bassdow:boss can I use panels for charging phones direct |
Re: Solar Energy, A Complement To FTA by dollarnaira: 2:27pm On Apr 30 |
Eagba: 100% possible. But only sunlight. Days of rain na bad market. Ran a rechargeable fan with it yesterday without battery. |

Please house how reliable is pow Mr 80a solar charge controller

Re: Solar Energy, A Complement To FTA by mctfopt: 2:37pm On Apr 30 |
Dam5reey: That's impressive to see that high VoC of the MPPT and low starting voltage. Most high input voltage inverter requires high starting voltage to run the MPPT controller. |

ayo1984: Used the 60A. Not bad. |

dollarnaira:Ok . Like what wattage of panel is advisable for an average of 25 phones charging simultaneously. Later she can get batteries |

Re: Solar Energy, A Complement To FTA by bassdow: 2:45pm On Apr 30 |
Eagba:what you mean by "DIRECT" ? If you mean by connecting the phone directly to solar panel, without any thing in-between, then it's a NO |

dollarnaira: How did you do the connection? |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 4:18pm On Apr 30 |
Eagba: You want to charge 25 phones simultaneously, that's 250 watts of energy if each phone takes 10w. that's base charging 2A 5V. Plan at least a small battery to serve as a buffer for cloudy periods. Plan for LFP backup 12V, 50AH, or lead acid 12V 100AH will do for a start. 500w Sachet inverter, you can't run DC-DC due to the number of phones. 12V 60A PWM charge controller, 2PC of 180W Solar panel. with 500K you will reach somewhere! 1 Like |

Good evening to y’all great people Please I’m curious about something and I hope y’all can clarify it. What should be the battery full voltage and low battery of a 24V LiFePO4 battery pack? Due to my knowledge, I thought each cell can attain 3.65V at fully charge and 2.5V while low? |
Re: Solar Energy, A Complement To FTA by isangjohnson: 5:40pm On Apr 30 |
RickyM:The allowable voltage range that will not harm the cells is 2.500v-3.650v. The working voltage range is 3.000v-3.400v per cell. Charging above 3.425v per cell gains you nothing other than tear and wear because there is no appreciable stored energy above that voltage. 6 Likes 1 Share |

Sapiosexuality:To the best of my knowledge, there is no specific time or duration. Some may last for two months, some may last for one year, some may last for five years and some may still last beyond ten years. The durability depends on many factors including the quality of the products and the maintenance culture of the end user. 1 Like |
Re: Solar Energy, A Complement To FTA by bbally: 6:12pm On Apr 30 |
Dam5reey: It is true that with 30v the inverter will register solar input but the spec design and requirements for these high voltage inverters differs from model to model. Yours might require 120v for nominal operation but his inverter requires best nominal volt of 240v. Correct me if am wrong, we are all here to know more. See attached

Re: Solar Energy, A Complement To FTA by durodee(m): 6:37pm On Apr 30 |
Sapiosexuality:Like for many inverters or electronics it depends on many factors- Quality of the inverter itself, protection provided at installation against grid surge, lightning strikes, types of loads its being used for, ambient temperature, duration of use etc. The worst hybrid I have used so far (SOROTEC 5KVA range) lasted about 3 months before suddenly packing up, most will last years but unless you are using the high end types, I will budget 2-4 years on average before you have to repair something . The National grid with its "dirty" voltage and current is a major enemy. Off grid, the worst enemy is the element- heat/fan stoppage , lightning strike etc, etc 1 Like |

Dam5reey:Thanks , but remove the battery in this equation. Is there a way around? Let cloudy day be cloudy. 1 Like |
Re: Solar Energy, A Complement To FTA by isangjohnson: 7:19pm On Apr 30 |
durodee:Apart from the quality of products, which may be a factory designed fault, every other thing you listed here is the false of the end users. Take a look at the heating temperature of the inverter via the attached picture. Very few people do create time to open the sides of their inverter and clean the dust/blockage. Some people do not even remember it till they pack the inverter. This blockages do not always create room for air circulation/ventilation inside the system as the fans are blowing, whereby creating unnecessary internal heat within the closed system.

isangjohnson:There is still energy stored over 3.425v, I normally stop charging at 3.450v |

kwende: Depends on your load. Mostly 5 to 6kw inverter. Next question should be choosing between transformer based inverter or chopper based? Cause 5M no b small money, @bassdow @bigbrovar and other experts make una pls come give expert advice. Anyone with experience with transformerless using iron and AC for like 2yrs no issues.... |

Re: Solar Energy, A Complement To FTA by Danibestguy: 8:49am On May 01 |
Hello. I have a 24v 100ah lifepo4 battery. Constant load - 240w which is just a fridge and a fan. I want to get an inverter to match it. I'm also planning on getting panels later on. Please note that we get up to 8hrs of grid light daily. Is it advisable to get an hybrid inverter ? Considering that I'm staying in a rented apartment(limited space), will 2 500/550w panels in series be enough? Budget is 500k. |
