Deye SUN-10K-SG05LP3-EU-SM2 Hybrid Inverter 10kW Three-Phase
The Deye SUN-10K-SG05LP3-EU-SM2 is a three-phase 10kW hybrid inverter for residential and small-business self-consumption built around a 48V low-voltage battery. A single unit manages the PV array, the grid, the battery and the essential loads, with a backup output that steps in during a blackout and the ability to run a fully unbalanced output across the three phases.
It pairs with any 48V LiFePO4 battery whose BMS talks over CAN or RS485, from rack modules to the tower packs in the Litio Store catalogue, and allows up to 10 units in parallel so the system can grow with the site. The battery stage is transformer-isolated; AC coupling makes it easy to retrofit an existing PV system, and diesel generator support covers installations where the grid is unreliable.
