Equalization Procedure
To start equalizing the batteries, do one of the following:
• On the Conext Setup menu, highlight Equalize and select Enable.
• Press the Equalize button on the inverter information panel for five seconds.
If the Conext XW+ will not perform the equalization, see Warning W96 “Cannot
Equalize” in Table 4-3 on page 4–12.
WARNING
EQUALIZATION HAZARD
Only flooded lead acid batteries should be equalize charged. Hydrogen and
oxygen gases are produced when batteries are equalized and can potentially
cause an explosion if ignited. Corrosive battery acid can escape.
Provide adequate ventilation and remove all sources of ignition, such as open
flames, sparks, electric motors, relays, light switches, etc.
Equalization voltage is significantly higher than nominal battery voltage.
Detach electronics that can be damaged by high DC voltage.
Failure to follow these instructions can result in death or serious injury.
Note:
In a system where more than one device is capable of equalizing batteries
(such as a system including multiple Conext XW+ units and Conext 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).
