Software Release Notes

975-0604-01-01 Revision A 15

9. Updated grid/gen entry/exit/regulation voltage offsets in respect of grid/gen

support voltage.

10. Implemented new charge algorithm. The differences from the previous

implementation are:

a) Bulk exiting voltage is Vabs, and exiting timer is 1s (range 1s-1hr, can be

set via XDT). Absorption begins with a 1-hr boost stage where battery

voltage is regulated at Vbulk. Boost stage applies only to the custom

battery type.

b) Absorption exiting current is battery Ahr/50.

c) The battery capacity affects the charging current calculation in a way that

small battery capacity (less than 100Ahr on Xantrex XW6048) will limit the

charging current to the capacity level.

d) 0Ahr battery capacity is deemed that there is no absorption exit current

criteria and absorption only exit when absorption timer (default 3hrs,

range 1min-8hr) expires. Setting the battery capacity to zero will reset the

charging current to its default values.

e) Vbulk and Vabs settings are now totally independent from each other on

SCP.

f) Minimum charge percentage is now 5%.

g) Xantrex XW only waits for other Xantrex XW units to finish absorption

before exiting the absorption stage itself. It will not wait for any other types

of devices, but to exit absorption on its own.

11. Changed the minimum load level to report on all AC ports now to 25W.

12. Added the configurable AC output voltage feature which allows the user to set

the AC output level:

• NA model range: 105-130V.

• EU model range: 205V-255V.

• The new configuration is saved after power off.

13. Widened the battery temperature compensation range to 0-50°C.

14. The minimum AC qualify time (a.k.a. AC Transfer Switch Delay), the period

during which the AC voltage needs to stay stable to be qualified, on both AC1

& AC2 is now adjustable(10s-655s) via Xantrex Xanbus PGN AcXferSwCfg.

15. Addressed JIRA XW-43 which states "If there is an unbalanced load on the

output and the Xantrex XW is either in Grid support or Gen support modes, it

resets after AC is taken out. This behavior doesn't happen every time but once

out of about 5 tries."
