The XW Inverter/Charger has a fault
and has stopped charging or inverting.
The LED also turns on steadily if the
unit has both a fault and a warning.
Pressing the Equalize button (indicated by the
battery equalization on and off. After this button is pressed, the XW Inverter/
Charger begins the equalization charge after the next charge cycle is complete.
Equalization functions only if AC is present and qualified and the charger is
enabled. Otherwise the inverter/charger generates a "cannot equalize" fault
(W96).
CAUTION: Battery damage
Equalization may damage your battery. Consult your battery supplier for details on
equalize charging for the battery type in your system.
Important:
In a system where more than one device is capable of equalizing batteries
(such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers),
there is no system-wide equalization command for all devices. To equalize with multiple
devices, each would have to be enabled individually. Alternatively, equalization can be
performed using only one device. During the equalization process, one device applies the
equalization charge while the other devices continue to operate in synchronized charge
mode, typically in float (three-stage charging) or no-float (two-stage charging).
