Deye SUN-8K-SG05LP3-EU-SM2 8 kW Three-Phase Hybrid Inverter
The Deye SUN-8K-SG05LP3-EU-SM2 three-phase hybrid inverter is made for homes and small businesses on a 400 V three-phase connection that want low-voltage storage: 8 kW of rated power on 3L+N+PE, two independent MPP trackers taking up to 12,800 W of modules and a three-phase backup output that takes over when the grid fails. Transformer isolation and 48 V battery management make it compatible with the most common LiFePO4 rack and tower banks.
It works with 48 V LiFePO4 lithium batteries (CAN communication with the BMS) or lead-acid banks, with charge and discharge current up to 190 A, and up to 10 units can be paralleled both on-grid and off-grid as the system grows. Six programmable time slots, an LCD display, Wi-Fi and RS485/CAN ports complete a unit certified to CEI 0-21, EN 50549 and VDE-AR-N 4105, in an IP65 outdoor enclosure.
Key features
Three-phase backupThe emergency output re-powers loads on all three phases when the grid fails, keeping pumps and motors running.
Isolated 48 V storageTransformer isolation design and CAN communication with the BMS make it compatible with 48 V LiFePO4 rack and tower batteries.
Up to 10 units in parallelStart with one inverter and expand in parallel, both on-grid and off-grid, with multiple battery banks in parallel.
Efficiency and protection97.6% peak and 97.0% European efficiency, IP65 enclosure and intelligent air cooling for outdoor installation.
