The inverter cuts out due to low supply-battery voltage.

Possible cause: Supply battery voltage dropped below the low-voltage cutoff threshold (10.5 V).. Recharge the supply battery or start the engine to allow the charging current distributor to replenish battery voltage.

Roof air conditioner shuts off while inverter remains active.

Possible cause: On B2600 and FJ models, the supply battery's voltage is low, so the charging voltage regulator has disconnected it.. Wait for supply battery voltage to reach the switch-on point of the charging current distributor, or manually restart the air conditioner.
