Key Features & Technical Highlights
Dual MPPT for LV Three-Phase Systems
The SUN-18/20/21K-G04-LV series incorporates two independent MPPT trackers optimized for low-voltage three-phase grid connections. Each MPPT supports 3 strings (3+3 configuration), enabling flexible array designs across different roof orientations or partial shading scenarios.
With a wide MPPT voltage range of 200V to 700V and rated DC bus voltage of 350V, the inverter accommodates various string configurations while maintaining peak efficiency on LV 127V/220V and 133V/230V networks.
Industry-Leading Efficiency
Maximum conversion efficiency of 98.6% combined with MPPT tracking efficiency exceeding 99% minimizes energy losses throughout the system lifetime. This high efficiency directly translates to improved energy yield and faster return on investment for commercial installations.

Model Selection Guide
Selecting between the SUN-18K, SUN-20K, and SUN-21K-G04-LV depends on:
- Array Size: Match PV array DC capacity to inverter input power (DC/AC ratio typically 1.1–1.3×)
- Available LV Service Capacity: Verify main breaker and feeder ampacity can accommodate inverter output current
- Load Profile: Size to typical daytime load for maximum self-consumption in zero-export applications
- Expansion Plans: Consider future load growth when selecting inverter capacity
| Model | AC Output | Max PV Input | Typical Array Size* |
|---|---|---|---|
| SUN-18K-G04-LV | 18 kW | 23.4 kW | 19.8 – 23.4 kWp |
| SUN-20K-G04-LV | 20 kW | 26 kW | 22 – 26 kWp |
| SUN-21K-G04-LV | 21 kW | 27.3 kW | 23.1 – 27.3 kWp |
*Based on DC/AC ratio of 1.1–1.3× for optimal energy harvest in high-irradiance locations.
