Power-One (power-one.com) announced U.S. availability of its 250- and 300-watt microinverters. Both have a CEC-rated efficiency of 96% and can be used in residential (240 VAC) or commercial (208 VAC) systems. They can also be used in systems that require positive grounding (SunPower PV modules). They offer module-level maximum power point tracking and monitoring. The data for up to 30 microinverters is collected wirelessly via the Aurora CDD communications hub and system information can be viewed over the Internet through the Aurora Easy View website.
Note: While both Power-One Aurora microinverters and Eltek THEIA HE-t string inverters report CEC values on the specification sheets, these products have just been released and neither inverter line is yet listed on the gosolarcalifornia.com “List of eligible inverters per SB1 Guidelines” as of October 1, 2012.
