General Troubleshooting Guidelines
This section will help you narrow down the source of any problem you may
encounter. Please read the following troubleshooting steps:
1. Check for a Warning or Fault message on the System Control Panel or a Fault
code on the inverter information panel. If a message is displayed, record it
immediately.
2. As soon as possible, record on the form, “Information About Your System” on
page WA–4, the conditions at the time the problem occurred. These details
should include the following as well as any other information asked for on
page page WA–4:
• Loads the XW Inverter/Charger was running or attempting to run
• Battery condition at the time of failure (voltage or battery level, for
example), if known
• Recent sequence of events (for example, charging had just finished, utility
grid had failed but the inverter didn’t come on)
• Any known unusual AC input factors such as low voltage or unstable
generator output
• Extreme conditions which may have existed at the time (temperature or
moisture, for example).
3. Attempt the solution indicated in Table 4-2 on page 4–11 or Table 4-5 on
page 4–18.
4. If your inverter information panel or System Control Panel is not displaying a
Fault light, check the following list to make sure that the present state of the
installation allows proper operation of the unit. See also “Inverter
Troubleshooting” on page 4–5 and “Battery Charger Troubleshooting” on
page 4–8.
p Is the inverter/charger located in a clean, dry, adequately ventilated place?
p Have the AC input breakers opened? If so, your pass-through load may have
exceeded the rating of one or more of the input breakers.
