WECO 15kW three-phase hybrid inverter for LV batteries XTR-3 SERIES is a powerful solution for larger residential, business and C&I PV systems where higher output power, advanced PV design and reliable low-voltage battery integration are required. It is intended for projects where energy production, consumption control and backup operation are all important.

The XTR-15K model has a rated power of 15kW, 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 15kW model supports charging and discharging power up to 20kW / 18kW.

WECO XTR-3 15kW provides backup output for selected loads in case of grid failure, depending on the system configuration. The backup output power is 15kW rated and 16.5kVA 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 15kW supports integrated power control and zero export function.
The package includes WiFi dongle and Meter+3CT.
