WECO 20kW three-phase hybrid inverter for LV batteries XTR-3 SERIES is the most powerful model in the XTR-3 LV range and is designed for larger business, C&I and more demanding residential PV systems. It is suitable for projects with higher daily consumption, larger PV configurations, stronger LV battery setups and the need for reliable backup power.

The XTR-20K model has a rated power of 20kW, maximum PV input power of 40kW and maximum usable PV power of 30kW. It features 3 independent MPPT trackers, maximum PV input voltage of 1000V and a full-power MPPT voltage range of 160–980V, enabling advanced PV system design with multiple PV strings, different module orientations and higher energy production throughout the day.

On the battery side, the inverter supports low-voltage WECO lithium batteries with a rated battery voltage of 51.2V and an operating voltage range of 40–60V. Battery communication is managed via WECO-CAN, while the 20kW model supports charging and discharging power up to 20kW / 20kW. This makes it suitable for larger LV battery configurations and systems with higher daily energy consumption.

WECO XTR-3 20kW provides backup output for selected loads in case of grid failure, depending on the system configuration. The backup output power is 20kW rated and 22kVA maximum, with an average transfer time of 10ms. The model also supports 150% overload capacity for 10 seconds, which is useful for demanding loads and dynamic consumption profiles.

The inverter features IP65 protection, smart cooling, wall-mounted installation and user interface via LED display and app. BMS communication is managed via RS485 / CAN, meter communication via RS485, and portal connection via Wi-Fi Logger.

WECO XTR-3 20kW supports integrated power control and zero export function, making it suitable for professional solar installations where export limitation and energy control are important.
