📌 Key Features & Notes

✔ Works Without Battery: Can operate using solar + grid only if you don’t have a battery installed.
✔ EQ Battery Optimization: Built-in EQ function to prolong battery lifespan.
✔ Multi-Priority Output: Allows selection of power source priorities for load management.
✔ Not Parallel-Expandable: Most 11 kW WHC units do NOT support parallel scaling of additional inverters (single standalone unit).

📈 Typical Applications

Ideal for large homes, offices, small commercial buildings, shops or clinics where reliable solar-plus-battery backup is needed. It supports motors, AC units, freezers, fans, lighting and sensitive electronics within its rated capacity.
