Hi Jerry - I'm guessing you're talking about SunPower's legacy modules that require positive grounding. 327s and 345s (as Marco recommended) shouldn't have any positive grounding requirements, so you should be able to use whatever inverter you'd like as long as the voltage tracking aspects are within spec. Here's a little snip out of SunPower publicly available safety installation manual:
