BYD Battery-Box Premium HVS
A proven, flexible HV battery that installers know well and that works with many leading inverters. A safe modular choice; just remember the inverter is a separate purchase.

The natural battery choice if you're fitting (or already have) a SolaX inverter, with tidy integration and big expansion headroom at a competitive price. Less compelling with a non-SolaX inverter.
