I am working on an install with SunPower solar panels and I want to use a Solectria PVI60 which is a 60 kW 3 phase inverter. Can it be installed with positive grounding or is it only a negative grounded inverter? If so, when installing the inverter how do you switch the polarity of the grounding?

Solectria PVI60 Inverters can we grounded with either a negative or positive polarity.
The Solectria PVI60 Installation manual shows how to wire the 3 phase inverter with a positive ground.
