Description

The Deye SUN-8K-SG05LP3-EU-SM2 is a three-phase 8 kW hybrid inverter for 48 V low-voltage batteries and the ideal centerpiece for an economical self-consumption system. It combines PV generation, battery storage, and the grid in a single device, delivering your self-generated solar power exactly when you need it.

Key Benefits for Your System

High PV reserve: With up to 16,000 W of PV connection capacity and two MPP trackers, even a generously sized roof can be fully utilized.
Reliable backup power: In the event of a grid outage, the inverter keeps supplying your loads – with 100% unbalanced output for flexible load distribution.
Flexibly expandable: Up to 10 units can be connected in parallel, and multiple batteries can be operated in parallel – so the system grows with your needs.
Retrofit-friendly: Thanks to AC coupling, you can integrate an existing solar system into your storage solution at a later stage.

Efficient Control of Your Energy Flow

The Deye SUN-8K-SG05LP3-EU-SM2 operates with a maximum efficiency of 97.6% and feeds surplus solar energy into the battery or grid with minimal losses. Using six freely configurable time periods, you can control battery charging and discharging precisely according to your daily profile – for example, to store cheap grid electricity or to cover load peaks. A charging current of up to 190 A ensures your 48 V storage is charged quickly. Intelligent cooling keeps the device quiet (≤ 55 dB(A)) even under load and reliably within the optimal temperature range. Via Wi-Fi, RS485, and CAN, you can keep track of all operating data at all times, while the IP65 protection rating allows for outdoor installation. If needed, the inverter also supports energy storage from a diesel generator – for maximum supply security even away from a stable grid.
