If you want to "DYI", go with Micro-inverters. Most of the time the voltages on string inverters reach near 600V. Some of the new ones can create voltages in the 1000V region. Micro-inverters put out either 120VAC or 240VAC, single phase. Much safer for a DYI.
The biggest issue with DYI is the roof mounting. You want to create a very strong connection and you do not want to create roof leaks.
On our systems, the maximum voltage is around 120VDC. And if you do miss the net metering, our system can create net metering, by storing your excess solar in the battery bank, for use later in the day.
