It does not necessarily have to be oversized or undersized. With a DC/AC ratio of around 0.9, it is exactly in the ideal range (0.9 - 1.1 is recommended). This means that the system is even slightly undersized, but this has practically no disadvantages and at the same time offers scope for retrofitting additional modules at a later date. Scope of delivery: Deye SUN-20K-SG05LP3-EU-SM2 (20 kW LV hybrid inverter) 1 x Deye SUN-20K-SG05LP3-EU-SM2 inverterAn extremely powerful three-phase hybrid inverter with 20 kW output, integrated LCD colour touchscreen and support for 48V low-voltage battery systems.1 x Wall Mount BracketA solid metal mounting rail for securely fastening the appliance to a load-bearing wall.1 x Wi-Fi stick (data logger)A plug-in communication module for connection to the internet for remote monitoring via Deye Cloud or Solarman app.3 x current transformer (CT)External hinged current transformers for measuring the energy flows at the house connection, necessary for zero feed-in and self-consumption optimisation.1 x set of PV connectors (MC4-compatible)The required pairs of DC plugs (plus and minus) for connecting the PV strings to the inverter.1 x communication cable (BMS)A pre-assembled RJ45 data cable for the connection between the inverter and the battery management system.1 x mounting set (screws and plugs)A set of stainless steel screws and heavy-duty dowels for professional installation of the wall bracket.1 x operating instructions (user manual)A printed manual with detailed installation instructions, circuit diagrams and safety instructions.
