge controllers setting Polaris1: 1 Like |

obimind:This is very good! Reliable local assembly is what we've been looking forward to for so long. Kaduna. Jos. Now Lokoja. I have client whom used Luminous VRLA for over 4 years with routine 50% or higher DoD. Prompt recharge though. Batteries are still in service but for 20% DoD over the past 2 years. That'll be 6 years altogether by December. Of course that's an aberration. Even I wouldn't use it as a benchmark. My own initial Trojan bank made 4 years easy but by being babysat more than a human baby. I have LiFePO4 from 2010 which are still alive as we speak. Occasional returned to storage then intensive use again but they've been in active use no fewer than 5 years. I'm currently using 450AH 48V nominal of BYD LiFePO4. The performance is at great. The minimal voltage sag even under heavy discharge (I cannot exceed 100A discharge due to inverter limitations) is no less impressive. And even as GeorgeD1 has touted, it's the path to the future. Until it is usurped. I still maintain my indispensable VRLA bank for abuse and stuff I wouldn't dare with the LiFePO4 for fear of having a cardiac arrest before dawn. 4 Likes |

ojeysky:Peak discharge of about 130A at 52.7V translates to about 6.8kW. Is this your 8kW Deye at work? |

Needed: - a minimum of 5kVA hybrid PSW inverter with dual input of at least 350V per string. New or used. - used 5kVA to 10kVA Victron inverters Kindly reach me on O8O239O23O5 (calls/WhatsApp). Or drop your details here. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:43pm On Nov 14, 2021 |
Saipro: Yes it is though it will be at 48v for actual load. The 52.7v you see on the image is the battery voltage when the screenshot was taken(inverter was discharging at 26+A at that time) |

ewizard1: Good one from you there. So, without the 'deception' of semantics, these "Second Life" Lithium batteries are USED, Second-Hand Batteries. Full Stop. Now, if that is the case, my questions are: How do you guarantee or confirm the amount of Cycles left inside it, bearing in mind that the only reason we go for LiPo4 Cell batteries are because of its reputed 5000+ Cycles? How do you TEST, that a Buyer is not being given a Used, second-life Cells, for the price of a New Ones, if a buyer requires New, grade A battery Cells. It could well be that such Cells in a battery are closer to their "End of Life", than a "Second Life", without the new owner being aware, yet having paid top money for them! I know you are a seller and l should not be asking you a question like that but l have the feeling you are a honest person and will always speak the truth. Other Experienced/Expert/DIY RE proponents should please weigh-in on my question.

Re: Solar Energy, A Complement To FTA by ojeysky(m): 11:19am On Nov 15, 2021 |
Daboomb: Cycle life is one thing, the performance one of the major other reason and remember that typical lifepo4 will still have 80% capacity after it's first cycle round. I have no comment on that particular second Life cells as it all depends on the usage of the initial user.... Some may still be in their initial cycle round sold as used. I have sold my used lifepo4 battery bank before with just about 200 to 300 cycles. |
