The PowerVault solution is a fully integrated power conversion system for MW-scale PV projects that accepts PV DC inputs and provides medium-voltage AC output. The PowerVault solution is built around the PV Powered™ line of commercial inverters, which offers exceptional reliability and 20+ year operating life. The PowerVault solution 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 solution 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.
The enclosure is certified to UL QRNZ for walk-in electrical equipment and houses the inverters, distribution switchboard, and low voltage service power panel. The transformer with integrated medium-voltage switch is a compact and cost-effective choice that enables low-cost, loop-feed installations and minimizes the need for individual pieces of medium-voltage switchgear. The flexible design offers several configuration options to meet local utility requirements and installation preferences.
AE backs all its PV Powered commercial inverters with an industry-leading 10-year warranty, an unprecedented optional 20-year warranty, and the most responsive and experienced service and support team in the business.
