EPOMA: Depending on how they sense voltage, one will always perform slightly poorer than the other. Battery voltage is a major determinant of how charge controllers work. Once two or more charge controllers are giving conflicting voltages, however slight, one or more will overestimate the state of charge of the battery and slow down. Even the parallel configurations don't change the outcome much. I once wasted money on another Outback charge controller because I thought it will work better with the one I was then using. All you can do is to ensure that the set voltages are the same, use same wire size and length from the controllers to the battery and stop worrying about the differences you will note, usually towards the end of the day or when your battery is full. 1 Like |

NiyiOmoIyunade: True, I was using a 24V system at the time. Never realised that system voltage had a role to play in what was a major calamity. |

zeestone99: I had a sad experience with the Morningstar MPPT Charge Controller. Two got destroyed in my early solar years because of battery disconnect issue. I swore for them since then. They appear to be the only one with that problem since I never had that issue with any other charge controller. 1 Like |

desiji: By the way, this is not the MPPT board, this is the inverter control board. What happened to it? Was the inverter struck by lightning? 1 Like |

desiji: I'm not going to get into silly name calling with you. That will be beneath me. A boy of 19 is a man. He is a qualified installer. Maybe you think that people need to be 100 before they can become an installer. By the way, how did you know his age? Yes, you apparently wanted to scam me. Thank God I sent someone who knew what to do. Please deny any of these facts. 1. You advertised the inverter for sale. No indication that anything was wrong with it. 2. I dropped my number and asked you to contact me. 3. You called me to negotiate the sale. We negotiated 450k. 4. During the call and several other calls thereafter, you never mentioned that anything was wrong with the inverter. 5. You actually told me that you used it only for about a month. 6. I asked you to tell me when you will be available. You said from Tuesday. 7. On Tuesday morning, I called you to confirm if you are available. You said yes. 8. Just before the guy set out I called you to ask for the address. You gave it to me. 9. At no time during all these interactions did you mention that the inverter was not working. 10. It was only when the guy asked to test the inverter that you started telling him stories. 11. When he called to tell me, I called you back to confirm and you said you needed to replace one board and fix the display. You then asked if I wanted all these fixed and that you will not take 450k anymore, but 500k once you fixed it up. 12. Having seen that you are not reliable, I asked the guy to leave the place immediately. I was even scared you may harm him. I waited until he was on his way back to Ibadan before I shared my experience here. Finally, I shared my experience simply to warn others who may make the same mistake I almost made. I thought that you are a honest person and you posed no threat of fraud. I was going to send my younger brother with no knowledge of inverter to come and pick it up. I suspect that you would have just packed the damaged inverter for him to bring for me. I will refrain from responding to other needless comments you made. You clearly intended to dupe me, otherwise, you had many opportunities to come clean about the state of the inverter. If you had intended to repair it before giving it to me, you wouldn't have allowed me to send someone from Ibadan only to start telling him stories. You wouldn't have also changed the price when you offered to repair it. I hope that I have created enough awareness for anyone hoping to buy this or any other thing from you; they must shine their eyes. 21 Likes 1 Share |

desiji: Anyone trying to buy this from this guy should be careful and do their due diligence. I just wasted 10K trying to buy it only to realise that the inverter is not functioning and will need to be repaired. I contacted the guy and we agreed on a price. I then sent an installer to go and test the inverter and bring it back to Ibadan for me. That is when the story changed. It was a good thing that I sent an installer who asked for a test, a different person could have brought a non-functional inverter back home for 450K. People who are part of this fraternity need to be upfront about the condition of whatever they are selling, otherwise it will look like a scam. 16 Likes |

BIAFRONIGERIAN: Your leaders who stupidly took you into an unwinnable war and still refused to surrender when they started losing big were responsible for this. Leave the Queen out of it. And I hope you will not let Nnamdi Kanu and his fellow miscreants lead you into another one. 3 Likes 1 Share |

ojeysky: But, if you ever plan to grow your setup, it is better to do 48V. I started out with 24V thinking about the cost of battery. I ended up moving to 48V when I scaled up, but I was stuck with a high-end 24V inverter that I couldn't dispose at a good rate. 2 Likes |

TechGeek777: Yes, I have some SPDs. The SPDs don't give you 100% assurance. I believe that my charge controllers and other things were protected by the SPDs. |

toyeoye: Inverter is often the most catastrophic failure point. Once it goes down, you are in the dark. My trick is to always have a spare inverter. About 2 months ago, I was to travel to Abuja and night before the day of my flight, my inverter packed up. A thunderstrike took out the inverter. I had to set up the spare that night or my people will have no reliable electricity till I return. So, have a backup inverter if your system is critical to you. 3 Likes |

samnaija: I will personally not recommend microinverters for several reasons. 1. Cost. It is likely to be more expensive as each panel will have its own inverter. If you add more panels you need to buy more microinverters. 2. You end up with more failure points. 3. It is more technically involving and I doubt that our local installers have experience with it. 4 Likes |

AndroBlaze: The most important thing to take out of this needless argument is that anyone who has the means should go for Lithium from the world go. LA has unfortunately become an expensive lottery, especially with the low quality Indian and Chinese imports. 3 Likes |

NiyiOmoIyunade: Bolded is not true bro. With 100A out of 100AH AGM, your voltage will sag so crazily that your inverter will shut down. One reason why people can take large amp out of even a small lithium battery is that lithium maintains a good voltage until almost the ![]() 100A out of 100AH AGM will probably last you about 5 minutes before you voltage becomes too low to sustain your inverter!

pcoolioz: An interesting situation. Use a meter to determine the true voltage of your battery. If your inverter is the one displaying wrong voltage, check the battery terminal on the inverter and be sure it is properly tightened. If that did not work, check if your inverter has a voltage calibration menu and adjust as necessary. If none of this works, your inverter may need repairs. 1 Like |

samnaija: Actually, this question of 5 years is a fake question. You are asking knowing fully well that Lithium for solar became practicable/affordable only about 3 or so years ago, especially in Nigeria. However, if you are asking for experience with lithium batteries in general, then the answer is yes, even you are likely to have used lithium battery for more than 5 years. 4 Likes |

GeorgeD1: At this time, lithium battery will still be at about 53V at least. One thing people don't fully appreciate in lithium chemistry is the improved charging efficiency. Lithium charging efficiency can be as high as 95% or more compared to about 80/85% for lead acid. So, you waste less solar power to charge your lithium batteries and on poor solar days you fill your battery more quickly. Lithium is just superior to lead acid in every way, people saying otherwise are just being purely dishonest or poorly informed. 11 Likes |

When all the people defending lead acid battery start using lithium, they will have an epiphany and change their minds. I have never sold a single ah of lithium or lead acid battery, but I have used Gel, AGM and flooded lead acid battery and they can not be compared to lithium. Taste lithium an experience the difference. 4 Likes |

Buy your car from local car lots and avoid these crazy stories. Except in rare circumstances, it always ends up being more expensive to buy from abroadians. 5 Likes |
