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

Voltage Problems? See Our Cable Size Chart.
In an independent power system, you generally would find an inverter and battery charger system working to the common goal of providing power. What ties each of these together are the battery cables to supply the power to run to or from the batteries and unfortunately, the most common installation error that will cause voltage
