A home battery for solar power. It is not a plug-in device under the UK rules and needs fitting by a registered electrician.

Check price at EcoFlow UKElectrician needed. Battery systems are outside the UK plug-in solar rules. Conflict: this page says set-up "requires no electrician", while EcoFlow's other STREAM pages say UK rules need a registered electrician to hardwire it. Battery systems are outside the UK plug-in rules, so we treat it as electrician-installed.
Not electrical advice. We compare products; we are not electricians. Before you connect a solar kit to your home, ask a qualified electrician to check the socket, the circuit and your consumer unit, and follow the maker's instructions.
