WECO 12kW three-phase hybrid inverter H-ESY SERIES is designed for three-phase solar systems with energy storage, where efficient solar energy use, battery integration and backup power support are required. It is suitable for residential PV installations that need reliable hybrid operation and smart energy management.
The H-ESY 12K model has a
rated power of 12kW and supports
up to 18kW maximum PV power. The inverter features
2 independent MPPT trackers, maximum PV input voltage of
1000V and an MPPT operating range of
180–850V, allowing 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 12kW model, the maximum charge and discharge power is up to 13.2kW, with a maximum charge/discharge current of
50A / 50A.
WECO H-ESY 12K supports backup output for selected loads, depending on the system configuration. The backup output power is 12kVA rated and 13.2kVA 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 12kW 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.
