INTRODUCTION INTRODUCTION
AlphaESS Storion-SMILE-T10 (incl. M4856-S, HV50056 and SMILE-T10-INV) can be
applied in DC-coupled systems (mostly new installation), AC-coupled systems (mostly
retrofit) and Hybrid-coupled systems (mostly retrofit, and PV capacity-increase), as the
following scheme:

CAUTION:
For the AC-/ Hybrid-coupled system, unlike DC, two power meters are to be mounted.
In Germany some federal states require that only AC solutions be used if more than 10 kWp
capacity of PV is installed, the meters of grid company must be also installed in the system as
