Deye SUN-12K-SG04LP3-EU is a cutting-edge three-phase hybrid inverter designed to deliver maximum energy independence and reliability for residential and small commercial installations. Operating with a safe and popular 48V low-voltage battery system, this model combines robust solar generation, intelligent battery management, and grid interaction in a compact, wall-mounted unit. With its high power density and advanced features, it offers a future-proof solution for managing energy costs and ensuring backup power.

Smart Energy Management
The inverter features 6 time periods for programmable battery charging and discharging, allowing users to optimize energy usage based on Time-of-Use (TOU) tariffs. This ensures maximum savings by storing energy when rates are low and using it during peak hours.

UPS Function (EPS Mode)
With a seamless switchover time of less than 10ms, the inverter acts as an uninterruptible power supply (UPS), ensuring critical loads remain operational during grid outages.

Remote Monitoring and O&M
Equipped with Deye’s smart monitoring platform, operators can:
Remotely shut down the system immediately in case of an emergency.
Update firmware and adjust parameters without a site visit.
Monitor real-time PV generation, battery status, and load consumption via a mobile app or web portal.

Comprehensive Protection & Grid Compliance
The unit comes with integrated Type II surge protection for both DC and AC sides, reverse polarity protection, anti-islanding, and ground fault monitoring. It complies with a wide array of international grid codes, including: VDE-AR-N 4105 (Germany), CEI 0-21 (Italy), G99/G98 (UK), IEC 62109 & IEC 61000 series.

Applications
Large Residential Homes;
Small to Medium Commercial Buildings;
Farms and Agricultural Facilities;
Off-grid Communities (when paralleled with multiple units);
AC-coupled Retrofit Projects for existing solar systems.
