The AC coupled advantage
Enphase’s distributed architecture is the clear choice for retrofits
Enphase AC Battery
No need to replace existing inverters
DC coupled battery with string & DC optimizers
Must upsize inverter to accommodate battery

Evolution of use cases for storage
Today
Aggregated grid services – Supporting grid stability
ToU optimization – moving energy from lower to higher ToU periods
Self-consumption – storing excess PV power to offset expensive rates Time
Backup – storing power for use during a grid power outage Off-grid – being energy self-sufficient without reliance on the grid
