4.2KVA HAISIC INVERTER

4.2 kVA Pure Sine Wave Hybrid Inverter is a mid-to-high-capacity inverter ideal for powering a medium to large household, a small business, or an off-grid system. With hybrid functionality, a pure sine wave output, and typically a 48V battery input, this inverter provides clean, reliable power by intelligently managing energy from solar panels, batteries, and the grid (if available).

✅ Benefits of a 4.2 kVA Hybrid Inverter

Reliable Mid-High Capacity Output

Can power multiple appliances such as fans, TVs, laptops, refrigerators, and even air conditioners (depending on load management).

Suitable for powering both residential and small commercial setups.

Hybrid Functionality

Automatically switches between solar, battery, and grid.

Optimizes solar energy use and minimizes reliance on grid power.

Battery-Friendly

Works best with a 48V battery bank, reducing current draw and enhancing battery longevity.

Typically includes smart charging features like temperature compensation and deep discharge protection.

Pure Sine Wave Output

Ensures compatibility with all electronic devices and appliances without causing harm or performance issues.

Expandable for Solar Systems

Can be connected with 3–5 kW of solar panels, making it highly adaptable to increasing energy needs.

🏠 Ideal Applications

Medium to Large Homes: Perfect for running essential loads (lights, fans, kitchen appliances) with added support for air conditioners or pumps.

Off-Grid Cabins or Homes: Supports full solar and battery operation without grid dependence.

Small Businesses or Shops: Can power POS systems, lights, refrigerators, and small machinery.

Backup Power Solution: Works well in areas with unstable grid supply or frequent outages.
