Software Release Notes

975-0604-01-01 Revision A 11

10. Changed the fault-set hysteresis to 0V for F48 (DC under voltage fault) to

prevent premature fault triggering. Also changed default fault level to 46V/23V,

and recovery hysteresis to 4V/2V.

11. In order to prevent passive charging, added protection to not qualify AC if DC

voltage is below 40V for 48V system or 20V for 24V system.

12. Added protection to put unit into sleep mode if the DC voltage is below V-

LBCO for more than 24hrs to prevent draining the batteries.

13. Changed the battery over temperature fault level from 70°C to 60°C.

14. Corrected "qual" cmd to display the correct GEN-L1L2 voltage.

15. Changed low battery upper limit from 26V/52V to 29V/58V on AUX output port

to give customer more flexibility.

16. Added soft start for the equalization charge stage.

17. Rebranding from Xantrex to Schneider Electric format.

18. Changed "FREQ" cmd so that it now accepts decimal frequency settings such

as "55.15Hz".

19. Changed AC coupling frequency push limits down to -5Hz.

20. Made phase_error and period_error limits to be configurable via "sync" cmd.

Defaults updated to phase=6(12°), period=250(≈ 2%).

Syntax:

SYNC return the latest readings and current limits

SYNC S # # is a number between 3 and 20. set the new phase limit

SYNC D # # is a number between 15 and 1500. set the new period limit

21. Changes made so that reconfigured AC output voltage is saved after DC

power cycle.

22. Fixed an issue where a unit may be unable to come back on after powering off

through pressing the power button. This issue only happens in multi-unit

setups where the other unit(s) is supplying the Xantrex Xanbus network power.

865-1035 (Xantrex XW6048-EU)

865-1035.01_07_00.BN0005

Build number range: 1.0.0BN29 — 1.7.0BN4

Time range: Apr 21, 2008 — June 16, 2010

1. Fixed Xantrex XW Slave units exhibit Invert delay on Transfer. Now if Search

Mode is disabled, slave units will automatically start to invert on AC fail instead

of waiting for instruction from master.

2. Changed the SHORT_CIRCUIT_CHECK_TIMES from 30 to 120 to change the

short circuit time from 250ms to 1ms at 60Hz.

3. Added rated power derating in charge current calculation.

4. Added hysteresis to address the oscillation issue occurring between grid-

support (or gen support) and peak-load-shaving states when unit is not

precisely calibrated.
