What do the "Best for" labels mean?

Labels come from fixed cut-offs in the data: home-storage class, 4kWh+ size, £400 or less per stated kWh, 2.4kW+ output, 10,000+ cycles, or backup power. Connection notes describe installation requirements, rather than permission to use a household socket. Historical prices are marked where a fresh check was blocked.
