The differences that matter
Values declared by the manufacturer. - Sixteen inverter brands on the BYD list vs one SMA model (Sunny Boy Smart Energy, single-phase) → with another brand's inverter, a three-phase one or an old Sunny Boy Storage, the SMA is out; a single SMA module does not work with the Sunny Tripower Smart Energy, which needs at least two. - 10.24 kWh usable, up to 38.4 expanded, vs 3.28 kWh, up to 16.4 → how much of the day's energy you can shift to the evening; the SMA starts small and grows from one to four modules. - Warranty 10 years vs 2 → the SMA states 8000 cycles, but its two-year warranty ends long before them. - 167 kg floor-standing vs 38 kg wall-mounted → the BYD takes floor space and a lot of weight; the SMA hangs on a wall.
Which one to choose
Choose BYD Battery-Box Premium HVS 10.2 if…
your PV system has an inverter from one of the sixteen listed brands and you want to shift a lot of energy into the evening, with a spot on the floor for a 167 kg unit. You accept the weight and the footprint.
Choose SMA Home Storage 3.2 if…
you are building around the single-phase SMA Sunny Boy Smart Energy and want to start small, hanging one 38 kg module on a wall and adding up to four in total. You accept a single compatible inverter and a two-year warranty.
