Understanding Pure Sine Power Inverters
An inverter is a piece of equipment that converts DC battery power into AC 230v mains power. Inverters are available in varying wattage outputs ranging from 150w through to 5000w+. When inverters were first invented, they produced what is called a “Modified” sine wave output. This AC power output back then was suitable for all

Flat v Angle Installation of Solar Panels
The positioning of solar panels determines the power output. The angle of the sun in relationship to the angle of the solar panel determines the maximum power density. The tilt angle has the biggest effect on the efficiency of the solar panel. When the angle of the sun is perpendicular to the solar panel, it

Why Do I Need Power Filtration Protection?
ALL electronic equipment that plugs into AC power should be protected. Without suitable protection, your expensive home theatre, sound system, TV, entertainment centre or computer equipment will likely be damaged by the surges and spikes that afflict our electrical systems. You may not see the damage until the system fails, but it can still be

What's With Solar Panel Warranties?
There is so much confusion with solar panel warranties these days, and in our opinion so many of them are not worth the paper they are written on. There are two forms of warranty commonly used these days – Structural & Power. Let’s focus on structural. This looks at the framing, build/workmanship and design of

DC to DC Converters Explained
Step Up-Step Down, Isolated & Non Isolated, what does it all mean? What is a step up DC to DC Converter? A step-up dc-dc converter is an electronic circuit that raises the DC voltage level from a lower value to a higher value. Assuming an ideal converter (100% efficiency), Input Power = Output Power Input
