survemeka: Haters get your facts correctly, he only honoured an invitation by CAF as Enyimba FC state Governor. Google it! No haters, the man simply do not know what governance is all about. I'm not even into the PDP or APC bullsh!t that people often bandy about here. He is simply not doing his job he was elected to do. If there is a state of emergency repair or meeting that he was invited to in part of his state, the possibility of turning it down while claiming to be "busy" is there. Many of our leaders behave this way simply because the system allows irresponsible people to lead. It is a pity. |

ojeysky: Sorry I think I may not have asked my question correctly, is an SPD same thing as circuit breaker? No, an SPD is a surge protective device. It prevents surge or instantaneous current either as a result of fault, thunderstorm, etc from damaging our equipment. |
Satellite TV Technology › Re: Solar Energy, A Complement To FTA by mctfopt: 6:00am On Jun 24, 2019 |
ojeysky: Thanks I have an SPD that has 600Voc, is it the same thing with what you've stated above? Here is the reference of the SPD I have:
https://www.otowadenki.co.jp/eng/products/pdf/LS-YPV6012S%20%20LS-YPV10012S.pdf
Regards The calculation is just for the setup I described. You can always interpolate with your own specific setup data to get what you require. I hope this helps. |
Satellite TV Technology › Re: Solar Energy, A Complement To FTA by mctfopt: 10:04am On Jun 23, 2019 |
ojeysky: Yes and the distance is about 12 meters. Please kindly also recommend if I should get a circuit breaker and the specification. Fyi I already got an SPD. Thanks OK. I'd suggest you use a cable up to 10mm, just buy the flexible copper type mostly used by welders. The Voc determines the minimum voltage rating of the disconnect switch: for a 14 series 36v PV system the breaker disconnect voltage will be 14 × 36 V = 504V, so a 600V dc breaker will do. As per the current, if Isc of each panel is 8.5A as they are in series the maximum current obtainable is 8.5A, you'd multiply this by 125% which gives 10.625A which you can round to the nearest standard current size of 16A. So you'd require a 600V 16A dc breaker for this configuration. |

ojeysky: Bump! The cable size you are asking of is it for the connection of the PVs to the solar charge controller? If yes, what's the distance between the PV and the charge controller? |

cute75: My inverter is Locally made....its a 12v/1.2kva inverter....it was tweak to carry my fridge if need be....I can set the output voltage....I notice that when the voltage was at 220volt my TV was consuming 55watts....Well my TV voltage rating is 100-230volts and so are all my appliances... so I reduced the voltage to 160v it dropped to 28watts, same with my home theatre....light bulbs 3watts from 9watts and still Bright...Its was made to be very rugged. Lastly, I can set the maximum output power: What I mean is that if I set it at 100watt, and the load crosses the 100watts the inverter automatically trips off and starts beeping...It also display the load in watts u are consuming....Variety they say is the spice of life Electric power P = IV where I = current and V= Voltage. If you reduce the voltage, there is a corresponding rise in current to maintain same power. Conversely, if you increase the voltage there is a corresponding drop in current; a principle that allows the use of small diameter wires to transmit voltages over vast distances with less drop in power. How did this inverter circumvent this basic electric principle? |

elvisdaniels: Dont mind that idiot that branded the guy a drug dealer , I was housed by the guys friend when I was studying in Malaysia , so I know him too well , He says reloads of all networks in Malaysia , since some people don’t have visa they are scared of going downstairs to pay load or do some bills payments . They guys does that and takes his commission , he’s known by over a thousand Nigerians all through cheras area so he makes money , he had to diversify his business and went into car rentals , he gets cars from the locals on a cheaper price and rent to Africans on a higher price and makes twice the profit of what he paid the locals , were talking of cars from 2014 to 2019 all new and his good with Chinese and Malaysia’ns each car rental a day he makes from each car 10k naira or more after paying the car owner that loaned it out to him just for a day ooo I’m talking about one car he rents 10 a day we talking about 100k He’s not into drugs that guy suffered big time in Malaysia RIP to him anyway a total loss to the family I always think people should know something before jumping to conclusions. He seems like a nice guy and Nigeria had just lost another one. Sadly, the police will just continue their business as usual with the culprits never getting caught. |

18650 Cells - You would have to order new cells from overseas which I think is almost difficult.
Laptop Batteries - Laptop engineers The second option looks cool. Thank you. |

feflo: Observation
I noticed that one pack performed better than the other pack. There was a voltage difference of about 2v between the packs. At a point one was reading 27v while the other 25v. I'll work on correcting this.
I also noticed that the lithium charges faster when compared to Gel or Lead acid batteries. Interesting, the low resistance trait of lithium makes charging it faster than our conventional lead acid batteries. I think bottom balancing the two lithium pack may help with the voltage difference |

Thanks Just like you suspected, the BMS may probably be incorporated into the control board. This is awesome, I'm on the lookout for a not-so-expensive lithium setup these days. So update the house on how it goes. Thank you. |

hotdealz: What is BMS? 
Well, below is the strange way I connected lithium batteries from "dead laptop batteries" to my rechargeable fan. The fan can now blow at very high speed for more than 24hours non stop. It's been working like that for 3 months now, no issues at all and I didn't use BMS anywhere.
I will never use that rubbish they call battery that came with the fan again! I wondered why they use the battery in the first place. Something that barely blows for 5 hours at the lowest speed.  Do you have a spot welder? I noticed one of those pink batteries that look like Samsung batteries were spot welded. How many of the 18650s did you use and what is the wattage of the fan? I'm also interested to know the voltage and amps of the charger you used for charging the batteries. I'm just curious about anything renewable energy so pardon me for the questions  |

wirinet: I agree that it depends on situations and applications. Imagine NEPA loadshedding your house to 1 hour supply per day. You virtually "download" your whole 24 hour electric usage under 10 minutes. Also imagine traveling long distance on an electric car and running out of charge. Would it not be a dream to be able to drive into a charging station and get a full charge at the same time it takes to fill a traditional petrol engine car. I love the charging rate. Of course, one can buy it if he can afford it. If it lives up to the specification, it'd pay for itself over time. But of course, anyone can always buy the type of batteries they can afford without breaking the bank. I may give this a try. Fingers crossed. |

wirinet: Introducing Lithium Titanate (Li2TiO3) batteries. These are future technologies for electric storage. They have a cycle of over 20,000 cycles and can be drained to 95% DOD. 20,000 cycles means 54 years if cycled everyday. This battery would probably outlive the owner. The draw back right now is the huge cost and the usual lithium chemistry issues. Yeah, you can even drill through it without any risk of explosion. I recently watched a youtube review of this battery in which the youtuber bought the batteries at Aliexpress at a cost of $276 or approximately N100k with free shipping for a lot of 6. The capacity was quoted to be 2.4V @30AH each cell. |
