Deye SUN-5K-SG05LP3-EU three-phase hybrid inverter 5kW 2 MPPT 48V LV battery
The Deye SUN-5K-SG05LP3-EU is a three-phase 5kW hybrid inverter from the SG05LP3 series, designed for residential and small commercial PV systems with 48V low-voltage storage. It combines grid inverter, MPPT charge controller and bidirectional battery charger in a single unit, managing self-consumption, storage, grid feed-in and off-grid operation, with a backup output that keeps essential loads running during a blackout.
It offers 2 independent MPPT trackers, up to 8000W of PV input power and a battery charge/discharge current of up to 120A. The transformer-isolated battery side and support for both lithium and lead-acid banks make it suitable for new installations as well as retrofits of existing systems, including AC coupling. IP65 protection, intelligent air cooling and up to 10 units in parallel.
