Solar Power Inverter

40W-75WSolar Power Generating SystemEmergency Power


Solar power generating systems take advantage of this property to convert sunlight directly into electrical energy which gets stored in battery and can be used for variety of applications, including emergency power supply and remote power where traditional infrastructure is unavailable.
This system is consists of an electronic box containing the battery, Solar panel, LED Bulbs, DC tower fan and TV (optional). Also it has multiple output sockets of 12V each and USB sockets of 5W each. The LED bulbs are design in such way that it provides light output at par with 14W CFL from each lamp. The product is equipped with all required protections with a special arrangement to prevent deep discharging of battery.

Pretty well.. Decent product.

I am using it for my shop. It has Long backup.. complete primary needs.

1. Backup for long time
2. Can connect external battery for extra backup time.
3. Mobile charging is therefore
4. Easy installation - only connect cable, thats all.

1. Works only with DC powered devices only

Ask a Question

What is an inverter?

An inverter takes DC power (battery or solar, for example) and converts it into AC "household" power for running electronic equipment and appliances.

What is Sine wave ?

It is the ideal waveform for the transfer of AC power. There are two types of waveforms available. A "modified sine wave", and the "true sine wave".
Modified Sine Wave -The modified sine wave is not really a sine wave at all. It is more less a "stepped wave". It achieves voltage regulation by varying in width according to the battery voltage and the load. Thus, the wave is not as smooth as a sine wave. The quality of modified sine wave inverters should not be underestimated. They are highly capable, and (by narrowing the waveform) they save energy when running only small loads, as happens during most of the day in a typical home. Modified sine inverters have been successful in many thousands of remote home, RV and marine systems since 1986.
True Sine Wave - Also known as Pure Sine Wave, is the most reliable waveform and provides power almost identical to a standard wall outlet. The power produced fully assures that your "sensitive loads" will be correctly powered, with no interference. Some appliances are likely to require Pure Sine Wave including digital clocks, battery chargers, light dimmers, variable speed motors, and audio/visual equipment. For these reasons, true sine wave inverters can be more a more expensive choice.

How do I know which inverter to buy?

Different devices require specific wattages to run correctly and efficiently. Please use this easy formula to determine the correct size inverter:
AMPS x 220 = Watts
Example: 10 Amp Unit X 220 = 2200 Watts

What is the difference between "KVA rating" and "KW rating" of UPS?

The mathematical relation is kW= kVA *pf. where kW is active or useful power and kVA is the vector sum of active power and reactive power. The equation therefore is kW= kVA *pf
