I think the recent increased penetration of the high voltage hybrids automatically made Ojesky think its one of those. It will be good to state the inverter / CC specs when asking for assistance o. To avoid stories that touch. Dollar don coss Peterlove11: 1 Like |

litaninja: Lol....I actually asked for CC spec in my original response to the Bro, unfortunately he didn't include that and I didn't pay attention to it either when he responded to me. Meanwhile 4s 270 will definitely be of no use to high Voc o..... those ones are just warning up at 150Voc |

Please house, is there a way to bypass the float charging in lithium profile of Epever Triron3210? I learnt LFP aren't supposed to be floated, but the float voltage is set at 13.8v and doesn't work if zero (0) is typed in place of 13.8v. I would like to know if this would have any adverse effect on the performance and/or life span of the battery. Thanks. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 4:06am On Jan 22, 2021 |
IYGEAL: Is that the minimum it can allow? I now use 13.5v as my float value but when I had MPP which had a known float bug I used 13.8 then drop the voltage back to 13.5 once battery is above 95% SOC (it's automated). It's okay to float just don't leave it on float at high voltage for a long time. 1 Like |

ojeysky: If I reduced it, it asks to reduce/increase some other figures. They follow a certain rule and are set by default when you select the battery chemistry. Floating starts only when the battery is full and is probably there until the sun goes out or enough loads to bring the battery back to charging State are added. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 11:22am On Jan 22, 2021 |
IYGEAL: If you are certain that is how it behaves (as that's not the case with certain experts) set it to 13.5. You may go higher to say 13.7 if you do daily discharge on the battery |

olopan: Is that 4s3p config for the 48v system? |
Re: Solar Energy, A Complement To FTA by ceaser: 6:45pm On Jan 22, 2021 |
Peterlove11: 2s4p ke?! For a 48v system from 270w panel, bro that is suboptimal. I have a 24v system with 320w panels (2s2p) and 350w panel (2s1p). The open voltage is around 85v to 90v and while on CC comes around to 70v to 75v. From this, using 2s for your 48v system will give poor harvest for the open voltage will not approach the level necessary to power your CC to charge the batteries adequately. Least you should go for with your 270w panel is 3s and 4s if you have a controller with open voltage approaching 180v. Peterlove11: Change your config to 3s first before thinking of managing PV production, for you may end up getting an impressive harvest doing that that augmenting with PHCN may no longer be a strong neccesity. |

Re: Solar Energy, A Complement To FTA by mank1234(m): 8:04pm On Jan 22, 2021 |
NiyiOmoIyunade:Thanks for your feedback. I think you got the strange figures because your input are not real world values. Firstly, there's no way total startup power of all your appliances will be just 2000W while you consume 750kWhr in a month. Secondly, it's near impossible for you to consume an average of 25kWhr in 24hrs(from your first input) and your night consumption will be as much as 24kWhr. If you input real world values, you'll get real world answers. You can offer where corrections is to be made if you notice any and we will implement it. Thanks once again for your feedback. |

Re: Solar Energy, A Complement To FTA by mank1234(m): 8:59pm On Jan 22, 2021 |
essegis: Are you saying that it's possible to consume 1kWhr in the day and 24kWhr in the night and your total appliances startup power is 2kW only? Please kindly list equipment scenerio that can possibly make the above possible. Edit: (Microwave, pump, air conditioner alone dwarfs the 2kW load). For you to do 25kW a day, there's no way you won't have some of those high energy guzzlers. So the 2kW total equipment surge is grossly under quoted. 1 Like |
Re: Solar Energy, A Complement To FTA by essegis(m): 10:01pm On Jan 22, 2021 |
mank1234: 1kwh in the day and 24kwh in the night is not what I meant. I meant as a total it is very easy to do 1kwh every hour for 24hrs to give 24kwh. If you have one of there NEPA prepaid meters then you will understand what I'm saying better. |
