Give more details preferably specifications of ur inverter, solar panels and we might help diagnose what's wrong with ur setup. It might just be a little tweaking and you will get the output required. nonoski: 1 Like |

pranil: Ok Pranil, you were referring to LCOS rather than LCOE. LCOE by its definition should include the total cost of the PV system (panels, controllers, inverters, batteries etc). In your case, you would have to estimate the resale value of your old system to calculate LCOE. I would like to see any company that can provide a storage-based PV system at lower than N80/ kWh in Nigeria. 1 Like |

DMerciful:The Inverter is Exulted Inverter 3.5Kva; The Charging Current is 53.4v and the charging current is 11.4A The Solar Panels are also Exulted 300w rated (Voc 38.8v; Isc 10.21A) 12nr connected in 3S4P. For now i believe the problem is the Inverter and 1 or 2 bad batteries. I am making arrangements for Mustpower 5Kva Inveter then i change and increase my battery bank |

NiyiOmoIyunade:Please given ur experience which battery is best recommended for use with solar system. I have been using Bluegate Sealed VRLA batteries coz the distributor here in Port Harcourt is a registered Distributor of Bluegates Intl. But i dont mind testing another brand |
Re: Solar Energy, A Complement To FTA by sinistrian(m): 10:00am On Apr 18, 2018 |
nonoski: Yes, that charging current is pretty low for your bank. If you're buying the mustpower, bear in mind the idle power consumption: its about 100W. 3 Likes |
Re: Solar Energy, A Complement To FTA by nonoski: 10:23am On Apr 18, 2018 |

Please for those in Abuja and other north central States what is the the best time period for programmable timers for a fridge and a freezer? Any pointers would be appreciated |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 10:38am On Apr 18, 2018 |
Mine is 9am to 4pm. 8am to 5pm for northern states sounds about right... |
Re: Solar Energy, A Complement To FTA by Chuckdee(m): 10:53am On Apr 18, 2018 |
Barezzi: @ Barezzi, looking at your setup capacity from your signature, why are you still running your freezers on a timer?? I hv a much smaller array than yours and I found out that running the freezers on 24/7 consumes far less energy than turning it off and on intermittently. I used this cheap wifi plug to monitor consumption via an app over a period of time to come to that conclusion. give it a try. https://www.amazon.com/gp/product/B0178IC5ZY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 11:28am On Apr 18, 2018 |
@Chuckdee, Actually, I have 2 fridges and 2 freezers. The fridges are on inverter while the freezers cycle 9am to 4pm. I'll run both overnight for a couple of days and see how it impacts on the bottom line. I like to keep my night time consumption below 5 units. I'm currently reworking my set up, seems the life of tinkering will never end. 4 Likes |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 2:10pm On Apr 18, 2018 |
so i went to check out the lg 1hp inverter ac, i was not impressed by the specs written on it..even though it had a sticker screaming 70% savings in energy consumption, am still wonderin hos possible this is based on the energy nameplate. lg 1hp inverter ac cost 129k, normal 1hp ac = 104k naira normal consumption = 800w max consumption= 1200w, so where then is the energy savings??, would appreciate reall world figures from a current user |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 2:39pm On Apr 18, 2018 |
The 1hp rating is for the compressor only - other elements e.g blower fan e.t.c may consume additional power. On my 6 year old 1hp AC, it was common to see power draw up to and above 1kw. When I switched to the 1hp inverter AC, it draws about 1kw in normal mode (ramps up gradually from about 400watts so you don't get that surge effect) but when you activate Gen Mode, it goes as low as 500watts (again ramps down gradually). My current usage is to keep a constant temperature of 24°C and run 'Jet Mode' for 1 hour between 8 and 9pm for rapid cooling then 'Gen Mode' from 9pm to 7am in the morning earthrealm: 1 Like 1 Share |

NiyiOmoIyunade: so how is the cooling effect in gen mode??....lemme know if i will run it 24/7 on gen mode. does it still go as low as 20deg and high fan speed on gen mode?..trying to understand how it saves/uses less energy .24deg may only be effective for me at night, during the day 23/22 wud be preferred |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 6:56pm On Apr 18, 2018 |
The cooling effect of the inverter AC in Gen Mode is sufficient to be comfortable but does not have that chill-tang/frosty effect that normal AC has. After some hours, you can get the room temperature down to between 22 to 24°C depending on how hot it is outside. For now I am still watching and measuring the consumption. With what I have seen, I may swap out my 2hp sitting room AC for a 1hp standard AC and support it with a fan. Those 2hp units are bloody power hogs. earthrealm: |

earthrealm: Let me bring the house up to speed on my search for DC air-conditioner from Green Energy Innovation. Thanks to Pranil, for providing the much needed link. I sent a mail to the company and was linked up with their suppliers here in Nigeria(one in Lagos and the other in PH). The one in PH replied my mail while the Lagos one is yet to after 2weeks. Currently they don't have supplies but are awaiting some soon. The prices are: 1hp......$1,385 1.5hp....$1,695 For the unit only! Now Oga earthrealm, the performance is not bad ooh, after getting the prices above, my friend decided to buy the 1hp LG inverter AC and I was surprised by the performance....on a 24v-2kva system, it took 8hrs for the battery(200Ah x 2) to drop from 25v to 24v. Initially wanted him to go for daikin inverter AC but couldn't source locally |
Re: Solar Energy, A Complement To FTA by life707: 7:22pm On Apr 18, 2018 |
NiyiOmoIyunade: Good analysis. After feeling the cool of the LG inverter at work, I think the info from different people that the gen mode does not cool much is not exactly true but as you pointed out above, it may not be as icy and chilly like the Ac mode...but you will know that AC they blow you well in gen mode 1 Like |

Re: Solar Energy, A Complement To FTA by pranil(m): 8:04pm On Apr 18, 2018 |
earthrealm: The energy is saved by the variable speed compressor and higher efficiency gas and condensers. Normal Ac runs in ON off mode while inverter AC only draws power required to reach the cooling temp. This video from LG explains it better than word An additional benefit of inverter AC's is they can cool faster in jet /power mode as the compressor can go into overdrive Also, they are able to maintain exact setpoint . for my bedroom when I set 26 it is at 26 +- 0.1 https://www.youtube.com/watch?v=G0ueIUEojI0 https://www.youtube.com/watch?v=G-YtYp2RJ-k 2 Likes |

davodyguy: davodyguy, lolz! these are throw back pix of the early years in my journey to energy freedom. ah! the joys of the internet, a place where memories never die! for starters, that pwm cc in the first picture served its time well without issues. after being in the cooler for a couple of years, it is now producing much needed juice for a reputable medical doctor in benin. the 5kva prostar inverter in the second picture blew up without warning one fateful morning after working all night. i had earlier shut down it down to cool off in the morning and when i went back a few hours later to put it on i heard a loud bang and that was the end. the local dealer whom i bought it from wasn't too excited when i took it back to him for repairs, citing lack of available spares, support, etc. well, that shouldn't have come to me as a surprise - afterall, what do you expect from a chinese made mid-range product? ok, the batteries were zenith 200ah and lasted about 5yrs give and take. i was so impressed with their performance that i decided to replace them with their 260ah senior cousins which i'm using till date. as for the 5kva binatone stabilizer, i guess it just couldn't cope with the huge power draw from both the inverter and house loads that it caved in and went into early retirement... i could go on but that would mean writing a whole book on my long journey into renewables... |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 8:49pm On Apr 18, 2018 |
I do not know this exulted brand however you did not mention what charge controller you are using. Mustpower idle power consumption is appreciable and this increases with the kva so be mindful of that. your panels is enuf to charge ur batteries and at least augment the inverter gap.....you might need to check if the panels are facing the right angle nonoski: |

Bug kudos to you, cos you started going Green and clean as far back as 8 years ago. Some of us only started recently and we hope many more Nigerians embrace the clean energy. I'm having issues with some of my neighbors now. Ask me why? They have a very terrible noisy generator. I've preached Inverter and solar, these fools claimed no money, but one of them recently bought a car worth 1.2million just to prove a point, cos they can't stand the fact that my wife uses SUV, hence the wife too needed to show off. That's how terrible mentalities of people are. They run this gen whenever there's no mains power supply for almost 12hours in a 24 hours day, with the noise disturbing the neighborhood. In July, 2017 their 1kva Tiger generator caught fire, but luckily for us, it happened around 8:30pm. I used two of my cars' fire extinguishers to help them prevent disaster. Thinking buying PMS to fuel gen daily is a sign of being rich is a stupid as a butterfly trying to fly as high as a bird. I'm sorry I have to express myself to this extent, but that's how Nigerians are. May God help us GeorgeD1: 3 Likes |
