Multi-Unit Power System can be used as a grid-tie power backup equipment or as primary power
sources for off-grid sites. They may or may not have solar energy harvest capability or other alter-
nate energy sources.
Electrically, all the power devices are connected to a common AC and DC bus using appropriate
circuit breakers, electrical panels, combiner boxes and/or power distribution panels (PDP).
A full function Multi-Unit Power System is able to harvest energy (store it, regulate it, and distrib-
ute it) through AC breaker panels. If the system is equipped with solar energy harvest capability,
harvested energy that is not stored may be consumed on site, may be exported to the grid, or a
combination of the two depending on the multi-unit configuration.
Multi-Unit Power Systems have different applications, many types and power ratings, and a struc-
ture that forms the system, as described in the following pages.
