How to choose the best Inverters,Solar panels and other power backup



Electricity power supply in the country is quite erratic and the only way to enjoy electricity in Nigeria is to use an alternative source and this could be a solar panel, a fuel-powered generator, or an inverter. A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source. A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process.

DC to AC inverter

Power inverters are simply DC (direct current) to AC (alternating current) converters – they convert the DC energy stored in a battery, to the electric current (AC) that your appliances require. An inverter taps current from the public supply when that is on (or, alternatively, from a power generator), stores that power in its battery bank as DC and converts it to AC when the power supply is gone. That way, the inverter provides the power backup you need, filling the gap in your power supply. The main added value of inverters, which is the key advantage of inverter over power generator, is that inverters do not require consumables like petrol, diesel or oil and virtually incur no running cost. Once bought, it supplies power for free, until a battery-change. A big money saver that you can’t ignore! Besides, good inverters are fully automated, saving you that inconvenience of changeovers, suffered with generators. In addition to running without consumables, a solid inverter requires minimum maintenance, again saving you the huge expenditure otherwise  incurred on maintenance of power generators, especially when used extensively.

Input voltage

A typical power inverter device or circuit requires a relatively stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include:

  • 12 VDC, for smaller consumer and commercial inverters that typically run from a rechargeable 12V lead acid battery.
  • 24 and 48 VDC, which are common standards for home energy systems.
  • 200 to 400 VDC, when power is from photovoltaic solar panels.
  • 300 to 450 VDC, when power is from electric vehicle battery packs in vehicle-to-grid systems.
  • Hundreds of thousands of volts, where the inverter is part of a High voltage direct current power transmission system

24V  Inverter

Solar panels and inverters

Solar panels get energy from the sun to create electricity. Solar panels make renewable energy. A common misconception about solar panels is that they produce energy from the sun’s heat. They actually produce energy from the sun’s light. Unlike a generator, a solar panel is a solid state way of producing electricity, meaning that it has no moving parts. Solar panels are often mounted on rooftops. Commercial or industrial installations are often on trackers mounted on the ground. The trackers point the panel towards the sun as the sun moves across the sky. Solar panels are also commonly used in outer space, where they are one of the few power sources available.

As far as a single solar panels can produce just a limited amount of power, many installations contain several panels. This is known as a photovoltaic array. A photovoltaic installation typically includes an array of solar panels, an inverter, rechargeable batteries (for use at night), a charge controller (a device that prevents the batteries from over-charging), two GFCI circuit breakers(one before the inverter and one after), and interconnection wiring. There is sometimes also a transformer after the inverter, which allows 240 volt split phase appliances (such as a clothes dryer or oven) to be used (the transformer is often part of the inverter and can’t be seen). Everything past the inverter (or transformer if there is one) is set up like a normal utility-fed installation (breaker panel, lights, outlets, switches, etc.). If there is no transformer, only 120 volt devices may be used. Installations without a transformer must be labeled as such on the breaker panel to alert future electricians that 24volt appliances cannot be installed. Some installations have direct current (DC) lighting and possibly DC appliances. The advantage of this is that for DC loads, the losses in the inverter are avoided. These installations will have a separate DC breaker panel connected before the inverter. For safety reasons, DC wiring cannot be run in the same conduit as AC wiring, and DC outlets must not accept an AC plug and vice versa.
Inverter is a power generator that uses battery instead of fuel or diesel. when acquired you don’t need additional cost to run it.


What is the price of Solar panels in Nigeria?

Solar panels and inverter tend to vary in price as it depends on a lot of things such as the manufacturer’s production cost, the shipping cost, exchange rate, custom duty fees, the quality, the size and so on. For more info on the price and availability kindly visit www.kara.com.ng for best deals on solar panel and inverter.
