Barezzi: The setup looks enviable. Few thoughts 1. The battery is too small for 4.6 KVA load unless that is your peak load for bedroom /lights - 400 AH is hardly 10 KWH at 50 % DOD at 3 KW it is not even 3 hours of runtime in the night . I have exat seame battery size and I can run 800 watts for one whole night ( which includes 300-500 Watt of bedroom AC) 2. You might want to consider running the inverter in hybrid solar mode during daytime to maximize that 6 KWp Solar panels solar production . In that case I suggest to use changeover along with DOD cut off to keep non essential loads connected to grid if available on days when solar production is not enough otheriwse one angr better half 3. You might consider reducing the solar panel size and investing that amount in energy efficiency ( long term effects will be similar) specially as NEPA bill also comes down. Solar prices will always drop for next few years and you can always add more 1.5 KW diakin or LG AC is around 200,000 NGN but can run on as low as 300-600 WATT. LED bulbs ( i found the Yellights and Philips both reliable )- The yeelights are specially good at less than 20 USD in addition allow dimming and color change from you rsmartphone - http://www.gearbest.com/smart-lighting/pp_361555.html

pranil:To clarify, my house will be divided into 4: Panel #1 will carry ALL the light points in the house and circuitry in the Master bedroom. (~400watts @ night with aircon , 100watts without) Panel #2 will carry the kitchen, wholehouse fans, and Main lounge (~400watts @ night) This panel will drop off once the battery SOC gets to 70% due to grid failure or cloudy days. Both panels above will not exceed 4.6kva. Panel #3 will carry 13A sockets in the rest of the house and 15A sockets in the laundry room/water pump. This panel will get bi-directional feed from the inverter during the day. Panel #4 will carry the remaining 15A loads in the house, and will be supplied directly from PHCN. I plan to concatenate panels 1 to 3 in a single 3-phase panel, while panel 4 will be stand alone. I also plan to upgrade me banks to at least 500Ah. My goal is to keep nighttime backup load demand to 500w. I've got me sights on LG inverter aircon pranil: See comments above pranil: I love automation and control, and i'm looking at integrating the above using zwave via homeseer hs3.

interested in home automation too. any practical experience to learn from here?. Its been a while since I discussed my personal home set up. I recently hit 3kw pv strength. my 2 yrs old trojans still firing like new. I have switched charge controllers from morning star to FM80 and now midnite classic. I now live off grid and hardly drain my bank below 49.5v(with load) by 6.30am when I wake up. I now switxh off my 4kw mustpower(1.5 years old) inverter off when leaving home for work. once I return home ,I go tru d logged data. my batts reaches absorption usually by 1pm. 3 Likes |

abunafiu: I Have personally tried following air conditioner controllers for automation and love the ambilight followed by broadlink followed by Tado - too lazy to put links but google it they are easily found. On the lights I primary use philips hue with logitech harmony and amazon alexa works wonderfull. Personally I found zwave too much headache. My samsung smartthings is far from smart and constantly looses connectivity with my projector screen controller and it's own socket too many variables in Zwave and not consistent echo system I found the broadlink platform quite good specially their power socket which keeps a history of the power use and current use for any appliance. Very Good to monitor fridge and AC http://www.aliexpress.com/item/Broadlink-SP2-EU-Smart-Home-Wireless-Remote-Control-Electrical-Smart-Plugs-Sockets-By-app-control-switch/32655943437.html I also use the battery monitor to check on battery from bedroom - found good to be 40-60 metrs in open adn 10-20 meters through one wall http://www.aliexpress.com/item/NEW-MHF-120S-Wireless-DC-Voltmeter-Ammeter-Power-Meter-0-120V-100A-Shunt-MHF120100S/32611336909.html 2 Likes |

guys i need your advice. i want to attach an external smart charger to my bank 48v 200ah. what my supplier brought was a rectifer. he claims telcoms use it for their batteries. (48v50amps). is this a smart charger . i dont want something to damage my bank for nothing. |
Re: Solar Energy, A Complement To FTA by pranil(m): 10:12am On Aug 08, 2016 |
samnaija: 200 Ah requires max 20 to 25 Amps C10 rate batteries. Anything more and you will damage the battries unless the charger can adjust current and monitor temperature . If you are willing to order from Aliexpress I can send you link for a very good charger . or altrenatively look on this website and find a way to order http://www.meanwell.com/product/inverter/inverter01.html I found it very difficult to locate a good charger at that capacities as normally it is integrated in inverters 2 Likes |

Braaad: Check any electronics spares market ( Oshodi/alaba if you are in Lagos). I also learnt that Binatone stabilizers use toroidal transformers. Prag stabilizers also use toroidal transformers. you can stack smaller torids to get 10KVA (any particular project in mind?) |
Re: Solar Energy, A Complement To FTA by Wazari: 6:09am On Aug 12, 2016 |
Hello Everyone, I am one of the silent majority that has been reading but not commenting for a long time. This thread has been very informative and helpful to me. I just acquired some quanta 12V 200Ah AGM batteries and I'm not sure of the correct bulk and float voltages. Quanta manuals and website strongly advice 13.8V bulk and 13.5V float (discouraging even a 1% increase) but all other online resources I have found recommend approx. 14.4V bulk and 13.8 -13.4V float. Personally I think the manufacturers recommendation is on the low side, probably more suited to float usage and would not lead to a fully charged battery under cyclic usage. I have the batteries set at 14.4V and 13.6V but I'm concerned about over charging the batteries. What do you guys think? |

My people,I just received this panel I ordered through konga. It looks really strange without the cell terminals in front of the cells. I don't even want to test it yet. Please can anyone tell me this is not a fake. Nairalanders what do you guys think.

Trippledots:Pointing to ur No 3, the difference in Voltage will be converted to current via an Mppt Controller. The more the difference, the greater the harvest, provided Mppt is in play. To No 1, I may be wrong and stand to be corrected, but I think distance matters between the charge controller and battery bank. it is advised to maintain the shortest distance possible from charge controller to your battery bank to improve efficiency. 4 Likes 2 Shares |

Re: Solar Energy, A Complement To FTA by iLoveTheSun(m): 1:20pm On Aug 14, 2016 |
@anidat77 Can you please upload a picture of the name/type plate please?! Your module is made of back contact cells, those are manufactured by Sunpower et al. They have one of the highest efficiency in the market, because there are no frontside bars. There are small holes that lead the front to the backside. I have a solar installation with Sunpower modules as well. Each module (1,65 x 1,05m) is 310 Watts(peak)! The open-current voltage is higher than other solar modules. So, you need to get the right solar charger. sunny regards, |
Re: Solar Energy, A Complement To FTA by iLoveTheSun(m): 1:26pm On Aug 14, 2016 |
Oh, the solar boat and the solar plane Impulse 1 & 2 are made of those high-efficiency back contact cells from Sunpower. (>21%) By the way, the preceding company (the original technology) of Sunpower was a solar cell manufacturer for satellites. The founders started Sunpower and went public on NASDAQ. In the meanwhile the French Oil company TOTAL took a big share of Sunpower. Because Sunpower/Total is active as Independent Energy Provider, building their own solar parks, it is hard to get their solar modules. BenQ Taiwan has signed a contract to build solar modules with Sunpower cells. Those are the most expensive ones. - like a Mercedes. |
