How we calculate your savings: Your 32kWh battery system shifts 17.5kWh of energy from expensive peak hours (27p/kWh) to cheap overnight rates (7p/kWh), saving 20p per kWh shifted. With your 5kW inverter, the batteries charge in approximately 6.4 hours during the overnight window. We account for 90% round-trip efficiency (10% energy loss), exclude standing charges as they remain constant, and assume 70% of your daily usage occurs during peak hours. Real savings vary based on actual usage patterns, tariff rates, and seasonal variations.
