GivEnergy All in One 13.5kWh + 5kW Inverter

GivEnergy's All in One (AIO) is the UK's most-installed integrated battery system. The 13.5kWh capacity matches the Tesla Powerwall 3 — but with a separate 5kW hybrid inverter packaged inside the same IP65 outdoor-rated cabinet, making install both faster and cheaper than competing solutions that need separate components.

The single-unit design eliminates several install pain points: no separate battery cabinet, no hybrid inverter on a different wall, no DC isolator runs between them. GivEnergy's 10-year warranty covers unlimited throughput on PV-only self-consumption (or 135MWh of total throughput where other charge sources are used), with at least 70% of the 13.5kWh capacity retained at the end of the term.

Who it suits

UK homeowners adding storage to an existing solar PV install (AC-coupled), or new solar installs where a single-unit AIO simplifies the planning. Heavy users with 4500+ kWh annual consumption who benefit from the 13.5kWh storage scale.

What I'd watch for

The 5kW inverter is the binding constraint — high-load homes with multiple appliances running simultaneously can saturate it (higher-output 6kW variants of the same 13.5kWh AIO are available). At 195kg, the unit requires proper outdoor footing or wall-mount. The GivEnergy app is functional rather than polished — better than most, less slick than Tesla.
