adeaks: ![]() I will suggest you first take a comprehensive load analysis with your critical load point in view, after which the inverter sizing is determined. Secondly, you also know how long you intend to use the system and at what time per day. Thirdly, you find out how often you get the national grid power supply per day to determine your battery how your battery is charged. This is where the option of including a solar PV comes in. Cos if you have 5-6 hours of national grid supply per day you may not need a solar PV, that will be a waste of resources. This also depends on your power consumption, I mean the loads running at the same time, power management while using this system is one thing that must be considered. Solar powered inverter system is designed by the individuals requirements. You only regret when a careful study is not done before starting the project... |

bigtt76: It's kindoff a simple process and wiring diagrams are available all over the net. It's not like only solar works at a time and only the batteries work at another time, well except for night time when solar power is 0. Now, lets say it's 2pm in the afternoon and your solar panels are producing 400watts and you want to power something that only uses 100watts, what happens is that 100watts of that power is forced to your inverter to run your load, while the remaining 300watts charges your battery. Now, lets say you are still producting 400watts of solar by 2:30pm and you want to run something a bit bigger, like an electric cooking pot of 800watts. Your solar power would provide half of your load power (800watts), while the remaining (only 400watts will come from the battery). As you can see, this is much healthier for your batteries, pulling only 400watts than it would be to pull the whole 800watts alone from the battery without the help of the solar panel. Of course at night, your solar input would be 0 and your batteries would have to pick up the slack for all loads in your house. As per connection, there really is nothing special. You just go from solar, to charge controller, then to the batteries. However, safety features like fuses and breakers need to be taken into consideration, as well as wire sizes, distance and so on. 5 Likes 1 Share |

Re: How my inverter is saving me in this poor power supply and no-fuel situation by Nobody: 10:47pm On Apr 24, 2016 |
the lies these inverter hustlers tell . . 1) you require power to charge the inverter - at least 16 hours for 8 hours supply. the inverter is a supplement to power supply. it is NOT a replacement 2) the batteries will last at most 2 years. and that is not guaranteed since there seems to be a repackaged battery racket, or maybe its just the usual low quality for the nigerian market 3) 90% of the inverters sold are piece-of-sheet that fail in under 6 months. after this the looong story with the seller starts. my advice is to go for a mercury 2.5kva inverter, (modified sine wave) direct from coscharis - it is 22-25K . it is RUGGED. nepa fluctuation, overload, all of that, it will work with those. DO NOT BUY THE PURE SINE WAVE inverter. [a friend bought one and it failed in a week] all these pure sine wave are chock full of electronics that cannot be properly maintained locally. batteries [coscharis] are 50k all these sukam , mopower , luminous etc are overpriced due to bad advice, i bought luminous batteries December last year at 56k . imagine how pissed i was when i went to coscharis and found their batteries were 48k [at the time] . a 2.5kva inverter does not need more than 2 12v batteries [preferably 200ah] you wont even need a rack. just put the batteries on the foam packaging, put the inverter on the batteries and you're good to go. you can opt for rewiring, but you need a COMPETENT ELECTRICIAN if you want to go that route. a lot of the inverter sellers will cut corners and install the cheapest wiring you can find. i know because i recommended one to a friend some years back. i was so ashamed when i went visiting and saw the rubbish job the guy had done. cables looking as if they would catch fire any minute. anyway, like i said, go to coscharis VI. they also have a warehouse in computer village. anyone who tells you you need less than 8 hours to fully charge standard inverter batteries is lying. 10 Likes 2 Shares |

Below is my small 1.2kv mercury inverter with one 200Ah battery. I get well over 12hrs of back up I cant measure how much it saved me but i can tell you the my wife kissed me and said thank you for this. My neighbours envy me, one is planning for his. The sweetest fact is that we can sleep through the heat with fan and no noise from generators. Because of the scarcity, neighbours have been spending a lot on fuel to run generators. The last fuel i bought was a 5litre at N200/litre. I didnt use up to 1hr when light was restored and thats over 3weeks ago, the fuel remains unused. To make the sorry interesting, NEPA started a stupid regime when we have light throughout the day but blackout at night when its required for good night sleep. Guess what, am not bothered as we sleep with fans till when they restore the light. 1 Like

You have a lot of ideas....nice. Some solar charge controllers have auxiliary outputs that can power a relay which in turn can be made to power specific load like freezer. Now as night comes, the charge controller can no longer power the relay which in turn will shutdown d freezer from d inverter system however once mains is restored, it switches d freezer to mains. I can design such a system..contact me on chyke200@gmail.com bigtt76: |

adeaks: of course you can, but what do you want to use it for ![]() That's always the major question. Do you want to just be able to power low power consuming devices ![]() ![]() Are you willing to load shed ![]() You can decide to run heavier loads on your budget, but that would kill the battery fast as batteries have "sweet spots" on their discharge curve that you want to always be in. Deviation from this curve and Peukert's law for battery capacity depreciation starts to come into effect; meaning in general, less battery life and sometimes battery damage. So in short, yes, you can get an inverter battery system for your budget, but you must be fully aware of what your limitations are in order for that to be seen as a good investment in retrospect when looking back after a while. 2 Likes |

parlondy007: Hmmmm. This is a very useful post. You just pointed out something I didn't avert my mind to. The length or peeiod of usage. For someone living in a mini flat who goes out to work very early on weekdays and comes back home very late at night, a 2.5kva inverter seems like overkill especially since it would only be used majorly during the weekends. Solar is definitely out of it, both cost wise and practicability too. Maybe a 1.5Kva would do the magic. But again, how does a layman do a comprehensive load analysis to determine the right size to go for? I've learnt from your post. |
