Re: Solar Energy, A Complement To FTA by bbally: 5:40pm On Mar 26, 2022 |
please, like how many watt will a 1hp INVERTER AIR-CON draw from an inverter system and will it have any dangerous effect if the system is 12volts? |

mctfopt: if I can get BMS with Bluetooth I would buy. I couldn't find one. I've packed it all together but below is the battery I used, made in India. sold 1k per piece, bulk purchase might be around 850 plus. Drove over 15km to and fro today with a passenger total weight over 150kg and it's just 1 bar from 3 I used. I don't know if you will find this battery in Alaba, the person I bought it from imported it personally. if I find the receipt will share his number. 3 Likes

Hi pros. Please I need your inputs. Trying to perfect a system the has the following demands. Total load is BTW 19-25kW From 7am to 10pm daily. Looking at Oversizing panels so that the panels handle sunrise to sunset and the batteries handle from sunset to 10pm. Earthrealm, niyiolu....mctfopt, GeorgD...etal thanks |

Moneyboyz: That's cool, your cell looks like some 60 pieces I bought sometime last year @ $1.2 each from China. The pricing of yours is not bad. BMS with BT feature full AliExpress. Aesthetics is never most of our priority in this part of the country. We just want it to work Cheers on your huge bank 2 Likes

solasola: This type of load is best designed using both grid tie- generator combo with some sensitive load directly powered by inverter. For instance, if you can get a 50kw SMA grid tie inverter to handle the heavy load, other sensitive loads can conveniently be handled by a 10kw Victron hybrid inverter running off battery. Make other chairmen put mouth for the talk Edit: I didn't see the 10pm..thought it was strictly for handling day only (7am to 6pm) affair. |

Thanks baba, might look at the 7am- 6pm of course mctfopt: |

Thunderbolt: I will go for lithium, it's 100k more expensive but you will have changed the luminous twice while your littium keeps operating so in the long run, lithium is cheaper |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:50pm On Mar 26, 2022 |
solasola: That is a major project and should require significant planning but very roughly speaking: - 5 units of 8kw hybrid Deye inverter - assuming you get your load powered from sunlight between 10am and 3pm means you need 9hrs backup from battery add 1 more hr to take care of intermediate timeout within sun period which makes 10hrs backup time. Using 25kw load means you need at least 250kwh of battery storage. - To charge a 250kwh bank you need at least 85kw PV (using 3x name plate generation) add the 6hrs direct from sunlight to load do another 20 to 25kw PV.... So 110kw of PV is required All the above are very very rough estimates and it has not even factored in cabling and excess PV. It's a multimillion naira project Sir/Ma 4 Likes |

Original 1.5kva 12v eastman inverter needed. State your Price and drop your contact. If there is a better inverter, point it out here in the forum so I can make an informed decision |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 5:56am On Mar 27, 2022 |
bbally: My Lg inverter Ac, draws about 680w on normal mode, but 900w on super cooling mode. It drops to about 500w after about 6hrs of running, in an enclosed space. At 900w, for a 12v system, thats about 80amps. So be sure you battery can support such a huge draw. Remember 0.1C for leadacid and 1C for lithium. Lithium batt bank is genetically predisposed to carry heavy load 3 Likes |

Hi guys I have a generator 9-10 kva that I use to power my 2kva luminous cruze inverter. The Generator is about 10months old. Recently the generator stop charging my batteries 2 pieces of 240Ah but NEPA still charges when the voltage is not low.my technician said I would need external 30amp charger which will work for both generator and NEPA.please guru I need your advice |
Re: Solar Energy, A Complement To FTA by SolnergyPower: 3:38pm On Mar 27, 2022 |
Check the frequency of the generator. This may most likely be the issue. The frequency should be 50Hz otherwise get a generator technician to tune it. Changing the generator AVR also can fix the frequency issue. We're waiting for your feedback. rowon: |

Re: Solar Energy, A Complement To FTA by Dam5reey(m): 5:00pm On Mar 27, 2022 |
bbally: 80a on 400ah Lead acid will kill them sooner.. 1400w is not sufficient, consider times 3 of this.. and upgrade to Lifepo4. I will not recommended this kind of load on 12v 400 lead acid 2 Likes |

Re: Solar Energy, A Complement To FTA by mcTrinity(m): 9:15pm On Mar 27, 2022 |
Good evening house, Anybody with an idea of any device capable of converting split-phase 220VAC to normal single phase 220VAC source. After installing a Felicity inverter, I discovered every other thing in the house is working fine, except the ATS (used, with a timer, to control freezer operation) . With NEPA, the ATS outputs fine, but with inverter output, it's "vibrating". Never experienced such issue with other inverters. I was later made to understand that Felicity inverters have split phase output source, hence its not compatible with the ATS coil. Anyone with idea of a device that can serve in between or with an alternative solution... Thanks. You can also kindly reach me on 081-8-2625213 (Whatsapp) |
Re: Solar Energy, A Complement To FTA by solasola(m): 9:45pm On Mar 27, 2022 |
Thanks baba. Figure for this will run to 100m or more and even no area for the panels. Hence cutting down as the major loads won't run concurrently. Settling for 10kW load running from 10am to 5pm. Battery ,.,.,.....30KWh lithium 2pcs of 8kw Deye 20kW PV... This should hold. Any further inputs ojeysky: 1 Like |

Can anyone point me to a reliable/trusted solar panel installer in the house that can install a 2 panel (300watts each) solar array in Yaba Lagos? I bought the panels and charge controller but my electrician dey fear to climb roof . Its a flat in a story building. Thanks. |

Moneyboyz: Weldone. Lithium into the mix makes things all the more interesting. And battery tech is ever improving constantly as researches do not stop. I recently read about Tesla's consideration of Manganese to make batteries as it is in more abundance than Nickel which is required for 18650s (even though he currently uses the 18650s for his premium long range line ups while the LFP is reserved for his low range BEVs). Then there is this solid state battery being touted by Toyota research team and they are already trying it in their vehicles. It is said that it can be recharged from zero to eighty percent within five freaking minutes! Can you include the minor details of the costs of some of the items you used: the spot welder, the BMS, the 18650 cells from Alaba etc for the sake of readers here? And that Roofer brand of 18650? The name sounds new. Can we see a picture of it? Moneyboyz: Okay. So each battery comes to around 850 naira per cell. |

abilityC: And risk getting prosecuted by the government for "creating a micro dam" and trying to create an easy life for himself and possibly open the eyes of other citizens. I don't think that option comes with the freedom associated with solar generation which has a much less, nearly negligible footprint on the environment. If no be for God, the government would have legislated to have all solar enthusiasts prosecuted except they seek operating licences which has to be regularly renewed. Then you will see them create a task force that will be invading neighbourhoods to check roofs that have panels on them. They will count the numbers of panels and use that to calculate the rough estimate you will pay. Failure to pay, you risk getting your panels carted away, while the task force operatives will auction them to themselves at ridiculous prices or to other buyers while they keep the money/auction proceeds for themselves. Some may decide to start making illegal money from there as they offer you to pay an off the record stipend for them to "look away" so that you get to escape paying for an operating licence or its renewal. Boom, another illegal money making rachet is created. You will also start seeing a few neighbours who will start ratting out to the government those in their streets that are installing panels. I can just think of a dozen ugly, discouraging scenarios that can crop up from such legislation.l, as far as Nigeria is concerned. And creating a mini dam is not as easy as it sounds. The finances, the environmental impact assessment of such structure and the resultant wàhálà from the government is not what one individual can bear, well except you are Dangote who is a government backed "businessman". 2 Likes |
