I'm not sure I get ur question clearly but let me try. My inverter is 1.5kva pure sine wave inverter. D solar array is 250w*3=750w. I have 200AH*2 plus 150AH *2 batteries. Average load is less than 250w except during peak perion when I need to use washing machine n fridge if NEPA is out for long. jt2016: |

OK what I was asking is, since you have 1.5KVA I was wondering if a total load of 1KVA was possible assuming you have gadgets totalling 1KVA will it carry it? Anyway in another development, Let me ask you the following perhaps you can advise me better.. I am planning to procure a used Japanese Hitachi Inverter + battery and then use a locally available solar panel in Nigeria.. what do you think about this? any advise? DMerciful: |

It can power 1kva conveniently. I bought my solar panels from Alaba and of course they were imported from China. I don't really know d Hitachi inverter nor d battery but while I'm OK with used inverters, I am not OK with used batteries. Can you share the model of d Hitachi inverter? jt2016: |

inception101: Either your batteries are bad or your charging system is f*cked. First, take the batteries to a battery recharge, then during the day, change the amount of current coming out from ur controller by sparking. If it shows enough current, simply replace your batteries. |
Re: Thread For Solar System/Electricity Owners in Nigeria. by chris81964(m): 3:53pm On Jul 10, 2016 |
inception101: There are so many variables. So lets eliminate them and then we can get to your problem. 1. How many amp hours are your batteries? 2. What is the size of the controller connected to your 200 watt panels? 200/12 =16 amps. It has to be at least that size. If you have a 100 amp hour battery it will take 6.25 hours of direct sunshine to charge them at the full 200 watts. You know that will never happen because we average less that 4.5 hours a day at this time of the year. And after losses you will never see 200 watts. 3. What is the load total for all the devices you connect to your batteries? Look at your batteries and there are two numbers that represent you bulk and float voltage (cycle and standby use). 13.1 during the charge cycle is below that number. Your batteries need to see 14.4+ V daily during the charge cycle. Some need to see close to 15V. Read what it says on the side of the battery. You don't get to those numbers your batteries are not fully charged and would eventually fail because of sulfation. There is nothing wrong when the battery drops from 13.1 to 12.5 when you take the generator or charge source off. Learn about your batteries and you will get results. Good luck.

Re: Thread For Solar System/Electricity Owners in Nigeria. by BasedOnB: 12:31pm On Jul 12, 2016 |
Hello everyone. I'd appreciate some help here please. I have a basic inverter set up which i've been using for a couple of years without hassles. My inverter is a falcon series 800va 12v sukam inverter, and my current battery is a 150 Ah 12v monilite ('Networking') battery. The battery doesn't last for long anymore but i still get 3-4 hrs on the average from it with my led tv/decoder combo after a full charge (PHCN). I recently moved to an area with non-existent PHCN supply, and so i decided to incorporate a solar panel into the set up to charge the battery. I got a 50W 12V panel and connected it to the battery. The problem is the battery doesn't last long @ all. I didn't use the battery for about 5 days in the hope of getting a full charge. After 5 days, the battery didn't last for 2 hrs after loading my led tv (45W). Right now, it doesn't even last enough for me to charge my phone. It is that bad. Please what could be wrong? The guy that sold the panel to me said i need to get a solar charge controller to charge the battery, but i seriously doubt if it will have any effect whatsoever. I feel the battery isn't just getting enough energy from the 50W solar panel. Is the solar panel too small for the battery? The inverter isn't a solar inverter, but i've been using it since 2012 without issues. I would appreciate your responses please. |

I like to seize this opportunity to appreciate sycophantic goat (OP of this thread). The initiative you had to post this topic has really gone a long way * It has enlightened more people on Inverter (power & solar) * It has created business avenues for more entrepreneurs, biz men & importers * It has opened a training avenue for both trainees & trainers And so much more. It trips me more to know you ain't a biz man nor an entrepreneur and didn't open this thread for bizness nor commercial purpose. I will like to openly tell you that some people do value royalty & on behalf of myself and my entire we agreed to appreciate you in our own little way. Kindly whatsapp 08137539988 N/B Stop being a sycophantic goat. A time has to come when you drop such moniker to grow. Jah Bless 1 Like

Well going through your post, what I'll say is this: 1. For a start it seems your batteries are getting weak and you should try o replace them as soon as possible 2. 1 50W solar Panel is way to small to fully charge a 12V/150AH battery. At full power, it'll take the Solar Panel about 6 days to fully charge your battery (and this is highly unlikely), so it'll take a bit longer than that. 3. You need to hook your solar panels up to or charge controller or what you'll be doing to the batteries is more harm than good. Hope this is helpful to you Sir. BasedOnB: 1 Like |

Hi all. Planning to go add a solar charging system to my existing 1.5kva luminous inverter + 2*200ah samba battery. For good SOLAR charging, please what do you recommend. Guys I jet on the street are just saying, buy 4 panels, buy 3 panels, they are not offering any calculations. I'd also appreciate recommended accessories. Cheers |

@1kinggy: May I ask, where you are located? This is John, residing outside of Nigeria, but I am eager to learn the regional environment, i.e. climate conditions, solar insulation, and to understand the market needs. I have access to a solar insulation simulation software. I've been in the solar business for the past 9 years in Europe. Hopefully, I can give you some advice. Do you have more data on your batteries? My personal advice: get high-quality solar modules. A 12 years product warranty, or 25 years performance warranty is nothing, if the manufacturer/importer goes bankrupt, that happened to most European manufacturers by the way. For my first commercial solar installation (28 kWp), I chose the "cheapest" module available from a brand manufacturer: 160 Watts(peak) Sharp, but for my 2nd solar installation (24 kWp) I took US Sunpower with 305 Watts(peak) per module. Now, in Europe I only sell QCells (German), LG (Korean) and BenQ (Taiwan) with Sunpower cells. The biggest problems we had are with small manufacturers who simply disappeared from the market. Good modules have an annual degradation of less than 0,5%. Bad modules regards, John p.s. this is my very first post on nairaland. Don't know how I landed here, but this is quite an interesting thread! 1 Like |

My advice for sizing: if you have money, go for the worst weather scenario, so that you generate enough power on cloudy days. If you're short on money, then go for the best weather scenario, so you don't waste surplus energy that you cannot store in your battery. And never size your battery too small. The nameplate "200 Ah" is always dependant on the duration of discharge. 2 Likes |

iLoveTheSun: I live in South West, Nigeria. We have abundance of sunlight, but some cloud during rainy season (March - october) and dust during our dry / harmattan season. On the average, 6 -7 hours of good sunlight. (Between 830am - 4 pm, local time). As for market, power generation and distribution is unreliable and a lot of home users are going off grid or adding alternative sources to supplement. So the market is big and still growing if your products are good and affordable. |
