yea not small to charge the batteries, but powering the freezer [even] during the day, means the Solar panel is expected to provide a bulk of needed current hence my saying even the solar panels are small, irrespective of wether chargeController is PWM or MPPT. You need consider loses both from chargeController, Inverter, Cables, even the panel sef might be overRated, + output of the solarr panels ain't often always at optimum levels. trust me, those batteries no go last long because they would be overWorked like Nigerian private school teachers 1 Like |

dacool1: na to avoid such inconsistencies, I automatically see such setUp as too small to power appliances such as Airconditioner, Refridgerator, etc. it's grid tied (NEPA / PHCN) but how consistent is are they. Client wouldn't know how to economise between days of prolonged power failure from NEPA vs days they provided light over half of the day. What happens days when the weather is too hot (too much sun no mean say solar panels go provide plenty current Ooo) or we have shorter day or when so much dust have covered the solar panels thereby further reducing output. what about days they might not remember to quickly turn off the freezer, or they have something in there that requires preservation, and the freezer is not yet frozen, you see them deciding to run it 2 or 3 more hours just so the items in freezer don't go bad. of course they would believe it's just that one time. See eh, edge cases plenty hence by the time you put a lot into consideration, you go just overSize am |

Drgreatone: That's P=IV hence 109/19.5 = 5.58 ≈ 6 Amps. This would/should work since it's same voltage with my 30-inches but the current draw of yours is higher and that might be an issue but doesn't hurt trying. Mine is 19v 1.8Amps and works flawlessly. youurs should work but your current draw might mean it either doesn't work, or work but trips off sometimes (probably if you increase volume so much) or doesn't work at all. Once again, doesn't hurt trying since all it would cost you is a couple of minutes. I have 2 TvMoniitors of 24-inches, and 30-inches. bigger screen/pixles means more current requirement. Should it not work, and you still want to use current lower than PHCN rating of 240-volts, You could boost it up to 19.5 volts and it would woork as if it's connectted to NEPA. iif to say na me get am, and I want to be adventurous, nna to do 2pcs 12-volts batteries in series gives 24-volts hence 24 - 19.5 = 4.5 BUT one can't do such without knowing the tolerance of the appliance. try the 12-volts battery first and see if it works, and works well. I have coore i5 and core i7 laptops but I uuse thhe core i5 most times, even when the core i7 woorks flawlessly on 12-volts also. My reasoning is, both works, but thhe core i5 draws lesser current compared to the core i7 |

I would try make out time to share thhe easiest way tto boost 12-volts to 19-volts. You don't even need know how to design circuits sef or mess with circuit boards. 3 Likes |

oloet: which he's yet to do. moreover, fridges and freezers have capacities. i might have table top, while you have chestt freezer, while thhe next person hhave those old school power hungry freezers. at end of the day, if you like, run ya thing using 1.5volts tiger battery if it works for you |

bassdow:I'm still finding it difficult to understand your points. We're talking about practical here.... What will make 160ah 12v lifepo4 battery attached to 2 pcs of 345w Jinko pv with the support of nepa light to die fast? Grid tied system is different from off grid system. I've been running off grid system for two years now with 4.05kw era pv charging my 15kwh battery bank to full before 3 o'clock everyday except on raining seasons, even with the use of electric cooker, microwave, iron, freezer, ACs, TVs, pumping machine. I discharged max of 40% every night.... If I was to run a grid tied system, about 2.5kw pv would have been sufficient for me. NB: Every system needs management and understanding. Once you know the capacity of your system and you're ready to manage your loads, you're good to go. 1 Like |

isangjohnson: The initial comment never mentioned GRID was involved and I responded accordingly. since NEPA is involved also, and the duration of power failure is short, then I would say no problem |

bassdow: Got a queer question please. Is there any way to connect/soldier a UPS or car battery directly to the motherboard of regular AC phone chargers and it'll work? I want to charge phone directly from battery bypassing need for inverter, but there fear the battery may blow the phone |

Re: Solar Energy, A Complement To FTA by bassdow: 10:07pm On Dec 01, 2023 |
oweniwe: phones charges at most 5-volts, your UPS batery is mostly 6-volts or higher. car batteries are 12-volts. You wan fryy your phone be that. Moreover, taking current directly from the battery, is not always good especially if na Car battery as the output could be very dirty. What I would suggest is, if your chargeController have USB port, make uuse of that or if you have laptop or TV that has USB port, make use of those or buy Car phone charger (which is actually an inverter but outputs CLEAN 12-volts) and connect that to your battery. mind you, Car battery ain't meant for deep discharge like solar batteries are. |

Drgreatone:a boost converter will do the work if you are using a 12v battery while you need a buck converter if you have a 24v or 48v battery. I personally will advise that you use your system as it is as the energy you are saving is not worth the stress |

Penuelseun: For me, it's 100% worth it. For him, thanks to his 50-inch Tv, might not 100% worth the stress BUT it's a oneTime stress na. no be everyDay stress. And takes less than 15-minutes. what I would say is, if He has other heavy things e.g AC, fridge, etc connected to his Solar setUp, then He shouldn't bother himself except he just wannts to prove it works. |

Please what is the actual capacity of this AC in watt? I'm trying to check if 8 to 10kwh lifepo4 battery can power it for 4 hours. I guess this is 2hp. Someone wants to power it occasionally for about 4 hours and this will happen only when there's a visitor probably in the evening time.
