Facts about our inverters.
Inverters are electronic and not mechanical.They generate electric power from a set of special batteries (deep cycle batteries). When NEPA fails, the inverter draws power from the battery and converts (inverts) this battery power into electric power that can power our household appliances. When NEPA power is restored, the inverter recharges the battery and so the system is self sustaining.
Just like mechanical generators, inverters come in various capacities e.g 0.5 kva,1 kva,2 kva,5 kva,10 kva,20 kva, etc. You just have to compare your budget with the load (household appliances) you want to power.
For instance 49k could get you our 1kva inverter and a 100amps deep cycle battery. This can power a T.V, a decoder, 2 ceiling fans and a few energy saving bulbs. Pls note that we recommend 200amps battery for T.Vs up to and above 32 inches.65k in this case.
125K can get you an inverter and two 200amp batteries that can power your T.V, Decoder, 3 fans, energy saving bulbs and a fridge. With 175k, you can add a freezer to the last example.

How much time do i get before the battery runs down?
Two factors determine how much time one can get before the battery runs down.
1.The first factor is the size and number batteries. The power that the inverter uses comes from the battery. The inverter will continue to supply electric power until the battery runs down. There are three basic battery sizes when it comes to inverter use. They are 100amps, 150amps and 200amps. Any size can be used however, the bigger the battery, the longer it can power the inverter before it runs down. For instance an inverter is used with a 100amp battery to power a 21 inches T.V and a decoder. In this example the 100amp battery can sustain the load for approximately 10 hours. If we were to use a 200amp battery in the above example, the time would double to 20 hours because 200amps is twice the size (capacity) of 100amps. A nice analogy would be to think of the battery as a fuel tank. The bigger your fuel tank, the longer it will take before you run out of fuel.
2.The second factor is energy efficiency. Each time you turn on an appliance, the inverter draws more power from the battery to supply the appliance so energy efficiency is very important. First you must change ALL your lights to energy saving bulbs and then make sure that any appliance not in use is switched off. For instance if you are in the sitting room, you need to turn off all appliances in the bedrooms if there is nobody there to conserve power. These tips can help conserve battery power such that you can even get days of continuous usage without the battery getting recharged.

Is the inverter more cost effective than mechanical generators.
The short answer is a resounding YES. In the short to medium term, the inverter is a lot cheaper, far less stressful than the mechanical generator plus it does generate any noise or smoke pollution. I will illustrate with two examples. A client came to us for an inverter to power his deep freezer, 2 T.Vs, a decoder, laptop, 3 ceiling fans and some energy saving bulbs. The cost of the inverter and three 200 amp deep cycle batteries was 175k. The client was a little unsettled and explained that he didn't realise that it would cost more than a 100k. He said that he already had a mechanical generator that powers the load, what was the rationale in buying an inverter unit for 175k. When we inquired how much money he spent on a daily basis on fuel, he said he spent just 700 naira and gets about 6 hrs.We explained that the 200amp batteries would give him an entire day of power (possibly 2 days with good energy management) not just 6 hours. When we calculated 700 naira daily for a month (30 days), we got 21k monthly, 210k in ten months and 252k yearly. This excludes the cost of generator itself and the cost of oil, maintenance and servicing. When our client saw the analysis, he happily paid for the inverter and has been enjoying constant power.

One of our earliest clients is a pharmaceutical company based in Lagos. They were considering the viability of getting an inverter to power their head office since they already had a big diesel generator. We were asked to asses their load and prepare a proposal justifying the need for an inverter. The information we we got from their accounts department was that they spent between 200k to 250k monthly on diesel for their generator. Our proposal showed that on they would require a 7.5 kva inverter and eight 200amp batteries which cost 516k. The analysis further revealed that worst case scenario (assuming there is no supply from NEPA at all), the batteries would sustain them for a day and half after which the generator would run for 5 hours to recharge the batteries. So worst case scenario, the generator would run once for 5 hours every two days. This meant that they would be saving at least 160k monthly on diesel cost. When management saw that the minimum savings on diesel for four months was more than the total cost of the inverter and batteries, they authorised payment for the inverter unit.
