Juror: Not as much as it does tubular or flooded acid batteries. AGM has a very low self discharge I think about 5% a month, can't remember the actual number. You can look it up. |

FEGEITOK: This is close to what I get from my Canadian solar. Even with not being optimimally oriented (they face south east at about 124 degrees of azimuth as against 180 degress) and at about 21 degrees tilt (as against 5 degrees) My panel constantly do north of 80% of their name plate, that is about 4.5kw of 5.4kw PMAX. Note that I am paring them with a 100A solar charge controller which means generation is clipped at 100A when in fact the panels are designed to produced 112.6A. so in a way should be getting more from the panel if I were using a bigger solar charger or if I were to divide them between 2 controllers. For the OP I suggest get can squeeze more from the panel if he can put them on rails and have them tilted a bit to achieve close to 18 degrees tilt. This would require the work of an experience installer. They would need to fabricate an L foot for him. I did same with my system 1 Like

Mini review of Lifepo4 batteries from Selina of Shenzhen Deriy https://deriy.en.alibaba.com/?spm=a2756.trade-list-buyer.0.0.446c76e9yMKAWz&tracelog=from_orderlist_company . Order Process The order for 16 x Eve LF280K cells was placed sometimes December 2022, they were shipped out sometimes in January and I got delivery notification in march. I had no issue getting the batteries from the shipper. I ordered extra items like non polarized breakers, extra busbars and nuts, and a battery tester the EBC A40l Smart Battery tester. All items came delivered with the battery. Physical Condition of the batteries Battery came in pristine conditions, they looked brand new and no physical damage can be seen. The packages was well done. I settled for the dual terminal batteries, the only issues I had with this was the terminals were wielded in a way that makes it impossible to line the batteries close together in a build without shorting them. This was not a big deal for me though. Testing On getting the batteries, I carried out extensive capacity test to ensure they batteries gave the rated labeled capacity. For this I used the EBC A40L smart tester. I connected the tester to the battery and connected my laptop to the tester, The tester application allows you to set charge and discharge parameter and you can see a graph of the voltage curve of the battery in real time as it charges. I set the tester to discharge the battery to 2.6v (voltage of a fully discharged lifepo4 cell) and then immediately charge each cell to 3.65v, it would then cut of charging once the charge amps is at 7A. I logged the capacity of the battery once it got to 3.65v (The voltage of a fully charged Lifep04 cell) in all every battery cell was at 280+Ah (some at 284, the least was 282ah) once the voltage reached 3.65v, this means that the battery were the corrected labelled capacity. Building into a bank I assembled the batteries into a bank 16S to ad to an existing 16S 280AH Eve battery bank. So so good. Still early days but the cells are doing well. Each bank is attached to its own JK BMS In all, I am a happy customer, Selina was very helpful especially her employee Colin, both of them speak good english and they were very communicative during the whole process. 12 Likes

bigrovar: For my own micro review of Lifepo4 batteries from Selina of Shenzhen Deriy, I have 2 different contrasting experiences. 1. Very good experience: Last year 2022 April ending I ordered and paid for 16 pieces of EVE LF280K batteries from Shenzhen Deriy. Shenzen Deriy handled the shipping and the batteries were delivered in about 3 months (July 2022), I picked them immediately they arrived, they arrived in excellent condition. I completed the build and installed them, I've been using them since then till now. 2. Terrible experience: Immediately after receiving my first order, I placed an order for 32 pieces of LF280K in August 2022. Paid for the batteries and shipping with Shenzen Deriy handling the shipping. I did not receive these batteries untill about a week ago April 2023 ( after 8 months). Before i could pick up the batteries I had to pay the shipping company an extra N90,000 even though I've paid Shenzen Deriy full shipping fees. Till date both Shenzen and the shipping company could not explain the 8months delay, all they say is that there is a problem with the container, at some point both even stopped responding to calls and messages. I introduced 2 people to Shenzen Deiry, they ordered their cells end of November 2022 and picked up in February 2023 while I was still waiting for my cells. Some other people ordered in January 2023 and picked up their cells before I picked up mine. I don't know if my second experience is a one-off or happens on the regular but the experience has thought me to handle my own shipping when next I order. I thought I should share so that other can see the 2 ways it can go. 8 Likes |

Thanks so much boss i so much appreciate. Okay i will go with 5.5kw inverter X 2, then 15kwh battery bank X 3. Then 10.8kwp arrays(540w X 20). I don't know whether it is okay. Another thing, this felicity 15kwh is it complete 15kwh or their normal over hype of their products. durodee: |

Hello house, I met @justcallmenuel on this platform and I have made purchases from him numerous times but it's high time I stopped dealing with him. He lacks understanding and does things his own way without consideration for how the customer feels. I need to replace a battery for a client, out of 4 quanta batteries, 1 gave up and it's giving the client (a cancer hospital) so much worries, client wants the battery bought and replaced today in other to save his patients. I chatted Nuel up last night and asked if he could make it possible which he guaranteed that I will get it in Abeokuta by 1pm at worst, i told him 12noon will be better and we agreed. I reached out to my ibadan vendor and he confirmed he has in stock too, but just because of the relationship with Nuel, i decided to buy from him. Only for him to tell me this morning that the park that sends to Abeokuta there no longer exists, and if they have to take to iyana ipaja, i have to pay #10,000 for the delivery to the park, excluding what the driver will still charge to deliver to Abeokuta, just a single 200ah quanta battery. I told him I'll rather have a refund if you can't keep your end of the bargaining or you do something about the delivery cost, this mindless Nuel told me he can't refund, he bought it from someone too and went ahead and send it via the haulage that won't deliver until tomorrow, this is after picking up from my ibadan vendor. My fault was to think I'm keeping a relationship with him by coming back to buy, but right now I'm blocking him off totally. Just know that before you start threading this path, @kiekie1 was once relevant like you in this forum. No peace for you @justcallmenuel 9 Likes |

viperVIP:I knew you would bring it on here. I explained to you that the park no longer stays over there because of the road they are constructing at iyanoba, so they had to move to iyana paja ( according to my aboki that took the battery there), gave you price for the delivery which you said you can’t afford. Will I be the one to pay delivery fee for you all the time? How many times have you sent Growatt inverter to me from Abeokuta to fix it for you, which you and I know that their office is in Lekki. How much does dispatch charges to Lekki? It’s 12k. But I do collect 8k to and fro from you and add the balance cos you bought the inverters from me. Did I tell you all that? NO. The last inverter you sent to me for repair, you told me to help you wrap it and send back to Abeokuta for you, that you’ll send me money for carton, which I didn’t see carton to wrap it and I bought wrapping nylon of 4k and wrapped it so it doesn’t get scratched, You wanted to send me the money but I told you to forget about it. So many things I’ve done for you as a customer, but I don’t tell you. But because of what happened this morning, you ran here to type, just to spoil my name. Chief, dey check well o 3 Likes |

viperVIP: From the few times have transacted with justcallmenuel. I can say boldly the experience has been good. And I can safely recommend him. Based on your side of the story, I think it's an issue of understanding, since Abeokuta park is no longer available, i think he is handicap. The two of you are egbon, and I believe you can both find away around it. Talk to him I believe you can find a mutual ground for the delivery price. 2 Likes |

Will I be the one to pay delivery fee for you all the time? How many times have you paid delivery for me, cos you sounded as if you're doing free bonanza on my orders? I only sent growatt to you twice young man and I never said I wouldn't be responsible for the logistics, you said the first one you have a product going that way, so you'll add up. Second one, you said i'll be responsible and i ask for the price, you said it and I paid, If you did pay 12k, you will say it, i know you.

Re: Solar Energy, A Complement To FTA by Drgreatone: 3:03pm On Apr 28, 2023 |
House gurus pls help... My afripower 1kv inverter stopped charging wit nepa/phcn for a few weeks now. Suspected it was the fuse in the input socket plug that was faulty but didn't hurrily replace as I av a suoer external charger which i use to charge my battery. The suoer charger fan however failed some days back and it gets extremely hot, i had to open it up and only use it when i get home so i can use an external fan while its working. Fixed the inverter socket fuse yesterday and when i plugged it to charge wit nepa, inverter went off for a few seconds, had to switch of the inverter and change over from inverter to mains and it started charging. However ths morning when phcn went off, I changed over to the inverter while it was plugged to the mains, there was a backflow wit sparks in the inverter and the inverter died wit the screen blank and no output. However 10mins after, it came on again and was working. Tried plugging another appliance to the same charging spot which didnt come on and nothing happened with the inverter. Is it possible the new fuse caused a back feed? Can anyone help me wit suoer internal fan in Abeokuta or waybill it or what alternative do i have as the rechargeable fan i use doesnt come on automatically so its only when i am home i am able to use it? |

Re: Solar Energy, A Complement To FTA by olopan(m): 11:57pm On Apr 28, 2023 |
It depends on what your preferences is 1. if you own a prepaid meter with a stable power predictable grid supply then you might want to maximize you solar production to squeeze more from your solar panels. so any deficient during the day you refill at peak time of grid supply 2. if without prepaid then maximize grid usage as this will ensure that battery is in constant close to being full daily without worry of downtime as the sun is there to backup. osayuwamwen: 1 Like |
