obinna37: Okay, do you notice any difference in battery voltage once the inverter is powered on? Do you have a clamp meter to check if any form of current exists between the inverter and the battery? In/out |
Re: Solar Energy, A Complement To FTA by obinna37(m): 8:02pm On Jul 19, 2020 |
ojeysky:yes I have done that, no current exist |

mctfopt:I use NEPA and solar |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 8:09pm On Jul 19, 2020 |
obinna37: And no difference in the battery voltage between when it's off-load and when the inverter has AC input? If yes then you may indeed have a faulty inverter. I once had a 1.5kva inverter, it stopped indicating the charge icon but it still charges the batteries. 1 Like |

mctfopt: What was the system voltage when you had the 114v Voc? 1 Like |
Re: Solar Energy, A Complement To FTA by obinna37(m): 9:19pm On Jul 19, 2020 |
ojeysky:yes,no voltage input in the battery, I think the inverter is faulty, can it be repair. |

obinna37: It's likely the charging section has failed. You have three options: 1) Repair it by a professional or open it by yourself and look for a fuse that is open. 2) Get an external charger. 3) Forget NEPA and use only solar. 2 Likes |

Good day all, Please can someone help me with a place preferably in Lagos that I can spot weld a pack of NiCD batteries. |
Re: Solar Energy, A Complement To FTA by ceaser: 5:51am On Jul 20, 2020 |
mctfopt: Hmmm. Interesting. Was the 114v a one off occurrence then or it's a constant? Also what is the usual common voc that you read on the CC, most times less than 100v? Can you remember the Voc of your panel? |
Re: Solar Energy, A Complement To FTA by mctfopt: 6:46am On Jul 20, 2020 |
ceaser: Used it for like a month. Decided no need stressing the SCC. This was due to the long distance (around 35m) the idea was then to reduce power loss and run smaller diameter wire. Had to upgrade wire and decided to run the smaller voltage with inherent higher current. |

Good morning House....I discovered my battery(luminous 220v) doesn't perform well under high current charging, which resulted to greatly reduced runtimes. Called the installer couldn't profer a solution until by instinct I reduced the default charging current and gbam the battery started performing like when I bought them. Has anybody experienced this 1 Like |

dapsyra: I know this post is old. Hope yoy don't mind. I see that you now use this LTO batteries. What has the experience been like? And what made you pick it over other Lithium chemistries? Thanks boss 1 Like |

obinna37:I have the same issue. The inverter will show that is charging but no increment in the battery voltage. The system is designed for grid interconnection with 1100W array to charge 24V200AH bank. The problem is that it is always in use during the sunny hours thereby leaving the battery empty in the night. |
Re: Solar Energy, A Complement To FTA by bbally: 10:12am On Jul 20, 2020 |
obinna37: can you help describe how you connect the inverter and solar to the battery bank because I guess the charges from the solar and the one from AC supply seems to be causing overload on the inverter panel. I might be wrong but expert can put more light for us and possibly a detailed diagram for proper connection for future experiment. |
Re: Solar Energy, A Complement To FTA by obinna37(m): 10:23am On Jul 20, 2020 |
ojtech8291:I don't think is the same inverter, my will show CH,as sign of charging,but now it doesn't show the CH,it just display 99.1 as the batteries are charge. This the inverter model below

Re: Solar Energy, A Complement To FTA by obinna37(m): 10:29am On Jul 20, 2020 |
bbally:normal 24v inverter,see pix below |
Re: Solar Energy, A Complement To FTA by bbally: 11:01am On Jul 20, 2020 |
obinna37: Hope expert in the house can give more input on my opinion above as my BTS inverter had a total shutdown and I was of believe that it was caused by thunderstorm but we I took it for repair it was said to be overload but I know my load was not more than 25% from indicator, so mind when to the connection with the solar. so, as I suggested it might be most of this inverter can not tolerate seeing charging current from another source meeting at the battery terminal. my 2kobo sense. I leave it to the expert |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 12:17pm On Jul 20, 2020 |
obinna37: whats the charge voltage setting of your cc?. if too high this sometimes affects the inverter. charging a battery simulatneously with solar nd inverter is possible, have been doing this for years, what i notice is that depending on which charging source has higher incoming charging oltage at any point in time, that one will then have priority |

It's usually nice to see the short period peaks on a sunny day during raining season

Re: Solar Energy, A Complement To FTA by pcoolioz(m): 1:49pm On Jul 20, 2020 |
Hello All, So I have a quick question. I am not so experienced with inverters and all so my question might be basic to some of you. From my research, I read deep cycle batteries get bad when you use below 50 percent of its power consistently and when you overcharge. I have a solar panel so my inverter is hardly ever dead or I hardly get to 50%, but how about overcharging? Does the solar panel constantly charging it everyday damage the battery still? The inverter is hybrid so it stops charging when the battery is full. So my problem is will the everyday usage affect it somehow? That is my question. |

ojeysky:this is nice 2314w out of 2520w panels. i cant wait to install mine soon. |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 3:12pm On Jul 20, 2020 |
Trippledots: PROs: At more than 20,000 cycles, the LTO chemistry has the longest life of all the Lithium batteries. It can be discharged to 0v without any serious consequence. Some manufactures actually ship them out at 0v state of charge. Some of mine were at 0v when I received them. LTO does not combust due to overcharge or any other abuse. There are a lot of LTO abuse videos on YouTube. It can be charged and discharged at a very high 'C" rate (10C or higher). You can fully charge a LTO battery in 6minutes if you have a capable charger. I have used mine for over two years now and I have not noticed any loss of capacity. If I consume 300Ah, it will require less than 301Ah to recharge. The cycle efficiency of mine is 99.9%. It does not heat up during charging of discharge. It stays at room temperature 24/7. As at today, LTO is the best battery money can buy. CONs: It is much more expensive than other Lithium brands It is heavy, So, it is not very suitable for mobile application 4 Likes 1 Share |
