WECO 8kW three-phase hybrid inverter H-ESY SERIES is a high-voltage inverter for residential solar systems with energy storage. It is designed for projects that require reliable three-phase hybrid operation, efficient energy use and backup support in case of grid failure.
The H-ESY 8K model has a rated power of 8kW and supports up to 12kW maximum PV power. It features 2 independent MPPT trackers, maximum PV input voltage of 1000V and an MPPT operating range of 180–850V, enabling flexible PV system design with different module orientations.
On the battery side, the inverter supports high-voltage lithium-ion batteries and WECO-CAN communication. For the 8kW model, the maximum charge and discharge power is up to 8.8kW, with a maximum charge/discharge current of 50A / 50A.
WECO H-ESY 8K provides backup output for selected loads, depending on the system configuration. The backup output power is 8kVA rated and 8.8kVA maximum, with a transfer time of ≤10ms.
The inverter features IP65 protection, natural cooling, wall-mounted installation and user interface via LED display and app. BMS communication is managed via CAN, meter communication via RS485, and portal connection via WiFi device.
The package includes WiFi dongle and Meter+3CT.
WECO 8kW three-phase hybrid inverter H-ESY SERIES is available through the
Energetik B2B platform for registered users. Energetik provides B2B distribution of solar equipment for professional solar installers across the EU.
