WECO 12kW three-phase hybrid inverter for LV batteries XTR-3 SERIES is designed for projects requiring higher PV input capacity, stable three-phase operation and efficient energy management from battery storage. It is suitable for residential and business solar installations with higher energy demand and the need for backup power support.

The XTR-12K model has a rated power of 12kW, 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 and different module orientations.

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 12kW model supports charging and discharging power up to 20kW / 14.5kW.

WECO XTR-3 12kW provides backup output for selected loads in case of grid failure, depending on the system configuration. The backup output power is 12kW rated and 13.2kVA maximum, with an average transfer time of 10ms.

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 12kW supports integrated power control and zero export function.
The package includes WiFi dongle and Meter+3CT.
