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.

- Consider additional enclosures for IP21 models in outdoor installations.
- Coordinate with local utilities for grid integration.
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.
