Sterling Power Quasi (Modified) Sine Wave Inverters

Quasi (or modified) sine wave inverters take a 12V DC power source and closely approximate the shape of the AC waveform that you get from your household electrical sockets, meaning that they can operate about 95% of 240V AC powered equipment. Exceptions to this are electrical appliances that use thyristors (for example bread-makers and washing machines) meaning that they will not operate properly unless they are powered from a pure sine wave supply. For equipment with thyristors please look at our pure sine wave inverter range.

These quasi-sine wave inverters from Sterling Power are robust, reliable units and are more cost-effective than pure sine wave inverters if you are running basic electrical items like kettles, microwaves, hairdryers, fridges, TVs, blenders, laptops, games, consoles etc.  They are a compact size for their output power and incorporate several safety features to protect the inverter and battery from damage.

When selecting your inverter always ensure that you allow plenty of spare capacity so that it is not running at or near its full output. For example, if running a 300W appliance choose the 600W model. This will ensure long-life and reliability.
