WECO 8kW three-phase hybrid inverter for LV batteries XTR-3 SERIES is suitable for smaller residential and business PV systems where solar generation, low-voltage battery storage and backup power are required. With its three-phase design, LV battery connection and energy management features, it is a practical choice for projects focused on higher self-consumption and better use of generated solar energy.

The XTR-8K model has a rated power of 8kW, maximum PV input power of 25kW and maximum usable PV power of 20kW. It features 2 independent MPPT trackers, maximum PV input voltage of 1000V and a full-power MPPT voltage range of 160–980V, allowing flexible PV system design with 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 8kW model supports charging and discharging power up to 20kW / 9.6kW.

WECO XTR-3 8kW provides backup output for selected loads in case of grid failure, depending on the system configuration. The backup output power is 8kW rated and 8.8kVA 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 8kW also supports integrated power control and zero export function.
The package includes WiFi dongle and Meter+3CT.
