NOTES:
The only situation in which the Slave may shut down the Master inverter is
during fault conditions such as high or low battery voltage, overcurrent, or
over-temperature conditions. Both inverters will auto reset after a fault
condition has been cleared. The exception is that an overcurrent condition
will generate a shutdown for both inverters that will require a manual restart
of the system.
Search Mode in Series Stacking
When configured for 120/240-volt series stacking, each inverter/charger
operates independently in search mode and attempts to detect loads
connected to its terminals only.
