Religion / Re: Please, No Sex Before Marriage Is NEVER A Scam by dave07(m): 4:20pm On May 31, 2020 |
Thank you Op and God bless you. I didn't see the thread and do not plan to see it either. You can be sure there many of such here on Nairaland always twisting God's Word and also attacking the Church or anyone that represents Christ. The gates of hell will surely not prevail and we pray for as many that have taken in the lies in that thread, to be delivered from the deception of Satan therein. The end is truly here, let the true believers keep their garment cleans, backsliders, know that there is room for repentance and those that have not experienced Jesus, come and encounter him, you will be glad for all eternity. |

Very interesting thread @op, thanks also for making it flow, else the lessons from the credit card discourse would have been lost. I feel what you have been through and am really encouraged by your decision, pls keep it comming though I know that work schedule will now make this not easy. However I would like to request a favour, from you, Justwise & other admin; kindly give us a thread on Tier 2 Visa applications, it is great to see that it is still possible to get sponsored to work in the UK from Nigeria.

Finally, all your solar-controller-battery will either work well or underwork if you fail to get your wiring correct. It is not just a matter of 6mm or 10 yards. For effective charging the rule states that the maximum voltage drop between the panel and the inverter should not exceed 3%. To achieve that you must get your cabling right or else, you waste money. Yes lightning protection is very necessary and the MPPT crew should know that at certain voltages and battery connection a surge protection is a must,( classical example-midnite solar). Above all Solar pass theory o, you must do it practically to know it as you should. To those asking for where to learn, start here and look out for practical installation. God bless you all. I'd be glad to answer question with the OP, I dey fear to call that name sef 2 Likes |

SOLAR PANELI agree 100% with poster who played down the emphasis on thw superiority of mono over poly. Maybe you should look at the doc he attached, It's high time we began to adapt the tbeories we ve read to suit our environment. That aside the issue of shading of the solar cell must be taken seriously if you are going to enjoy solar and correct information must be given too. There are standards in the solar industry, believing a panel of 200W @24V will give 7.25A is incorrect for instance. Check the name plate, do a little load test, a dc clamp on is a necessity for every DIY solar enthusiasts &prfessionals. Take the rated and short circuit current given at the back of the solar module very seriously. If for instance you see a figure of 4.5A and 4.85A given as rated & short circuit, then know that if the highset sunshine comes out and stay for one hour you wont get more than 4AH . If you have such light for 5hour with one module, assuming other things constant you woulld have harvested 4*5=20Ah with diffuse radiation and time of intermittent shadowing, the highest you'd do with one module will be around 26Ah. If your battery is 200Ah and gets depleted to say 50% dod, then you ve got a long way to go if you dont increase the number of modules you put out there. The fact that your panel has 200W doesnt mean it will give you 200W, that rating is at STC, look for NOCT ratings which are a little but more realistic and be mindful of temperature cos your panel performance decreases with temoerature increase, this is naija not America! |

CHARGE CONTROLLERSo sorry for your experience with the CC. If I can recollect very well, I have used the controller shown more than 5 times and had no issue, the user interface/digital display and higher amperage made it a choice for me over the morning star PWM and BP solar CC I gad been used to un the past. No, it is not nameless but was brought into the country by Roysolar ( A chinese outfit at Fedan plaza Alaba), the company started well with good product with outstanding quality but in recent time has been tilting towards the Alaba 'factor' but when you know what you need they will give it to you. Roy & Ezi Blessed are my only trusted vendors in Alaba. on MPPT, you'd be surprised that most product being branded online are MPPT by name & PWM by design, for most application in Nigeria, with the weather we have, I consider MPPT CC not necessary, maybe if someone will show me ab appreciable difference in the daily sun harvest using an MPPT CC and PWM CC in naija, I'll have a change of mind |

BATTERIESOn batteries the truth of the matter is that every battery produced has a life cycle that ia determined by the number of charge/discharge recorded. Most of the batteries in today's market do not come with this information because they are sub-standard, the likes of Zenith, Ritar, Luminous, etc are more favoured because by experience people have come to know them. I have had my bad days with luminous batteries though the good experiences have been more. The most expensive item with the shortest lifespan in an Off-grid RE system is the battery and you can't afford to throw money away just like that. But if you really really want to go for batteries try out the 2V or 6V high amperage deep cycle batteries. Even a fairly used (decommissioned ) set of this type will last you longer and better than the popular 12V modular brands 2 Likes |

Great thread and sincerity by the OP INVERTERThere is a need to clarify the two main types of inverters in the market today. 1. The high frequency inverters pure or modified sine wave, inexpensive and relatively light in weight. If all you want is lighting, TV, decoder, fans and the likes, then go for this. 2. The low frequency inverters, pure or modified sinewave, more expensive, bulky with more weight. If you are considering more inductive load like refrigerators, electric motor or compressor based application, in addition to the load listed above then you are good with thus. Most inverters in the market today incorpoates a battery charging element which enable you to recharge your depleted battery once there is mains power. On suitable brand, the indian brand I agree are more preffered though more expensive plus the fact that the input voltage range IMO are most ti es unnecessarily outrageous! For instance 12V is limited to less than 1KVA, 24V limited to 2.4KVA, anything rating higher than this goes for 48V, 96, and even 120V whereas you will still get an American Spec (e.g Outback) of 5KVA rating with 24V input. There are locally built inverter and Chinese inverters less than 2KVA that can easily be purchased within a tight budget and yet perform well. The only edge Luminous, Sukam & co have (IMO) is the availability of after sales repairs and services offered 2 Likes 1 Share |

Good step in the right direction, I only hope the tariiff is now cost reflective and the Discos can now get down to real work without haggling on poor tarriff again. I also think there should be more enlightenment on the part of the public and that Nerc ensures that Discos roll out prepaid meters asap and also carry out effective power distribution and not just revenue collection |

I take exception to the word 'vigilant' in that release. If they had truely been vigilant the man would be nowhere near that tarmac. Secondly the uunnecessary warning issued thereafter is a poor attempt at damage control or are we to assume that up till that point the 'vigilant' security personal had been allowing all manner of person acess to unauthorised places in the airport |

God be praised that she was able to come to terms with the Lord before her death, few have this kind of opportunity. It's a great joy to every believer to hear that this happened just before she died. The things of the Spirit will always look like foolishness to those who are perishing. A word of advice- Better settle with God now than allow a wicked person cut your life short while you are in sin, because if after killing you, the wicked repents and reconciles with Jesus, the fellow goes to heaven while you rot in hell.

Great challenge, good initiatives. Less talk and more action like this is needed Every other thing about the DC freezer can be locally sourced except the DC compressor. Some Chinese company bringing in the freezer deliberately removed any name plate info that can link you with the DC compressor manufacturer. Secondly can we begin to challenge engineering technicians to start getting interested in locally built inverters and also improve on the designs.

Computers / Re: Inverter Users : Lets Have Your Experience by dave07(m): 10:02pm On Jan 11, 2015 |
It's been quite a while but the thread keeps getting better My final question. I have a load of 1.5 kW that I would want to power for 10 to 11 hrs. I have a 3.5kVa inverter (48V) and 4 12V 200AH deep cycle batteries connected in series. How long would it last?With a load of 1.5kW your draw at the dc side is 31.25A, if you continue with this load for one hour, you'd have drawn 31.25Ah out of your 200Ah bank. Neglecting losses due to battery discharges and cabling and assuming you want to maintain a DoD of 50%, in order to lengthen your battery life, then you can only run this load successfully for 3hrs or 5hrs (worse case scenario & jettisoning DoD) before your inverter shuts down. To achieve your goals you would need at least another parallel string of 200Ah 48V to bring your storage Ah to 400Ah minimum. Alternatively you may work on your load, take lighting and some other load to dc with very low consumption, so that your overall consumption is considerably reduced. Remember power at the dc side of your inverter=power at the ac side (theoretically speaking and assuming minimal losses) consequently current draw is a ratio of rated power to voltage. hope this helps 1 Like 1 Share |
