Making that change to transformerless unfortunately creates that issue,” Marsh said. “The PV array will end up floating, and usually what that means is about half the modules in the entire system will experience a negative bias relative to ground.””

Interesting, this is perhaps why company Sonnen has a 48VDC powered Radian Inverter to help prevent the need for high panel string voltages in the residential market.
