Power Inverter Modified Sine Wave 300W 12V DC To AC M8051

SKU: 9321758240281


This compact 300W modified sine wave power inverter is ideal for providing AC power to appliances whilst away from mains power. They connect to your vehicle or auxiliary battery and provide AC power for appliances such as laptop chargers, stereos, phone chargers and other low wattage mains appliances.

This range has been designed with operational safety in mind and is protected against over voltage, over load, over temperature, reverse polarity and short circuit conditions. A USB port is provided on the connection panel for convenient recharging of devices without the need to plug in your AC charger. Each model is housed in a robust aluminium extruded case.

About Powerhouse Black Max Inverters
Housed in a rugged aluminium extrusion, this range of Powerhouse inverters was chosen over many others during testing for their robust reliability and unwavering performance - even under severe operating conditions. All others we tested failed our brutal testing regime. We understand that in the field, inverters will be subjected to all kinds of gross overloads and temperature variations and must survive.

To be considered for inclusion to our range these inverters had to pass all of our tests. Further, as added peace of mind all models have been submitted and certified to Australian Standard AS/NZS 4763.2011. Many other inverters being sold in Australia are not certified and virtually all would not pass without major upgrades or modifications.
