Peak shaving
Discharges automatically to cap site load during spikes — fewer demand charges, fewer breaker trips.

Tariff arbitrage
Charges in off-peak/low-price periods; discharges when prices are high. The spread becomes savings.

PV self-consumption
Captures midday surplus and uses it later — less export at low rates, more value on-site.

Resilience
Keeps priority circuits running during outages, according to your safety policy.
