Software Release Notes

14 975-0604-01-01 Revision A

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

as "55.15Hz".

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

33. 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

34. 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.

865-1040 (Xantrex XW4548-EU)

865-1040.01_07_00.BN0006

Build number range: 1.3.0BN10 — 1.7.0BN5

Time range: Aug 06, 2008 — June 16, 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).

3. Changed frequency hysteresis from 2hz to 0.5hz

4. Implemented AC coupling which is defined as:

• In invert mode.

• But power (more than 300W) flows into to the battery.

• During AC coupling, current is displayed and the charge LED flashes.

5. AC output voltage and operating frequency (50Hz or 60Hz) are now

configurable via Xantrex XWConfig and Xantrex XWConfigPro.

6. Changed criteria for exiting Peak Load Shaving to 2V above the Low Battery

Cut-Out (LBCO) voltage. The unit exits Grid Support state when battery is 1V

above the LBCO voltage, and re-charge. Previously, the unit would stay in

Peak Load Shaving until the DC Under Voltage Fault (F48) was triggered

which would require a manual clear fault.

7. Changed the way to process SellEn command from SCP: Only process the

enable command when it is more than 15s from the time when the last disable

command was issued. This is a workaround of the issue where after enabling

Sell on SCP, the unit is not Selling.

8. Introduced a new Advance Feature: "Sell Dly 40s" where grid-tie entry/exit

delay can be changed from 20s to 40s. An exception of the delay timer is

when Vbatt is 2V above Vgs, the time will be overridden and unit will enter sell

immediately.
