Battery energy arbitrage calculator
Enter two prices and a battery. It returns the margin per cycle, the break-even efficiency and the cycle-life cost.
Defaults are the page example: PG&E Schedule E-TOU-C summer prices effective 1 June 2026, and the Enphase IQ Battery 5P North America data sheet. The installed cost is a placeholder, not a quote. Energy only: no demand charge, export credit, tax, finance or discounting.
