I recently installed a wind turbine using the Rover 300 W generator and a 300 W invertor to tie the windturbine to the grid. The invertor needs a 450W 3 ohm dump load resistor and I do not know where to purchase one. Can anyone help me? Also since this is not tied to batteries do I need to have a charge controller?
You do not need a charge controller. We do sell 2.9 ohm resistors: http://www.windynation.com/products/accessories/dump-loads/300-watt-dump-load-24-volt-systems and one of the above dump loads should be be fine for your particular application. Here is a link to the technical specification of our 2.9 Ohm resistor http://www.windynation.com/manuals/300-watt-dump-load-24-volt-technical-specifications
