Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for OEMs in a hurry!



There are two types of inverters, modified sine wave and pure sine wave. The most common is "modified sine wave," which is a square wave with a pause as it passes through zero volts. This pause puts most of the power in the fundamental frequency of 60Hz, but does not eliminate all the higher harmonic frequencies which can cause buzzing in audio and entertainment systems, and can cause probems in some sensitive equipment.

In the modified sine wave inverter the power MOSFET switches are either all the way on or all the way off. This means that there is very little power dissipated in the MOSFETs. This enables the inverter designer to use much smaller transistors and heat sinks than the pure sine wave inverter, and makes the modified sine wave very cheap.

These inverters are pure sine wave inverters, which means that the output is a sine wave, which only contains the fundamental at 60 Hz. Therefore it doesn't radiate or transmit noise to other equipment and is kinder to the electronics that it is powering. It is a good, solid design, and a great price for a pure sine inverter.

In other words it is just like the clean power you have in your home or office.

Installation notes: To draw 300 watts from the inverter you will need to supply about 27 amps at 12 volts of battery power for the input. Plan for large wires. For wire sizing information click here. For 1000 watts of peak power you will need 92 amps of 12 volt battery power. For the 24 volt models divide these currents by two.
