mjay:depends on the starting and rated load of your freezer. My freezer is about 150w on running. Load. Starting load is about x 5 of that. Once it's kicking the running load reduces to 120w or there about. |

Barezzi: If you use invert AC ( daikin and LG sell such models in Nigeria) you can easily run ac on normal 3.5 KVA inverter with 10 KWH battery bank. I run two such AC's on my 2 x 200 Ah x 4 battery bank with 2 KWP panels on 5 KVA inverter without ever reaching 50 % DOD .\The AC's have a power saver mode wihc take as low as as 300 watt in the night 1 Like |

guys i have reading people comments about effiency and all that. and am wondering well am in lagos the rains the cloudy wheather as been affecting my harvest. abi na my system get fault. becos nobody really talking about the reduced sunshine and reduced charging of system |
Re: Solar Energy, A Complement To FTA by samnaija: 4:16pm On May 29, 2016 |
reason i am asking is during this cloudy and rainy period. can someone add wind energy to the solar system to augment the low power from the sun . if so where can one get wind turbines in lagos because it is very windy . |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 4:39pm On May 29, 2016 |
U can order from aliexpress....cost is about 100k for 400w minus shipping samnaija: |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 5:58pm On May 29, 2016 |
samnaija: i think ur system is improperly sized. a good setup has 3 to 5 days redundancy built into the batt bank. i would prefer that to messing with and installing a wind turbine. |
Re: Solar Energy, A Complement To FTA by samnaija: 6:36pm On May 29, 2016 |
earthrealm: a lot of people on this forum always say the exact thing u stated. you cant tell me if your system carries daily a fridge, tv ,washing machine etc . not changing your daily pattern of consumption of energy as if it is a bright sunny day as usual. you will still have 3-5 days redundancy.. i would so much like to be enlightened on such a system. i taught you reduce your load especially if 3 -4 days consectively bad wheather and no nepa. |
Re: Solar Energy, A Complement To FTA by RipVanWink: 7:26pm On May 29, 2016 |
samnaija: yeah, cost is a big determinant of not building in 3 to 5 days redundancy as required, i hv a 24v 200ah batt bank in the villa, due to cost...i only hv half day redundancy .... only way i instructed them to stretch the run time of inverter on rainy days is to turn off the fridge/tv/fan....n use only lights.... in naija its difficult to have 4days non stop of badweather/continous rain...........even on cloudy days..the panels generate small power still energy is finite, cant be created from nothing, apart from turning off heavy loads, there is no way to increase ur runtime...unless u want to invest in a device called sunforce...this monitors the irridance and lets u programme the load attached to it to run on sunny days/periods etc........ some high tech inverters might hv this as a built in function. |

What is the best direction to face the solar panels. I mean, is it East or west. Thanks |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 9:36pm On May 29, 2016 |
Slightly south or if its not installed on the roof and easily assessible make it flat. We are about 7.5 degrees towards d north however the sun moves from 23degrees south to 23degrees north on a biannual basis. bisi12004: |

JUO: Lol. True ignorance is expensive. I guess you're next in line to be schooled as your friend has now admitted that he never claimed that MPPT charge controller can add power to what is sent out from the solar panels. Please be more open as him to admit the truth whenever you realise your mistake, that's if you will. 1 Like |

bodejohn: Dear TriStar tracking is in milliseconds and will not for once show in any log. |
Re: Solar Energy, A Complement To FTA by mank1234(m): 9:58pm On May 29, 2016 |
bodejohn: If you're saying that what u see at the input of the controller is not what comes from the panel, it therefore means that the reading at the controller is wrong, which is shouldn't be the case. I maintain that cc does not add to the power from the panel, it only ensure that the panel operates at a voltage/current combination that will guarantee maximum power and in so doing it uses little energy from the panel itself. |
Re: Solar Energy, A Complement To FTA by mank1234(m): 10:05pm On May 29, 2016 |
samnaija: You'll need a separate controller for the wind setup (not MPPT controller). You can't combine both solar and wind on same charge controller. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 11:00pm On May 29, 2016 |
mank1234: The reading at the controller is not wrong, just as the reading of about 200 or 300 watts shown by the CC on absorption is not wrong until you kick in a power load and the production jumps to about 500watts or more as the case maybe. The work of your controller is to optimize the power delivery to your batteries. Ok...assuming my controller is misfiring....how do you explain the later part of the day on the log when power output falls below the power input? Are you saying the controller corrects itself in the afternoon only to misfire the following morning? I will log one of the controllers again tomorrow and will upload for you to analyse. If you have a similar controller I will encourage you to log yours and share the file. |
Re: Solar Energy, A Complement To FTA by mank1234(m): 11:15pm On May 29, 2016 |
bodejohn:Very correct. It shows the power from the panel that's in use I didn't say your controller is misfiring but rather that the values are inaccurate. Power output shouldn't be more than the input Uploading your log does not change the fundamental thing stated above: log figures is inaccurate so long as output power is greater than input Power. I'm done on this. No more response from me cos it's obvious that we'll only be going back and forth without any success nor agreement. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 12:16am On May 30, 2016 |
mank1234: I am also not interested in the long dialogue since you or any other person has not uploaded another log to proof that the one I uploaded is incorrect or inaccurate. You also obviously overlooked the part of the log where the output becomes less than the input. I suppose the controller chooses when to work accurately and when not to. 4 Likes |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 2:31am On May 30, 2016 |
samnaija:rather than do that, why not invest in more panels? Nigeria is not in the path that makes wind energy very lucrative atm. Your turbines would need to be very high up and it's might lead to voltage loss or high cost of wire and mount. Unless u live in a sky scraper. |

Re: Solar Energy, A Complement To FTA by DMerciful(m): 6:00am On May 30, 2016 |
You were patient with him...you tried. I was through with him when he started arguing about fundamental physics. I use epever and when I read the voltage readings from the panel view and using a digital multimeter, I get different readings. There is a forum where someone even complained that the readings esp the SOC is inaccurate and wrote to epsolar, they told me to ignore the reading that it depends on several factors including temperature sensor. But what baffles me is how someone could argue about fundamental efficiency equation just to appear right! mank1234: |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 6:44am On May 30, 2016 |
DMerciful: Truly so. The meter supplied with Epsolar can't always be relied on. This is why I plan to install inline meters at different points of my installation. One between PV and CC to give me reading of what is coming directly from PV. One between cc and batter to give me figures on what is going to battery. And one between battery and Inverter to monitor what goes into and comes out of the battery. This would be a better way to have situation report and status of an installation. 1 Like |
