ojeysky, ceasar and other lifepo4 users, how would you advise using a pwm cc to charge a lifepo4 battery? |

essegis: This one will be a state project not even local govt |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 7:33pm On Mar 31, 2020 |
BetaTechnicians: Unless you have the pwm already you are better off with mppt so as to maximise the panel capacity because lithium will typically want to get as much current as possible |
Re: Solar Energy, A Complement To FTA by mctfopt: 7:39pm On Mar 31, 2020 |
BetaTechnicians: To add to what has been said, you are better off with an MPPT SCC as most of it are customisable. You can change the voltage at which your battery charges, a feature which I doubt you'd get with most PWM. |

earthrealm: Okay if I get you well, you intend that the 2 extra panels will work only on needed basis. When the timer kicks the pump in, the 2 extra panels also get auto connected thereby increasing the solar power input and that way the batteries do not get overcharged. But I think that will only be possible if your existing SCC has not been maxed up already such that it can still accommodate the 2 extra panels, other wise, I'll suggest you get another small SCC that can handle the two new solar panels and get it booked onto the batteries. That would also mean you will use your existing inverter, abi? And I'm unable to get the link to view the pump o. |
Re: Solar Energy, A Complement To FTA by ceaser: 9:19pm On Mar 31, 2020 |
BetaTechnicians: Of course you can. LFP is not a voltage fad like lead acid which requires boost, float and equilibrium charges. If your PWM CC is user editable, then better. You just need to edit the max charge voltage to the manufacturer's recommended for the LFP. You may not have that luxury with PWM that lacks user editable options because you will only be limited to a boost charge of around 14.2v which is okay for your regular 12v LFP, but then that will be for a while as your CC will then drop to the 13.5v pre-set float charge at it tries to follow the in-built lead acid battery charging algorithm. Your charge voltage sustained at 14.0/14.2v till sundown is the best for a 12v LFP. You will not get the high efficiency from solar panel input that characterises MPPT with the PWM though. |
Re: Solar Energy, A Complement To FTA by ceaser: 9:25pm On Mar 31, 2020 |
mctfopt: I used a PWM with the first LFP I had and the SCC was user customisable. But of course I missed the efficiency that MPPT offers. I got that 30A PWM off of AE about 4 years ago and only used it for the first time late last year. Hoping to have an extra one, I have been scouting on AE for one with customizable options without luck. |

NiyiOmoIyunade: This is so true... for controllers that support it the setting the tail current is very crucial in determining and efficiently charging a lead acid battery. In my case I set my tail current to be 4MB which is 1% of my 400AH 24v battery bank. It is suppose to charge at level for 30 min at 29.2v at which point it switches to float charge. |

ojeysky: It's just a small setup & I don't see the need for a mppt cc due to cost. |
Re: Solar Energy, A Complement To FTA by BetaTechnicians: 3:09pm On Apr 01, 2020 |

If cost is a consideration, JUO sells a Fangpusun 100v 50A MPPT CC for around 40k. It is altogether an excellent CC in that class and suitable for 12v and 24v nominal systems. BetaTechnicians: 1 Like |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 4:54pm On Apr 01, 2020 |
BetaTechnicians: Hmm.....how small? |
Re: Solar Energy, A Complement To FTA by mctfopt: 5:13pm On Apr 01, 2020 |
BetaTechnicians: If your controller's output voltage matches that of your battery's specified charging voltage, then you are good. Irrespective of whether it has the feature where one can change the output voltage or not. But as you already know you can't beat the efficiency of an MPPT with a PWM of same make. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 5:34pm On Apr 01, 2020 |
NiyiOmoIyunade: Hahahahahahahah. Are you sure JUo sells it for 40k 1 Like |

ojeysky: I saw a 12V 50AH lifepo4 advert and was thinking of getting that, so just trying to get smaller peripherals for it. |
Re: Solar Energy, A Complement To FTA by BetaTechnicians: 6:57pm On Apr 01, 2020 |
mctfopt:sure but if a Gokada can take me to and fro, why disturb an uber? |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 7:05pm On Apr 01, 2020 |
BetaTechnicians: Okay that's indeed small I won't worry much about the type of CC then but if you are looking at increasing capacity in future then it's better to plan for future scaling by getting good CC so you just have to worry about panels and batteries in future. |
Re: Solar Energy, A Complement To FTA by Dudeonyx: 7:55pm On Apr 01, 2020 |
ojeysky: Hi, I'm new to this and trying to research as much as I can about solar systems so I can get a good system that will serve me well. From what I've researched about LiFePo4, a 50ah lifepo4 battery should be equivalent to a 100 ah lead battery since those only have about 50% usable capacity. If so this makes Lifepo4 batteries have the same price as lead acid for the same usable watt-hours. |
