Product Description
Deye SUN-12K-SG02LP2-US-AM3 is a high-performance split-phase hybrid solar inverter designed specifically for the North American market. With 12kW of rated output power, this versatile inverter integrates solar energy management, battery storage, and grid interaction into a single efficient unit, making it an ideal solution for residential and light commercial applications.
Split-Phase Output for North American Standards
The inverter delivers true split-phase output at 120/240V, conforming to standard North American residential electrical configurations. It supports both 60Hz grid frequency and automatic 50/60Hz adaptation, ensuring seamless integration with local utility requirements. The rated AC output current is 50A, with a maximum continuous AC passthrough capability of 200A from grid to load.
High-Efficiency Power Conversion
With a maximum efficiency of 97.6% and MPPT efficiency exceeding 99%, the SUN-12K-SG02LP2-US-AM3 ensures minimal energy loss during power conversion. The inverter features three independent MPPT (Maximum Power Point Tracking) trackers, each supporting two strings, allowing for flexible solar array configurations even with panels facing different orientations or experiencing partial shading conditions.
Advanced Battery Management
The inverter supports both lead-acid and lithium-ion batteries with a voltage range of 40-60Vdc. It delivers impressive charging and discharging capabilities with a maximum current of 250A, enabling rapid energy storage and retrieval. For lithium batteries, the inverter features self-adaptive BMS (Battery Management System) communication via RS485 or CAN bus, ensuring optimal battery performance and longevity.
Versatile Operating Modes
As a true hybrid inverter, the SUN-12K-SG02LP2-US-AM3 supports multiple operating modes to suit various installation scenarios:
On-Grid Mode: Feed excess solar energy back to the utility grid with programmable power factor adjustment (0.8 leading to 0.8 lagging) and low total harmonic distortion (THDi < 3%);
Off-Grid Mode: Continue powering critical loads during grid outages with peak power capability of twice the rated power for up to 10 seconds;
Backup Mode: Seamless transition to battery power ensures uninterrupted power supply;
Generator Integration: Supports diesel generator connection with dry contact control signal for automatic startup when battery levels are low;
AC Coupling: Can retrofit existing solar systems by connecting to AC-coupled solar installations.
FAQ
Yes, the inverter can operate in on‑grid mode without batteries. In this configuration, it converts solar power directly to AC for self‑consumption or export. However, without batteries, backup functionality during grid outages is not available.
Yes, up to 16 units can be paralleled in both on‑grid and off‑grid configurations to increase total power capacity. Parallel communication ports are provided for synchronized operation and load sharing.
