• 5. Standard Development
• TÜV Rheinland together

with Sandia, ASU and Bosch, etc., authorized by U.S. Department of Energy, is developing the micro-inverter standard to include Reliability (see right).

• Once finished, it could

be applied to other big inverters or inverter sub- assemblies, when there is no better one available.
