Deye SUN-5K-SG04LP3-EU Hybrid Inverter 5kW Three-Phase Low Voltage
The Deye SUN-5K-SG04LP3-EU is the 5kW three-phase hybrid inverter for homes and small businesses that already have a 400V supply and want PV, 48V storage and backup power in a single unit. Two MPPT accept up to 7,500W of panels over a 200-650V range.
On the battery side it works between 40 and 60V with 120A of charge and discharge, so it pairs with 51.2V LiFePO4 rack or wall modules; it also supports a diesel generator and up to 10 units in parallel. IP65 protection, noise below 55 dB and compliance with CEI 0-21 and EN 50549 allow outdoor installation, with no need for a technical room.
