Compact, high-efficiency single-phase storage for homes and retrofits.
The Deye SUN-6K-SG05LP1-EU is a 6 kW low-voltage (48 V) hybrid inverter that supports on-grid and off-grid operation, AC-coupling to existing PV, parallel expansion up to 16 units, and six programmable charge/discharge periods—making it a robust core for self-consumption, peak-shaving and backup-ready designs.

Why installers choose it
• PV flexibility: up to 12,000 W PV access power; 2 MPPT (1+1 strings); MPPT 150–425 V, VOC 500 V; max PV input current 13+13 A, Isc 17+17 A.
• 48 V battery, high currents: lead-acid or Li-ion (40–60 V) with 135 A charge / 135 A discharge on the 6 kW model; Li-ion charging is BMS-adaptive.
• On-/off-grid + AC-couple: retrofit existing PV and run with or without the grid as needed.
• Scales with demand: parallel up to 16 units (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) 40 A.

Reliability & compliance
