Folks anyone with a 120v 2p DC breaker with minimum of 60A for sale? Something similar to the attached

dapsyra: Most 24v inverter tops at 30 volts at which the inverter overvoltage protection kicks in. How would one use it with that kind of inverter and maximise the capacity that the pack has to offer? |

ojeysky: Too bad. It's the 16amp that I have as spare, 63amps already in use. |

dapsyra: You took 2 packs and continued the series connection from the 1st to the 2nd pack while also removing the last 2 modules from the 2nd pack then. Abi you just removed everything and arranged to suit your purpose. I love this DIY stuff. |

Guys, please where can i get ONLY the battery in the below picture? I think it is a 250,000mah and comes with an adaptor. I nicked the pics from a thread here. The owner is quoting an arm and a leg, so i am considering getting it in the open market to save some cost. Please advise, guys. Thanks

ceaser: About 90% of the battery capacity is between 2.1v and 2.5v. At 30v, the battery is 90% full |

ceaser: Wew if it was at least 30A I would have managed it |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 7:13pm On Jul 22, 2020 |
essegis:The 20Ah cells were used "as is". Just connect 2 packs in series and charge to 60v The 55Ah cell came bare. This are the ones we built into several banks of 22s and also charge to 60v The 20Ah banks and the 55Ah banks were all connected in parallel to a busbar 1 Like |

ojeysky: Your demand isn't under general demand ! You feel voltage won't work for you but will work since under safe amps if interested tho .. Cheer's |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:48pm On Jul 22, 2020 |
simydan: Naa I need something with 120v or max 140v. Similar to attached. The inverter it's to be used on is 145v max

Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:51pm On Jul 22, 2020 |
kiekie1: I would have thought that the lower voltage breakers will be what should be in "general demand" since many people use low VOC CC. It's strange that people will use a 500v breaker on a 145v CC |

kiekie1: It's okay if you term a logical reasoning that way, but if you care to educate, then you may want to explain why low VDC users would go for high voltage breakers instead of going for one that meets their CC max voltage |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 10:29pm On Jul 22, 2020 |
cooldipo: Yeah, most decent cc will reduce charging power as a battery gets full. The problem is when it senses that the battery is not full, it will try to force in the max current to the battery. This wouldnt be an issue if your array is sized properly, bit if your array is oversized, and you hv lead acid battery, it becomes a problem, as such batteries shudnt be charged over 13% of their AH rating |

@Ojeysky - people in Naija generally buy what they see available and sellers too generally sell whatever products move well - matching circuit breaker and other devices to the intended purpose is strictly the passtime of the well informed. Just three weeks ago or so, I was at a client's where their ATS guy (says he was Schneider trained) said that the 'circuit breaker' he had installed would protect the house from line voltage surges from the supply transformer. Of course I told him we could put this to the test as I had a variac/auto-transformer setup to generate from 150v to over 300v for my equipment calibration (I was gonna explode a couple of incandescent bulbs with voltage above 280v) He quickly back tracked and later put an SPD and a AVS/AVR upstream of the loads. The key parameter with a circuit breaker is to match the amps rating to your application. It is typical to size up to 125% of maximum current you expect to pass to avoid nuisance tripping. Too much headroom e.g 63A breaker used where you needed 32A and that breaker will never trip to protect the circuit except in case of severe faults e.g short circuit. For voltage rating of a circuit breaker you need to ensure your application voltage is well within the circuit breaker's operating voltage range so if your application calls for 145v then the breaker must be rated for at least 145v - some upwards headroom at least 10% is desirable. A 250v rated breaker would work in a 145v circuit but you shouldn't use a 90v rated breaker in that same 145v circuit else it may misbehave. ojeysky: kiekie1: Trippledots: 3 Likes |

NiyiOmoIyunade: Thanks a lot for the education, can only happen from a few minds such as Sir NiyiOmoIyunade Just one more thing as I have not been able to find a 250v locally either does it mean it's still fine if I get 500v with an appropriate current rating? 1 Like |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:49am On Jul 23, 2020 |
I believe this should be very okay - your application is well within the operating voltage range of a 500V DC circuit breaker. ojeysky: 1 Like |
