Why is my XW/SW shutting down due HBCO/High Battery Voltage?
It may be the HBCO setting is too low. Some people erroneously believe setting HBCO to a low value somehow helps with battery regulation, when in fact, it only shuts down the Inverter/Charger, which
would have no effect on external charging sources that were not regulating properly. It may even exacerbate the situation because the inverter is no longer acting as a load to draw energy out of the battery.
It is acceptable to set HBCO to a lower value so the loss of AC can act to alert the end user of an overcharging condition, however, it is better to use AUX for alarm if loss of AC power is not acceptable.
