ECI Technology
4.1 EPC mode
In EPC mode, the
AC Mains
is the primary source and DC source works as a backup. When AC mains is present, the
sierra module takes energy from the AC source and feed to:
•
AC Load via a double conversation to provide a pure sine wave.
• DC load
and also charges the battery with a regulated DC.

Battery
The total output power of a module can be shared between the AC load, DC load and charging power based upon the
requirement.
If the AC source is not present, the module seamlessly switches to DC source without impacting the critical loads and
resumes to EPC mode once AC source returns. The transfer time between AC to DC and DC to AC is 0 ms.
The EPC mode provides a higher efficiency of 96% without compromising the purity of the output sine wave.
4.2 Back up mode
In back up mode, module operates in DC source and feed to:
•
AC Load via a double conversation to provide a pure sine wave.
•
DC load directly.
