Battery storage
EcoFlow PowerOcean, installed by Geko
A single-phase hybrid inverter with stackable battery packs, a whole-home backup option and a 15-year warranty. Fitted by our own MCS-certified engineers across England and Wales.
The system
Solar, battery and backup from one system.
PowerOcean pairs a single-phase hybrid inverter with stackable battery packs. The inverter runs your solar panels, charges and discharges the battery, and talks to the grid.
Each battery pack is 5.12 kWh. Start with one and add up to three for about 15 kWh in total. Add EcoFlow's Gateway Backup Box and the whole home can keep running in a power cut.
We also fit Tesla Powerwall 3, Fox ESS and Sigenergy, and recommend the one that suits your home, usage and tariff.
