AinsSama:If I may ask sir, what type of inverter is that? The dynamic dollar rate may still get you on the way, if you're not also buying other items on time Lol. |

AinsSama: This ur plan will end in premium tears. Bookmark this page Why and how did you arrive at the conclusion that u need 10kw inverter?? 1 Like |

earthrealm:quack installers, with moronic quotes is to be blamed sha. 10kva inverter on top 4pcs cheap fake capacity 250ah lead acid gel battery(actual capacity might be 150 to 180ah). if u calculate inverter idle current draw@ batteries 50% DOD, then battery might run down in 24hrs, without any load on inverter. with his load, he needs 5kw hybrid inverter 6000w of panels 28kwh lifepo4 lithium battery bank. thats approximately 7m budget. otherwise big premium tears is loading... 2 Likes |

E will b charging 2400w daily. If he's doing 50% dod. 800w is truly not enough considering the fact that other appliances will b on during sunlight. But if he's on a tight budget. That will do. isangjohnson: |

U will need to check d name plate of the freezer. But my guess is 130w. My 160l freezer is 109w Pumping machine is how many hp. I'm using 0.75hp n my 2.5kva displays 53% usage wen it's on. Wat kind of fan Check ur tvs back but Im guessing like 100w. Mine is 74 For the lightening.. u might decide to buy 5w bulbs if ur current type is consuming more Check ur laptop adapter for d wattage. If u can't figure it out. State d model. Wat kind of washing machine. Check d name plate. In my honest opinion. Ditch those lead acid batteries for lifepo4. U wont b spending up to 100k more for more power n durability n longevity. U won't b spending up to 1m even if u decide use lifepo4 with 1200w panels sef emmy9500: |

AinsSama: earthrealm Load will increase drastically by next year by 100%. It's more of a futuristic planning with limited budget for now. Current battery totals about 10kwhr. It's a temporary solution b4 an upgrade to LiFePo4 pack hopefully. Already saved your contact for that purpose. |

isangjohnson:It's a Solar inverter (not hybrid tho) |
Re: Solar Energy, A Complement To FTA by isangjohnson: 1:22pm On Nov 30, 2022 |
AinsSama:I don't really know how you'll get the needed help in this faceless forum, if you're not dropping complete information. Which one is solar inverter? I was actually asking for the name of the inverter you've already bought so we could know the next advice to give as the mistake has already been done. You may be testing public opinions here... Whatever is the case, this is a learning platform where most of us including myself came to seek help/advice often. I wish you all the best. 3 Likes |

emmy9500: The panels are insufficient I doubt the charge controller is suitable, especially for the type of batteries quoted. |
Re: Solar Energy, A Complement To FTA by Juror: 3:25pm On Nov 30, 2022 |
emmy9500: did the installer tell you that the setup would power these or you're the one assuming? Because your batteries are already dead, even before installation. 5 Likes |
Re: Solar Energy, A Complement To FTA by Juror: 3:31pm On Nov 30, 2022 |
AinsSama: With your batteries, you should be talking about minimum of eight panels, and you already said maximum of four? |
Re: Solar Energy, A Complement To FTA by Juror: 3:36pm On Nov 30, 2022 |
emmy9500:If you're really talking about durability, you may have to double the amount on the quote or increase the budget while taking off some load from the list for now, especially those machine - machine loads. |
Re: Solar Energy, A Complement To FTA by Juror: 3:40pm On Nov 30, 2022 |
AinsSama: If you have the money, I'm not sure these loads are actually for lead acid batteries, that's not saying lead acid won't work but you'll need lots of space and babysitting for DOD, balancing etc. |

Re: Solar Energy, A Complement To FTA by Juror: 3:56pm On Nov 30, 2022 |
Kabawhat:Separate inverter, charge controllers have their advantage over the all in one especially when there's a malfunction. If the all in one has a fault and is decommissioned for repairs, your batteries are alone till the repair is completed unlike if either the charge controller or the inverter in the standalone setup is faulty, there's still a charging source available. 1 Like |

A church member reached out to me to come check out their solar-inverter installation. The wife said the batteries don't last anymore and that the inverter spoilt and the guy that installed it initially took it out for repairs. My first thought was, well, let me recommebd a budget 24v inverter you could use then. It was a no-brainer. I reached out to Valto for current prices of his inverters and funds was about to be disbursed, but on a second thought, I decided to first work with the spare transformerless easun12v inverter I had. Besides, that should give me an idea on how weak the batteries actually were. So I separated both batteries and hooked them up individually to the 12v inverter and they observed how long each of them lasted on a fixed load. Expectedly, one was failing faster than the other. After that, I decided to combine them in a parallel 12v to see how long they would last together. Brethren, after the whole connection, inverter refused to come on. No sign of life at all in inverter. Confusion hold me...lol When the husband saw my confused state, he began to open up. He said that is the 4th inverter that is spoiling on the set up. He began to blame his wife for not supervising how the set up is used at home. That they put on even pumping machine on it and all. That the one at their school hasn't spoiled, etc etc. I doubted that overload was the cause of the damage, coz the inverter has overload protection. Then it occurred to me that someone here once had a similar issue and the possible identified culprit was the earthing connaction. So I asked the man if his earth connection was properly done, he then confessed that he doubted so. That there was a way the house was wired and all of that, and that he would call his electrician to inspect it. My point is, people/clients can so withold relevant information eh! Imagine if i had gotten a new inverter, and this issue happened. Probably, I would be dragging the seller by now. Sad situation. Please, how can this be resolved? Is earthing really the issue and what can we do? Also, what is likely to have spoilt in the inverter? I just weak...something wey I no even charge them, based on hobby and relationship waka, i now lost a precious inverter... 2 Likes |

emmy9500: In addition to the numerous sound advise you have gotten from experienced folks, get an MPPT solar charge controller. You are investing a lot to use that PWM your installer is recommending. Thankfully, I have a budget MPPT CC for 63k. https://www.nairaland.com/390522/solar-energy-complement-fta/1303#118683492 You can reach me via the contact in my signature Also, please avoid lead acid batteries. Stick with lithium batteries |

Greetings house. Please I need advice for what to get for a shop on low budget. Load is, 60 watts oscillating fan 40(4×10) watts bulbs 100 watts(not sure) tv Personal phone charging (5 pieces). All will be on for duration 8.00am to 7.00 pm daily. Will these items do the work? 100 watts panel 10a pwm charge controller 40ah lead acid battery 300a msw inverter. As an unrepentant DIYer, I am setting it up myself Thank you. PS: If I opt for li-on battery, it will be like how much for it? |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 6:17am On Dec 01, 2022 |
emmy9500: Better, you are now talking my language. If anyone wants to do solar, one basic thing is: how do I get it right! Ignoring this is a very big disaster on your part. Since you are using a 24 volts system. Kindly get a fangpusun 50a mppt or Epever 40a mppt(no 50a). Stay away from PWM, except u really know what you are doing. |

toyeoye:My brother, you think I am making jest of him? I was very angry with the post! Do you think that even with his stated budget, such money is easy to come by with the current state of Nigeria's economy? If u have a cut cost mentality in solar, u loose every penny spent in months. 1 Like |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 6:36am On Dec 01, 2022 |
AinsSama: With a 150v voc, do 3 in series. You can see that your 4panels in total is grossly inadequate! As pointed out by @earthrealm, all he mentioned are valid. 10kva has a lot standby consumption! I will do a minimum minimum of 9 of 350w panels. I prefer 12 minimum anyway. 4 batteries can never cut it. |

odimbannamdi: Also had tha t issue sometime ago, 2 inverters died within 6months, after the 2nd death i told owner to do a new earthing just for the inverter, as i suspected the shared earthing had voltage leakage....going to 6months now everything is working ok. consider doing this or dont hook up to earthing at all and observe 1 Like |

odimbannamdi: earthrealm: I complained about my hybrid recently It started misbehaving the moment I connected it to charge from grid. Since I removed that it has been okay. I'm suspecting earthing too because when it was connected the body was "shocking" odimbannamdi: Interested in this too. And the cost |
