Real-World GivEnergy Performance
Daily cycle with Octopus Flux (automatic):
06:00–15:00: Solar charges battery + powers home. GivEnergy inverter manages automatically. 15:00–16:00: Battery full. Surplus exports at standard Flux rate (~12p/kWh). 16:00–19:00: GivEnergy automatically discharges battery to grid at peak Flux rate (~24p/kWh). Maximum export income. 19:00–02:00: Home uses grid at standard rate. Battery rests. 02:00–05:00: GivEnergy automatically charges battery from grid at off-peak (~10p/kWh). Full recharge for £0.95. 05:00–06:00: Battery powers home until solar kicks in.
All of this happens automatically — you set the tariff once in the app and the inverter handles everything.
Typical daily earning from Flux arbitrage: - 9.5kWh × (24p export – 10p import) = £1.33/day = £486/year - Plus solar self-consumption savings: £400–£700/year - Total annual GivEnergy value: £886–£1,186
