Electricity produced from PV Panels will export and at the same time stored in Batteries (Lead Acid or LiFePo4 Battery packs), the same can be utilized after sunset or in power cut durations. But in some of the state governments not permitted this system and off Grid Hybrid only permitted (without export).
The grid tie inverter has following features:
Solar grid sharing
Online monitoring
All data records
Communication with battery
LiFePo4 Batteries
Solar battery sharing
Online firmware update
Real time power monitoring
Battery grid sharing
Online parameter control
Total generation records
Without battery can work (some models)
Power export / no power export / self use - yes on selection
So shall we get electricity during power cuts?
Yes, Produced solar electricity stored in batteries and supports the requirement when solar electricity not available. Excess electricity can be exported to Grid.
