Software Release Notes

975-0604-01-01 Revision A 3

3. Changed frequency hysteresis from 2hz to 0.5hz.

4. Changed minimum breaker size to 3A.

5. Implemented AC coupling which is defined as:

•In invert mode

• Power (more than 300W) flows into the battery

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

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

configurable via Xantrex XWConfig and Xantrex XWConfigPro.

7. 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.

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.

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 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. The minimum load level to report on all AC ports now is 25W
