just got my sun g 10-30 volt 300watt GTI hooked up now in parallel with the 2 500 watt 22-60 like leamy and its holding the turbine down in the 12 volt area. With just the two 500's hooked up its in the 24 volt area. The 24 volt area has almost twice the power output im finding.Also i find when i unplug one of the 500's it lets the volts into the upper 20's instead of the lower 20's. any thoughts?
