Wonderful! So this thread is still alive?? i thought the recent tsunami swept it away. The rains/cloud cover has really affected me. For the first time in months, i get an LBCO alarm/system shutdown @ 48v. My array is 2000w, and battery bank of 200aH. I suspect i need to double my array, and increase my battery bank to 520aH to escape history repeating itself. What are your thoughts?? p.s: My base is Calabar, and i understand we have the highest rainfall in the country. |

obimind: I bought a 1.4kva inverter. 2 pieces of 200ah battery. The product is MPOWER. So far it's been powering my home appliances without any challenge. The challenge I have now is that my area hardly have light from phcn which leaves me with no option than to charge my inverter with my generator. I'm tired of charging my inverter with generator. If I'm to go for solar, what size of solar panel & what size of mppt charge controller will I go for? pls gurus in the house I await ur reply. chris81964: ...or just go to page 1 of thr thread and see how to make a rough estimate yourself. |
Re: Solar Energy, A Complement To FTA by chris81964(m): 1:01pm On Aug 18, 2014 |
Doubling the array is not necessarily a solution. Check your charge controller first. Is it capable of handling all 2kw? That will be the first suspect. Then I will check my batteries to make sure they are not going bad. 9600 watts in your battery is a lot. I am advocate of more battery, but before you purchase additional batteries check your charge controller. fntekim: Wonderful! So this thread is still alive?? |

fntekim: Wonderful! So this thread is still alive?? Since you are still connected to the grid and you have a good inverter I think you might want to do something to your battery bank. 9600wh is small for a home. At least 200ah more will do. You can add panels latter. Your charge contoller is at it's peak so you'll need another charge controller when you are increasing your panels |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 11:02pm On Aug 18, 2014 |
chris81964: correct! and that's exactly my point. anybody trying to run a hybrid system without batteries may well be living in dreamland. |

bodejohn: brother, ts-rm-2 arrived wafi land safely. its already installed and firing as we speak. thanks a million! now that is one less piece of damaged bos equipment to worry about. next stop will be the bls and i'll be knocking on totalgreen's door for that. hmmmmm! strange! how come i'm getting this feeling that i've been here before?! yeah, that's what thunder & lightning can do to your system! |

I am advocate of more battery, but before you purchase additional batteries check your charge controller.Actually, only 4800wh is available, as i never discharge my batteries beyond 50%. My charge controller is an Outback flexmax 60, its in top notch condition. 48v system with my charge controller limiting at 60A, can handle a 2880w array. From the logs, the highest instantaneous harvest i've seen is 1750w in best weather. i agree i need to double my batteries, but with my array producing so little, my batteries will be undercharged. |
Re: Solar Energy, A Complement To FTA by chris81964(m): 12:12am On Aug 19, 2014 |
fntekim: I it should not have too much difficulty charging your additional batteries. Get the batteries and give that a shot. make sure your cables are adequately sized. They become an issue once you stress your system. |

richmon74:The power supply from the grid in my area is okay. Doubling my battery bank will give me peace of mind. |

For those asking for my consumption... Presently I use four fans, two LED TV 32inches and five energy saver bulbs. Now my question goes again; What size of solar panel will suit my consumption. 2ndly what size of charge controller shld I go for? |

Now my question goes again; What size of solar panel will suit my consumption. 2ndly what size of charge controller shld I go for?I did not read where you told us what you want to charge with the panels. Do you have an inverter and batteries or are you looking to put together a system. If you have an existing system what is the voltage and how many AH do you have? |

Good day, the whole house: I am a very newbie to Nairaland and I was pointed to this forum by a friend that saw my suffering trying to ensure some form of constant power supply to my small establishment 24-7! You cannot imagine my joy when I came here and I saw the colossal work, postings, pictures and info here!!! I am finally home! ! By the way it took me about 3 weeks to read through from page 1 till 71( I guess I missed some good info from the data loss issues ) but I cannot but bow for the gurus in the house!!!!! I am on my tenth generator in 4 years ( both petrol and diesel) with a monthly budget of about 100K on fuel minus maintenance!! Oh I have suffered! My experience with inverter systems have been turbulent (I started with the locally made ones - 3 fire accidents at least) and I could now see my numerous errors plainly! Presently I am using a 1.4kva Sukam 24V system with two 165amp/ 10 hrs batteries and enjoying it. I will definitely upgrade in the next few weeks! Pls do anybody have info for or against Century or Blugate 3.5 kva 24V inverters? Thank you once again guys! |
Re: Solar Energy, A Complement To FTA by chris81964(m): 12:32pm On Aug 21, 2014 |
durodee: I am on my tenth generator in 4 years ( both petrol and diesel) with a monthly budget of about 100K on fuel minus maintenance!! Oh I have suffered! Why are you doing the upgrade? What do you want to accomplish with the upgrade. There are so many inverter brands in the Nigeria market. If you have had good experiences with the Sukam why would you consider another manufacturer? Everyone including me will tell you that the product we sell is the best. The user experience is what is the ultimate arbiter. The fires you experienced could happen with any manufacturer if you have a poor installation. Don't skimp on the quality of the materials and the protection you can add to your systems. There should be an interrupt device and or a fuse between your inverter and battery. The cables you be thick. As thick as you can get away with. |
Re: Solar Energy, A Complement To FTA by durodee(m): 4:29pm On Aug 21, 2014 |
chris81964:Thanks chris81964. I planning an upgrade mainly because my energy need will increase in the next few weeks and my current 1.4kva will not be adequate for my @1.5kwh need nor be able to charge my proposed bank of 8 200amp/c10 12V batteries. I am moving house and the new site is completely off grid. My eventual destination is solar but I want to start with something not too expensive but with the ability to rapidly charge my bank if I am using a genset. I read that Century and Bluegate have a 70amp Max charger that was why my interest. I know sukam has a 3.5kva too but being cash trapped now, I was looking for cheaper but a bit reliable inverter to use meanwhile. The main culprit in the incessant fire incidents was NEPA!!!!! 300v surges fried my stab (Century) and the locally made inverters; seems Sukam was able to performed better - got blown once but easily repaired locally. |
Re: Solar Energy, A Complement To FTA by obimind(m): 6:41pm On Aug 21, 2014 |
chris81964:Yes I have a 1.4kva inverter,24 volts. 2 set of 200ah battery. The connection is in series. |

obimind: Get a 30 AMP charge controller and about 500 Watts in panels and you will be fine. If you can find an MPPT controller at a reasonable price it will be your best bet 1 Like |

This MINI-GRID installation is still ongoing. We've done 36 pcs of 265W Solarworld panels on day one (though it was a half day job) and the remaining 17 will be done the next day. I appreciate every member of this thread that showed up at site to give us their moral support. The details of the complete installation will be on our facebook page 'PBASE Solar' We will welcome any reasonable question as long as it won't infringe on our business privacy. 1 Like

chris81964:Talking abt charge controllers, I must confess that I appreciate the level of enlightenment I've gotten from this thread. How can one distinguish btw an MPPT charge controller & a PWM charge controller? |
Re: Solar Energy, A Complement To FTA by chris81964(m): 4:00pm On Aug 24, 2014 |
obimind:The biggest difference is the price. An MPPT cost almost double. On the outside you can't tell. Some Chinese manufacturers do sell a PWM as MPPT, so be careful. All MPPT have PWM capabilities. If you need to get that extra 30% from your array MPPT is worth the money. |
