Power Outage Occurs
Morning - Afternoon
If a power outage occurs, the inverter automatically
stops operating then starts stand-alone operation.
Remote Controller (Example)
When stand-alone operation starts, power is
supplied to the stand-alone outlets starts.
Remote Controller (Example)
The storage batteries are discharged to supplement
power shortages when there is an insufficient
amount of sunlight.
If the amount of sunlight increases, surplus solar
power is used to charge the storage batteries. *1
If power consumption exceeds power output,
stand-alone operation temporarily stops. *2
Remote Controller (Example)
If there is an insufficient amount of sunlight, power
is supplied entirely from the storage batteries. *3
Remote Controller (Example)
If the storage batteries have no charge and the
