generationz:1. The Battery is a used one. 2. That is not stabilizer but a stabilizer casing to house my Homemade inverter. |
Re: Solar Energy, A Complement To FTA by microgiant: 10:25am On Aug 10, 2019 |
generationz: Bought them at a ridiculous price (N5K each). They were used for a project, after the project the IT guy presented a proposal for maintenance until they will be needed again, but management thought it wasn't necessary. So the IT guy decided to dispose of the batteries. I came to the party very late and got the four. The used one was to complete as the unused ones had already finished. If I knew the value would have pressed further and could have gotten used ones at 3K max. Now none available. I bought them to use with my laptop, but unfortunately the power port was bigger and didn't fit my laptop. The LiFePo4s were forgotten after I did some research online, read of issues with charging etc, and care. I only picked interest in making use of it again after seeing Dishtech's responded to your post, with the pictures. Where I live public power supply (days without power) is very poor so charging with that is ruled out. Imaging we are using 3K credit on prepaid meter for 2months (2 1-bedroom flats, 3 shops and even the water pump is connected to our meter) there is no bypass connections. Hope restored with solar charging. |

Good day house, I am building a solar dryer as my final year project but I have the following issues (a) I don't have an idea of the size of panel and battery that can feed the dc fan (b) the cost of the panel, solar charge controller, dc battery and dc fan (c) I will appreciate if I can get somebody in Lagos that can supply the components to me as I live in the northern part of the country Attached is a sketch of the dryer thanks

Re: Solar Energy, A Complement To FTA by lexi28(m): 11:38am On Aug 10, 2019 |
aorseer: hi, FIRST AND MOST IMPORTANT QUESTION: what is wattage of your DC fan? the answer determines how you will proceed! cheers. |
Re: Solar Energy, A Complement To FTA by aorseer: 12:03pm On Aug 10, 2019 |
lexi28:Thanks for your response. The DC fan is a 12v turbo fan. I guess it's 24watts |

mctfopt: mctfopt Thanks alot... For the spd, have seen online that is connected like a breaker but no off and on switch.. does it still need to be Connected to ground. |
Re: Solar Energy, A Complement To FTA by mctfopt: 12:29pm On Aug 10, 2019 |
Easylearner: You may really need to get the services of a professional to get this properly done. Anyways, a surge requires a good earth to work. Take a look at this YouTube video to see how it works. https://www.youtube.com/watch?v=tfXoOfipO08 |
Re: Solar Energy, A Complement To FTA by Easylearner: 12:32pm On Aug 10, 2019 |

aorseer: hi, are you sure? the volume of air pushed by this 24w fan, is it adequate for the job required as depicted in the diagrams shown? anyway if that's wattage of the fan, then the rest is easy. load 24w/12v load current consumed:24/12=2amps 1nos 24w/12v DC fan 1nos 150w panel 1nos 10a pwm controller 1nos 65ah/12v battery calculations: duration of load :12hrs Ah consumed : 12hrs *24w/12v =24ah depth of discharge on battery: 24/65*100= 36% (good). 2 days autonomy. panel current : 150/18v = 8.33 (typical value) you expect practically 70% of this value = 5.83a C/10 rate (optimal charge rate) for the battery is :65ah/10h = 6.5a. 5.83a is pretty close to that. due to the fact that you said your location is in the north, you can expect better. typical costs: 150w panel >= 25k, chinko panels are cheaper. some for as low as 19k. 10a pwm charge controller (generic brand):<= 5-7k 65ah battery: 25-47k. (long brand is the expensive one, Chinese batteries cost less.) 24w DC fan: Alaba is your best bet. it is a student project, you are required to show working proof of concept. no need to spend over the top for high end gadgets. cheers hope this helps. any other questions, post them too. best of luck. once again I hope vendors here can give you a student discount. lol. 1 Like |

Easylearner: first of all. confirm that the earthing in the house or location is OK. the SPD has 3 terminals, +ve, -ve and ground. if you have a common connection for the DC side of things, like a bus bar. you connect a wire from the positive side to the Positive terminal of the SPD, then connect a wire from the negative bus bar to the negative terminal of the SPD, then connect a wire from the ground terminal of the SPD to a working earth connection spot. the bus bar makes this connection easier, but it you do not have one, locating the common points maybe confusing for some. that's all that is to it. if a surge occurs on the DC side of the system, the SPD "diverts" that and prevents the proverbial white smoke from your controller. 1 Like |

generationz:For availablity of power at shorter Life is the deep cycle battery but longer life is the LiFePo4 battery that is, 1. Safe usable energy for the 48ah at 80% Depth of discharge (DOC)= 48ah X 12v =576wh - 20%SOC( i.e 0.2 X 576 =115.2) , therefore 576 - 115.2=460wh. While 2. Deep cycle battery at 50% DOC= 100ah X 12v X 0.5= 600wh. BUT a. Lead battery has shorter Life cycle of <500cycle 50%DOC while LiFePo4 battery has longer life cycle of more than 2000cycle at 80%DOC. b. Traditionally Lead acid battery always want to be charged at each cycle. If there are not fully recharge, there are considered to be in Partial State of Charge which causes the battery to be sulphated Leading to premature death of the battery while LiFePo4 battery survive in partial state of charge. c. LiFePo4 is lighter in weight than Lead battery. In conclusion I will prefer if you have two of that 48ah it will give you the energy requirements that the 100ah Deep cycle battery would have given and still last longer than the lead battery. 1 Like |

Dishtech: But thee problem is lifepo4 batteries are scarce in Nigeria and one can only afford the used one's for now. Olease if you know where I can get them I'll be grateful |

lexi28: I do not have a bus bar but what I have done in my case was to shove both the PV and SPD cables in the DC breaker input, I don't know if the SPD will still do it's work with such setup. |

eleojo23:How many amps charger or what's the capacity or type of battery u intend charging? |
Re: Solar Energy, A Complement To FTA by lexi28(m): 9:26pm On Aug 10, 2019 |
ojeysky: is your breaker a double pole breaker? if yes, then the SPD connection should be made to the breaker inputs. if no, the breaker positive is OK, just find a common negative to connect the SPD negative to, preferably not directly at the controller terminals or most likely at the battery negative terminals (depending on the connections you used). the ground terminal of the SPD should go to the common ground/earth you have. if you do not have a good ground or earthing connection, the SPD is pretty much useless. if you got all connections correct, even without a bus bar, it will still work. cheers 1 Like |
