Rockwill Inverter Platform
brief introduction
Leveraging Rockwill industry leading PV inverter platform, the Rockwill platform is a turnkey utility-grade multi-megawatt platform, complete with factory integrated step-up transformers, ring main unit (RMU), and power conversion electronics.
Rockwill platform is a turnkey utility-ready building block for PV installations. Installation is as simple as placing the unit by crane and connecting both ends. Because Roockwill platform is factory integrated, customers save money on field integration labor. Rockwill platform is standard 40 foot container size which can be easily transported.
