Create a 10-word scroll-stopping headline for: Have solar already, looking to add battery for TOU shifting on duke energy | Vibe NC

I've had a 7.8kw array for about a year now and it's been great for daytime offset but my peak hours are 4-9pm when production is already dropping off so I'm still paying full peak rate for most of the evening. Been looking at adding storage specifically for TOU arbitrage since duke's spread is 27c peak vs 11c off peak which seems like solid math on paper.

Narrowed it down to the anker e10 or enphase IQ batteries. The e10 is cheaper per kwh and AC couples with my existing setup which is nice, and it's modular so I can add packs later. Enphase integrates tighter with my microinverters but costs more and I'd need 3 units to get comparable capacity. Anyone here running either of these for TOU on duke and can share what the real monthly savings look like?
