Hello sirs, Please which would you advise to buy between a Pylontech UP5000 4.8kwh and Felicity 10kwh LiFePO4 battery? Or is there a better alternative within the 2-2.6m price range? |
Re: Solar Energy, A Complement To FTA by isangjohnson: 5:49am On Mar 21 |
AllyPolly:Pylontec battery is more superior than lifepo4 battery, hence the price difference. If the Felicity can give you quality lifepo4 battery with real capacity that can take you for 10 years, I would suggest you go for lifepo4 that has more usable capacity. REASON: In the next 8 to 10 years, another battery may likely come out that would be superior than these two and you may likely want to switch over...... If you were to compare pylontec 4.8kwh with lifepo4 7kwh at the same price, I would chosen pylontec. SUBMISSION:Human wants are unsatiable. |

isangjohnson: There exist a better Lithium Battery than LiFePO4 and it's called Lithium manganese nickel cobalt oxide. (NMC for short) Li[Ni0.5Mn0.3Co0.2]O2 as a Superior Alternative to LiFePO4 for Long-Lived Low Voltage Li-Ion Cells. NMC are good batteries, they just really hate high temperatures. It is already being used for over 2 years in cold regions. Lithium manganese nickel cobalt oxide (NMC532, CBP-52) has the chemical formula of LiNi0.5Mn0.3Co0.2O2 where the atomic ratio of Ni:Mn:Co is set to 5:3:2 in order to have high specific energy density, favorable rate capability for discharge and charge cycles, and provide a relatively cost affordable cathode active material for lithium-ion battery applications, especially for electric vehicles and other applications such as field drones, e-VTOL, and consumer electronics. We hope that we may have the opportunities to utilize some of these techs due to regional, natural and conditional restrictions. |

Good morning house.. Please I need some technical support on how to connect 4 pcs of 400W solar panels to achieve maximum harvest.. Available Apparatus 4 pcs 400w panels (specs attached) 60A mppt charge controller (Vmax 150volts) I think it has to be parallel/series connection. This is completely a DIY so any assistance would be highly appreciated.

Good day professionals, Can single core coleman wire (say 4mm and 6mm) be use? 4mm.... A output and input 4mm....pv input (about 8 pcs of 435w jinko solar panels) 6mm...battery to 3.5kva Growatt 48v ES. Is Growatt better than felicity? @dollarnaira @justemanuel @bassdow @penuelseun @johncosmos And others professionals I could not mention. |

Penuelseun:Bosss. Weldone. My installer did a 2s3p installation on my 24v battery 150max V CC I called him that I'd prefer a 3s2p. He said that my inverter and cc can't take such config. Please advice me Sir. Thanks. |

i knew it will come to this eventually, ....in the afternoon they will just turn off thermal energy source and switch to solar.

Bosses, I greet you all! I have 2 questions regarding how to wire solar panels together. I have 2 X 200W 12v solar panels that I am using with a PWM charge controller. It is a 12v battery. The battery builder told me to switch to an MPPT CC. I am planning to get the SMS 30A MPPT. However, I have an 80w panel that is gathering dust in my store. My first question is this, can I connect all the panels in parallel? ( 2 * 200w + 1 * 80w ) Or should I buy another 200w or use my 400w like that? My second question is also related to the first, will my new CC be able to handle the extra 80w or 200w additional panel? Thank you for the help. |
Re: Solar Energy, A Complement To FTA by Penuelseun(m): 11:40am On Mar 21 |
dbshaywhy:Better you use 6mm for your PV input and 25mm or 35mm for battery to inverter(16mm at the least) |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 11:48am On Mar 21 |
Ayomipoe: As long as the VMP is 18V for all panels, Connect them in parallel. it works. MPPT won't offer much unless you buy it for a Planned upgrade. 1 Like |

emmaniche:it should work with 3s2p, what is the VOC of your panel? |
Re: Solar Energy, A Complement To FTA by emmaniche: 12:14pm On Mar 21 |
Penuelseun:That I can't confirm, but each sud be about 40voc! |
Re: Solar Energy, A Complement To FTA by Ayomipoe(m): 12:21pm On Mar 21 |
Thank you Boss! The battery in question is 100ah, should I continue with my PWM? I was told that I could get more charging efficiency from the current 400w on the roof by switching to MPPT. Should I add more panels? Dam5reey: |

dbshaywhy: 4mm AC OUT (LOAD) 6mm AC IN (CHARGING AND LOAD BYPASS) 4mm PV (DELIVERING ABOUT 14Amps @ about130Volts DC) 35mm FOR 48V BATTERY For Growatt vs Felicity: Growatt Is better, There are Felicity models that beats Growatt but are not for African Markets. 1 Like |

Re: Solar Energy, A Complement To FTA by bassdow: 1:24pm On Mar 21 |
dbshaywhy:we don't know the distance, neither do we have any idea of your battery's rating. Either way, Single core wires often are much better than those of multiple core, but they also cost more than those of multiple core and it depends. of course, the thicker the wire, the better hence if you have to choose between 4mm and 6mm, it's always gonna be 6mm. if you can afford something much thicker, please do else just manage the 6mm. For Solar, would suggest going with multiCore cable. Depending on battery size, might be better using thicker cable to connect the batteries to inverter. As for "if groWatt is better than Felicity" , let me leave that for those into it. |
Re: Solar Energy, A Complement To FTA by bassdow: 1:40pm On Mar 21 |
Ayomipoe: the cost of MPPT doesn't really justify for such a small setUp. except you have plans of upgrading later. instead, would suggest buying those fake MPPT - they are PWM but marketed as MPPT. Some despite being PWM, are kinda better than most PWM in the market. your battery is 100AH, while your solar panel is 400w. That's more than enough for the battery already. any PWM should be enough since even the battery capacity is small. 1 Like |
