1.1 System Introduction
INTRODUCTION 01
INTRODUCTION INTRODUCTION
AlphaESS SMILE5 (incl. SMILE5-BAT and SMILE-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
schemes show:
1.2 Safety Introduction
1.2.1 Manual Keeping
This manual contains important information about operating the system. Before
operating, please read it very carefully.
The system should be operated in strict accordance with the description in the manual,
