Operating the AC Bypass Switch

Normal Operation

External AC power passes to the AC Bypass Switch through the inverter to power the load (Figure 3-2).

In this configuration, power passes from the inverter, through the AC Bypass Switch, to the connected load. When external AC power is not available, power from the external DC source is used by the inverter to power the AC loads.

Bypass Operation

External AC power routed through the AC Bypass Switch directly to the AC loads (Figure 3-3).

In this configuration, power passes directly to the connected load, bypassing the inverter (via the AC Bypass Switch). This allows the inverter to be removed from service without affecting the connected load. If the external source of AC becomes unavailable while the Bypass Operation is selected, the load will be dropped.
