The Solar Extreme is the largest solar and inverter system that Go Power! offers. It is designed for anyone who would like the benefit of solar power to charge their batteries and the ability to use AC appliances when there is no utility power available. For example you can run a microwave, TV, blender, audio sound equipment, computers and more without any “utility grid power”. This kit contains a 480 Watt solar charging kit and a 3000 Watt pure sine wave inverter system. Includes everything you need to hook the solar and inverter system up to your batteries and install the solar panels on a flat surface. It is used for charging your RV, boat, cottage and cabin batteries, while providing you with AC power without the noise of a generator or the fuel and maintenance cost that goes with it. It is also used for multiple week trips. It allows you to take full advantage of available sunlight for faster charging and added reserve capacity. Go Power! recommends at least a 400 amp hour battery bank for this product.
