PV Powered PowerVault MV-780kW

The PowerVault™ from PV Powered is a fully integrated power conversion solution for MW-scale PV projects that accepts PV DC inputs and provides medium voltage AC output. The PowerVault is built around PV Powered’s line of commercial inverters which offer exceptional reliability and 20+ year operating life. The PowerVault also offers industry-leading efficiency and the widest MPPT input range of any commercial inverter in the industry. This combination of reliability, long life, and maximized energy harvest makes the PowerVault the right choice to maximize return on investment in a MW-scale PV system. The pre-wired outdoor-rated enclosure reduces project engineering costs, accelerates project schedules, and significantly decreases the cost of on-site labor and installation. The entire package is also designated to be pier mounted to further simplify installation.
