Bros it has not since 2019 oo, out of about 10 people I installed solar system for using this 2kv inverter, its only one that had problem with it. The lower 1kv and 500 which doesnt have regulating fans are quite awful though. ajabani4allah: |

Please engineers if you have MPPT charge controller any need for buck converter |

My 24v easun 3kw arrived today, tested it with my 24v 7s 2.5kwh li-ion pack. Battery was at 28v, plugged a steam iron, and voltage drop to 26.9v. 1 Like

Penuelseun: Thanks I want to connect solar panel through MPPT charge controller to my li ion battery pack |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 12:08am On Sep 08, 2024 |
capnies:You don't need a buck converter if your charge controller can go as low as your battery absorb voltage, is your battery 12v, 24v or 48v? |
Re: Diy Lithium Ion Like-minds by Intellab(m): 3:32pm On Sep 09, 2024 |
Penuelseun:If I connect the built battery pack to solar charge controller, will my solar panel be able to charge it? |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 4:42pm On Sep 09, 2024 |
Intellab:Battery voltage? Solar panel voltage? Charge controller type? |
Re: Diy Lithium Ion Like-minds by capnies: 5:08pm On Sep 09, 2024 |
Penuelseun: Thanks, my battery is 12v ie 3s |
Re: Diy Lithium Ion Like-minds by Penuelseun(m): 10:56am On Sep 10, 2024 |
capnies:If your controller absorb voltage can go down to 12.6v, you are good to go, if not you need a buck converter |
Re: Diy Lithium Ion Like-minds by capnies: 11:23am On Sep 10, 2024 |
Penuelseun: Thank you very much let me check |

Who has 3s 60A BMS for sell or if you know where I can get it please let me know. |
Re: Diy Lithium Ion Like-minds by dollarnaira: 5:56am On Sep 11, 2024 |
Southboy:Konga |
Re: Diy Lithium Ion Like-minds by Ferdiwar: 7:31am On Sep 11, 2024 |
You can achieve this by replacing the wires from inverter output with the wires from inverter ON switch at the relay connection. ajabani4allah: |
Re: Diy Lithium Ion Like-minds by Ferdiwar: 7:36am On Sep 11, 2024 |
It depends on what you intend to use it to achieve. You can get the BMS from vendors here or AliExpress Southboy: |
Re: Diy Lithium Ion Like-minds by Southboy(m): 11:38am On Sep 11, 2024 |
Which vendor here sells BMS, I need it asap |

Re: Diy Lithium Ion Like-minds by eghos12(m): 9:28pm On Sep 11, 2024 |
Please does exceeding the Total watts oof charge controller does damage to it. For example 12v is(260 watt) for 20amps CC. And you want to connect 300w to it will it affect it. |
Re: Diy Lithium Ion Like-minds by Trippledots(m): 5:25am On Sep 13, 2024 |
Penuelseun: What if they are not 18650 cells? I saw a li-ion pack doing 57v top and 48v cutoff. What can be improved about that charging profile? |
Re: Diy Lithium Ion Like-minds by Trippledots(m): 5:27am On Sep 13, 2024 |
capnies: An MPPT is a buck converter at its core. No need. |
Re: Diy Lithium Ion Like-minds by Trippledots(m): 5:29am On Sep 13, 2024 |
Intellab: Bro, be careful around li-ion packs of. They are unforgiving if abused. |
Re: Diy Lithium Ion Like-minds by dollarnaira: 9:33pm On Sep 13, 2024 |
Trippledots: 14×4.2=58.8v max ( decreases lifespan though) 3×14 = 42v cutoff (38.08v for my trusted Samsung 26J). 1 Like |
