ojesymsym: Check well. It says 10A at 250v. Good enough for a 1HP system. If something can handle a heater, I doubt it'll have a 2A maximum current rating. |
Re: Solar Energy, A Complement To FTA by ojesymsym: 4:57pm On Jun 18, 2020 |
Even though I consider 10A too small, but I do not understand the 10 and the 2 in the bracket in their description. mctfopt: |

garbamaza: I came across this home solar air conditioner, purely operated with solar panels without need for batteries. Gentle men, I need your suggestions about this product. Thank for your possible urgent responses. |

mctfopt: I think inverter ACs have a way of saving energy when the room temperature reaches the desired preset. That's one of the ways they are able to save energy. |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:24pm On Jun 18, 2020 |
ceaser: Not really, at least not the inverter ACs I've seen. They continue drawing some current even when the room is cold. |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:34pm On Jun 18, 2020 |
garbamaza: It looks like a grid tie system. Not really something you will want if you are solely off-grid as I see where it is stated it automatically switches over to mains if the solar generated is not enough ie during cloudy times and at night. But it looks like something designed to help reduce cost of electricity/reduce cost of diesel (from DG) in offices that operate during the day that has a generator at work. In my opinion I think you are better off getting a low power system run off batteries that you can use at all time. But it all depends on what you want to achieve with it considering you may be looking at a system that reduces cost of electricity during sunny days/ reduce cost of fuel during the day. |

Penuelseun: I agree entirely. My transfer is so fast that my TV and DSTV decoders don't realize that power source has changed. You can also add a manual control and indicator of your choice. Most importantly you can use a timer, or an esp wifi relay like sonoff basic to activate remote, manual and automatic control. The only problem I have is that the 2NO 2NC contactors I use are becoming scarce in the market. |

earthrealm:Wow... Truly I left the wire size unnoticed. Instead of going for another wire, I will prefer the 2S2P for now. I will provide feedback on the performance. Thank you very much. [/quote] I did as you stated and there is now a great improvement. But the Max input voltage is 70V. I don't know if it can handle the voltage from the array when the sun is at peak |

Re: Solar Energy, A Complement To FTA by bodeface: 11:11am On Jun 19, 2020 |
Please RE House,; Good morning! I am trying to upgrade my solar installation and I need advise from experienced members, installers and seller in house. I currently has 4 X 200Ah AGM battery, which have served very well, I am undecided on either going for 8 X 200Ah or I should port to Lithium Battery (LiFePO4) I know LiFePO4 is better in performance, you can derive more juice from it compare to AGM, I know all that stuff. But more on value for money, 1. Is these LiFePO4 reliable 2. What's the failure rate like, in AGM battery bank you can replace a failed single unit (though not advised) 3. What's user experience, any user experience? 4. What are good model / manufacturer to consider for value for money 5. What do you advise; buy the AGM or buy the LiFeP04 Thanks |
Re: Solar Energy, A Complement To FTA by spartacus11(m): 11:22am On Jun 19, 2020 |
bodeface: 1- very reliable 2- the failure rate is very unlikely, yeah even if any cell pack is bad u can replace it but most times all there need is for u to balance ur battery pack 3- there are user experience here but u can check some of my past posts as at last week to see some YouTube reviews 4- there are premium brands as well as brands that are not too know but stlll value for money 5- Buy lifepo4 , and have rest of mind without babysitting you battery bank, no worries of not having a full charge everyday, have more juices to use. Go for Lifepo4 please, More value for money 2 Likes |
Re: Solar Energy, A Complement To FTA by bodeface: 12:24pm On Jun 19, 2020 |
@spartacus11 Thanks for elaborate explanation and encouragement to go for LiFeP04. Can you kindly give examples for your point number 4 below? Appreciate more views from users 1- very reliable 2- the failure rate is very unlikely, yeah even if any cell pack is bad u can replace it but most times all there need is for u to balance ur battery pack 3- there are user experience here but u can check some of my past posts as at last week to see some YouTube reviews 4- there are premium brands as well as brands that are not too know but stlll value for money 5- Buy lifepo4 , and have rest of mind without babysitting you battery bank, no worries of not having a full charge everyday, have more juices to use.

Re: Solar Energy, A Complement To FTA by ceaser: 5:20pm On Jun 19, 2020 |
So I went shopping today hoping to get a low power consumption freezer, a bigger size actually cos I run a 203L (114 watts) already. I saw a thermocool 260L that has 110 watts on the nameplate. A similar looking one (same product and volume but different colour) has 104w slapped on the nameplate. I saw a double door Thermocool 300L with 130 watts, yet I saw another 300L double door Thermocool inverter with 140 watts on it. That's when I got confused. Two products (the same manufacturer and volume but one is inverter freezer and the other is not. But the inverter has higher watts (140 watts) than the regular one (130 watts). Sadly in all these, I forgot to take the wattmeter along. Biko, what is now inverter about the freezer if the watts is higher than that of the regular? Or am I missing something? Please o, anyone experienced should enlighten me. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 8:10pm On Jun 19, 2020 |
ceaser: i had the same challenge, back then JUO posted an LG inverter fridge, that he claimed consumed 30w, i traced the fridge, and found it, the energy nameplate on it is 110w abi 100w, got me confused. on LG website, the put 265kwh/yr as the annual consumption of the fridge, which if you divide by 365, you would get about 30w. the theory i think is that after working for some time, say 24hrs..i believe the energy consumption gradually drops to below 30w, Juo confirmed that his fridge records zero watts for some periods, so to enjoy these inverter appliances, i have deduced, its best they are powered 247, thats when you get the max energy savings... the haier inverter fridge, is it frost free? i am interested on this your fridge waka, pls keep us updated, jumia now has 13amps watt meter for 6500naira, incase you are in need of one 1 Like |
Re: Solar Energy, A Complement To FTA by ceaser: 8:33pm On Jun 19, 2020 |
earthrealm: Thanks for the explanation. earthrealm: I don't think the freezer is frost free cos it's written on it that it keeps things frozen up to 96 hours after power failure. I believe it's the frost that does that. Sadly, the shop I checked, that inverter freezer unit was the last on the shelf and already taken. The price was 320k. The non-inverter one is 300k. I would have gone for it if I didn't see/know that the inverter version exists. The shop was almost empty, covid things precluded restocking. Now I have to start scouting for inverter freezer all over the place My wattmeter still functions, but I only forgot to take it along. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 9:04pm On Jun 19, 2020 |
ceaser: on my 4 batt setup, since i installed the 280w x 6 panels, my 130w freezer has been on 247, and my battery bank is unfazed. however, i get phcn about 8 to 12 hrs daily. so am now certain my setup can conveniently handle a 130w freezer 247, and an inverter fridge 247 as well. or worst case.. i line up the ATS & timer switch on the freezer and leave the inverter fridge i intend to buy to run 247 i had excess energy today, and decided to power the sumo with my 4kva mustpower inverter, the sumo clocked in @ 74% load, making me suspect its a 2hp sumo, my dinrail watt meter and 13amp watt meter is inbound, so will have more accurate readings as well. kept a hawk like watch on the sun/incoming harvest, as i didnt want the strain of the sumo to get to the battery, as my harvest hovered around 1350w abt 1430hrs today solar is bae, i no go lie |
Re: Solar Energy, A Complement To FTA by ceaser: 9:38pm On Jun 19, 2020 |
earthrealm: You no lie. The mere fact that you have all that power free from nature is exhilarating. https://www.kitchenarena.in/inverter-refrigerator/ I came across this website that discussed how the inverter appliances work and went ahead to compare inverter frighe offerings from Samsung, LG and one intellisense manufacturer like that. Inverter frigdes are the bomb, your battery bank will not even do any work overnight with an inverter fridge. The website went further to explain that LG even has a still better offering with their use of "linear inverter compressors" which is further energy efficient than Samsung's inverter compressor. I'd have loved to change my search to LG inverter freezer but apparently LG is yet to have an inverter freezer for Nigeria, cos what I saw written boldly on the thermocool I saw today is: "Nigeria's first inverter freezer" 1 Like |

Kodartech: if i choose the k1000 payment plan, can i upgrade at a later date before the expiration of the 48 months? What happens after the 48 months? How much is the cost of installation? in Abeokuta? |
Re: Solar Energy, A Complement To FTA by essegis(m): 8:23am On Jun 20, 2020 |
Hello guys, Anyone got any idea of how I can bottom balance my LiFePO4 cells? I don't know what takes 3.2v and no equipment to use and transfer its charge into another set of batteries. Any idea is welcome though. Im sure sha if I check this house properly I will see my new box of resistors (though not the box type). And I don't know which exact amount to use to drain the bank appropriately. Any calculations for things like these? See bank below.

NiyiOmoIyunade: @NiyiOmoIyunade Thanks for your comment too. I intend to use option 3. I will also ensure equal cable length for the battery banks. @the bolded. Can you explain further or depict it with a rough diagram. For the bus bars, how thick do you think a a bus bar should be? Very thick or very light? Cheers.
