This product converts solar energy to 220 V AC power and feeds it to the grid. It satisfies the demands of our living and reduces pollution and consumption of fossil energy. Due to its light weight, it can be fast plugged / unplugged and is easy to install and replace by one person. It has a very robust structure of integrated Al die casting to prevent damage even in an earthquake. The crust with high-protection finish can withstand severe environmental influences like desert, salt or high elevation. Fins integrated into the crust, with those at both sides deeper than in the middle, form an air duct for dissipation.
