earthrealm: I can attest to the port congestion (which I believe is deliberately done to make importers desperate enough to allow themselves be extorted) when a container with my items on it stayed from August till November! Then they made the importer pay extra ₦2m as demurrage. 3 Likes |

earthrealm:Me I use fuse for each cell with My DIY BMS to balance the cell. Any cell that fails the fuse will isolate it from others but will reduce the capacity of that cells 3 Likes 1 Share |

Dishtech: So a 12v 200ah bank for instance may have upto 150 cells?. Correct me pls. So u wud have 150 separate fuses, from pictures i have seen, how easy wud it be to separate the bad cells from the matrix and replace them with good cells?. You spot weld or just solder?. Can i see a pic of your bms & connections |
Re: Solar Energy, A Complement To FTA by Dishtech(m): 8:30am On Nov 19, 2021 |
earthrealm:. 200Ah will be about 230 if 3series configurations cells since the cell is ICR18650-26 (2.6Ah) but I configure 4s12p for my laptop power bank and 7s48p about 124Ah for my inverter. I use soldering iron because I use fuse wire. I didn’t snap when I was configuring but that is the 4s12p and the BMS originally meant for 3s but i later added one to make it 4s. By the grace of God my friend wants me to configure the same 7s48p for him when I do that I will send you the whole setup |

bigrovar: Thank you for the reply. How do I make sure that my battery depth of discharge is within the 15%-20%. |

mctfopt:The charge controller (and my solar setup is in my signature) is victron 100/150. My current arraey is 335w x 9 arranged in a 3 x 3 x 3. The end PMV is about 90v. The controller would be able to sustain a 5kw solar array (just about) |

Keemie:Have a handle on your load. This is the key to a successful off grid life. Lot of people put too much focus on the solar, inveter, battery forgetting that the first and most important component is your load. You need to do proper energy audit because the load determines how your system should be designed vis a vis your financial budget. It is what would make you understand what is capable within a budget outline. I don't have to do anything about my setup. The system runs itself because the load is fixed. I know how much power I draw everyday and how much my solar array is. My setup can generate over 2.7kw or power from the sun, out of which the house load (during the day) ranges between 350-500w. Charging the battery to full (float) requires about 1000w (for about 2 hours it takes the battery to be full from a 80% state of charge) This all means that I have lots of redundant power to play with. Thus inverter is setup the following way Switch to solar during the day (when the battery is higher than 26v) Switch to Nepa (if available) when the battery voltage drops to 24.5v (Usually at night or during cloudy stormy weather) and if Nepa is not available switch to battery. Being on premium power and being guaranteed 20 hours of power everyday means that my battery is rarely used except for about an hour when the inverter uses battery until the battery voltage drops to 24.5 then it switches to grid. 24.5 for floaded tubular battery is at about 80-90% soc. 4 Likes |

bigrovar: Thank you so much for your reply. Do you have any experience with luminous tubular battery. Is it good. |
Re: Solar Energy, A Complement To FTA by mctfopt: 3:49pm On Nov 19, 2021 |
bigrovar: Oh, that's awesome. |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 4:37pm On Nov 19, 2021 |
Keemie:They are pretty much the same. Luminous is one of the biggest battery manufacturer in India. The things to watch for are capacity inflation which is a thing in Nigeria. I had an India battery OEM confirm this to me in private how marketers pressure them to mislabel capacity. 180AH becomes 220AH. Second thing to what for is electrolyte. The part many don't say enough about tubular battery is pure quality electrolyte mix they have once they get to Nigeria. Most are shipped dry and then the electrolyte is mixed here in Nigeria. Unfortunately care is not taken to ensure the right gravity is achieved or that distilled water is used. What this result to is a battery with either poor nominal voltage (and serious voltage sag issues) Or one with too much acidity that the battery dies within a short period. Luminous is sold by Simba and they are a big brand so probably they do right thing. I have no insight. 3 Likes |

Good day house, what is the average cost in terms of service fee for installation of solar panels, inverter and batteries? Thanks |
Re: Solar Energy, A Complement To FTA by luvlyoracle(m): 12:53pm On Nov 20, 2021 |
Paulfroshman:It all depends on whom is installing,what he is installing,how hungry or boxed up he is..lots of factors. No constant price at all. |
