A solar PV system based on AC modules equipped with ArrayPower Sequenced Inverters™ eliminates the complexity found in conventional DC systems. This reinvisioned system produces grid-quality AC power internally, meaning it can be connected to the grid simply by connecting an AC cable.

With a truly parallel architecture and a distributed design with no single point of failure, systems incorporating sequenced inverters are highly tolerant of shade and module mismatches, improving overall energy yield and system reliability. The design is also inherently safe, with a low-voltage operation that reduces risk for installers, maintenance workers and first responders.

The distributed architecture also greatly increases design and installation flexibility while simplifying cable management. An ArrayPower-based system can accommodate up to 40 Sequenced Inverter-equipped AC modules on a single branch circuit, making scalability simple and reducing the number of cables in a system. The design flexibility of Sequenced Inverter-equipped AC modules allows for maximum utilization of the available rooftop area, resulting in more installed solar capacity per rooftop.

Sequenced Inverter-equipped AC module design simplifies system ownership and service. With conventional systems, the owner/operator must coordinate with multiple vendors for warranty claims and service. With an AC module that incorporates the ArrayPower Sequenced Inverter, there is just one point of contact and one provider for the system – the AC module manufacturer.

The smallest increment of solar modules that can be added to a DC system is typically fourteen. For an ArrayPower enabled AC system, the smallest increment of modules that can added to the system is one. Therefore, the ArrayPower system allows a commercial roof to be fully packed with modules and greatly reduces the design and installation time.
