1.0 INTRODUCTION
The Power Panel is a self-contained power conversion center designed around two styles of Trace
inverters: the DR Series and the SW Series. The inverter type determines the physical component layout.
Typically, a power panel contains at least one inverter, ac and dc disconnect circuit breakers, and a battery
temperature sensor. Optional PV solar controllers and disconnects can be added to the system at the time of
order, or added later. The inverters, controllers (if ordered) and protection circuitry are fully integrated into a
single enclosure to ensure safety and reliability. Each power panel is ETL listed to UL standard 1741 (Draft),
and comes pre-wired and tested at the factory to maximize system performance and ease of operation.
Installing a power panel is as simple as mounting it to the wall and connecting a dc source (PV array,
batteries, etc.), an ac source (utility power, generator, etc.), and ac loads (via a sub-panel).
