fikfik: HI everyone, ok thanks @earthrealm. I figured since I now have 24 hr electricity, I'm paying PHCN for storing the electricity. So, in essence, I'm paying as if NEPA never cuts power... Still much cheaper than the costs and hassle of buying fuel and maintaining the generator (by the way, sold it 2 weeks back)..... Next step, generating my own power. But i'm still at a rented house. Does it make sense to get solar panels on my landlords roof, for me to detach them when I move into my own house? any thoughts would be welcome. Is everybody with solar panels here, doing it in your own houses? |

Most of us i think still live in rented apartment. Enjoy ur life while you are still living. Go install ur panels. What do members think about the relationship between the solar array vmp and the system voltage for max use of mppt controller. I read somewhere that d higher the difference the better. The manual of my morning star mppt states a difference of 2v is where the controller operates at d highest efficiency. Your views pls. Attention: oga george. |

Are 48V inverters better than 24V, reasons pls. What do you think about BLUEGATE inverters. I saw a 3.5KVA and 7.5KVA all 24V inverters and i fell in love with them. 1 Like |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 7:00pm On Jun 27, 2013 |
fikfik: fikfik, you are very correct. when you install a back up system {inverter and batteries} you essentially store energy for future use. what puts that energy there? phcn power of course. remember that energy can neither be created nor destroyed it is only transferred from one form to the other. what you lose in terms of credit, you gain in terms of stand by power. so while your neighbors are busy suffering themselves with noisy generators during a power blackout, you are sitting cool in your living room enjoying back up power. is it expensive? yes in terms of initial cost of installation. but no in terms of convenience, health benefits and cost savings over time. you can install solar panels even in a rented apartment. all you have to do is to be a little bit innovative. you can install them on a small shed in front of your flat or you can mount a pole and fix them on top. if you can fix an ordinary binatone antenna besides your flat, mounting solar panels should not be that much of a problem. however, i'm not sure many landlords will allow you to install on the roof of their houses. |

abunafiu: Most of us i think still live in rented apartment. Enjoy ur life while you are still living. Go install ur panels. abunifiu, as earlier discussed, each solar charge controller operates optimally at different array and system voltages. for the morningstar depending on whether you are using a 24v, 36v or 48v system, your controller will be most efficient at different array voltages. therefore it is always advisable to study the oem manual of whatever charge controller you are using. a short while ago i went along with the theory that the higher your array voltage, the better the down conversion efficiency of your controller. so i changed my array setup to 3 by 3 instead of the usual 2 by 2 which i started with. i expected to see a significant boost in array performance which never materialized. instead what i experienced was a sharp drop in performance. i was losing badly needed power everyday on my back facing strings which i used for the experiment. recently i was forced to revert back to my traditional 2 by 2 setup and instantly i noticed that my array performance bounced back to what it used to be. therefore my advice to everyone is to study your charge controller manual and also confirm your module voltage at maximum power. arrange your panel strings in such a way as to get a near match of voltage to what your oem manual says. anything outside this and you will be losing much needed power by going for the 3 by 3 string arrangement in spite of the fact that you are using an mppt controller. |

blink182: How are the panels fixed to the roof, won't the roof leak with time? blink, i use a bracket which i fabricated through a local welder here. as for the roof leaking, you can always overcome that by using flashing during installation. |

Thanks. obijack, you are posting in the wrong thread. however, for w3a you can still use 12728h 30000sr {mta international}. you can also use 11192h 3210sr {mbc rodriguez}. intelsat 7ku use 12562h 26657sr {mesiah tv} or 12522h 26657sr {mytv} by the way those satellites have since changed their name. the one formerly referred to as w3a is now eutelsat 7a while intelsat 7 has since been replaced by intelsat 20. hope this helps? |

abunafiu: Are 48V inverters better than 24V, reasons pls. hello abunafiu, each inverter system voltage have their uses but if you want maximum efficiency, go for the the higher voltages. as for bluegate inverters unfortunately they are not known to be that efficient. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 7:51pm On Jun 27, 2013 |
all, last weekend, i carried out a stress test on my system and i ran it for about 4 days off grid. i have since combined both front facing and back facing panels and returned to the 2 by 2 configuration i can say the results are pretty amazing. pix below.

Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 7:56pm On Jun 27, 2013 |
looks like i need to change back to my back and front module configuration. presently maxing out at 3225w, a single charge controller may not be able to handle all this power going forward.

Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 8:00pm On Jun 27, 2013 |
monitoring still in progress.

Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 10:16am On Jun 28, 2013 |
abunafiu: hello abunafiu, i earlier on reverted to a single charge controller setup by combining all my arrays (back facing strings and front facing strings) into one. with this over-current alarm i'm presently facing i think it will be wise to split back the array into two like i earlier did and re-commission the second charge controller in order to handle the extra power coming from the modules. this i will do over the weekend - and with pictures as usual. 1 Like |
Re: Solar Energy, A Complement To FTA by fikfik: 5:19am On Jul 02, 2013 |
George_D: uncle george, please remind me, how many batteries (and in what array) you have to mac your 60amp MPPT controller? What is the wattage and spec of your panels? How many panels you sugegst for a 48V 200Amp (8 nos) battery array? Thanks. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 3:03pm On Jul 02, 2013 |
Friends, i am porting... and 1.5KVA 24V inverter and 2 solar charge controllers (30A and 20A)both 12/24V working range will be up for sale. I will definitely share the pictures of my new bride with you all after the ceremonies... |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 6:09pm On Jul 02, 2013 |
fikfik: fikfik, i have 12 pcs of 260ah batteries in total. my panels are all 200w each. for 8 batteries you can start with 4 pcs of 200w panels and increase from there. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 6:25pm On Jul 07, 2013 |
Oga George, two quick questions; 1. Do you use any battery equalizer in your battery bank? 2. Looks like the Sukam 3.5Kva inverter is buy and use, i was thinking it could be possible to set some few parameters in it like maybe charging voltage. Is there any connection possible with it for setup? |
Re: Solar Energy, A Complement To FTA by abunafiu(m): 8:13pm On Jul 07, 2013 |
bodejohn: Oga George, two quick questions; Am answering u in d interim sir, my oga george may be busy. Q1. No battery equalizer is used by oga george. Q2. You have to re-phrase ur question- But if i get u right, No user defined settings available on sukham 3.5KVA, however, charging current may be adjusted between high and low; with the aid of a switch situated behind the inverter(on 1.5KVA which am familiar with). I believe the same goes for 3.5KVA. I hope this helps. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 8:34pm On Jul 07, 2013 |
abunafiu: Thanks... My porting things almost completed... Sukam 3.5Kva...delivered!!! Legrand modular distribution module...delivered!!! DC circuit breakers...delivered!!! 2pcs of 50A 12/24/48V charge controller...to be delivered tomorrow!!! |
Re: Solar Energy, A Complement To FTA by abunafiu(m): 9:07pm On Jul 07, 2013 |
bodejohn: ure welcome boss. Abeg which one be Legrand modular............. And is ur charge controller MpPT? Whats d make. What PV module parameters and how many do u intend using.How do u in tend wiring 2 achieve ur nominal voltage of 48V. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 10:04pm On Jul 07, 2013 |
abunafiu: My battery and pv panels remains the same but I am changing my inverter and charge controllers. About the Legrand...see the picture in the link below. http://uk.rs-online.com/web/p/distribution-blocks/6203643/ It can be used to connect multiple battery banks and charge controllers instead of twisting the cables together or having several cqbles in one terminal. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 8:44pm On Jul 08, 2013 |
bodejohn, congrats on the arrival of your sukam inverter and dc breakers. just like abunafiu earlier told you and which you must have already discovered (since you already have the inverter with you), there are no user adjustable switches for changing charging current save the toggle switch at the back of the inverter. you can select between 16a and 12a charging current. of course you'll normally like to leave it at the higher selection which is 16a. also you get to choose between ups and wide ups. its is advisable to leave the switch at ups position. other than the above, the sukam inverter is really a 'buy and use' type of inverter. and that is another thing that differentiates it from others like cyberpower. you don't need any expert installer neither do you need to modify your house neutral wiring. as long as you have a basic knowledge of dc voltage, you should be able to get it up and running in less than an hour including battery connection. no, i don't have a battery equalizer. i use my tristar charge controller for that. |
Re: Solar Energy, A Complement To FTA by bodejohn(m): 6:02pm On Jul 09, 2013 |
Oga George, respect for the boss, Thanks. I saw the advert of the Sukam 48V battery equalizers and i decided to ask. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 8:17pm On Jul 09, 2013 |
bodejohn, sukam is a good inverter but don't fall for that marketing gimmick. unless you're using flooded lead-acid (wet cell) batteries you don't really need any battery equaliser. however should you need to equalise your batteries at any point in time you could always do it through your solar charge controller - provided you are using a high end brand with embedded features like the tristar mppt. |
