ENERGY FLOW: REGULAR
See if adding battery storage to existing solar pays back from peak vs. off-peak TOU arbitrage—daily savings, payback years, and LCOS.
DoD is how much of the nameplate kWh you actually cycle. Lithium home BESS often allows 80–90% daily DoD; deeper cycling increases arbitrage kWh but accelerates wear and may void warranty limits.
BESS ROI depends entirely on a wide peak vs. off-peak spread—flat tariffs rarely justify storage arbitrage alone. Pair with solar self-consumption for fuller economics.
