The Solar Elite kit is a large solar and inverter system. It is designed for anyone that 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. This kit contains a 250 Watt solar charging kit and a 2000 Watt pure sine wave inverter system. The Solar Elite includes everything you need to hook the solar and inverter system up to your batteries and install the solar panels on a flat surface. The Solar Elite is great 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. The Solar Elite is excellent for long weekend and extended trips, and is expandable by adding a GP-RV-125E expansion kit (sold separately) for 375 watts of power. This allows you to take full advantage of available sunlight for faster charging and added capacity. Go Power! recommends at least a 400 ampere hour battery bank for the Solar Elite kit.
