ATA Energy Storage System MM
4.2
Functioning with inactive PV panels
The equipment is powered by the ATA system by using the energy stored in the batteries until the photovoltaic panels
are once again active. The stored energy can be used up to a minimum threshold of 30/40% (settable in settings).
Only in the case of this energy not being sufficient will the equipment be powered automatically from the mains.
Should a blackout occur during this phase, the ATA uses the 30/40% of energy remaining in the batteries (UPS function)
to power the equipment.
Once the residual energy has been used up, the system turns off. When the mains or the photovoltaic panels are
reactivated, the ATA Energy Storage System automatically starts up again.
When the battery charger level reaches the threshold value set, ATA Energy Storage System automatically switches to
active panels mode (see section 4.1).
