Wrenches,
Los Angeles Department of Water & Power (LADWP), the largest and most 
influential municipal utility in the US is finally going to allow 
transformerless inverters for residential PV systems. Are there any design, 
installation or reliability issues to consider with the SMA and other 
high-frequency transformerless inverters. Can they be mounted on a hot south 
or west wall or do the have to be kept cool in the shade?
