SolaX Power Network Technology (Zhe jiang) Co Ltd
The Solax X3-ULT-20K is a 20 kW three-phase hybrid solar inverter from Solax’s X3-ULTRA series. It integrates solar PV conversion, battery charging/discharging, and grid interaction management in a single device suitable for large residential, commercial or industrial PV + storage systems. This hybrid inverter supports flexible PV and battery configurations, smart energy management, and robust protection features — making it ideal for high-yield, grid-interactive systems.
- Product Code:31011
- Model No.:X3-ULT-20K (AS4777-2 2020)
Hybrid Solar + Battery Capability
– Works as both a grid-connected inverter and a battery energy storage controller, enabling surplus PV to be stored and used later for loads or grid export.
Multiple MPPT Trackers
– Typically equipped with 3 MPPTs (6 string inputs) for flexible PV array design and improved energy harvest across different orientations/shade conditions.
High DC Oversizing Support
– Supports up to 200 % PV oversizing relative to AC output, allowing larger PV arrays for maximum generation potential.
Smart Energy & Load Management
– Features smart schedules, time-of-use control, intelligent load response, and ancillary services readiness — supporting modern energy management and virtual power plant (VPP) functions.
Robust Protection & Fast EPS Response
– Includes IP65 weather protection, Type II SPD on AC/DC sides, optional AFCI, and UPS-level switchover (<10 ms) for reliable operation even during grid outages.
