The At Large Energy, Powerhouse 300 solar generator combines 300 watts of pure household power (220Vac), with a substantial 346 watt hour battery, to provide ample power on demand, in something that is still portable, weighing in at just 5 kg. Furthermore all At Large Energy solar generators can be charged from their recommended solar panel. Meaning no more petrol or diesel generators.

The Powerhouse 300 is constructed with a tough aluminum alloy body, and uses a high capacity 11.1v/31.2Ah (346Wh) Lithium-Ion battery pack to provide long battery life and capacity.

With a 300 watt ultra pure sine wave inverter, you can enjoy an incredibly clean 300 watts of household power on demand for powering a cabin or tiny house, your whole families camping trip, for use in an emergency or power-cut, powering medial equipment, and powering tools when on a building site without power.  

Power laptops and computers, fans, camping T.V.s, camping refrigerators, printers and any device or appliance that draws up to 300 watts.

In an emergency or power-cut, power your electric garage door, gas hot water system, security system, computers, satellite phones, radios, and any other essential devices without noise, fumes or flammable liquids.
