I have owned a China made HYE 1000 L turbine for the last 3 years, 1 of which is was bladeless. Recently I lowered the 55' tower, modified the tail and fin to fit the size of the rotor per windy nations diy chart and replaced the broken blades with the G5 blades, 80" diameter. It tracks 100% better now but it isn't making much power. The China grid tie inverters that I have lean on the turbine too hard when it comes up to voltage and slows the turbine that it falls below 22v where the inverter turns on. I need to make more speed from the blades before inverter comes online. Was thinking about a dc to dc converter, but the voltage is always changing. Any help would be appreciated.
