Powerful single-phase storage with big PV headroom.
The Deye SUN-10K-SG02LP1-EU-AM3 is a 10 kW low-voltage (48 V) hybrid inverter for high-demand homes and retrofit projects. It supports on-grid and off-grid operation, AC-coupling to existing PV, parallel expansion up to 16 units, and six programmable charge/discharge periods—a robust core for self-consumption, peak-shaving and backup-oriented designs. 

Why installers choose it

• Serious PV capacity: up to 20,000 W PV access power; max DC PV 16,000 W—ideal for oversizing. 3 MPPT with 2+2+2 strings, MPPT 150–425 V, VOC 500 V, start 125 V. PV input current 26+26+26 A, Isc 44+44+44 A.

• 48 V battery, high currents: lead-acid or Li-ion (40–60 V) with 220 A charge / 220 A discharge on the 10 kW model; Li-ion charging is BMS-adaptive.

• On-/off-grid + AC-couple: retrofit existing PV and operate with or without the grid as needed.

• Scales with demand: parallel up to 16 (on-grid or off-grid) for higher power and redundancy.

• Real-world resilience: 2× rated off-grid surge for 10 s to start motors; AC passthrough (grid→load) 60 A.

Reliability & compliance

• IP65 outdoor-ready enclosure; intelligent air cooling; operating range −40 °C to +60 °C (derating > +45 °C).

• Built-in protections: DC reverse-polarity, AC over-current/over-voltage, short-circuit, thermal, residual-current detection, DC component monitoring; Type II surge (DC/AC); arc-fault interrupter optional.

• Grid codes & EMC: EN 50549-1, CEI 0-21, G99, VDE-AR-N 4105, and more (see datasheet for full list).

Monitoring & comms

• Interfaces RS485 / RS232 / CAN; remote monitoring via Wi-Fi / GPRS / Bluetooth / 4G / LAN (optional).

Efficiency

• Max efficiency 97.6%, Euro 96.5%, MPPT > 99%; THDi < 3%, DC injection < 0.5% In.
