Indeed..... Yes it is 1v per module when not operating, but still >250V when operating. That means that all code requirements for >250V still apply to the DC wiring such as bonding bushings for conduit as required etc. SolarEdge is making hay off of this safety feature, but this feature is inherent in microinverters as well.

The fact that by hitting the "off" switch on the inverter will reduce the potentially high DC voltage to 1V per unit/module could be an advantage from a safety perspective (maintenance, firemen/utility workers) Labor/time-wise, it is like installing both a microinverter system and a string inverter system together, soooooo.... benn DayStar Renewable Energy Inc. b...@daystarsolar.ca 780-906-7807 HAVE A SUNNY DAY
