Software Release Notes

16 975-0604-01-01 Revision A

16. Improved charge voltage regulation in a multiunit installation where more than

one unit is charging a Gel type battery bank. Previously, the battery bank can

be over-charged and damaged due to the low impedance present in the Gel

type batteries.

17. Changes made to read input AC current:

• Split-phase models: reading the current from the primary side.

• Single-phase models: reading L1-N current.

18. 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.

19. 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.

20. 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.

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

22. Changed "qual" cmd to display the correct GEN-L1L2 voltage.

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

to give customer more flexibility.

24. Added soft start for the equalization charge stage.

25. Rebranding from Xantrex to Schneider Electric format.

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

as "55.15Hz".

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

28. 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

29. 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.

865-1045 (Xantrex XW4024-EU)

865-1045.01_07_00.BN0005

Build number range: 1.3.0BN20 — 1.7.0BN4

Time range: Aug 10, 2008 — Jan 13, 2010

1. Moved Sell Enable/Disable parameter to non-volatile memory so that its value

is kept after power off.

2. Adjusted the A.I. bounds such that they are less aggressive. This was done to

address customer complaints about how our equipment would not connect to

poorly regulated utilities (which is often the case in the back up market).
