Please who has installed and used SunPower panels or has any experience with them? How well do they live up to their Tier1 panel claims? I am being offered 3.6kw of these at a juicy discount compared to my beloved Canadian Solar, if they are able to give me equivalent performance as my Canadian Solar array then it would be a very good deal indeed. I am about to take my 11kw array to ~15kw (end goal) and need to choose ![]() |
Re: Solar Energy, A Complement To FTA by Saipro(m): 11:03am On Apr 14, 2019 |
NiyiOmoIyunade:Bros, I'm unable to optimally utilise my 3kW. So efficient are my home devices that I run 2 freezers, a fridge and opportunistic loads (water pump, water heater, washing machine and some others) without crossing the 8kW utilisation on most days. Even with the occasional AC use, I rarely cross 10kW. What on earth do you plan to be doing with a 15kW array?! It also implies you'd have a battery bank of perhaps 48V 1,000AH. Or more. That's a small factory sir. 7 Likes |

Stay safe guys ! Protect your investment. The block terminal is rated for 250A; the fuse is just a 100A Yet the block gave way before the fuse; ![]() ![]() 1 Like

makavele: wow, what caused the damage, short circuit i bet, how did it happen |
Re: Solar Energy, A Complement To FTA by makavele: 1:27pm On Apr 14, 2019 |
earthrealm: This is what happened. Whilst in use like every other night, the inverter tripped and it was lights-out in the whole house. Went back to the inverter, everything was fine. Flicked the red switch off and on again, the inverter booted up and next thing I heard was " a loud pop and a spark" Then lights-out again. That was it. So I wonder where and how "any short circuit" happened; unless some village people have been doing things downstairs while I was up. |

Perhaps the fuse blade was not properly secured to the fuse block and partial contact caused the metal to heat up. You are lucky you weren't using this fuseblock and fuse with your MorningStar CC - imagine the block terminal heating up and giving way in the middle of a sunny day with the MorningStar putting out like 55amps - my oga na blow the MS CC go blow o with replacement cost of at least 200k ![]() This is why I use only manual disconnects between my MS CC and battery and 35mm cables too - I do not want a repeat of my unfortunate experience way back. If you must use a breaker or fuse, may I suggest you use a Chint DZ158-125 MCB - it is rated 100A and I have never known it to nuisance trip or fail in several applications I have used it in. It is also low cost (under 10k). Tomzn 100A breakers also do pretty well. makavele: |

Reprobate: If It the item listed above and you are using 1pc of 200Ah 12V battery. 250W is required if using mppt which is not need for this budget friendly option. Get 150W 3pcs(parallel them, use 12V controller 30Amps) use quality gauged flex cable depending on the distance from. Panel to battery) . We sell too most of the components but your discretion. |
Re: Solar Energy, A Complement To FTA by makavele: 2:49pm On Apr 15, 2019 |
pranil: Yes, I am thinking along this line too. The connections were torqued to the maximum permissible on installation. I guess we need to check and retighten all connections after every other month or so |

starpower: thanks, though I am looking at mppt cos of possible future expansion. 2ndly my solar mentor says he gets about 1200w avg from his 1500w panel, so extrapolating, I feel I shud be getting about 350w or 400w avg from the 2 x 250w panel = about 30amps at 12v, using mppt, so with 5hrs of sunlight, am fairly certain of the battery going into float daily 2 Likes |

Saipro: I keep hearing about all these "properly" built lead acid batteries, but it seems the ones available in Nigeria do not fall into that category. Check out this capacity test below. Two lead acids were drawn down and could not provide the same capacity on the next cycle as it did on it's initial cycle. https://www.youtube.com/watch?v=tM0Ot9HCCzc |
Re: Solar Energy, A Complement To FTA by NoMoreTrolling: 11:40pm On Apr 15, 2019 |
starpower: lol, bro no be just me buy am oo, na our family. anyway sha, it's about $999 for one, but they claim 3,000-5000 cycles, after which the batteries should still retain about 80% of their initial capacity. I think it works out, cause I've never been able to get more than 200 "TRUE" cycles from our lead acid batteries so far. After about a 100 cycles, our typical 200ah lead acids become say about 70ah and they just keep degrading. Well at least the ones that I've used so far. I can't speak for the expensive lead acids made by Trojan and other top companies. So if we can do some math here: Say I buy a cheap naija 12v 100Ah battery for 50k. I get a useable capacity of about 50ah and a cycle life of 100 so over the life of the battery, we would have 50ah x 100 = 5000ah. For the lithium, we get a useable capacity of about 80ah, or 100ah in my case and a cycle life of 3000 at minimum. so over the life of the battery, we would have 100ah x 3000 = 300000ah. Price of lithium Battery: N360,000 Price of Cheap AGM: N50,000 Amphour life of Lithium Battery: 300,000AH Amphour life of Cheap AGM: 5,000AH Hence, it would take (300,000/5,000) cheap agm batteries, that is, 60 cheap AGM batteries to make up for the one Lithium battery. 60 X N50,000 (cost of cheap AGM) = N3,000,000 Cost of Single Lithium battery = N360,000 1 Like |

Thank you my Oga. The NairaLand antispam bot apparently does not care about quality of posts or track record ![]() What I posted that got deleted was that Makavele's issue with burnt out fuse block/holder was probably due to partial contact at the terminals and he might consider a large DC rated breaker (Chint DZ 158-125 rated 100A or similar TOMZN DC MCB) as an alternative. Essentially thesame thing Oga Pranil later reinforced. I added as well that this random failure is the reason I use only manual disconnects and thick cable gauges with my MorningStar CCs - a fuse holder giving way on a sunny day with the CC putting out 55a could be calamitious indeed! duwdu: |

viazi: hello viazi, sorry I'm just seeing your post. I've been unavoidably busy. my zenith agm batteries are 6yrs already and still counting and from their current stellar performance they would easily cross the magical 7yr mark come september. like I said in an earlier post, solar power isn't rocket science: know the basics and apply the principles and you'll keep smiling while others continue battling with self-inflicted issues born out of ignorance. that said, I'll be happy to meet with your friend one on one and discuss. send me a pm through nl and i'll avail you my contact details. 1 Like |

duwdu: The freight forwarder handles clearing and all that hassle They had to be shipped by sea, as they were declared "Hazardous Goods". Not sure about the shipping cost, my sis in the U.S handled that. I asked her for the info, but she is having a hard time retrieving it. If I can get the exact figure, I'll let you know. |

Super excited to begin this installation. For anyone that is going to go this route, please ensure that if you connect smart batteries to inverters larger than 4kw, that you have a current limiter in series with the battery, to protect the internal BMS, from the large current spike that comes from the large capacitance of a large inverter. More information to follow this weekend.

GeorgeD1: Wow, 6 years on an AGM battery? That is uber impressive!! Honestly, with batteries in Naija, solar can sometimes feel like Rocket Science, lol. The last batteries we got (from JiJi) were babied and put through a C0.1 discharge, but still couldn't get past about a 100 cycles before they began massive degradation. All this while not going past the so called 50% limit on lead acids and fully going through a complete three stage charging regimen every time they were recharged. So what is your secret with your AGMs? Is your discharge lower than C0.1? Did you oversize your bank? Are you sure that you still have the same capacity you did as day one? or have they degraded, but still possess enough capacity for your needs? btw, how is your solar system doing? Last time I read your posts, you were generating upwards of 25kwh per day which just blows my f**king mind. |
